感觉表单对象很特殊
<html>
<head>
<title>Html DOM demo</title>
</head>
<body>
<form id="form1Id" name=‘form1Name‘>
name:<input type="text" name="username" id="usernameId" />
</form>
<div name="mydivname" id="mydivid">hello</div>
<script type="text/javascript">
var fsForm1Id = document.form1Id;// document.getElementById("form1");
var fsForm1Name = document.form1Name;// document.getElementById("form1");
console.log("通过form-Id获取对象");
console.log(fsForm1Id);
console.log("\n");
console.log("通过form-name获取对象");
console.log(fsForm1Name);
console.log("\n");
console.log("在form中通过input-id获取input对象");
console.log(fsForm1Name.usernameId);
console.log("\n");
console.log("在form中通过input-name获取input对象");
console.log(fsForm1Name.username);
console.log("\n");
console.log(document.body);
console.log(document.body.mydivid);
console.log(document.body.mydivname);
</script>
</body>
</html>
