Javascript: Sending strings to another window

[Acidic]

Here is how you can send data from one page to another:
lets say we want to send the string "Sid is a great man" to page 2, we do this
var string = "Sid is a great man"
document.location = "page2.html?string=" + string

then page two can read the string as follows:

<input type="hidden" name="MyHidden">
<script language="JavaScript">
document.getElementById('MyHiddden').value = document.location
if (document.getElementById('MyHiddden').value.search('string=') != -1)
  {
  var string = document.getElementById('MyHiddden').value.substring(document.getElementById('MyHiddden').value.search('string='),document.getElementById('MyHiddden').value.length)
  alert(string)
  }
</script>

Note. I have NOT tried this code out. tell me if there are errors.
