Call a method on browser closing
I am facing an issue in my application when a user directly clicked on browser close [X] button. Browser can be IE, Chrome, Mozilla, Firefox and many more.
What I want to do: 1. as soon as user hits [X] button of browser, n开发者_如何学Pythoneed to set their status as logged off in database for which we have a method in Login.aspx file which is within the master page. 2. We do not have any Logoff feature in the application
I will be thankful if anyone suggests a solution to call the method which sets the user status as logged off from master page.
Thanks in advance.
This is not possible due to the nature of http connections and the web in general. Simply have a timeout (eg. 10 minutes) after which a user gets logged out automatically.
Javascript has an onunload function, so you could do:
<body onUnload="doFunction()">
However this, and other methods are going to be unreliable (I'm not sure in which specific instances it is fired) as it would be a security concern allowing websites to have access to perform many functions on browser onunload.
The best solution would be to have cookies/sessions automatically time out, and also to educate users to logout if the system is sensitive.
If you are using jQuery you could work with
$(window).unload( function () {
$.ajax({ **your params** });
} );
But I have to agree with Tom Gullen here - your sessions should timeout eventually.
