AngularJS $http 是一个用于读取web服务器上数据的服务。
$http.get(url) 是用于读取服务器数据的函数。
<meta charset="utf-8"> <script src="http://apps.bdimg.com/libs/angular.js/1.4.6/angular.min.js"></script> </head> <body> <div ng-app="myApp" ng-controller="customersCtrl"> <ul> <li ng-repeat="x in names"> {{ x.Name + ‘, ‘ + x.Country }} </li> </ul> </div> <script> var app = angular.module(‘myApp‘, []); app.controller(‘customersCtrl‘, function($scope, $http) { $http.get("Customers.json") .success(function(response) { $scope.names = response.records; }); }); </script> </body> </html>
应用解析:
注意：以上代码的 get 请求是本地Customers.json文件。
AngularJS 应用通过 ng-app 定义。应用在 <div> 中执行。
ng-controller 指令设置了 controller 对象 名。
控制器对象有一个属性: $scope.names。
$http.get() 读取静态 JSON 数据，$scope.names 变为一个数组。
