javascript基础--DOM选取父节点

一、parentNode

<!DOCTYPE html>
<html lang="en">

<head>
    <meta charset="UTF-8">
    <title>Document</title>
    <script>
        window.onload = function() {
            var aA = document.getElementsByTagName('a');
            var i = 0;
            for (i = 0; i < aA.length; i++) {
                aA[i].onclick = function() {
                    this.parentNode.style.display = "none"; //parentNode取父节点
                }
            }
        }
    </script>
</head>

<body>
    <ul id="ul1">
        <li>111<a href="javascript:;">删除</a></li>
        <li>222<a href="javascript:;">删除</a></li>
        <li>333<a href="javascript:;">删除</a></li>
    </ul>
</body>

</html>

 二、offsetParent（选取关联的父级）

<!DOCTYPE html>
<html lang="en">

<head>
    <meta charset="UTF-8">
    <title>Document</title>
</head>

<body>
    <div id="div1" style="width:100px;height:100px;background:red;margin:10px;position:relative;">
        <!--offsetParent是找他关联的父级-->
        <div id="div2" onclick="alert(this.offsetParent.id)" style="width:100px;height:100px;background:yellow;position:absolute;top:100px;left:100px;"></div>
    </div>
</body>

</html>
