This article mainly introduces jquery to implement multi-condition filtering effects. It is recommended to everyone. Friends in need can refer to it.

The example in this article describes how jquery implements multi-condition filtering effects. Share it with everyone for your reference. The details are as follows:
When we purchase goods on the e-commerce platform, we filter and query based on brand, style, price range and other conditions on the product list page. When a certain condition is clicked, the set of conditions selected by the user will be displayed on the page. , and display the corresponding product information that meets the conditions. So today we use jQuery to achieve this front-end effect.
Running rendering:

HTML
First, we classify the query conditions and arrange the condition container li.select- list and selected condition container p.select-result.

<ul class="select">  
    <li class="select-list">  
      <dl id="select1">  
        <dt>上装：</dt>  
        <dd class="select-all selected"><a href="#">全部</a></dd>  
        <dd><a href="#">针织衫</a></dd>  
        <dd><a href="#">毛呢外套</a></dd>  
        <dd><a href="#">T恤</a></dd>  
        <dd><a href="#">羽绒服</a></dd>  
        <dd><a href="#">棉衣</a></dd>  
        <dd><a href="#">卫衣</a></dd>  
        <dd><a href="#">风衣</a></dd>  
      </dl>  
    </li>  
    <li class="select-list">  
      <dl id="select2">  
        <dt>裤装：</dt>  
        <dd class="select-all selected"><a href="#">全部</a></dd>  
        <dd><a href="#">牛仔裤</a></dd>  
        <dd><a href="#">小脚/铅笔裤</a></dd>  
        <dd><a href="#">休闲裤</a></dd>  
        <dd><a href="#">打底裤</a></dd>  
        <dd><a href="#">哈伦裤</a></dd>  
      </dl>  
    </li>  
    <li class="select-result">  
      <dl>  
        <dt>已选条件：</dt>  
        <dd class="select-no">暂时没有选择过滤条件</dd>  
      </dl>  
    </li>  
  </ul>

      $("#selectA").remove();

      var copyThisA = $(this).clone(); 
      if ($("#selectA").length > 0) { 
        $("#selectA a").html($(this).text()); 
      } else { 
        $(".select-result dl").append(copyThisA.attr("id", "selectA"));
