As rails 3 uses jquery and you are writting code in prototype. That might creating issue here.

So try convert your code in jquery. Your code might look like.

$( document ).ready(function() {
// Run code
});

But consider below and make your changes as per your need

$(window).load(function(){
  // Run code ##It will run the js after the whole page is loaded.
});

$(document).ready(function(){
 // Run code ##It will run the js just after the loading of DOM. 
});
