<!DOCTYPE html>
<html ng-app="dayApp">
	<head>
		<meta charset="UTF-8">

		<link rel="stylesheet" href="../css/bootstrap.css" />
		<link rel="stylesheet" href="../css/bootstrap-theme.css" />

			<h1 ng-controller="tomCtl">明天是：{{day || "(未知)"}}</h1>
		</div>
	</body>
</html>

原因：

（1）缺少右大括号“}”

（2）缺少AngularJS模块和控制器结合控制

3、解决办法

<!DOCTYPE html>
<html ng-app="dayApp">
	<head>
		<meta charset="UTF-8">
		<title></title>
		<link rel="stylesheet" href="../css/bootstrap.css" />
		<link rel="stylesheet" href="../css/bootstrap-theme.css" />
		<script type="text/javascript" src="../js/angular.js" ></script>
		<script>
			var app = angular.module("dayApp",[]);
			
			app.controller("dayCtl",function($scope){
				
			});
			
			app.controller("tomCtl",function($scope){
				
			});
		</script>
	</head>
	<body>
