How to destroy cookies on page refresh

问题

Hello I need to destroy javascript cookies on a page refresh. I need to set a new bunch of cookies on every page load which help me render the web page based on user options. Is there a method to destroy cookies on a page refresh??

回答1:

May be you could remove cookies on page unload.

For example, with jQuery:

$(window).unload(function() {
  //Destroy cookies here
});

回答2:

You need to detect the page refresh, have a look at:

Detecting Page Refreshes :: Using JavaScript on Client-Side

Once you know that, you should be able to delete the cookies.
