Checking for GET variables on end of URL

[londrum]

Hello. i've got a little function which is only supposed to run on pages with a specific GET variable. So i've got the following line in it, which works okay

if(location.href=='http://www.example.com/dir/page.php?var=1')

the problem is, whenever an extra GET variable is added to the end, it no longer recognises that the URL is a match.

so

http://www.example.com/dir/page.php?var=1

matches, but

http://www.example.com/dir/page.php?var=1&sid=1

doesn't.

does anyone know a way of changing the code so it checks against the URL and first GET variable, plus any number of random GET variables after it?

thanks!

A better way to solve this problem would be to not use javascript at all. Call a function to check the value of var on the pages you need it checked.

This little bit of code allows you to access the query string parameters much like you would in PHP:

(function () {
var $_GET = (function () {
  var a, i, o = (window.location.search.substring(1)).split('&');
  for (i in o) {
    a = o[i].split('=');
    o[a[0]] = a[1];
  }
  return o;
})();
// Now the GET querystring values are accessible via $_GET['key']
// for example, given querystring ?name=Fotiman&var=1&foo=bar
// if ($_GET['var'] == 1) {
//   dosomething
// }
if($_GET['var'] == 1) {
  alert('success');
}
else {
  alert('no luck');
}
})();
