这个是网上随便摘的一个例子，是不是感觉很多也很难看懂呢，下面我给大家说一种新方法，保证好看好使。
<script language="JavaScript" type="text/JavaScript">
<!-- Copyright fenggang at 2007/3/23
var w=null;
function MM_openBrWindow(theURL,winName,features) { //v2.0
if(w!=undefined&&isOpen()){
w.close();
}
w=window.open("",winName,features);
w.location.replace(theURL);
}
function isOpen()
{
try
{
w.document;
return true;
}
catch(ex)
{}
return false;
}
//-->
</script>
这个MM_openBrWindow（）函数名是在Dreamweaver中常用的弹出窗口函数名，将这段代码放进页面里
然后再做弹出窗口就只能探出一个窗口了，以上是精髓部分，下面是完整的一个测试页的代码，试试看吧。
