How to check session is expired or not and redirect user to login page using javascript
提问by CodeWarrior
I am developing web application using ASP.Net MVC. In my application I am using some many ajax calls through out my application to Get/Post data for some functionality. For some functionality I am showing iframed popup. My issue is that when session is expired in my application I am redirecting user to login page but if user try to access functionality that opens in iframed popup instead of redirecting to login page my popup opens with login page inside it otherwise it's working properly. So what is best way to check session is expired or not and redirecting user to login page from inside of iframed popup. The code for opening iframed popup is as follow:
我正在使用 ASP.Net MVC 开发 Web 应用程序。在我的应用程序中，我在我的应用程序中使用了许多 ajax 调用来获取/发布某些功能的数据。对于某些功能，我正在显示 iframe 弹出窗口。我的问题是，当我的应用程序中的会话过期时，我将用户重定向到登录页面，但是如果用户尝试访问在 iframe 弹出窗口中打开的功能而不是重定向到登录页面，我的弹出窗口将打开并显示登录页面，否则它会正常工作。那么检查会话是否过期并将用户从 iframe 弹出窗口内部重定向到登录页面的最佳方法是什么。打开 iframe 弹出窗口的代码如下：
function ShowPopup(Url, DialogTitle, W, H) {
/* Setting for dialog box */
$("#dialog").dialog({
title: DialogTitle,
autoOpen: false,
modal: true,
resizable: false,
width: W,
height: H,
open: function (ev, ui) {
/* Setting URL to open in iframe */
$('#ContentIframe').attr('src', Url);
}
});
/* Opening dialog box */
$('#dialog').dialog('open');
}

Make as to check session
使作为检查会话
function CheckUserSession(svcUrl) {
var userInSession = false;
$.ajax({
url: Your Url,// It will return true/false based on session
type: 'POST',
dataType: 'json',
contentType: 'application/json; charset=utf-8',
async: false,
success: function (result) {
userInSession = result.userInSession;
}
});
return userInSession;
}
Before calling your code check this
在调用您的代码之前检查这个
if(CheckUserSession() == false){
ShowLogin();
}
else{
//Your code
}

It can be done using following logic...
它可以使用以下逻辑完成...
Write following block of code in your Login Page
在您的登录页面中编写以下代码块
<script type="text/javascript">
window.onload=function()
{
if (window!=window.top)
{
window.top.location = "YourLoginPageURL";
window.close();
}
};
</script>
(window!=window.top) will return true if Login page is opened in IFra
如果在 IFra 中打开登录页面，(window!=window.top) 将返回 true
Hope it helped
