grammer 756 '' @DESCRIPTION: It generates a name value pair which is represented as <em>{"name": value}</em> in JSON. 757 '' the generation is fully recursive. Thus the value can also be a complex datatype (array in dictionary, etc.) e.g. 758 '' <code> 759 '' <% 760 '' set j = new JSON 761 '' j.toJSON "n", array(RS, dict, false), false 762 '' j.toJSON "n", array(array(), 2, true), false 763 '' % > 764 '' </code> 765 '' @PARAM: name [string]: name of the value (accessible with javascript afterwards). leave empty to get just the value 766 '' @PARAM: val [variant], [int], [float], [array], [object], [dictionary]: value which needs 767 '' to be generated. Conversation of the data types is as follows:<br> 768 '' - <strong>ASP datatype -> JavaScript datatype</strong> 769 '' - NOTHING, NULL -> null 770 '' - INT, DOUBLE -> number 771 '' - STRING -> string 772 '' - BOOLEAN -> bool 773 '' - ARRAY -> array 774 '' - DICTIONARY -> Represents it as name value pairs. Each key is accessible as property afterwards. json will look like <code>"name": {"key1": "some value", "key2": "other value"}</code> 775 '' - <em>multidimensional array</em> -> Generates a 1-dimensional array (flat) with all values of the multidimensional array 776 '' - <em>request</em> object -> every property and collection (cookies, form, querystring, etc) of the asp request object is exposed as an item of a dictionary. Property names are <strong>lowercase</strong>. e.g. <em>servervariables</em>. 777 '' - OBJECT -> name of the type (if unknown type) or all its properties (if class implements <em>reflect()</em> method) 778 '' Implement a <strong>reflect()</strong> function if you want your custom classes to be recognized. The function must return 779 '' a dictionary where the key holds the property name and the value its value.
