If you don't mind the user seeing the values, you can put them in
the page's query string and get them from there. A very simplistic
example:

<script type="text/javascript">
function setVars()
{
	// set the query string on a link with the id "a2"
         document.getElementById("a2").href += "?foo=bar";

	// set the query string on self to handle reloads
         if ( window.location.search.length == 0 )
         {
                 window.location.search = "foo=bar";
         }
}
</script>
<body>
<a id="a2" href="another.html">another page</a>
</body>

Only moderately tested, YMMV, etc., etc. OVerall, I'd probably just
use a cookie to persist such preferences, though :-)
