In Angular js How can i clear LocalStorage values when browser closed not browser tab closed.

Hi

Try
localStorage.removeItem(key);

where i need to call that one.because in browser close event or in tab close event

Hi

You can make use of the beforeunload event in JavaScript.

window.onbeforeunload = function() {
  localStorage.removeItem(key);
  return '';
};

But That above method will work work when browser closed event and tab closed tab as well.But my point is when i closed tab my local storage value i did not want to clear.only when i close browser close then it need to work like gmail

I think you're addressing the issue in the wrong way.
You cannot rely on the window events to do this because if the browser crashes, or whatever happens that makes those events no to be triggered, you'll end up with the same problem.

What you need to do is to be able to identify that the application is starting, and if the localCache is present, discard/refresh it.
You're even using AngularJS, so if you have a Single-Page App, whenever the Angular app loads you can clean the LocalStorage. Just note that this will also happen if the user does Ctrl+F5.

$(window).unload(function(){
 localStorage.removeItem(key);
});

above one working fine.from my site i am navigating to other site then click back button Then my local storage is clearing but that is not happend.when i am click back to my site that logged in need to stay.
