ha mo, Colin Fraser, John Malechek,

If you go to this site:
http://www.math.grin.edu/~rebelsky/Tutorials/JavaScript/EdMedia97/query.html
you will find a better answer to this question than what you may
otherwise get.
After that, you might want to look at this code:
Get Query String variables in JavaScript
Author: Pete Freitag
Category: JavaScript Use Java Script to get access to the query string
<script>
function getQueryVariable(variable) {
  var query = window.location.search.substring(1);
  var vars = query.split("&");
  for (var i=0;i<vars.length;i++) {
    var pair = vars[i].split("=");
    if (pair[0] == variable) {
      return pair[1];
    }
  } 
  alert('Query Variable ' + variable + ' not found');
}
</script>
Now make a request to page.html?x=Hello
<script>
  alert( getQueryVariable("x") );
</script>
