如何使用list.js选择下拉选项对列表项进行排序

Question

我使用list.js对列表项进行排序，但我想在更改select > option时对该项进行排序。

<div id="hotels">
    <input class="search" placeholder="Search" />
    <button class="sort" data-sort="name">
      Sort by name
    </button>

    <select class="sort" data-sort="">
      <option value="" selected>Sort by</option>
      <option value="hotelName">Hotel Name</option>
      <option value="price">Price</option>
      <option value="star">Star</option>
    </select>

    <ul class="list">
      <li>
        <h3 class="hotelName">The Umrao</h3>
        <p class="price">5002</p>
        <p class="star">3</p>
      </li>
      <li>
        <h3 class="hotelName">Welcomhotel Dwarka, New Delhi</h3>
        <p class="price">8367</p>
        <p class="star">5</p>
      </li>
      <li>
        <h3 class="hotelName">Lemon Tree Premier, Delhi Airport</h3>
        <p class="price">3978</p>
        <p class="star">4</p>
      </li>
      <li>
        <h3 class="hotelName">Red Fox Hotel, Delhi Airport</h3>
        <p class="price">9676</p>
        <p class="star">2</p>
      </li>
    </ul>
  </div>
  <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
  <script src="http://listjs.com/no-cdn/list.js"></script>

我已经做了一些代码，但是当我选择第一次工作时，它是有缺陷的，但是如果我在单击select时再次更改，使用前面的值选择它，然后在下拉打开之后，选择它，然后用当前值进行排序。

这里是我的代码

var options = {
  valueNames: [ 'hotelName', 'price', 'star' ]
};

var hotelList = new List('hotels', options);

$('.sort').change(function(){
  var selection = $(this).val();
  console.log(selection);
  $(this).attr('data-sort', selection);
});

为此，您应该使用hotelList.sort函数：

​

var options = {
  valueNames: [ 'hotelName', 'price', 'star' ]
};

var hotelList = new List('hotels', options);

$('select.sort').change(function(){
  var selection = $(this).val();
  hotelList.sort(selection);
});

$('button.sort').click(function() {
  hotelList.sort($(this).data('sort'));  
});

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
<script src="http://listjs.com/no-cdn/list.js"></script>
<div id="hotels">
  <input class="search" placeholder="Search" />
  <button class="sort" data-sort="hotelName">
    Sort by name
  </button>

  <select class="sort">
    <option value="" selected>Sort by</option>
    <option value="hotelName">Hotel Name</option>
    <option value="price">Price</option>
    <option value="star">Star</option>
  </select>

  <ul class="list">
    <li>
      <h3 class="hotelName">The Umrao</h3>
      <p class="price">5002</p>
      <p class="star">3</p>
    </li>
    <li>
      <h3 class="hotelName">Welcomhotel Dwarka, New Delhi</h3>
      <p class="price">8367</p>
      <p class="star">5</p>
    </li>
    <li>
      <h3 class="hotelName">Lemon Tree Premier, Delhi Airport</h3>
      <p class="price">3978</p>
      <p class="star">4</p>
    </li>
    <li>
      <h3 class="hotelName">Red Fox Hotel, Delhi Airport</h3>
      <p class="price">9676</p>
      <p class="star">2</p>
    </li>
  </ul>
</div>
