1 ng-repeat指令: 循環輸出數組或者對象內容到htmljavascript

<!DOCTYPE html>
<html lang="en">
<head>
	<meta charset="UTF-8">
	<title>apply watch</title>
	<link rel="stylesheet" type="text/css" href="css/lib/bootstrap.css">

	</style>
</head>
<body ng-app="myApp" ng-controller="myCtrl">
	<div class="container-fluid">
		<table class="table table-striped">
			<thead>
				<tr>
					<th>姓名</th>
					<th>介紹</th>
				</tr>

				<tr ng-repeat="item in list">
					<td>{{item.name}}</td>
					<td>{{item.content}}</td>
				</tr>
			</tbody>
		</table>
	</div>
	<script type="text/javascript">
		var app = angular.module("myApp",[]);
		app.controller('myCtrl', function($scope) { 
			$scope.list = [
				{name: "慕容復",content: "金庸武俠悲劇人物，曾與主角喬峯大戰百餘回合而未落敗。"},

			];
		});
	</script>
</body>

頁面：一條數據佔一行，若是分行顯示則不容易實現。css

2 、 ng-repeat-start ng-repeat-end指令: 將數組或對象的一條數據分行顯示。html

<!DOCTYPE html>
<html lang="en">
<head>

	</style>
</head>
<body ng-app="myApp" ng-controller="myCtrl">
	<div class="container-fluid">
		<table class="table table-striped">
			<tbody>
				<tr ng-repeat-start="item in list">
					<td>姓名</td>
					<td>{{item.name}}</td>
				</tr>
				<tr ng-repeat-end>
					<td></td>
					<td>{{item.content}}</td>
				</tr>
			</tbody>
		</table>
	</div>
	<script type="text/javascript">
		var app = angular.module("myApp",[]);
