我有以下 session 超时 jquery 语句:
<script type='text/javascript' src='http://ajax.googleapis.com/ajax/libs/jquery/1.6.4/jquery.min.js'></script>
<script type="text/javascript">
idleTime = 0;
$(document).ready(function () {
// Inkrementerer every minute
var idleInterval = setInterval(timerIncrement, 1000); // 1 minute
// reset the counter when mouse moved or key pressed
$(this).mousemove(function (e) {
idleTime = 0;
});
$(this).keypress(function (e) {
idleTime = 0;
});
});
function timerIncrement() {
document.getElementById("<%= lblSessionTime.ClientID %>").innerText = idleTime;
idleTime = idleTime + 1;
if (idleTime > 19) { // 20 minutes
// Send status to Database
}
}
</script>
当空闲时间超过 20 分钟时，我想向 MySQL 数据库发送一个状态，该页面现在处于脱机状态。我无法弄清楚如何使用 JQuery 来做到这一点。有什么想法吗？

最佳答案
为什么不调用 C# WebMethod？这将是一种 AJAX 方法，需要使用 ScriptManager..
ASPX:确保在您的 FORM 标记内添加一个 ScriptManager 对象并设置 EnablePageMethods = true
<form id="form1" runat="server">
<asp:ScriptManager ID="ScriptManager1" runat="server" EnablePageMethods="true">
</asp:ScriptManager>
/* REST OF YOUR HTML */
</form>
JavaScript:您将需要修改您的timerIncrement 函数并调用C# WebMethod
function timerIncrement() {
document.getElementById("<%= lblSessionTime.ClientID %>").innerText = idleTime;
idleTime = idleTime + 1;
if (idleTime > 19) { // 20 minutes
// Call C# WebMethod to send status to Database
PageMethods.SendStatustoDB();
}
}
C# 代码隐藏:您需要引用以下内容:
using System.Web.Services;
然后添加以下方法，并确保将 [WebMethod] 放在方法声明之前:
[WebMethod]
public static void SendStatustoDB()
{
// code to connect to DB and set status!
}
关于jquery - 当 session 超时到期时，将状态发送到数据库。 ASP.Net 和 Jquery，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/22717339/
