我不打算使用你的代码...但这应该有助于集中精力。您可以做的第一件事就是“触发”点击事件以立即切换课程。您可以做的另一件事是默认情况下将CSS类'menu-open'放在正文上 - 并从那里切换。您也可以使用JS添加该类。

  

如何在页面加载中进行侧面导航显示？我还是想   能够切换。

// using some jQuery
var $body = $('body');
var $menuToggle = $('[rel="menu-toggle"]');

$menuToggle.on('click', function() {
  $body.toggleClass('menu-open');
}).trigger('click'); 
// trigger a click to start (on load or whatever)

// or not as a chained method like this:
// $menuToggle.trigger('click');

.sidebar {
  background: gray;
  padding: 1rem;
}

body.menu-open .sidebar {
  background: red;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<button class='menu-toggle' rel='menu-toggle'>☰</button>

<aside class='sidebar'>sidebar</aside>

如何在页面加载中进行侧面导航显示？我仍然希望能够切换。

• 首先，我建议您从该html结构中取出切换按钮，因此它不会与侧边栏隐藏，因此无法在关闭后重新切换它。
• 一旦切换出现并始终存在，请根据您的需要进行定位，在这种情况下，由于.pull-right类，它位于右侧。
• 在document.ready()上切换侧边栏，以便在文档加载完毕时显示为打开状态。

$(document).ready(function() {
  //toggle sidebar on document ready
  $("#wrapper").toggleClass("toggled");
});

//Toggle On/Off
$("#menu-toggle").on("click", function(e) {
  e.preventDefault();
  $("#wrapper").toggleClass("toggled");
});

body {
  overflow-x: hidden;
}

#wrapper {

  -webkit-transition: all 0.5s ease;
  -moz-transition: all 0.5s ease;

}

#wrapper.toggled {
