用showModalDialog来打开页面
在网上大部分用的都是window.open来打开窗口，但你知不知道还有另一种方法？试试用showModalDialog函数，在本个例子一共用到三个文件，文件的内容如下:[想看看效果请点这里]

First HTML(test.html) :
<html>
<head>
<title>Welcome!</title>
</head>

<body>
<a onclick=ppup1()>点这里</a>
</body>

<script language='javascript'>
function ppup1(){
y=window.showModalDialog("testpp1.html","Dialog Arguments Value","dialogHeight: 100px; dialogWidth: 400px; dialogTop: 400px; dialogLeft: 300px; center: no; help: no");
}
</script>

</html>


Second HTML(testpp1.html) :

<html>
<head>
<title>Pop Up1</title>
</head>
<body>
<a onclick=ppup2() >看见我了吗？试试再点我一下!</a>
<script language='jscript'>
function ppup2(){
y=window.showModalDialog("testpp2.html","Dialog Arguments Value","dialogHeight: 100px; dialogWidth: 400px; dialogTop: 200px; dialogLeft: 300px; center: no; help: no");
}
</script>
</body>
</html>


Third HTML(testpp2.html):

<html>
<head>
<title>Popup2</title>
</head>

<body onunload=window.returnValue="Returning"> I am in the second popup
</body>

</html>

相信showModalDialog这个函数的参数你一定看得懂，这里我就不再解析了。:)
