How to check if the browser has cookies turned off?

Sample code:

function ff() {
    if (navigator.cookieEnabled) {
        alert('Yay, cookies!');
    } else {
        alert('Bah, no cookies!');
    }
}
document.getElementById("x4265").onclick = ff;

The “navigator.cookieEnabled” is supported by all major browsers.
