Cindy_Lee 实现的遮罩层的增强版本,增加了增加拖拽,浏览器窗口缩放时遮罩层自动缩放等功能

代码如下所示,代码已经被我重构.... 写的不好,请见谅...

config_VB2005XU.js

// JavaScript Document
var login_VB2005XU = {
	//组件标题
	title:"管理员登录",
	//组件的宽度
	width:300,
	//组件的高度
	height:190, 
	//组件里面的内容
	templete:"<form action='' method='get' class='formClass' id='login'>"+  
	"<table>"+		
		"<tr>"+        
			"<td width='30%'><label class='lab'>账号：</label></td>"+
