原創

全是套路

該例子實現的功能為:用戶申請加入活動,先通過網頁對話登陸,登陸成功後顯示活動詳細信息,用戶提交申請,提交成功返回true,否則返回False.

具體代碼如下:

treeTest.aspx

<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
    <title>Untitled Page</title>
    <script type="text/javascript">
    function Jump()
    {
       var str=window.showModalDialog("Default2.aspx","aaa","dialogHeight:600px;dialogWidth:750px;center:yes;help:no;resizable:no;status:no;");
       alert(str);
    }
    </script>
</head>
<body>
    <form id="form1" runat="server">
    <div id="div1">
        <asp:Button ID="Button1" runat="server" Text="申請加入活動" OnClientClick="return Jump();"/>
        </div>
    </form>
</body>
</html>

2008-12-8日補充:最近發現一種更簡潔,更有效的方法來解決此類問題.就是在HTML頭文件中加代碼

<base target="_self"/>.還不清楚這兩種做法有什麼差異,後面清楚了再來補充.
