在Ionic項目中顯示JSON文件中的數據
[英]Display data from json file in ionic project
問題描述
我在獲取ionic項目的輸出時遇到問題，其中json文件提取了數據。 即使我仔細檢查了語法錯誤，也找不到該錯誤。 我嘗試使用離子命令，但結果相同
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, wiki: 'Dr.-Ing. hc F.

您的代碼存在一些格式問題。 首先，您需要在JSON文件中使用雙引號，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"
}]
}
您也沒有訪問正確的對象。 下一行：
$scope.cars=data;
應更改為：
$scope.cars=data.data;
data包含$http.get結果，該結果是整個JSON對象，因此您實際上要遍歷data.data 。
您在這里也缺少單引號：
$http.get('js/cars.json)
更改為：
$http.get('js/cars.json')
這些更改將解決您的問題。
