【 Infinite drop-down list]
[2009-06-13]
Place a control where the drop-down list is to be placed, usually a hidden field
Using XML as the data source, you can directly call the XML form
var XMLDOM = LoadXml("CreateXML.ashx?RootId=15&sd=101");
Root = XMLDOM.documentElement;
You can also use Ajax to call up the data source
var ajax = new XiaoFeng. AjaxRequest();
ajax.Url = "CreateXML.ashx?RootId=15&sd=101";
ajax.CallBack = function(e){
if(e.Error != "undefined")return ;
var Root = e.responseXML.documentElement;
}
var ClassSelect = new SelectClass();
ClassSelect.Source = Root;
ClassSelect.Name = "ClassId";
ClassSelect.FirstOption = [["==Please select==","0"]];
ClassSelect.SelectFirst = true;
ClassSelect.Fun = function(e){}
ClassSelect.Select = "101";
ClassSelect.Run();

Parameter description: Source is the drop-down list. The data source is XMLDOM.
Name is the hidden control ID, usually a hidden field.
FirstOption is the drop-down list. The text displayed in the first line of the list, if you want to have different text for each one, you can set multiple text, for example [["==Please select your province==","0"],["==Please select your city ==","0"],["==Please select your county==","0"]] If FirstOption = "" or FirstOption = [], these words will not be displayed. The default is [["== Please select ==",""]]
SelectFirst is true whether to display the text to be set after loading. False is whether to display the first row of data or the set row. The default is true
Fun This function is The onchange selection event of each drop-down list triggers the interface function
Select defaults to "" for the selected attribute
Run runs this category
