Redirect when cookies are disabled

Question

I need JavaScript code that will detect if a user has cookies disabled in their browser. If they do, they will be redirected to another page. If they have their cookies enabled it just goes straight through as usual.

Answer 1

You can insert a test cookie in browser and call back that cookie again.

Use this library. It contan simple function to identify cookies enabled, create/read or erase cookies.

  <script type="text/javascript">
    /* function to create cookie
    @param name of the cookie
    @param value of the cookie
    @param validity of the cookie
    */
        function createCookie(name, value, days) { 
            var expires;
            if (days) {
                var date = new Date();
                date.setTime(date.getTime() + (days * 24 * 60 * 60 * 1000));
                expires = "; expires=" + date.toGMTString();
            }
            else expires = "";
            document.cookie = name + "=" + value + expires + "; path=/";
        }

        function readCookie(name) {
            var nameEQ = name + "=";
            var ca = document.cookie.split(';');
            for (var i = 0; i < ca.length; i++) {
                var c = ca[i];
                while (c.charAt(0) == ' ') c = c.substring(1, c.length);
                if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length, c.length);
            }
            return null;
        }

        function eraseCookie(name) {
            createCookie(name, "", -1);
        }
    /* 
       This function will create a new cookie and reading the same cookie. 
    */
        function areCookiesEnabled() {
            var r = false;
            createCookie("testing", "Hello", 1); //creating new cookie
            if (readCookie("testing") != null) { //reading previously created cookie
                r = true;
                eraseCookie("testing");
            }
            return r; //true if cookie enabled.
        }
    </script>

and your code must be.

<script>
if(!areCookiesEnabled())
{

//redirect to page
}

</script>
