This article mainly introduces you to the example code of using jQuery to realize the swap position of the buttons in two p. Friends in need can refer to it. I hope it can help you.

The effect is as follows

##The code is as follows:

<head>
 <meta charset="utf-8" />
 <title></title>
 <script type="text/javascript" src="js/jquery-2.1.0.js"></script>
 <script type="text/javascript">
  $(function() {
   //定义一个变量等于所有button按钮
   var btns = $("button");
   //for循环进行遍历 
   for(var i = 0; i < btns.length; i++) {
    //i控制他的下标确定的是那个按钮的点击事件
    btns[i].onclick = function() {
     //判断如果此按钮的父控件是p1
     if($(this).parent().is("#p1")) {
      //移除此按钮
      $(this).remove();
      //转移到p2
      $(this).appendTo("#p2")
     } else {
      //否则他的父控件是p2 那么就把他移动到p1
      $(this).appendTo("#p1")
     }
    }
   }
  });
 </script>
</head>
<style>
 p {
  width: 500px;
  height: 200px;
  border: 1px;
  background-color: beige;
 }
 button {
  width: 50px;
  height: 30px;
 }
</style>
<body>
 <p id="p1">
  <p>我选择的：</p>
 </p>
 <p id="p2">
  <p>还可以选：</p>
  <button>数学</button>
  <button>英语</button>
