jquery - 我们如何从 web.config 中使用 jquery 读取或获取 session 超时，以便我们可以在 mvc 中处理 session 过期

Question

如何通过ajax调用从Web配置获取Session Value

我尝试了以下代码

<script language="javascript" type="text/javascript">
       var sessionTimeoutWarning = 
    "<%= System.Configuration.ConfigurationSettings.AppSettings
    ["SessionWarning"].ToString()%>";
        var sessionTimeout = "<%= Session.Timeout %>";

        var sTimeout = parseInt(sessionTimeoutWarning) * 60 * 1000;
        setTimeout('SessionWarning()', sTimeout);

        function SessionWarning() {
var message = "Your session will expire in another " + 
    (parseInt(sessionTimeout) - parseInt(sessionTimeoutWarning)) + 
    " mins! Please Save the data before the session expires";
alert(message);
        }
</script>

实际上你是在MVC中这样做的；您可能需要使用 "@" 语法。请尝试一下，它可能会有所帮助。

 <script language="javascript" type="text/javascript">
     var sessionTimeoutWarning =    @System.Configuration.ConfigurationSettings.AppSettings["SessionWarning"].ToString();
     var sessionTimeout = @Session.Timeout;    
     var sTimeout = parseInt(sessionTimeoutWarning) * 60 * 1000;
        setTimeout('SessionWarning()', sTimeout);

   function SessionWarning() {
     var message = "Your session will expire in another " + (parseInt(sessionTimeout) - parseInt(sessionTimeoutWarning)) + 
                   " mins! Please Save the data before the session expires";
     alert(message);
   }
</script>
