Created by
The JavaScript runtime engine creates a Window object for each BODY or FRAMESET tag. It also creates a Window object to represent each frame defined in a FRAME tag. In addition, you can create other windows by calling the Window.open method. For details on defining a window, see open.
onBlur or onFocus event handler in a FRAMESET tag has no effect.
Window object is the top-level object in the JavaScript client hierarchy. A Window object can represent either a top-level window or a frame inside a frameset. As a matter of convenience, you can think about a Frame object as a Window object that isn't a top-level window. However, there is not really a separate Frame class; these objects really are Window objects, with a very few minor differences:
parent and top properties are references to the window itself. For a frame, the top refers to the topmost browser window, and parent refers to the parent window of the current window.
defaultStatus or status property sets the text appearing in the browser status line. For a frame, setting these properties only sets the status line text when the cursor is over the frame.
self and window properties of a Window object are synonyms for the current window, and you can optionally use them to refer to the current window. For example, you can close the current window by calling the close method of either window or self. You can use these properties to make your code more readable or to disambiguate the property reference self.status from a form called status. See the properties and methods listed below for more examples.
Because the existence of the current window is assumed, you do not have to refer to the name of the window when you call its methods and assign its properties. For example, status="Jump to a new location" is a valid property assignment, and close() is a valid method call.
However, when you open or close a window within an event handler, you must specify window.open() or window.close() instead of simply using open() or close(). Due to the scoping of static objects in JavaScript, a call to close() without specifying an object name is equivalent to document.close().
For the same reason, when you refer to the location object within an event handler, you must specify window.location instead of simply using location. A call to location without specifying an object name is equivalent to document.location, which is a synonym for document.URL.
You can refer to a window's Frame objects in your code by using the frames array. In a window with a FRAMESET tag, the frames array contains an entry for each frame.
A windows lacks event handlers until HTML that contains a BODY or FRAMESET tag is loaded into it.
Examples
Example 1. Windows opening other windows. In the following example, the document in the top window opens a second window, window2, and defines push buttons that open a message window, write to the message window, close the message window, and close window2. The onLoad and onUnload event handlers of the document loaded into window2 display alerts when the window opens and closes.
win1.html, which defines the frames for the first window, contains the following code:
<HTML>
<HEAD>
<TITLE>Window object example: Window 1</TITLE>

Properties
closed
Specifies whether a window is closed.
| Property of |
Window
|
| Read-only | |
| Implemented in | Navigator 3.0 |
Description
The closed property is a boolean value that specifies whether a window has been closed. When a window closes, the window object that represents it continues to exist, and its closed property is set to true.
Use closed to determine whether a window that you opened, and to which you still hold a reference (from the return value of window.open), is still open. Once a window is closed, you should not attempt to manipulate it.
Examples
Example 1. The following code opens a window, win1, then later checks to see if that window has been closed. A function is called depending on whether win1 is closed.
win1=window.open('opener1.html','window1','width=300,height=300')
Example 2. The following code determines if the current window's opener window is still closed, and calls the appropriate function.
...
if (win1.closed)
function1()
else
function2()if (window.opener.closed)
function1()
else
function2() See also
Window.close, Window.open
defaultStatus
The default message displayed in the status bar at the bottom of the window.
| Property of |
Window
|
| Implemented in | Navigator 2.0 |
Security
Navigator 3.0: This property is tainted by default. For information on data tainting, see "JavaScript Security".
Description
The defaultStatus message appears when nothing else is in the status bar. Do not confuse the defaultStatus property with the status property. The status property reflects a priority or transient message in the status bar, such as the message that appears when a mouseOver event occurs over an anchor.
You can set the defaultStatus property at any time. You must return true if you want to set the defaultStatus property in the onMouseOut or onMouseOver event handlers.
Examples
In the following example, the statusSetter function sets both the status and defaultStatus properties in an onMouseOver event handler:
function statusSetter() {
window.defaultStatus = "Click the link for the Netscape home page"
window.status = "Netscape home page"
}<A HREF="http://home.netscape.com"
In the previous example, notice that the
onMouseOver = "statusSetter(); return true">Netscape</A>onMouseOver event handler returns a value of true. You must return true to set status or defaultStatus in an event handler.

Window.status
document
Contains information on the current document, and provides methods for displaying HTML output to the user.
| Property of |
Window
|
| Implemented in | Navigator 2.0 |
Description
The value of this property is the window's associated document object.
frames
An array of objects corresponding to child frames (created with the FRAME tag) in source order.
| Property of |
Window
|
| Read-only | |
| Implemented in | Navigator 2.0 |
You can refer to the child frames of a window by using the
frames array. This array contains an entry for each child frame (created with the FRAME tag) in a window containing a FRAMESET tag; the entries are in source order. For example, if a window contains three child frames whose NAME attributes are fr1, fr2, and fr3, you can refer to the objects in the images array either as:
parent.frames["fr1"]
or as:
parent.frames["fr2"]
parent.frames["fr3"]parent.frames[0]
You can find out how many child frames the window has by using the
parent.frames[1]
parent.frames[2]length property of the Window itself or of the frames array.
The value of each element in the frames array is <object nameAttribute>, where nameAttribute is the NAME attribute of the frame.
history
Contains information on the URLs that the client has visited within a window.
| Property of |
Window
|
| Implemented in | Navigator 3.0 |
Description
The value of this property is the window's associated History object.
innerHeight
Specifies the vertical dimension, in pixels, of the window's content area.
| Property of |
Window
|
| Implemented in | Navigator 4.0 |
Description
To create a window smaller than 100 x 100 pixels, set this property in a signed script.
Security
To set the inner height of a window to a size smaller than 100 x 100 or larger than the screen can accommodate, you need the UniversalBrowserWrite privilege. For information on security in Navigator 4.0, see Chapter 7, "JavaScript Security," in the JavaScript Guide.

Window.innerWidth, Window.outerHeight, Window.outerWidth
innerWidth
Specifies the horizontal dimension, in pixels, of the window's content area.
| Property of |
Window
|
| Implemented in | Navigator 4.0 |
Description
To create a window smaller than 100 x 100 pixels, set this property in a signed script.
Security
To set the inner width of a window to a size smaller than 100 x 100 or larger than the screen can accommodate, you need the UniversalBrowserWrite privilege. For information on security in Navigator 4.0, see Chapter 7, "JavaScript Security," in the JavaScript Guide.
See also
Window.innerHeight, Window.outerHeight, Window.outerWidth
length
The number of child frames in the window.
| Property of |
Window
|
| Read-only | |
| Implemented in | Navigator 2.0 |
Description
This property gives you the same result as using the length property of the frames array.
location
Contains information on the current URL.
| Property of |
Window
|
| Implemented in | Navigator 2.0 |
Description
The value of this property is the window's associated Location object.
locationbar
Represents the browser window's location bar (the region containing the bookmark and URL areas).
| Property of |
Window
|
| Implemented in | Navigator 4.0 |
Description
The value of the locationbar property itself has one property, visible. If true, the location bar is visible; if false, it is hidden.
Security
Setting the value of the location bar's visible property requires the UniversalBrowserWrite privilege. For information on security in Navigator 4.0, see Chapter 7, "JavaScript Security," in the JavaScript Guide.
Examples
The following example would make the referenced window "chromeless" (chromeless windows lack toolbars, scrollbars, status areas, and so on, much like a dialog box) by hiding most of the user interface toolbars:
self.menubar.visible=false;
self.toolbar.visible=false;
self.locationbar.visible=false;
self.personalbar.visible=false;
self.scrollbars.visible=false;
self.statusbar.visible=false;menubar
Represents the browser window's menu bar. This region contains browser's drop-down menus such as File, Edit, View, Go, Communicator, and so on.
| Property of |
Window
|
| Implemented in | Navigator 4.0 |
Description
The value of the menubar property itself one property, visible. If true, the menu bar is visible; if false, it is hidden.
Security
Setting the value of the menu bar's visible property requires the UniversalBrowserWrite privilege. For information on security in Navigator 4.0, see Chapter 7, "JavaScript Security," in the JavaScript Guide.

self.locationbar.visible=false;
self.personalbar.visible=false;
self.scrollbars.visible=false;
self.statusbar.visible=false;name
A string specifying the window's name.
| Property of |
Window
|
| Read-only (2.0); Modifiable (later versions) | |
| Implemented in | Navigator 2.0 |
Security
Navigator 3.0: This property is tainted by default. For information on data tainting, see "JavaScript Security".
Description
In Navigator 2.0, NAME was a read-only property. In later versions, this property is modifiable by your code. This allows you to assign a name to a top-level window.
Examples
In the following example, the first statement creates a window called netscapeWin. The second statement displays the value "netscapeHomePage" in the Alert dialog box, because "netscapeHomePage" is the value of the windowName argument of netscapeWin.
netscapeWin=window.open("http://home.netscape.com","netscapeHomePage")
alert(netscapeWin.name)opener
Specifies the window of the calling document when a window is opened using the open method.
| Property of |
Window
|
| Implemented in | Navigator 3.0 |
Description
When a source document opens a destination window by calling the open method, the opener property specifies the window of the source document. Evaluate the opener property from the destination window.
This property persists across document unload in the opened window.
You can change the opener property at any time.
You may use Window.open to open a new window and then use Window.open on that window to open another window, and so on. In this way, you can end up with a chain of opened windows, each of which has an opener property pointing to the window that opened it.
Communicator allows a maximum of 100 windows to be around at once. If you open window2 from window1 and then are done with window1, be sure to set the opener property of window2 to null. This allows JavaScript to garbage collect window1. If you do not set the opener property to null, the window1 object remains, even though it's no longer really needed.
Examples
Example 1: Close the opener. The following code closes the window that opened the current window. When the opener window closes, opener is unchanged. However, window.opener.name then evaluates to undefined.
window.opener.close()
Example 2: Close the main browser window.
top.opener.close()
Example 3: Evaluate the name of the opener. A window can determine the name of its opener as follows:
document.write("<BR>opener property is " + window.opener.name)
Example 4: Change the value of opener. The following code changes the value of the opener property to null. After this code executes, you cannot close the opener window as shown in Example 1.
window.opener=null
Example 5: Change a property of the opener. The following code changes the background color of the window specified by the opener property.
window.opener.document.bgColor='bisque'

Window.close, Window.open
outerHeight
Specifies the vertical dimension, in pixels, of the window's outside boundary.
| Property of |
Window
|
| Implemented in | Navigator 4.0 |
Description
The outer boundary includes the scroll bars, the status bar, the tool bars, and other "chrome" (window border user interface elements). To create a window smaller than 100 x 100 pixels, set this property in a signed script.
See also
Window.innerWidth, Window.innerHeight, Window.outerWidth

pageXOffset
Provides the current x-position, in pixels, of a window's viewed page.
| Property of |
Window
|
| Read-only | |
| Implemented in | Navigator 4.0 |
Description
The pageXOffset property provides the current x-position of a page as it relates to the upper-left corner of the window's content area. This property is useful when you need to find the current location of the scrolled page before using scrollTo or scrollBy.
Example
The following example returns the x-position of the viewed page.
x = myWindow.pageXOffset
See Also
Window.pageYOffset
pageYOffset
Provides the current y-position, in pixels, of a window's viewed page.
| Property of |
Window
|
| Read-only | |
| Implemented in | Navigator 4.0 |
Description
The pageYOffset property provides the current y-position of a page as it relates to the upper-left corner of the window's content area. This property is useful when you need to find the current location of the scrolled page before using scrollTo or scrollBy.
Example
The following example returns the y-position of the viewed page.
x = myWindow.pageYOffset
See also
Window.pageXOffset
parent
The parent property is the window or frame whose frameset contains the current frame.
| Property of |
Window
|
| Read-only | |
| Implemented in | Navigator 2.0 |
Description
This property is only meaningful for frames; that is, windows that are not top-level windows.
The parent property refers to the FRAMESET window of a frame. Child frames within a frameset refer to sibling frames by using parent in place of the window name in one of the following ways:
parent.frameName
For example, if the fourth frame in a set has
parent.frames[index]NAME="homeFrame", sibling frames can refer to that frame using parent.homeFrame or parent.frames[3].
You can use parent.parent to refer to the "grandparent" frame or window when a FRAMESET tag is nested within a child frame.
The value of the parent property is
<object nameAttribute>
where nameAttribute is the NAME attribute if the parent is a frame, or an internal reference if the parent is a window.
Examples
See examples for Frame.
personalbar
Represents the browser window's personal bar (also called the directories bar). This is the region the user can use for easy access to certain bookmarks.
| Property of |
Window
|
| Implemented in | Navigator 4.0 |
Description
The value of the personalbar property itself one property, visible. If true, the personal bar is visible; if false, it is hidden.
Security
Setting the value of the personal bar's visible property requires the UniversalBrowserWrite privilege. For information on security in Navigator 4.0, see Chapter 7, "JavaScript Security," in the JavaScript Guide.
Examples
The following example would make the referenced window "chromeless" (chromeless windows lack toolbars, scrollbars, status areas, and so on, much like a dialog box) by hiding most of the user interface toolbars:
self.menubar.visible=false;
self.toolbar.visible=false;
self.locationbar.visible=false;
self.personalbar.visible=false;
self.scrollbars.visible=false;
self.statusbar.visible=false;scrollbars
Represents the browser window's vertical and horizontal scroll bars for the document area.
| Property of |
Window
|
| Implemented in | Navigator 4.0 |
Description
The value of the scrollbars property itself has one property, visible. If true, both scrollbars are visible; if false, they are hidden.
Security
Setting the value of the scrollbars' visible property requires the UniversalBrowserWrite privilege. For information on security in Navigator 4.0, see Chapter 7, "JavaScript Security," in the JavaScript Guide.
Examples
The following example would make the referenced window "chromeless" (chromeless windows lack toolbars, scrollbars, status areas, and so on, much like a dialog box) by hiding most of the user interface toolbars:
self.menubar.visible=false;
self.toolbar.visible=false;
self.locationbar.visible=false;
self.personalbar.visible=false;
self.scrollbars.visible=false;
self.statusbar.visible=false;self
The self property is a synonym for the current window.
| Property of |
Window
|
| Read-only | |
| Implemented in | Navigator 2.0 |
Description
The self property refers to the current window. That is, the value of this property is a synonym for the object itself.
Use the self property to disambiguate a window property from a form or form element of the same name. You can also use the self property to make your code more readable.
The value of the self property is
<object nameAttribute>
where nameAttribute is the NAME attribute if self refers to a frame, or an internal reference if self refers to a window.
Examples
In the following example, self.status is used to set the status property of the current window. This usage disambiguates the status property of the current window from a form or form element called status within the current window.
<A HREF=""
onClick="this.href=pickRandomURL()"
onMouseOver="self.status='Pick a random URL' ; return true">
Go!</A>status
Specifies a priority or transient message in the status bar at the bottom of the window, such as the message that appears when a mouseOver event occurs over an anchor.
| Property of |
Window
|
| Implemented in | Navigator 2.0 |
Security
Navigator 3.0: This property is tainted by default. For information on data tainting, see "JavaScript Security".
Description
Do not confuse the status property with the defaultStatus property. The defaultStatus property reflects the default message displayed in the status bar.
You can set the status property at any time. You must return true if you want to set the status property in the onMouseOver event handler.
Examples
Suppose you have created a JavaScript function called pickRandomURL that lets you select a URL at random. You can use the onClick event handler of an anchor to specify a value for the HREF attribute of the anchor dynamically, and the onMouseOver event handler to specify a custom message for the window in the status property:
<A HREF=""
In the preceding example, the
onClick="this.href=pickRandomURL()"
onMouseOver="self.status='Pick a random URL'; return true">
Go!</A>status property of the window is assigned to the window's self property, as self.status.

Window.defaultStatus
statusbar
Represents the browser window's status bar. This is the region containing the security indicator, browser status, and so on.
| Property of |
Window
|
| Implemented in | Navigator 4.0 |
Description
The value of the statusbar property itself one property, visible. If true, the status bar is visible; if false, it is hidden.
Security
Setting the value of the status bar's visible property requires the UniversalBrowserWrite privilege. For information on security in Navigator 4.0, see Chapter 7, "JavaScript Security," in the JavaScript Guide.
Examples
The following example would make the referenced window "chromeless" (chromeless windows lack toolbars, scrollbars, status areas, and so on, much like a dialog box) by hiding most of the user interface toolbars:

self.statusbar.visible=false;toolbar
Represents the browser window's tool bar, containing the navigation buttons, such as Back, Forward, Reload, Home, and so on.
| Property of |
Window
|
| Implemented in | Navigator 4.0 |
Description
The value of the toolbar property itself one property, visible. If true, the tool bar is visible; if false, it is hidden.
Security
Setting the value of the tool bar's visible property requires the UniversalBrowserWrite privilege. For information on security in Navigator 4.0, see Chapter 7, "JavaScript Security," in the JavaScript Guide.
Examples
The following example would make the referenced window "chromeless" (chromeless windows lack toolbars, scrollbars, status areas, and so on, much like a dialog box) by hiding most of the user interface toolbars:

self.toolbar.visible=false;
self.locationbar.visible=false;
self.personalbar.visible=false;
self.scrollbars.visible=false;
self.statusbar.visible=false;top
The top property is a synonym for the topmost browser window, which is a document window or web browser window.
| Property of |
Window
|
| Read-only | |
| Implemented in | Navigator 2.0 |
Description
The top property refers to the topmost window that contains frames or nested framesets. Use the top property to refer to this ancestor window.
The value of the top property is
<object objectReference>
where objectReference is an internal reference.
Examples
The statement top.close() closes the topmost ancestor window.
The statement top.length specifies the number of frames contained within the topmost ancestor window. When the topmost ancestor is defined as follows, top.length returns three:
<FRAMESET COLS="30%,40%,30%">
The following example sets the background color of a frame called
<FRAME SRC=child1.htm NAME="childFrame1">
<FRAME SRC=child2.htm NAME="childFrame2">
<FRAME SRC=child3.htm NAME="childFrame3">
</FRAMESET>myFrame to red. myFrame is a child of the topmost ancestor window.
top.myFrame.document.bgColor="red"
window
The window property is a synonym for the current window or frame.
| Property of |
Window
|
| Read-only | |
| Implemented in | Navigator 2.0 |
Description
The window property refers to the current window or frame. That is, the value of this property is a synonym for the object itself.
Although you can use the window property as a synonym for the current frame, your code may be more readable if you use the self property. For example, window.name and self.name both specify the name of the current frame, but self.name may be easier to understand (because a frame is not displayed as a separate window).
Use the window property to disambiguate a property of the window object from a form or form element of the same name. You can also use the window property to make your code more readable.
The value of the window property is
<object nameAttribute>
where nameAttribute is the NAME attribute if window refers to a frame, or an internal reference if window refers to a window.
Examples
In the following example, window.status is used to set the status property of the current window. This usage disambiguates the status property of the current window from a form called "status" within the current window.
<A HREF=""
onClick="this.href=pickRandomURL()"
onMouseOver="window.status='Pick a random URL' ; return true">
Go!</A> See also

alert method to display a message that does not require a user decision. The message argument specifies a message that the dialog box contains.
You cannot specify a title for an alert dialog box, but you can use the open method to create your own alert dialog box. See open.
Examples
In the following example, the testValue function checks the name entered by a user in the Text object of a form to make sure that it is no more than eight characters in length. This example uses the alert method to prompt the user to enter a valid value.
function testValue(textElement) {
You can call the
if (textElement.length > 8) {
alert("Please enter a name that is 8 characters or less")
}
}testValue function in the onBlur event handler of a form's Text object, as shown in the following example:
Name: <INPUT TYPE="text" NAME="userName"

Calling the back method is equivalent to the user pressing the browser's Back button. That is, back undoes the last step anywhere within the top-level window, whether it occurred in the same frame or in another frame in the tree of frames loaded from the top-level window. In contrast, the history object's back method backs up the current window or frame history one step.
For example, consider the following scenario. While in Frame A, you click the Forward button to change Frame A's content. You then move to Frame B and click the Forward button to change Frame B's content. If you move back to Frame A and call FrameA.back(), the content of Frame B changes (clicking the Back button behaves the same).
If you want to navigate Frame A separately, use FrameA.history.back().
Examples
The following custom buttons perform the same operation as the browser's Back button:
<P><INPUT TYPE="button" VALUE="< Go Back"
onClick="history.back()">
<P><INPUT TYPE="button" VALUE="> Go Back"
onClick="myWindow.back()"> See also
Window.forward, History.back
blur
Removes focus from the specified object.
| Method of |
Window
|
| Implemented in | Navigator 2.0 |
Syntax
blur()
Parameters
None
Description
Use the blur method to remove focus from a specific window or frame. Removing focus from a window sends the window to the background in most windowing systems.

Window.focus
captureEvents
Sets the window to capture all events of the specified type.
| Method of |
Window
|
| Implemented in | Navigator 4.0 |
Syntax
captureEvents(eventType)
Parameters
eventType |
The type of event to be captured. The available event types are listed with the event object.
|
Security
When a window with frames wants to capture events in pages loaded from
different locations (servers), you need to use captureEvents in a signed script
and precede it with enableExternalCapture. You must have the
UniversalBrowserWrite privilege. For more information and an example, see
enableExternalCapture. For information on security in Navigator 4.0, see
Chapter 7, "JavaScript Security," in the JavaScript Guide.

close
Closes the specified window.
| Method of |
Window
|
| Implemented in |
Navigator 2.0: closes any window. Navigator 3.0: closes only windows opened by JavaScript. Navigator 4.0: must use signed scripts to unconditionally close a window. |
Syntax
close()
Parameters
None
Security
Navigator 4.0: To unconditionally close a window, you need the UniversalBrowserWrite privilege. For information on security in Navigator 4.0, see Chapter 7, "JavaScript Security," in the JavaScript Guide.
Description
The close method closes the specified window. If you call close without specifying a windowReference, JavaScript closes the current window.
The close method closes only windows opened by JavaScript using the open method. If you attempt to close any other window, a confirm is generated, which lets the user choose whether the window closes. This is a security feature to prevent "mail bombs" containing self.close(). However, if the window has only one document (the current one) in its session history, the close is allowed without any confirm. This is a special case for one-off windows that need to open other windows and then dispose of themselves.
In event handlers, you must specify window.close() instead of simply using close(). Due to the scoping of static objects in JavaScript, a call to close() without specifying an object name is equivalent to document.close().
window.close()Example 2: Close the main browser window. The following code closes the main browser window.
self.close()
close()
top.opener.close()Example 3. The following example closes the
messageWin window:
messageWin.close()This example assumes that the window was opened in a manner similar to the following:
messageWin=window.open("")
Window.closed, Window.open
confirm
Displays a Confirm dialog box with the specified message and OK and Cancel buttons.
| Method of |
Window
|
| Implemented in | Navigator 2.0 |
Syntax
confirm("message")
Parameters
message | A string. |
Description
A confirm dialog box looks as follows:
confirm method to ask the user to make a decision that requires either an OK or a Cancel. The message argument specifies a message that prompts the user for the decision. The confirm method returns true if the user chooses OK and false if the user chooses Cancel.
You cannot specify a title for a confirm dialog box, but you can use the open method to create your own confirm dialog. See open.
Examples
This example uses the confirm method in the confirmCleanUp function to confirm that the user of an application really wants to quit. If the user chooses OK, the custom cleanUp function closes the application.
function confirmCleanUp() {
You can call the
if (confirm("Are you sure you want to quit this application?")) {
cleanUp()
}
}confirmCleanUp function in the onClick event handler of a form's push button, as shown in the following example:
<INPUT TYPE="button" VALUE="Quit" onClick="confirmCleanUp()">

Window.alert, Window.prompt
disableExternalCapture
Disables external event capturing set by the enableExternalCapture method.
| Method of |
Window
|
| Implemented in | Navigator 4.0 |
Syntax
disableExternalCapture()
Parameters
None
Description
See enableExternalCapture.
enableExternalCapture
Allows a window with frames to capture events in pages loaded from different locations (servers).
| Method of |
Window
|
| Implemented in | Navigator 4.0 |
Syntax
enableExternalCapture()
Parameters
None
Description
Use this method in a signed script requesting UniversalBrowserWrite privileges, and use it before calling the captureEvents method.
If Communicator sees additional scripts that cause the set of principals in effect for the container to be downgraded, it disables external capture of events. Additional calls to enableExternalCapture (after acquiring the UniversalBrowserWrite privilege under the reduced set of principals) can be made to enable external capture again.
Example
In the following example, the window is able to capture all Click events that occur across its frames.
<SCRIPT ARCHIVE="myArchive.jar" ID="2">
function captureClicks() {
netscape.security.PrivilegeManager.enablePrivilege(
"UniversalBrowserWrite");
enableExternalCapture();
captureEvents(Event.CLICK);
...
}</SCRIPT>

Window.disableExternalCapture, Window.captureEvents
find
Finds the specified text string in the contents of the specified window.
| Method of |
Window
|
| Implemented in | Navigator 4.0 |
Syntax
find(string, casesensitive, backward)
Parameters
Returns
true if the string is found; otherwise, false.
Description
When a string is specified, the browser performs a case-insensitive, forward search. If a string is not specified, the method displays the Find dialog box, allowing the user to enter a search string.
focus
Gives focus to the specified object.
| Method of |
Window
|
| Implemented in | Navigator 3.0 |
Syntax
focus()
Parameters
None
Description
Use the focus method to navigate to a specific window or frame, and give it focus. Giving focus to a window brings the window forward in most windowing systems.
In Navigator 3.0, on some platforms, the focus method gives focus to a frame but the focus is not visually apparent (for example, the frame's border is not darkened).
Examples
In the following example, the checkPassword function confirms that a user has entered a valid password. If the password is not valid, the focus method returns focus to the Password object and the select method highlights it so the user can reenter the password.
function checkPassword(userPass) {
This example assumes that the
if (badPassword) {
alert("Please enter your password again.")
userPass.focus()
userPass.select()
}
}Password object is defined as
<INPUT TYPE="password" NAME="userPass">

Window.blur
forward
Points the browser to the next URL in the current history list; equivalent to the user pressing the browser's Forward button
| Method of |
Window
|
| Implemented in | Navigator 4.0 |
Syntax
history.forward()
forward()
Parameters
None
Description
This method performs the same action as a user choosing the Forward button in the browser. The forward method is the same as history.go(1).
When used with the Frame object, forward behaves as follows: While in Frame A, you click the Back button to change Frame A's content. You then move to Frame B and click the Back button to change Frame B's content. If you move back to Frame A and call FrameA.forward(), the content of Frame B changes (clicking the Forward button behaves the same). If you want to navigate Frame A separately, use FrameA.history.forward().
Examples
The following custom buttons perform the same operation as the browser's Forward button:
<P><INPUT TYPE="button" VALUE="< Go Forth"
onClick="history.forward()">
<P><INPUT TYPE="button" VALUE="> Go Forth"
onClick="myWindow.forward()"> See also
Window.back
handleEvent
Invokes the handler for the specified event.
| Method of |
Window
|
| Implemented in | Navigator 4.0 |
Syntax
handleEvent(event)
Parameters
event | The name of an event for which the specified object has an event handler. |
Description
handleEvent works in tandem with captureEvents, releaseEvents, and
routeEvent. For more information, see "Events in Navigator 4.0".
home
Points the browser to the URL specified in preferences as the user's home page; equivalent to the user pressing the browser's Home button.
| Method of |
Window
|
| Implemented in | Navigator 4.0 |
Syntax
home()
Parameters
None
Description
This method performs the same action as a user choosing the Home button in the browser.
moveBy
Moves the window relative to its current position, moving the specified number of pixels.
| Method of |
Window
|
| Implemented in | Navigator 4.0 |
Syntax
moveBy(horizontal, vertical)
Parameters
horizontal | The number of pixels by which to move the window horizontally. |
vertical | The number of pixels by which to move the window vertically. |
Description
This method moves the window by adding or subtracting the specified number of pixels to the current location.
Security
Exceeding any of the boundaries of the screen (to hide some or all of a window) requires signed JavaScript, so a window won't move past the screen boundaries. You need the UniversalBrowserWrite privilege for this. For information on security in Navigator 4.0, see Chapter 7, "JavaScript Security," in the JavaScript Guide.
Examples:
To move the current window 5 pixels up towards the top of the screen (x-axis), and 10 pixels towards the right (y-axis) of the current window position, use this statement:
self.moveBy(-5,10); // relative positioning
See also
Window.moveTo
moveTo
Moves the top-left corner of the window to the specified screen coordinates.
| Method of |
Window
|
| Implemented in | Navigator 4.0 |
Syntax
moveTo(x-coordinate, y-coordinate)
Parameters
x-coordinate | The left edge of the window in screen coordinates. |
y-coordinate | The top edge of the window in screen coordinates. |
Description
This method moves the window to the absolute pixel location indicated by its parameters. The origin of the axes is at absolute position (0,0); this is the upper left-hand corner of the display.
Security
Exceeding any of the boundaries of the screen (to hide some or all of a window) requires signed JavaScript, so a window won't move past the screen boundaries. You need the UniversalBrowserWrite privilege for this. For information on security in Navigator 4.0, see Chapter 7, "JavaScript Security," in the JavaScript Guide.
Examples:
To move the current window to 25 pixels from the top boundary of the screen (x-axis), and 10 pixels from the left boundary of the screen (y-axis), use this statement:

Window.moveBy
open
Opens a new web browser window.
| Method of |
Window
|
| Implemented in |
Navigator 2.0 Navigator 4.0: added several new windowFeatures
|
Syntax
open(URL, windowName, windowFeatures)
Parameters
URL |
A string specifying the URL to open in the new window. See the Location object for a description of the URL components.
|
windowName |
A string specifying the window name to use in the TARGET attribute of a FORM or A tag. windowName can contain only alphanumeric or underscore (_) characters.
|
windowFeatures | (Optional) A string containing a comma-separated list determining whether or not to create various standard window features. These options are described below. |
Description
In event handlers, you must specify window.open() instead of simply using open(). Due to the scoping of static objects in JavaScript, a call to open() without specifying an object name is equivalent to document.open().
The open method opens a new Web browser window on the client, similar to choosing New Navigator Window from the File menu of the browser. The URL argument specifies the URL contained by the new window. If URL is an empty string, a new, empty window is created.
You can use open on an existing window, and if you pass the empty string for the URL, you will get a reference to the existing window, but not load anything into it. You can, for example, then look for properties in the window.
windowFeatures is an optional string containing a comma-separated list of options for the new window (do not include any spaces in this list). After a window is open, you cannot use JavaScript to change the windowFeatures. The features you can specify are:
Many of these features (as noted above) can either be yes or no. For these features, you can use 1 instead of yes and 0 instead of no. If you want to turn a feature on, you can also simply list the feature name in the windowFeatures string.
If windowName does not specify an existing window and you do not supply the windowFeatures parameter, all of the features which have a yes/no choice are yes by default. However, if you do supply the windowFeatures parameter, then the titlebar and hotkeys are still yes by default, but the other features which have a yes/no choice are no by default.
For example, all of the following statements turn on the toolbar option and turn off all other Boolean options:
open("", "messageWindow", "toolbar")
The following statement turn on the location and directories options and turns off all other Boolean options:
open("", "messageWindow", "toolbar=yes")
open("", "messageWindow", "toolbar=1")open("", "messageWindow", "toolbar,directories=yes")
How the alwaysLowered, alwaysRaised, and z-lock features behave depends on the windowing hierarchy of the platform. For example, on Windows, an alwaysLowered or z-locked browser window is below all windows in all open applications. On Macintosh, an alwaysLowered browser window is below all browser windows, but not necessarily below windows in other open applications. Similarly for an alwaysRaised window.
You may use open to open a new window and then use open on that window to open another window, and so on. In this way, you can end up with a chain of opened windows, each of which has an opener property pointing to the window that opened it.
Communicator allows a maximum of 100 windows to be around at once. If you open window2 from window1 and then are done with window1, be sure to set the opener property of window2 to null. This allows JavaScript to garbage collect window1. If you do not set the opener property to null, the window1 object remains, even though it's no longer really needed.
Security
To perform the following operations using the specified screen features, you need the UniversalBrowserWrite privilege:
screenX and screenY.
titlebar.
alwaysRaised, alwaysLowered, or z-lock for any setting.
Examples
Example 1. In the following example, the windowOpener function opens a window and uses write methods to display a message:
function windowOpener() {
Example 2. The following is an
msgWindow=window.open("","displayWindow","menubar=yes")
msgWindow.document.write
("<HEAD><TITLE>Message window</TITLE></HEAD>")
msgWindow.document.write
("<CENTER><BIG><B>Hello, world!</B></BIG></CENTER>")

Window.alert, Window.confirm
releaseEvents
Sets the window or document to release captured events of the specified type, sending the event to objects further along the event hierarchy.
| Method of |
Window
|
| Implemented in | Navigator 4.0 |
Note
If the original target of the event is a window, the window receives the event even if it is set to release that type of event.
Syntax
releaseEvents(eventType)
Parameters
eventType | Type of event to be captured. |
Description
releaseEvents works in tandem with captureEvents, routeEvent, and handleEvent. For more information, see "Events in Navigator 4.0".
resizeBy
Resizes an entire window by moving the window's bottom-right corner by the specified amount.
| Method of |
Window
|
| Implemented in | Navigator 4.0 |
Syntax
resizeBy(horizontal, vertical)
Parameters
horizontal | The number of pixels by which to resize the window horizontally. |
vertical | The number of pixels by which to resize the window vertically. |
Description
This method changes the window's dimensions by setting its outerWidth and outerHeight properties. The upper left-hand corner remains anchored and the lower right-hand corner moves. resizeBy moves the window by adding or subtracting the specified number of pixels to that corner's current location.
Security
Exceeding any of the boundaries of the screen (to hide some or all of a window) requires signed JavaScript, so a window won't move past the screen boundaries. In addition, windows have an enforced minimum size of 100 x 100 pixels; resizing a window to be smaller than this minimum requires signed JavaScript. You need the UniversalBrowserWrite privilege for this. For information on security in Navigator 4.0, see Chapter 7, "JavaScript Security," in the JavaScript Guide.
Examples
To make the current window 5 pixels narrower and 10 pixels taller than its current dimensions, use this statement:
self.resizeBy(-5,10); // relative positioning
See also
Window.resizeTo
resizeTo
Resizes an entire window to the specified pixel dimensions.

Window
|
| Implemented in | Navigator 4.0 |
Syntax
resizeTo(outerWidth, outerHeight)
Parameters
outerWidth | An integer representing the window's width in pixels. |
outerHeight | An integer representing the window's height in pixels. |
Description
This method changes the window's dimensions by setting its outerWidth and outerHeight properties. The upper left-hand corner remains anchored and the lower right-hand corner moves. resizeBy moves to the specified position. The origin of the axes is at absolute position (0,0); this is the upper left-hand corner of the display.

| Method of |
Window
|
| Implemented in | Navigator 4.0 |
Syntax
routeEvent(event)
Parameters
event | Name of the event to be routed. |
Description
If a subobject (document or layer) is also capturing the event, the event is sent to that object. Otherwise, it is sent to its original target.
routeEvent works in tandem with captureEvents, releaseEvents, and handleEvent. For more information, see "Events in Navigator 4.0".
scroll

|
| Implemented in | Navigator 4.0 |
Syntax
scrollBy(horizontal, vertical)
Parameters
horizontal | The number of pixels by which to scroll the viewing area horizontally. |
vertical | The number of pixels by which to scroll the viewing area vertically. |
Description
This method scrolls the content in the window if portions that can't be seen exist outside of the window. scrollBy scrolls the window by adding or subtracting the specified number of pixels to the current scrolled location.
For this method to have an effect the visible property of Window.scrollbars must be true.
Examples
To scroll the current window 5 pixels towards the left and 30 pixels down from the current position, use this statement:
self.scrollBy(-5,30); // relative positioning
See also
Window.scrollTo
scrollTo
Scrolls the viewing area of the window so that the specified point becomes the top-left corner.
| Method of |
Window
|
| Implemented in | Navigator 4.0 |
Syntax
scrollTo(x-coordinate, y-coordinate)
Parameters
x-coordinate | An integer representing the x-coordinate of the viewing area in pixels. |
y-coordinate | An integer representing the y-coordinate of the viewing area in pixels. |
Description
scrollTo replaces scroll. scroll remains for backward compatibility.
The scrollTo method scrolls the content in the window if portions that can't be seen exist outside of the window. For this method to have an effect the visible property of Window.scrollbars must be true.
Examples
Example 1: Scroll the current viewing area. To scroll the current window to the leftmost boundary and 20 pixels down from the top of the window, use this statement:
self.scrollTo(0,20); // absolute positioning
Example 2: Scroll a different viewing area. The following code, which exists in one frame, scrolls the viewing area of a second frame. Two Text objects let the user specify the x and y coordinates. When the user clicks the Go button, the document in frame2 scrolls to the specified coordinates.

Window.clearInterval, Window.setTimeout
setTimeout
Evaluates an expression or calls a function once after a specified number of milliseconds elapses.
| Method of |
Window
|
| Implemented in |
Navigator 2.0: Evaluating an expression. Navigator 4.0: Calling a function. |
Syntax
setTimeout(expression, msec)
setTimeout(function, msec, arg1, ..., argN) Parameters
Description
The setTimeout method evaluates an expression or calls a function after a specified amount of time. It does not act repeatedly. For example, if a setTimeout method specifies five seconds, the expression is evaluated or the function is called after five seconds, not every five seconds. For repetitive timeouts, use the setInterval method.
setTimeout does not stall the script. The script continues immediately (not waiting for the timeout to expire). The call simply schedules an additional future event.
Examples
Example 1. The following example displays an alert message five seconds (5,000 milliseconds) after the user clicks a button. If the user clicks the second button before the alert message is displayed, the timeout is canceled and the alert does not display.
<SCRIPT LANGUAGE="JavaScript">
Example 2. The following example displays the current time in a
function displayAlert() {
alert("5 seconds have elapsed since the button was clicked.")
}
