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" } }); </script> </body> </html>
