JavaScript——删除Dom节点

 

删除节点的步骤：先获取父节点，再通过父节点删除自己

<div id="father">
       <h1>标题一</h1>
       <p id="p1">p1</p>
       <p class="p2">p2</p>
</div>

<script>
     var self=document.getElementById(p1);
     var father=p1.parentElement;
     father.removeChild(self)

    //删除是一个动态的过程：
    father.removeChild(father.children[0])
    father.removeChild(father.children[1])
    father.removeChild(father.children[2])
</script>

注意：删除多个节点的时候，children是在时刻变化的，删除节点的时候一定要注意！
