How to detect that JavaScript and/or Cookies are disabled?

Question

How to detect that JavaScript or Cookies are disabled in the user\'s browser and notify him any help ?

Answer 1

As the cookie detection didn't work in IE 11, I suggest the Modernizr approach:

function areCookiesEnabled() {
    try {
      document.cookie = 'cookietest=1';
      var cookiesEnabled = document.cookie.indexOf('cookietest=') !== -1;
      document.cookie = 'cookietest=1; expires=Thu, 01-Jan-1970 00:00:01 GMT';
      return cookiesEnabled;
    } catch (e) {
      return false;
    }
}
