asp.net 用XML產生放便擴充的自訂樹

資料來源為XML，因此放便擴充。
廢話不多說，直接上代碼（因一些原因，把部分資料修改或精簡了）。

相關JS代碼： 複製代碼 代碼如下:function DoNodes(obj,type)
{
var divId=obj.id+'Nodes';
var qdivObj=$("#"+divId);
if(qdivObj.is(":hidden"))
{
qdivObj.show();
if(type=='menu')
{
$(obj).children("img").attr("src","Images/open-menu.gif");
}
else
{
qdivObj.siblings(".Menus:visible").hide();
}
}
else
{
qdivObj.hide();
if(type=='menu')
{
$(obj).children("img").attr("src","Images/close-menu.gif");
}
}
}
function DoAClick(id)
{
$("#"+id).click();
}
function AlertVip()
{
alert("非常抱歉,此模組只對VIP會員開放!");return false;
}

最後效果

此代碼我覺得易放便擴充，只要稍改動一下代碼就能使用在自己的項目中。
