删除DOM节点

删除节点

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！
