CookieChangeEvent.deleted

Secure context

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

The deleted read-only property of the CookieChangeEvent interface returns an array of the cookies that have been deleted by the given CookieChangeEvent instance.

Syntax

var array = CookieChangeEvent.deleted;

Value

An array of objects containing the deleted cookie(s). Each object contains the following properties:

name

value
A USVString containing the value of the cookie.
domain
A USVString containing the domain of the cookie.
path
A USVString containing the path of the cookie.
expires
A DOMTimeStamp containing the expiration date of the cookie.
secure
A boolean indicating whether the cookie is from a site with a secure context (HTTPS rather than HTTP).
sameSite
One of the following SameSite values:
"strict"
Cookies will only be sent in a first-party context and not be sent with requests initiated by third party websites.
"lax"
Cookies are not sent on normal cross-site subrequests (for example to load images or frames into a third party site), but are sent when a user is navigating within the origin site (i.e. when following a link).
"none"
Cookies will be sent in all contexts.

Note

For more information on SameSite cookies see SameSite cookies explained.

Examples

In this example when the cookie is deleted the event listener logs the first item in the CookieChangeEvent.deleted property to the console. It contains an object representing the cookie that has just been deleted.

cookieStore.addEventListener('change', (event) => {
  console.log(event.deleted[0]);
});
