调用的JS代码：

var Layer=”;
var iLayerMaxNum=1000;
var a;
document.onmouseup=me;
document.onmousemove=ms;
var b;
var c;
function Move(Object,event){
Layer=Object.id;
if(document.all){
   document.getElementById(Layer).setCapture();
   b=event.x-document.getElementById(Layer).style.pixelLeft;
   c=event.y-document.getElementById(Layer).style.pixelTop;
}else if(window.captureEvents){
   window.captureEvents(Event.MOUSEMOVE|Event.MOUSEUP);
   b=event.layerX;
   c=event.layerY+100;
};
if(Layer!="Layer"+a){
   document.getElementById(Layer).style.zIndex=iLayerMaxNum;
   iLayerMaxNum=iLayerMaxNum+1;
}
}
function ms(d){
if(Layer!=”){
   if(document.all){
    document.getElementById(Layer).style.left=event.x-b;
    document.getElementById(Layer).style.top=event.y-c;
   }else if(window.captureEvents){
    document.getElementById(Layer).style.left=(d.clientX-b)+"px";
    document.getElementById(Layer).style.top=(d.clientY-c)+"px";
   }
}
}
function me(d){
if(Layer!=”){
   if(document.all){
    document.getElementById(Layer).releaseCapture();
    Layer=”;
   }else if(window.captureEvents){
    window.captureEvents(Event.MOUSEMOVE|Event.MOUSEUP);
    Layer=”;
   }
}
}
function Close(n){
var e=’Layer’+n;           
document.getElementById(e).style.display=’none’;
}
function Show(n){
var e=’Layer’+n;
document.getElementById(e).style.zIndex =iLayerMaxNum+1;
document.getElementById("aspk").style.display = "block";
document.getElementById("aspk").style.zIndex = iLayerMaxNum;
var size = getPageSize();
document.getElementById("aspk").style.width = size[0];
document.getElementById("aspk").style.height = size[1];
}
function Hide(){
document.getElementById("aspk").style.display = "none";
iLayerMaxNum=iLayerMaxNum+2;
}
function getPageSize(){
var de = document.documentElement;
var w = de.clientWidth;
var h = de.clientHeight;
arrayPageSize = new Array(w,h);
return arrayPageSize;
}

html文件演示代码：

    <div style="display:none;" id="aspk" onclick="Hide();"></div>
    <div>
        <div id="Layer1" style="position:absolute;cursor:move;" onmousedown="Move(this,event)" ondblclick="Show(1)">aaaaaaa</div>
        <div id="Layer2" style="position:absolute;cursor:move;" onmousedown="Move(this,event)" ondblclick="Show(2)">bbbbbbb</div>
        ……
