javascript 通過(guò)封裝div方式彈出div窗體

更新時(shí)間：2009年10月29日 23:05:46 作者：

廢話少說(shuō)，此js對(duì)象是通過(guò)封裝頁(yè)面上的div，將其彈出，可以彈出多個(gè)，參考了一些高人代碼，達(dá)到我要的效果。先看看效果圖。配合一css就可以很好看了。

圖1（彈出一個(gè)div）

圖2（彈出多個(gè)）
構(gòu)造函數(shù)：

 
var DivWindow= function(popup/*最外層div id*/,popup_drag/*拖動(dòng)div id*/,popup_exit/*退出按鈕id*/ ,exitButton/*觸發(fā)服務(wù)器端退出按鈕id*/,varwidth,varheight,zindex){ 
this.popup =popup ; 
this.height =varheight ; //窗口高度,并沒(méi)用來(lái)設(shè)置窗口高度寬度，用來(lái)定位在屏幕的位置 
this.width =varwidth ; //窗口寬度 
this.popup_exit=popup_exit; 
this.exitButton=exitButton; 
this.zindex=zindex; 
this.init = function(){ //初始化窗口 
this.popupShow(); 
this.startDrag(); //設(shè)置拖動(dòng) 
this.setCommond(); //設(shè)置關(guān)閉 
DivWindow.ArrayW.push(document.getElementById(this.popup)); //存儲(chǔ)窗口到數(shù)組 
};this.init(); 
}; 

調(diào)用：

復(fù)制代碼代碼如下:

 
<input type="button" id="show" onclick="javascript:new DivWindow('popup','popup_drag','popup_exit','exitButton','500','700',4);" value='觸發(fā)彈出詳細(xì)基本資料DIV' /> 

有的地方可能大家覺(jué)得有點(diǎn)奇怪，不要問(wèn)我問(wèn)什么，因?yàn)槲矣羞@個(gè)需要，有時(shí)間再修改一下遮罩效果。更詳細(xì)代碼請(qǐng)見(jiàn)下載
