具有可折叠边栏的Bootstrap 4 [英] Bootstrap 4 with collapsible sidebar

问题描述

我希望创建一个可折叠的侧边栏，用户可以对其进行切换.经过大量的游戏，我已经实现了，但是现在，它非常丑陋.这是代码:

I wish to create a collapsible sidebar that the user can toggle. After much playing, I have achieved it, but right now, it is very ugly. Here's the code:

<div class="container-fluid">
  <div class="row">
    <nav class="col-md-3 collapse show" id="sidebar">
      <h2>I'm a sidebar</h2>      
    </nav>
    <main class="col-md-9">
      <i class="fa fa-times" data-toggle="collapse" data-target="#sidebar" aria-hidden="true" aria-expanded="false" aria-controls="sidebar"></i>
      <h2>I'm the main content</h2>
    </main>
  </div>
</div>

问题是，折叠是垂直的，然后折叠，内容就不能全宽！

The issue with this is, the collapsing is vertical, and then once collapse, the content doesn't go full width!

推荐答案

有一种简单的方法，您无需使用jQuery.看这个例子:

There is an easy way, you do not need to use jQuery. Look at this example:

<div class="container-fluid">
  <div class="row">
    <nav class="col-md-3 collapse show" id="sidebar">
      <h2>I'm a sidebar</h2>      
    </nav>
    <main class="col-md-9">
      <i class="fa fa-times" data-toggle="collapse" data-target="sidebar" aria-hidden="true" aria-expanded="false" aria-controls="sidebar" onclick="document.getElementById(this.getAttribute('data-target')).style.display = 'none';"></i>
      <h2>I'm the main content</h2>
    </main>
  </div>
</div>

我已经更改了data-target并添加了一个非常简单的onclick.

I've changed data-target and added a very simple onclick.

进一步的改进:

<div class="container-fluid">
  <div class="row d-flex">
    <nav class="col-md-3 collapse show width" id="sidebar">
      <h2>I'm a sidebar</h2>      
    </nav>
    <main class="col-md-9">
      <i class="fa fa-times" data-toggle="collapse" data-target="#sidebar" aria-hidden="true" aria-expanded="false" aria-controls="sidebar" onclick="var that = this; setTimeout(function() {console.log(that.parentNode);that.parentNode.style.flex = 'auto';that.parentNode.style['max-width'] = 'none';}, 2000);"></i>
      <h2>I'm the main content</h2>
    </main>
  </div>
</div>
