{
14 window.location.href="/ClosePage.aspx"

}

19</head>
20<body onunload="ClosePage()">

23 <asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Button" /></div>
24 </form>
25</body>
26</html>
在ClosePage.cs页面的 Page_Load销毁如下： Session.Abandon(); <%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default2.aspx.cs" Inherits="Default2" %>2

if((window.screenLeft>=10000 && window.screenTop>=10000)||event.altKey)
