javascript - 如何在两个链接之间使用 toggleClass 方法

Question

我正在开发一个登录和注册表单，我必须在其中从登录链接切换到注册页面。因此，对于用户来说，为了知道他在哪个链接中，我想在他单击该链接时为该特定链接着色。所以我为它使用了 toggleClass 但它不能正常工作。我在下面发布了我所做的代码。

这是 jsfiddle link

HTML

 <div class="container">
  <div class="frame">
  <div class="nav">
  <ul>
  <li><a class="btn">Sign in</a></li>
  <li><a class="btn1">Sign up </a></li>
  </ul>
    </div>


  </div></div>

你的代码可以总结为这3行代码

1. 从所有元素中删除 toggle 类

2. 给被点击的元素添加切换类

   $(".btn").click(function(){
    $(".btn").removeClass("toggle")
    $(this).addClass("toggle")
   })
   

这是 snippet
