Jquery菜单突出显示具有滑块视差的项目

Question

我正在使用视差滑块。在这个视差滑块上，我添加了一个jquery菜单，在选择时突出显示项目。它有效（看看：http://jsfiddle.net/jarod51/26Vgw/3/） 但是当我添加Jquery脚本转到页面幻灯片时，突出显示菜单不再起作用。你知道如何解决这个问题吗？

<div id="cssmenu">
    <ul>
        <li class='active'><a id="testSlide1" href='#'><span>Home</span></a></li>
        <li><a id="testSlide2" href='#'><span>Products</span></a></li>
        <li><a id="testSlide3" href='#'><span>About</span></a></li>
        <li><a id="testSlide4" href='#'><span>Contact</span></a></li>
    </ul>
</div>
<div class="container">
<div id="da-slider" class="da-slider">
            <div class="da-slide">
                <h2>Warm welcome</h2>
