代碼如下:
<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1" runat="server">
    <title></title>
    <style type="text/css">
    #middle{ top:0; left:0;background-color:#fff; position:absolute; z-index:2; filter:alpha(opacity=60); display:none;}
    #showTree{ width:300px; height:200px; position:fixed; z-index:2; display:none; border:1px solid red;}
    </style>
    <script type="text/javascript">
        function ShowDIv() {
            var txt = document.getElementById("txt");
            txt.blur();
            var divmid = document.getElementById("middle");
            divmid.style.display = "block";
            divmid.style.width = "100%";
            divmid.style.height = "100%";
            var divshow = document.getElementById("showTree");
            divshow.style.display = "block";
            divshow.style.left = txt.offsetLeft;
            divshow.style.top = txt.offsetTop;
            return false;
        }
        function CloseDiv() {
            var divmid = document.getElementById("middle");
            divmid.style.display = "none";
            var divshow = document.getElementById("showTree");
            divshow.style.display = "none";
            return false;
        }
        function TreeViewClick() {
            if (event.srcElement.innerText == "" || event.srcElement.length <= 0 || event.srcElement.nameProp == undefined) {
                return true;
            }
            var id = event.srcElement.id;
            var a = document.getElementById(id);
