$(document).ready(function () {
var id = "#!" + window.location.href.split("!")[1];
if ($("ul li a[href=" + id + "]").length) {

You need to enclose special characters in quotes when using a attribute based selector.

if ($('ul li a[href="' + id + '"]').length) {

Your version of selector would result

if ($("ul li a[href=#!...]").length) {

The #! will throw unrecognized expression.

My version where the "" escape the characters

if ($('ul li a[href="#!..."]').length) {
