Deleting All Cookies for Current Domain with JavaScript

In JavaScript, deleting all cookies for the current domain involves programmatically removing them from the browser's storage.

How to Delete All Cookies Using JavaScript

To clear all cookies for the current domain, you can use the following JavaScript function:

function deleteAllCookies() {
    document.cookie.split(';').forEach(cookie => {
        const eqPos = cookie.indexOf('=');
        const name = eqPos > -1 ? cookie.substring(0, eqPos) : cookie;
        document.cookie = name + '=;expires=Thu, 01 Jan 1970 00:00:00 GMT';
    });
}

This function iterates through all cookies stored in the document's cookie property, extracting their names and setting them with an expiration date in the past (January 1, 1970), effectively "deleting" them.

Limitations of the Approach

Note that this code has some limitations:

• It cannot delete cookies with the HttpOnly flag set, which prevents JavaScript from accessing them.
• It cannot delete cookies set with a specific Path value and requires matching the Path value used when setting the cookie.
