How to implement jQuery multi-condition filtering

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>

After arranging the content, add css styles to the page content and load related js.

<link rel="stylesheet" type="text/css" href="css/style.css">  
<script type="text/javascript" src="js/jquery.js"></script>  
<script type="text/javascript" src="js/script.js"></script>

jQuery
When the user clicks on any condition, the current selected state is marked, and the adjacent condition is unchecked. , and update the content of the selected condition container, please see the code:

$(document).ready(function() { 
  $("#select1 dd").click(function() { 
    $(this).addClass("selected").siblings().removeClass("selected"); 
    if ($(this).hasClass("select-all")) { 
      $("#selectA").remove(); 
    } else { 
      var copyThisA = $(this).clone(); 
      if ($("#selectA").length > 0) { 
        $("#selectA a").html($(this).text()); 
      } else { 
        $(".select-result dl").append(copyThisA.attr("id", "selectA")); 
      } 
    } 
  }); 
  $("#select2 dd").click(function() { 
    $(this).addClass("selected").siblings().removeClass("selected"); 
    if ($(this).hasClass("select-all")) { 
      $("#selectB").remove(); 
    } else { 
      var copyThisB = $(this).clone(); 
      if ($("#selectB").length > 0) { 
        $("#selectB a").html($(this).text()); 
      } else { 
        $(".select-result dl").append(copyThisB.attr("id", "selectB")); 
      } 
    } 
  }); 
  $("#selectA").live("click", 
  function() { 
    $(this).remove(); 
    $("#select1 .select-all").addClass("selected").siblings().removeClass("selected"); 
  }); 
  $("#selectB").live("click", 
  function() { 
    $(this).remove(); 
    $("#select2 .select-all").addClass("selected").siblings().removeClass("selected"); 
  }); 
  $(".select dd").live("click", 
  function() { 
    if ($(".select-result dd").length > 1) { 
      $(".select-no").hide(); 
    } else { 
      $(".select-no").show(); 
    } 
  }); 
});
