You can read cookie this way

function readCookie(name) {
var nameEQ = escape(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 unescape(c.substring(nameEQ.length,c.length));
}
return null;
}

Open in new window


Or you can also use JQuery cookie plugin.

Thanks.

GetCookies in a page using javascript

http://www.w3schools.com/js/js_cookies.asp

function getCookie(c_name)
{
var i,x,y,ARRcookies=document.cookie.split(";");
for (i = 0;i < ARRcookies.length;i++)
{
  x=ARRcookies[i].substr(0,ARRcookies[i].indexOf("="));
  y=ARRcookies[i].substr(ARRcookies[i].indexOf("=")+1);
  x=x.replace(/^\s+|\s+$/g,"");
  if (x==c_name)
    {
    return unescape(y);
    }
  }
}
