<script languate="javascript" type="text/javascript">
	
	//Get the values from the url variable id
	//(getUrlVars Code URL: http://snipplr.com/view/19838/get-url-parameters/)
	function getUrlVars()
	{
		var vars = {};

	//scroll to the specific div, assuming each div is named "div_(number)"
	function scrollToID()

This code assumes a page is populated with divs with ids div_1, div_2, div_3 etc etc etc...

Some quick php to create 200 divs numbered as above:

<?php>".
			 "	DIV ".$i.
			 "</div>";
	}
?>

To test the code, add an id to the url so its something like this (assuming urlVars.php is the name of the page):

urlVars.php?id=80

Play around with the id number to test.

Scroll to specific div using a variable from the URL on page load
