When doing javascript manipulation of what's visible, how does one pass that from page to page (ideally in Rails)?

For example, let's say I have the following simple jQuery code:

<% link_to "Next Page", report_path %>
<div class="clickable-div" style="background-color:#FFFFFF;"></div>
<script>
$('.clickable-div').click(function () {
  var color = $(this).css("background-color", "#000000");
});
</script>

If it's not clear, the code is just supposed to change the color of the div based on whether or not it has been clicked. Regardless, there's also a link on the page that allows someone to go to the reporting page. What's a way to pass the state of the div to the action call?

EDIT

It seems unnecessary to do it in a session - am I wrong? This is just something from one page to the next, I couldn't care less anywhere else on the site.

EDIT 2

To confirm, Rails needs to have access to the action that occurred in Javascript on the previous page.
