javascript 面向对象,实现namespace,class,继承，重载 JScript 脚本实现文件下载一般用于下载木马

废话少说，此js对象是通过封装页面上的div，将其弹出，可以弹出多个，参考了一些高人代码，达到我要的效果。先看看效果图。配合一css就可以很好看了。

图1（弹出一个div）

图2（弹出多个）
构造函数：

复制代码代码如下:

 
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：

复制代码代码如下:

 
<input type="button" id="show" onclick="javascript:new DivWindow('popup','popup_drag','popup_exit','exitButton','500','700',4);" value='触发弹出详细基本资料DIV' /> 

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
