问题描述
我希望在60秒之前显示会话到期提醒。它工作正常。
如果我们将会话时间设置为2分钟并且警报将在60秒之前到来。但是用户填写表单并且需要5到10分钟意味着用户在我的应用程序上处于活动状态，然后在这种情况下如何重置会话。
我当前代码会话中的
将仅在服务器端重置点击不是客户端活动。
请帮忙。
我尝试过：
I want to show session expiry alert before 60 seconds. It's working fine.
if we have set session time out 2 minutes and alert will come before 60 seconds. But user are fill a form and it will take 5 to 10 minutes means user are active on my application then in this case how to reset session .
in my current code session will be reset only on server side hit not client side activites.
Please help.
What I have tried:
Inside web config--
<sessionState timeout="5"/>
<asp:ScriptManager ID="ScriptManager1" runat="server" EnablePageMethods="true" EnablePartialRendering="true" ScriptMode="Release" AsyncPostBackTimeout="150">
</asp:ScriptManager>
<asp:LinkButton ID="lnkFake" runat="server" />
<asp:ModalPopupExtender ID="mpeTimeout" BehaviorID="mpeTimeout" runat="server" PopupControlID="pnlPopup"
TargetControlID="lnkFake" OkControlID="btnYes" BackgroundCssClass="modalBackground"
OnOkScript="ResetSession()">
</asp:ModalPopupExtender>
<asp:Panel ID="pnlPopup" runat="server" CssClass="modalPopup" Style="display: none">
<div class="header">
Session Expiring!
</div>
<div class="body">
Your Session will expire in <span id="seconds"></span> seconds.<br />
Do you want to reset?
</div>
<div class="btnSection" align="right">
<asp:Button ID="btnYes" runat="server" Text="OK" CssClass="yes" />
</div>
</asp:Panel>

没有办法准确地做到这一点;但是，您可以做的是创建一个启用了Session的WebMethod，并且随时完成客户端活动，您可以使用jQuery的.ajax（）调用来调用此WebMethod，这将重置会话服务器端而无需回发。
然后用JavaScript重置你的计时器。
There is no way to accurate do it; however, what you can do is create a WebMethod that has Session enabled and anytime client-side activities are done you can call this WebMethod using jQuery's .ajax() call which will reset the session server side without having to post back.
And then reset your timer in JavaScript.
