Implement dragging icons to the recycle bin and deleting them based on jQuery_jquery

This article uses jQuery to implement a drag-and-drop function to delete small desktop icons. It works just like the recycle bin of the operating system. We only need to drag the application icon to the trash can to delete the icon. Share it with everyone and implement it in detail. The method is as follows

Operation rendering:

Introducing core files
Here you need to introduce jquery, jquery ui, and jquery ui css

<link rel="stylesheet" href="assets/css/jquery-ui.css" />
<script src="js/jquery/1.8.3/jquery.min.js"></script>
<script src="js/jqueryui/1.9.2/jquery-ui.min.js"></script>

Build html

<div id="main">
 <div class="folder">
  <div class="front"></div>
  <div class="back"></div>
 </div>
  <img src="assets/48px/Implement dragging icons to the recycle bin and deleting them based on jQuery_jquery.png"   style="max-width:90%" alt="Implement dragging icons to the recycle bin and deleting them based on jQuery_jquery" /> 
  <img src="assets/48px/calculator.png"   style="max-width:90%" alt="calculator" />

  <img src="assets/48px/console.png"   style="max-width:90%" alt="console" />

</div>

    front = folder.find('.front'), //文件夹前面部分
    img = $("#main img"), //容器main中的所有图片
    droppedCount = 0;  //记数器
 
  img.draggable(); //使所有图片可以拖拽
 
  folder.droppable({ //droppable事件,即拖拽到文件夹时触发的事件
    drop : function(event, ui) {//释放时触发
       
      // 移动拖拽的图片
      ui.draggable.remove();
       
      // 给计数器加1
      front.text(++droppedCount);
       
    },
     
    activate : function(){ //拖拽时让文件夹打开
       
      folder.addClass('open');
    },
     
    deactivate : function(){ //停止拖拽时让文件夹关闭
      folder.removeClass('open');
    }
  });
