If you are using jQuery cookie, you might want to try just setting the cookie to null, like this:

$.cookie("name", null);

There was a similar question about it found here: jquery, delete cookies .

Note: when deleting a cookie, you must pass the exact same path, domain and secure options that were used to set the cookie.

To set the path for a cookie, you could use something like this:

$.cookie("name", null, { path: '/' });

what a name stands for in my situation?

In your case, "name" is whatever your cookie's name is. :)

I put a link to jQuery cookie (github.com/carhartl/jquery-cookie) in the answer, as well, just in case you need to get the jquery.cookie.js file to make this work!

i modify the question.i use cookies like this.Again i am confusing what is the name stands for?

It is the name you want to use for your cookie. It's easier to use the jQuery cookie plugin for creating the cookie. To create a cookie, you would just write something like: $.cookie('the_cookie', 'the_value'); In that example, the cookie's name is 'the_cookie'. Then... to delete that cookie... you would just use $.cookie('the_cookie', null);
