Alternative for url patterns:

/* for IE */
if (!Array.prototype.indexOf) {
    Array.prototype.indexOf = function(obj, start) {
         for (var i = (start || 0), j = this.length; i < j; i++) {
             if (this[i] === obj) { return i; }
         }
         return -1;
    }
}
(function() {

    var noLoad = false;

    for (var i = 0; i < pages.length; i++) {
