  var _btns = document.querySelectorAll('.btn'),

    _eachBtn = function(callback) {
      Array.prototype.forEach.call(_btns, function(elem) {
        callback.call(this, elem);
      });
    },
    _initListener = function(e) {
      e.preventDefault();
      e.stopPropagation();
      _eachBtn(function(btn) {
        btn.classList.remove('dropdown-open')
      });
      this.classList.toggle('dropdown-open');

Answer 1

只需像这样在 LI 标签内添加链接

 <div class="dropdown">
  <a href="#" class="btn">
    Dropdown
  </a>
  <div class="outer-list">
    <ul>
      <li><a href="http://www.google.co.uk">List item 1</a></li>
      <li><a href="http://www.google.co.uk">List item 2</a></li>
      <li><a href="http://www.google.co.uk">List item 3</a></li>
      <li><a href="http://www.google.co.uk">List item 4</a></li>
    </ul>
  </div>
