【無限級(jí)下拉列表】
[2009-06-13]
在要放置下拉列表的地方放置一控件，一般為隱藏域 <input type="hidden" name="ClassId" id="ClassId" />
以XML為數(shù)據(jù)源可以用直接調(diào)用 XML 形式
var XMLDOM = LoadXml("CreateXML.ashx?RootId=15&sd=101");
Root = XMLDOM.documentElement;
也可以用Ajax調(diào)出數(shù)據(jù)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 = [["==請(qǐng)選擇==","0"]];
ClassSelect.SelectFirst = true;
ClassSelect.Fun = function(e){}
ClassSelect.Select = "101";
ClassSelect.Run();

參數(shù)說明：Source 為本下拉列表數(shù)據(jù)源 為 XMLDOM
Name 為隱藏控件ID  一般為隱藏域
FirstOption 為下拉列表第一行顯示的文字，如果想給每個(gè)都有不同的可以設(shè)置多個(gè) 例如[["==請(qǐng)選擇所在的省份==","0"],["==請(qǐng)選擇所在的市份==","0"],["==請(qǐng)選擇所在的縣份==","0"]]   如果 FirstOption = "" 或 FirstOption = [] 則不顯示這些文字  默認(rèn) 為[["==請(qǐng)選擇==",""]]
SelectFirst 為是加載完后是否顯示要設(shè)置的文字 true 為顯不 false 為顯示數(shù)據(jù)第一行或設(shè)置的行 默認(rèn)為 true
Fun 此函數(shù)為每個(gè)下拉列表的onchange選擇事件觸發(fā)接口函數(shù)
Select 為已經(jīng)選擇的屬性 默認(rèn)為""
Run 為運(yùn)行此類別
