<!DOCTYPE html><html><head><meta charset="utf-8"><script src="http://apps.bdimg.com/libs/angular.js/1.4.6/angular.min.js"></script></head><body ng-app="myApp"><table ng-controller="myCtrl"><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>运行结果：
| Alfreds Futterkiste | Germany |

| Centro comercial Moctezuma | Mexico |
| Ernst Handel | Austria |
AngularJS 实例
使用对象循环输出一个表格:
<!DOCTYPE html><html><head><meta charset="utf-8"><script src="http://apps.bdimg.com/libs/angular.js/1.4.6/angular.min.js"></script></head><body ng-app="myApp"><table ng-controller="myCtrl"><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" }});</script></body></html>运行结果：
