delete cookies during page change , page close and page load

Question

i wanted to delete all my cookies in these events.Some says that by setting the cookie expire date to NULL or -1 will work. i tried setting them and close the page and re-open the page again. but the cookie is still there. i have checked the cookie status and it is shown session instead of expire date.

and cookies expired it will automatically delete from client side?or it is visible but unusable?

Answer 1

You can use the .unload event to delete cookies before the browser / page closes.

    $(window).unload(function() {
       $.cookies.del('name_of_your_cookie');
    });

Similarly you can use it with .load event.
