<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

  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');
