DOM-based routing based on WordPress body_class()

main.js

// http://paulirish.com/2009/markup-based-unobtrusive-comprehensive-dom-ready-execution/
// Modified to only fire on body class (not body class + ID, working off strictly WordPress body_class)

  // all pages
  common: {
    init: function(){

      // $('a').click(function() {
      //   alert('Hello world!');
      // });

    },
    finalize: function(){ }
  },
  // Home page
  home: {
    init: function(){

      // $('a').click(function() {
      //   alert('Hello world!');
      // })

    }
  },
}

UTIL = {
  fire : function(func,funcname, args){
    var namespace = Roots;  // indicate your obj literal namespace here
    funcname = (funcname === undefined) ? 'init' : funcname;
    if (func !== '' && namespace[func] && typeof namespace[func][funcname] == 'function'){
      namespace[func][funcname](args);
    }
  },
  loadEvents : function(){

    // hit up common first.
    UTIL.fire('common');

    // do all the classes too.
    $.each(document.body.className.split(/\s+/),function(i,classnm){

// kick it all off here
$(document).ready(UTIL.loadEvents);
