Class Reset

              org.apache.struts2.components.Reset

public class Reset
extends FormButton

Render a reset button. The reset tag is used together with the form tag to provide form resetting. The reset can have two different types of rendering:

• input: renders as html <input type="reset"...>
• button: renders as html <button type="reset"...>

Please note that the button type has advantages by adding the possibility to seperate the submitted value from the text shown on the button face, but has issues with Microsoft Internet Explorer at least up to 6.0

Examples

 
 <s:reset value="%{'Reset'}" />
 
 

 
 Render an button reset:
 <s:reset type="button" value="%{'Reset'}" label="Reset the form"/>

A contract that requires each concrete UI Tag to specify which template should be used as a default.

Overrides:

evaluateParams in class UIBean

supportsImageType in class FormButton

false to indicate type image is supported.

public void setLabel(java.lang.String label)
