【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 <input type="hidden" name="ClassId" id="ClassId" />

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

var SelectClass = XiaoFeng.SelectClass = function(){

this.Name = "";

this.Source = new Object();

this.FirstOption = [["==请选择==","0"]];

this.SelectFirst = true;

this.Select = "";

this.Fun = function(e){return;}

this.Run = function(){
