This time I will bring you JS to add a new element node. What are the precautions for adding a new element node to JS? The following is a practical case, let's take a look.

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>www.jb51.net - JS添加新节点的几种方法</title>
</head>
<body>
<p id="d">
<span id="s">
  1234567890
</span>
</p>
</body>
<script type="text/javascript">
  //首先找到Id为d的元素
  var d=document.getElementById('d');
  //创建一个节点
  var a=document.createElement('a');
  //设置a的属性
  a.href='https://www.baidu.com/';
  a.innerText='ggggg';
  //添加元素  将创建的节点添加到Id为d的p里
  d.appendChild(a);
  //在指定节点前插入新节点
  var p=document.createElement('p');
  //添加文本内容
  p.innerText='ppppppppppppppppp';
  //d.appendChild(p);
  //参数1：要添加的元素 参数2：要放到哪个节点的前面
  d.insertBefore(p,a);
  //获取目标元素
  var s=document.getElementById('s');
  //克隆新元素
  var spanc= s.cloneNode(true);//默认参数是false
  d.appendChild(spanc);
</script>
</html>
