This time I will bring you jQuery’s drag-and-drop function to the recycle bin for deletion. What are the precautions for jQuery’s drag-and-drop function to the recycle bin and delete function? The following is a practical case. Let’s take a look. one time. Running renderings:

##Introducing core filesYou 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

<p id="main">
 <p class="folder">
  <p class="front"></p>
  <p class="back"></p>
 </p>
  <img src="assets/48px/box.png" style="top:340px;left:100px;" alt="box" /> 
  <img src="assets/48px/calculator.png" style="top:340px;left:170px;" alt="calculator" /> 
  <img src="assets/48px/clipboard.png" style="top:340px;left:240px;" alt="clipboard" /> 
  <img src="assets/48px/console.png" style="top:340px;left:310px;" alt="console" /> 
  <img src="assets/48px/basketball.png" style="top:340px;left:380px;" alt="basketball" /> 
  <img src="assets/48px/facebook.png" style="top:400px;left:100px;" alt="facebook" /> 
  <img src="assets/48px/gift.png" style="top:400px;left:170px;" alt="gift" /> 
  <img src="assets/48px/id_card.png" style="top:400px;left:240px;" alt="id card" /> 
  <img src="assets/48px/imac.png" style="top:400px;left:310px;" alt="imac" /> 
  <img src="assets/48px/system_monitoring.png" style="top:400px;left:380px;" alt="system monitoring" />

Writing JS

$(function() {
  var folder = $("#main .folder"),  //文件夹
    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');
    }
  });
});
