The simplest way is to not pass the data to JavaScript, but rather get
the value from the DOM using JavaScript/jQuery. This is accomplished by
using HTML5 data attributes.

Say you have a Ruby variable x:

HTML
------------
<div id="my_div" data-x="my_ruby_value">My content</div>

JavaScript
------------
function myFunction() {
var x = $('#my_div').data("x");
// Do something with x
}

Ryan Bates did a Railscasts episode on a few techniques to keep your
JavaScript unobtrusive and yet still have access to your Ruby data:
