Since you're using jQuery, you could give this cookie plugin a try https://github.com/carhartl/jquery-cookie — elclanrs, Feb 26 '12 at 04:30
@elclanrs there is not any method in java script to delete cookies without function. — 4b0, Feb 26 '12 at 04:41

You can just trigger that function in you button's onclick event..

<script type="text/javascript">
function del_cookie(name)
{
    document.cookie = name + '=; expires=Thu, 01-Jan-70 00:00:01 GMT;';
}
</script>
<INPUT TYPE=BUTTON OnClick="del_cookie('put name of cookie here');" VALUE="Clear Cookie"/>

I wouldn't recomend the way you are implementing the cookie, I think you should use name/value pairs. But for the actual implementation you are using, to clear the cookie, you can use:

document.cookie = '';

Note that this won't work if you start using name/value pairs because it would only add an empty name/value to your existing cookies.

Delete the cookie

And finally, to delete a cookie set its value to null. Note:- Setting it to e.g. an empty string doesn’t remove it; it just clears the value.

$.cookie("example", null);

or

This is a session cookie and will be destroy when user close his/her browser. We can do it like this:

$.cookie("example", "demo", { expires: -1 });
