1 ng-repeat指令: 循环输出数组或者对象内容到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">
	<script src="js/lib/angular.min.js"></script>
	<style type="text/css">
		*{margin: 0;padding: 0;}
	</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>介绍</th>
				</tr>
			</thead>
			<tbody>
				<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: "慕容复",content: "金庸武侠悲剧人物，曾与主角乔峰大战百余回合而未落败。"},
				{name: "张无忌",content: "金庸武侠一代传奇高手，擅长九阳神功以及乾坤大挪移。"},
				{name: "慕容复",content: "金庸武侠悲剧人物，曾与主角乔峰大战百余回合而未落败。"},
				{name: "张无忌",content: "金庸武侠一代传奇高手，擅长九阳神功以及乾坤大挪移。"},
			];
		});
	</script>
</body>
</html>

页面：一条数据占一行，若是分行显示则不容易实现。css

2 、 ng-repeat-start ng-repeat-end指令: 将数组或对象的一条数据分行显示。html

<!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">
	<script src="js/lib/angular.min.js"></script>
	<style type="text/css">
		*{margin: 0;padding: 0;}
	</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",[]);
		app.controller('myCtrl', function($scope) { 
			$scope.list = [
				{name: "慕容复",content: "金庸武侠悲剧人物，曾与主角乔峰大战百余回合而未落败。"},
				{name: "张无忌",content: "金庸武侠一代传奇高手，擅长九阳神功以及乾坤大挪移。"},
				{name: "慕容复",content: "金庸武侠悲剧人物，曾与主角乔峰大战百余回合而未落败。"},
				{name: "张无忌",content: "金庸武侠一代传奇高手，擅长九阳神功以及乾坤大挪移。"},
			];
		});
	</script>
</body>
</html>

页面：实现分行显示一条数据。java

参数结构：json

    {
        "layerId": "5569",
        "layerName": "layer0",
        "experiments": [

            }
        ]
    },

            }
        ]
    }
]
