Clear local storage when user closes window

Question

How do I clear local storage when my website is closed in all the tabs in a browser? means If my user is open my website in multiple tabs, and when user is close browser or close tabs one by one, I need to clear local storage on last tab close event (e.g. on beforeunload event).

Does anybody have idea to do this?

This is how you do it:

window.onbeforeunload = function() {
    localStorage.clear();
}
