Question

我希望使用bootstrap 3框架和侧栏菜单切换一个全面而简单的问题...当我的网站启动时，侧边栏菜单打开，然后我可以在页面切换后关闭加载...但我想知道如何反转这一点，以便在首次加载页面时关闭侧边栏菜单？下面是我正在使用的JS框架，如果需要更多的代码来理解这个问题，我很乐意提供它，但是认为这可能在bootstrap框架中是通用的...提前感谢！这是起始模板代码和链接...... http://startbootstrap.com/template-overviews/simple-sidebar/

附加到＃menu-toggle的点击事件上的jQuery是打开和关闭菜单的神奇之处。此处理程序只是将切换的类添加或删除到页面上具有包装ID的元素。

要在加载页面时关闭菜单，只需将切换的类添加到标记中的包装div ：

<body>
    <div id="wrapper" class="toggled">

        <!-- ...the rest of your markup here -->

    </div>
</body>
