javascript - 第一次隐藏切换栏

Question

我有一个切换菜单的代码，当我点击切换时，侧面菜单被隐藏，当我再次点击切换时，它会出现。但我想稍微改变一下，目前第一次加载页面时，默认情况下会出现侧边菜单，当我点击切换时它会消失，我希望第一次加载页面时出现侧边菜单应该隐藏，当我点击切换时它应该出现。谁能告诉我怎么做

<div id="wrapper">
        <div id="sidebar-wrapper">
            <ul class="sidebar-nav">
                <li>
                    <a href="#">Dashboard</a>
                </li>
            </ul>
        </div>

       <a href="#menu-toggle" class="btn btn-default" id="menu-toggle">toggle</a>
   </div>
   <script src="js/jquery-1.11.0.js"></script>

    <!-- Menu Toggle Script -->
    <script>
       $("#menu-toggle").click(function(e) {
            e.preventDefault();
            $("#wrapper").toggleClass("toggled");
        });
    </script>

用于整个切换的 css

#wrapper {
    padding-left: 0;
    -webkit-transition: all 0.5s ease;
    -moz-transition: all 0.5s ease;
    -o-transition: all 0.5s ease;
    transition: all 0.5s ease;
}

#wrapper.toggled {
    padding-left: 250px;
}

#sidebar-wrapper {
    z-index: 1000;
    position: fixed;
    left: 250px;
    width: 0;
    height: 100%;
    margin-left: -250px;
    overflow-y: auto;
    background: #000;
    -webkit-transition: all 0.5s ease;
    -moz-transition: all 0.5s ease;
    -o-transition: all 0.5s ease;
    transition: all 0.5s ease;
}

#wrapper.toggled #sidebar-wrapper {
    width: 250px;
}

#page-content-wrapper {
    width: 100%;
    padding: 15px;
}

#wrapper.toggled #page-content-wrapper {
    position: absolute;
    margin-right: -250px;
}

绑定(bind)后可以触发点击事件:

$("#menu-toggle").click(function(e) {
        e.preventDefault();
        $("#wrapper").toggleClass("toggled");
}).click();  //click triggered....
