CookieStore: change event

Secure context: This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.

A change event is fired at a CookieStore object when a change is made to any cookie.

Syntax

Use the event name in methods like addEventListener(), or set an event handler property.

cookieStore.addEventListener('change', event => { })

cookieStore.onchange = event => { }

Examples

To be informed when a cookie has changed, you can add a handler to the cookieStore instance using addEventListener(), like this:

cookieStore.addEventListener('change', function(event) {
  console.log('1 change event');
});

Alternatively, you can use the CookieStore.onchange event handler property to establish a handler for the change event:

cookieStore.onchange = function(event) {
    console.log('1 change event');
};
