使用Id访问table对象，使用Id访问Input对象

先看例子(好吧无意中发现可以通过Id访问DOM元素，如div)

<!DOCTYPE html>
<html>
	<head>
		<meta charset="utf-8" />
		<title>hello</title>
		<!-- <script src="js/myjs.js"></script> -->
	</head>
	<body>
		
		<table id="test">
			<tr>
				<td>hello</td>
			</tr>
		</table>
		<script>
			// test.deleteRow(0);
		</script>
	</body>
</html>

运行结果:

再看一个例子：

<!DOCTYPE html>
<html>
	<head>
		<meta charset="utf-8" />
		<title>hello</title>
		<!-- <script src="js/myjs.js"></script> -->
	</head>
	<body>
		
		<input id="test" value="100" />
		<script>
			document.write(test.value);
		</script>
	</body>
</html>

运行结果为:

表单对象可以通过name属性访问

<!DOCTYPE html>
<html>
	<head>
		<meta charset="utf-8" />
		<title>hello</title>
		<!-- <script src="js/myjs.js"></script> -->
	</head>
	<body>
		
		<form name="test1">
			<input name="test2" value="100" />
		</form>
		<script>
			document.write(test1.test2.value);
		</script>
	</body>
</html>
