Question

I am trying to delete a the value cookie that I created after a certain interval. Lets say after 10 second I want the cookie gone

function fullday()
{
    document.getElementById("res").innerHTML="1 day";
    document.cookie="day="+1;
    document.cookie.setMaxAge(0);
}

This is the code above. I’m coding in PHP right now and then when I try to destroy cookie from PHP it works fine, however I need to pass the cookie’s value in javascript so now im stuck with it and cannot destroy it.

In order to delete a cookie you need to set the expiry date to something in the past. A function that does this would be for example:

var delete_cookie = function(name) {
    document.cookie = name + '=;expires=Thu, 01 Jan 1970 00:00:01 GMT;';
};

Then to delete a cookie named “cookie” just do.

delete_cookie('cookie');
