I am using this JavaScript Code, but it will return only cookies of a particular page. I want to clean all the cookies of Browser

function deleteAllCookies() {
    var cookies = document.cookie.split(";");
    for (var i = 0; i < cookies.length; i++) {
        var cookie = cookies[i];
        var eqPos = cookie.indexOf("=");
        var name = eqPos > -1 ? cookie.substr(0, eqPos) : cookie;
        document.cookie = name + "=;expires=Thu, 01 Jan 1970 00:00:00 GMT";
    }
};

• You can only remove cookies created by JavaScript - if a cookie was create by the server, then you cannot remove it through JavaScript.you need to know name, path and domain of a cookie then only you can reliably delete the cookie – Arunprasanth K V Commented Mar 2, 2015 at 7:27

• I think what you are trying to do is accessing cross domain cookie.Which is not possible due to security reason. How ever I will look forward to see the answer of this. – Abhisek Malakar Commented Mar 2, 2015 at 7:37

You cannot delete cookies via Javascript that e from other domains than the page you are currently on. This is a browser security feature. And, if a cookie is marked for a particular path, you can only access it from a page on that particular path (even from the same domain).

And, for cookies that are marked HttpOnly (e.g. server-side access only cookies), you can't even delete those for your own domain via javascript.

The only way to clear all cookies is for you (the user) to use the browser's user interface to delete the cookies or to configure your browser to automatically clear cookies when you close the browser.
