//弹出隐藏层
function ShowDiv(show_div,bg_div){

var bgdiv = document.getElementById(bg_div);
bgdiv.style.width = document.body.scrollWidth;

<body>
<input id="Button1" type="button" value="点击弹出层" onclick="ShowDiv('MyDiv','fade')" />
<!--弹出层时背景层DIV-->
<div id="fade" class="black_overlay">
</div>
<div id="MyDiv" class="white_content">
<div style="text-align: right; cursor: default; height: 40px;" id="move">
<span style="font-size: 16px;" onclick="CloseDiv('MyDiv','fade')">关闭</span>
</div>
目前来说，我还是喜欢这个自己改造的弹出层。自己在项目中也用的是这个。

如果需要随意移动弹窗，可以在<script></script>中加入以下代码：
window.onload = function (){
var myDiv = document.getElementById("MyDiv");
var move = document.getElementById("move");
var bDrag = false;
var disX = disY = 0;
move.onmousedown = function (event){
var event = event || window.event;
bDrag = true;
disX = event.clientX - myDiv.offsetLeft;
disY = event.clientY - myDiv.offsetTop;
this.setCapture && this.setCapture();
return false;
};
document.onmousemove = function (event){
if (!bDrag) return;
var event = event || window.event;
var iL = event.clientX - disX;
var iT = event.clientY - disY;
var maxL = document.documentElement.clientWidth - myDiv.offsetWidth;
var maxT = document.documentElement.clientHeight - myDiv.offsetHeight;
iL = iL < 0 ? 0 : iL;
iL = iL > maxL ? maxL : iL;
iT = iT < 0 ? 0 : iT;
iT = iT > maxT ? maxT : iT;
myDiv.style.marginTop = myDiv.style.marginLeft = 0;
myDiv.style.left = iL + "px";
myDiv.style.top = iT + "px";
return false;
};
document.onmouseup = window.onblur = move.onlosecapture = function (){
bDrag = false;
move.releaseCapture && move.releaseCapture();
};
}
