AngularJS 实例

1、循环输出多个标题：

<!DOCTYPE html>
<html>
<head>
 <title>AngularJS 实例 | Web176教程网web176.com</title>
<meta charset="utf-8">
<script src="https://cdn.staticfile.org/angular.js/1.4.6/angular.min.js"></script>
</head>
<body ng-app="myApp" ng-controller="myCtrl">

<h1 ng-repeat="x in records">{{x}}</h1>

<script>
var app = angular.module("myApp", []);
app.controller("myCtrl", function($scope) {
  $scope.records = [
    "Web176教程1",
    "Web176教程2",
    "Web176教程3",
    "Web176教程4",
  ]
});
</script>

</body>
</html>

2、使用数组循环输出一个表格：

<!DOCTYPE html>
<html>
<head>
 <title>AngularJS 实例 | Web176教程网web176.com</title>
<meta charset="utf-8">
<script src="https://cdn.staticfile.org/angular.js/1.4.6/angular.min.js"></script>
</head>
<body ng-app="myApp">

<table ng-controller="myCtrl" border="1">
<tr ng-repeat="x in records">
  <td>{{x.Name}}</td>
  <td>{{x.Country}}</td>  
</tr>
</table>

<script>
var app = angular.module("myApp", []);
app.controller("myCtrl", function($scope) {
  $scope.records = [
    {
      "Name" : "Alfreds Futterkiste",
      "Country" : "Germany"
    },
    {
      "Name" : "Berglunds snabbk",
      "Country" : "Sweden"
    },
    {
      "Name" : "Centro comercial Moctezuma",
      "Country" : "Mexico"
    },
    {
      "Name" : "Ernst Handel",
      "Country" : "Austria"
    }
  ]
});
</script>

</body>
</html>

3、使用对象循环输出一个表格：

<!DOCTYPE html>
<html>
<head>
 <title>AngularJS 实例 | Web176教程网web176.com</title>
<meta charset="utf-8">
<script src="https://cdn.staticfile.org/angular.js/1.4.6/angular.min.js"></script>
</head>
<body ng-app="myApp">

<table ng-controller="myCtrl" border="1">
<tr ng-repeat="(x, y) in myObj">
  <td>{{x}}</td>
  <td>{{y}}</td>  
</tr>
</table>

<script>
var app = angular.module("myApp", []);
app.controller("myCtrl", function($scope) {
  $scope.myObj = {
    "Name" : "Alfreds Futterkiste",
    "Country" : "Germany",
    "City" : "Berlin"
  }
});
