javascript: pass a variable from one page to another

Hey folks,

Is it possible to pass a javascript variable from one page to another? For example, on page1.htm I want to take the pathname (window.location.pathname) put it into a variable, and pass it to a hidden field contained on a form on page2.htm -- or would that be considered xss?

Thanks!

You could do this through GET when you ask for page 2:

var pathname = encodeURIComponent(window.location.pathname);

window.location = "page2.htm?pathname=" + pathname; //or however you get to your next page

Open in new window

You could then access them on your next page inside an associative array:

And it wouldn't be considered XSS as long as both pages exist on the same domain.

Comment #2 didn't post the code:

function get_array() {
  var vars = [], hash;
  var hashes = window.location.href.slice(window.location.href.indexOf('?') + 1).split('&');
  for(var i = 0; i < hashes.length; i++) {
    hash = hashes[i].split('=');
    vars.push(hash[0]);
    vars[hash[0]] = hash[1];
  }
  return vars;
}

Open in new window

It's not my day. To add to my solution, to use vars:

vars = get_array();
alert(vars["pathname"]);//sample usage

Open in new window

Hi exalkonium,

That's a great solution you've presented, and should work well, though I think we'll also need to access that vars["pathname"] with decodeURIComponent() to strip the encoding if I'm not mistaken. Going to test it out now.

Thanks to you and others!

Ah, you are correct. Sorry, like I said, not my day...seem to be forgetting a lot.
