求一个showModalDialog的例子

参考这个例子http://www.cnblogs.com/jackyrong/archive/2005/06/12/172943.html

主窗口
rt = showModalDialog('child.htm',self,''); //把窗口本身传给child,child里就可以通过它引用任何DOM对象child.htm
win = dialogArguments; //取得父窗口即self或window
win.location.reload()即刷新父窗口
returnValue = "xxx" //传回给主窗口rt的值，可以是对象
主页面：<html>
<head >
    <title>未命名頁面</title>
</head>
<body>
<script type="text/javascript">
function fnOpen(){
   var strReturn = window.showModalDialog("Default9.aspx", true);
   if(strReturn!='')
   {
        alert(strReturn);
        window.location.reload();
   }
}
</script>
<form >
<input TYPE="button" VALUE="Push To Create"  onclick="fnOpen()">
</form>
</body>
</html>
开窗页：<html  >
<head runat="server">
    <title>未命名頁面</title>
    <script type="text/javascript">
    function fnClose()
    {
        window.returnValue = "ssss";
        window.close();
    }
    </script>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <input id="Button1" type="button" value="button" onclick="fnClose()"/></div>
    </form>
</body>
</html>
