What code do I use to check for Cookie?

Hi,

The code I am using only checks cookie name from the URL my browser is on.

How can I check for a cookie name no matter what URL it came from?

For example, if the cookie "popover" comes from "mindreality.com", how can I check for it even if it comes from "ubermanpower.com" or any other URL without being restricted to the URL that my browser is on?

  • You cant with a server side script. That is from website A you can only read cookies that are from website A not from any other website:

    • What I mean is, if the browser (Firefox for e.g.) is already cookied with "popover" from "Ubermanpower.com" but right now it is viewing "MindReality.com", I want my code on "MindReality.com" to be able to check for the cookie "popover" even though it is from "Ubermanpower.com. Keep in mind that the browser is already cookied.

      How do I do that?

      My code is:

      Code:
      function getcookie(cookiename) {
 var cookiestring=""+document.cookie;
 var index1=cookiestring.indexOf(cookiename);
 if (index1==-1 || cookiename=="") return ""; 
 var index2=cookiestring.indexOf(';',index1);
 if (index2==-1) index2=cookiestring.length; 
 return unescape(cookiestring.substring(index1+cookiename.length+1,index2));

function cookiecheck(){
var currentvalue;
var uservalue =1;
var popoverdelay = 0;
if(getcookie('popover') > 0){
currentvalue = getcookie('popover');
if(currentvalue == (uservalue+1))
  • Cookies are presented only for the site the browser is on, and to there. So if a user vists mysite.com, you can't get the cookies for google.com on mysite.com. Javascript is ALSO run from the site and subject to those constraints.
