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:
