In my Application i want to detect Browser or Tab close event and then for this event would like to submit form for logout function and clear user session.
I have tried window.onbeforeunload event but it is fire for all even i click link or refresh page.
Any one can please help me.
There is no specific API to achieve what you want.
What you can do is the following:
In this way after a (relatively) small delay if the frontend is not running you end up with an expired session/access token and the user is effectively logged out.
Cons of this approach: if the user has a small window of connectivity problems their session will expire. If your system is a mobile application this might make your App very frustrating to use in various circumstances. Might not be a big problem if your use case is access from workstations.
You cannot detect a browser/tab close event natively in JavaScript. When the user closes a tab, all the script running on the page effectively ceases executing and no javascript code can run after that.
