How to pass javascript/jQuery settings from page to page in rails?

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;"><开发者_C百科/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.

Try passing the params through a hidden field - http://api.rubyonrails.org/classes/ActionView/Helpers/FormHelper.html#method-i-hidden_field

Your persistent storage options are session, database (i.e. a preferences table), and cookie.

If you don't want to use session or cookie, the only other option I see is modify the link URL when that div color changes to add a query string parameter with that color.

There is no need if jQuery or Javascript.

Onto the call of that link you can either store background-color in SESSION or COOKIE
