navigator.cookieEnabled returns a Boolean value that indicates whether cookies are enabled or not. The property is read-only.
Syntax
var cookieEnabled = navigator.cookieEnabled;
cookieEnabledis a Boolean:trueorfalse.
Note: When the browser is configured to block third-party cookies, and
navigator.cookieEnabled is invoked inside a third-party iframe, it returns true in Safari, Edge Spartan and IE (while trying to set a cookie in such scenario would fail). It returns false in Firefox and Chromium-based browsers.Note: Web browsers may prevent writing certain cookies in certain scenarios. For example, Chrome 80+ does not allow creating cookies with
SameSite=None attribute, unless they are created over HTTPS and with Secure attribute.Example
if (!navigator.cookieEnabled) {
// The browser does not support or is blocking cookies from being set.
}
