javascript里childNodes和children的区别 

<html>
<head>
    <script>
        function init() {
            for (var j = 0; j <= document.getElementById("dots").children.length; j++) {
                alert(document.getElementById("dots").childNodes[j].innerHTML);
                alert(document.getElementById("dots").children[j].innerHTML);
            }
        }
    </script>
</head>
<body onload="init()">
    <div id="dots" style="width: 500px; height: 20px;"><span id="a">first</span><span id="b">second</span><span id="c">third</span><span id="d">forth</span><span id="e">fifth</span><div></div></div>
