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');
};
