By using an href attribute inside an anchor tag you can scroll the page to a specific element using a #
in front of the elements id name.
Also, here is some jQuery/JS that will accomplish putting variables into a div.
<html>
<body>
Click <a href="#myContent">here</a> to scroll to the myContent section.
<div id="myContent">
...
</div>
<script>
var myClassName = "foo";
$(function() {
$("#myContent").addClass(myClassName);
});
</script>
</body>
