描述：
1:一个页面有三层z-index[1,2,3]
div1:有个按钮OpenDiv，当点击时，弹出div2[遮罩层zindex=2]和一个动态createElement("table")[zindex=3]
2:table里有一个按钮[type=button],点击这个按钮div2和table都被remove掉
//删除遮蔽层 EnvelopLayer
var layerBeta=document.getElementById("EnvelopLayer");
layerBeta.parentNode.removeChild(layerBeta);
//删除table
var divid=2;
var tbl=document.getElementById("Window_"+divid);
tbl.parentNode.removeChild(tbl);
3:这个页面是aspx页面
问题：这个按钮点2次才起作用。不知道为什么？
如果是html页面，点击一次就会起作用。
可为什么aspx页面就2次呢？

部分js代码
建立遮罩层
function createEnvelopLayer()
{
var h=document.documentElement.clientHeight;
var w=document.documentElement.clientWidth;
var div=document.createElement("<div id='EnvelopLayer' style='position:absolute;visibility:visible;background:#000;filter:alpha(opacity=20);z-index:500;left:0;top:0;width:"+w+"px;height:"+h+"px;color:#fff'></div>");
div.id="EnvelopLayer";
document.body.appendChild(div);
}
//create table
this.oTable = document.createElement("table");
this.oTable.id = "Window_" + this.id;
this.oTable.style.width = this.width + "px";
//this.oTable.style.height = "100px";
//set zIndex
this.oTable.style.zIndex="1000"
//this.oTable.style.width = "100%";
//this.oTable.style.height = document.body.scrollHeight
//this.oTable.style.border = "1px solid #C2C3BD";
this.oTable.cellSpacing = 0;
//this.oTable.cellPadding = 2;
this.oTable.cellPadding = 0;
//this.oTable.border = 0;
//this.oTable.style.backgroundColor = "#FFFFFF";
// determine the windows position when first open
this.oTable.style.position = "absolute";
this.oTable.style.left = this.x + "px";
this.oTable.style.top = this.y + "px";
// link from the table to the JSWindow object
this.oTable.jsWindow = this;
// if the table is clicked anywhere, show the table in front of other open windows
this.oTable.onmousedown = JSWindow.prototype.onBringToFront;
this.oTable.className="tanchu";
this.oContentTD.innerHTML = document.all["Div" + this.id].innerHTML;
