在 ionic 项目中显示来自 json 文件的数据

Question

我在获取 ionic 项目的输出时遇到问题，其中数据由 json 文件获取。即使我仔细检查了语法错误，我也找不到错误。我尝试使用离子命令，但结果是一样的

   

Angular modules

angular.module('starter', ['ionic'])

.run(function($ionicPlatform) {
  $ionicPlatform.ready(function() {
    if(window.cordova && window.cordova.plugins.Keyboard) {
      

      
      cordova.plugins.Keyboard.disableScroll(true);
    }
    if(window.StatusBar) {
      StatusBar.styleDefault();
    }
  });
})

.controller('ListController',['$scope','$http', function($scope,$http){
    $http.get('js/cars.json).success(function(data){
        $scope.cars=data;
    });
}]);

//Json file

{
    data: [{
        manufacturer: 'Porsche',
        model: '911',
        price: 135000,

Answer 1

您的代码存在一些格式问题。首先，您需要在 JSON 文件中使用双引号，如下所示：

{
    "data": [{
        "manufacturer": "Porsche",
        "model": "911",
        "price": "135000",
        "wiki": "Dr.-Ing. h.c. F. Porsche AG, usually shortened to Porsche AG, is a German automobile manufacturer specializing in high-performance sports cars, SUVs and sedans",
        "img": "2004_Porsche_911_Carrera_type_997.jpg"
    },{
        "model": "GT-R",
        "manufacturer": "Nissan",
        "price": "80000",
        "wiki":"Nissan Motor Company Ltd, usually shortened to Nissan, is a Japanese multinational automobile manufacturer headquartered in Nishi-ku, Yokohama, Japan",
        "img": "250px-Nissan_GT-R.jpg"
    },{
        "manufacturer": "BMW",
        "model": "M3",
        "price": "60500",
        "wiki":"Bayerische Motoren Werke AG, usually known under its abbreviation BMW, is a German luxury vehicles, motorcycle, and engine manufacturing company founded in 1916",
        "img": "250px-BMW_M3_E92.jpg"
    },{
        "manufacturer": "Audi",
        "model": "S5",
        "price": "53000",
        "wiki":"Audi AG is a German automobile manufacturer that designs, engineers, produces, markets and distributes luxury vehicles. Audi oversees worldwide operations from its headquarters in Ingolstadt, Bavaria, Germany",
        "img": "250px-Audi_S5.jpg"
    },{
        "manufacturer": "Ford",
        "model": "TT",
        "price": "40000",
        "wiki":"Audi AG is a German automobile manufacturer that designs, engineers, produces, markets and distributes luxury vehicles. Audi oversees worldwide operations from its headquarters in Ingolstadt, Bavaria, Germany",
        "img": "250px-2007_Audi_TT_Coupe.jpg"
    }]
}

您也没有访问正确的对象。下面一行：

$scope.cars=data;

应改为：

$scope.cars=data.data;

data 包含 $http.get 结果，它是整个 JSON 对象，因此您实际上想要遍历 data.data.

你这里也少了一个单引号:

$http.get('js/cars.json)

将其更改为：

$http.get('js/cars.json')

这些更改应该可以解决您的问题。
