图1（弹出一个div）

图2（弹出多个）
构造函数：

代码如下:

 
var DivWindow= function(popup/*最外层div id*/,popup_drag/*拖动div id*/,popup_exit/*退出按钮id*/ ,exitButton/*触发服务器端退出按钮id*/,varwidth,varheight,zindex){ 
this.popup =popup ; 
this.height =varheight ; //窗口高度,并没用来设置窗口高度宽度，用来定位在屏幕的位置 
this.width =varwidth ; //窗口宽度 
this.popup_exit=popup_exit; 
this.exitButton=exitButton; 
this.zindex=zindex; 
this.init = function(){ //初始化窗口 
this.popupShow(); 
this.startDrag(); //设置拖动 
this.setCommond(); //设置关闭 
DivWindow.ArrayW.push(document.getElementById(this.popup)); //存储窗口到数组 
};this.init(); 
}; 

调用：

代码如下:

有的地方可能大家觉得有点奇怪，不要问我问什么，因为我有这个需要，有时间再修改一下遮罩效果。更详细代码请见下载
