【无限级下拉列表】
[2009-06-13]
在要放置下拉列表的地方放置一控件，一般为隐藏域
以XML为数据源可以用直接调用 XML 形式
var XMLDOM = LoadXml("CreateXML.ashx?RootId=15&sd=101");
Root = XMLDOM.documentElement;
也可以用Ajax调出数据源
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 = [["==请选择==","0"]];
ClassSelect.SelectFirst = true;
ClassSelect.Fun = function(e){}
ClassSelect.Select = "101";
ClassSelect.Run();

参数说明：Source 为本下拉列表数据源 为 XMLDOM
Name 为隐藏控件ID 一般为隐藏域
FirstOption 为下拉列表第一行显示的文字，如果想给每个都有不同的可以设置多个 例如[["==请选择所在的省份==","0"],["==请选择所在的市份==","0"],["==请选择所在的县份==","0"]] 如果 FirstOption = "" 或 FirstOption = [] 则不显示这些文字 默认 为[["==请选择==",""]]
SelectFirst 为是加载完后是否显示要设置的文字 true 为显不 false 为显示数据第一行或设置的行 默认为 true
Fun 此函数为每个下拉列表的onchange选择事件触发接口函数
Select 为已经选择的属性 默认为""
Run 为运行此类别
