javascript getElementbyTabname属性

 

 

getElementbyTabname方法与getElementbyName属性相似，都为一个dom对象集合

<head>
    <meta charset="UTF-8">
    <title>Title</title>
    <script type="text/javascript">
        window.onload = function () {
            var btnObj = document.getElementById("btn");
            btnObj.onclick = function () {
                var inputs = document.getElementsByTagName("input");
                for (var i = 0; i < inputs.length; i++) {
                    inputs[i].checked = true;
                }
            }
        }
    </script>
</head>
<body>
<p><input type="checkbox">java</p>
<p><input type="checkbox">c</p>
<p><input type="checkbox">php</p>
<p>
    <button id="btn">全选</button>
</p>
</body>
