Question

如何选择＆＃34; Mr＆＃34;选项 ？我试过了，但没用！

<div id="select-title" class="wrapper-dropdown-3 active" tabindex="1">
  <span>Mr</span>
  <ul class="dropdown">
    <li>
      <a href="#"></a>
    </li>
    <li>
      <a href="#">Mr</a>
    </li>
    <li>
      <a href="#">Ms</a>
    </li>
    <li>
      <a href="#">Mrs</a>
    </li>
    <li>
      <a href="#">Miss</a>
    </li>
    <li>
      <a href="#">Dr</a>
    </li>
    <li>
      <a href="#">Other</a>
    </li>
  </ul>
  <input data-val="true" data-val-required="Title is required" id="title" name="Title" type="hidden" value="Mr">
</div>
