* 創(chuàng)建彈出div窗口。
1、接口說明：DivWindow(id,title,width,height,content) 構(gòu)造函數(shù)，創(chuàng)建一個彈出窗口對象
參數(shù)：id 彈出窗口id；
title：彈出窗口標(biāo)題名稱；
width：彈出窗口寬度
height：彈出窗口高度
content： 彈出窗口顯示內(nèi)容

2、接口說明： closeDivWindow(id) 關(guān)閉窗口
參數(shù)： id 彈出窗口id

3、接口說明：setPopupTopTitleFontColor(PopupTopTitleFontColor) 設(shè)置彈出窗口標(biāo)題字體顏色
參數(shù)：

4、接口說明：setPopupTopBgColor(tBgColor) 設(shè)置彈出窗口標(biāo)題背景顏色

5、接口說明：setPopupColor(borderColor,bgColor,tFontColor,cBgColor,fColor) 設(shè)置彈出窗口風(fēng)格,包括標(biāo)題欄的背景，彈出窗口邊框顏色，內(nèi)容窗體背景顏色，內(nèi)容窗體字體顏色

6、接口說明：open()

使用方法：
var a = new DivWindow("1","窗口測試",580,400,"Welcome to visited my personal website:<br><a href=http://www.qqview.com target=_blank>http://www.qqview.com</a><br><ahref=http://www ... qqview.com</a><br><br>thx!!!=)..."L);
a.setPopupTopBgColor("black","blue","white","white","black");
a.open();

生成的html：
<div id='"window"+id'></div> 控制背景的div，使背景逐漸變暗
<div id='"windowTopBg"+id'>
<div id='"windowTop"+id'>
<span id='"windowTopTitle"+id'>title</span>
<span id='"windowTopOperate"+id'>maxORmin</span>
<span id='"windowTopClose"+id'>close</span>
</div>
<div id='"windowContent"+id'>content</div>
</div>
