但我无法做到这一点，任何人都可以帮助我，请

Answer 1

您还需要在添加类时（{em>在我的代码:hover 中）启用.active样式，并使用javascript应用该类

所以

  &:hover{
    color: $yellow;
  }

会变成

  &:hover,
  &.active{
    color: $yellow;
  }

（所有相关:hover州的等）

并且将使用此代码切换类

$('button').on('click',function(){
  $(this).toggleClass('active')
});

好吧所以我更多地了解它并理解你所说的简单从这个codepen中获取代码，我所做的只是在悬停时删除，一切都很好 http://codepen.io/hobolandjacob/pen/MyGVpo

好吧，我添加了一个表并修复了所有内容，只需用按钮包围你想要效果的所有内容，它应该可以工作我删除其他css类，如SPIN和东西只是为了保持它干净并专注于让它工作{{3 }}

<button class="draw">
  <table>
    <tr>
      <td>Example</td>
      <td>Example</td> 
      <td>Example</td>
    </tr>
    <tr>
      <td>This</td>
      <td>Is</td> 
      <td>TEST</td>
    </tr>
  </table>
</button>
