Question

我似乎无法完成这项工作。我一直在尝试按特定ID过滤JSON文件，然后使用ng-repeat进行迭代。

这是我尝试过的事情

这里是按钮触发器：

<a href="#/compare-details"><button class="viewDetails" ng-click="passID(11,02,00)" type="button">test button</button></a>

传递3个id参数后

，它会转到我的控制器：

var newData;
angular.module('handsetExplorerModule')
.controller("compareDetailsController", ['$scope','compareDetailsService', function($scope, compareDetailsService) {

   compareDetailsService.getHandsetList()
   .then(
       function(data){

         $scope.passID = function(id1,id2,id3){

             for(int i=0; i<data.phones.length; i++){
                if(data.phones[i].id == id1 || data.phones[i].id == id2 || data.phones[i].id == id3){
                     newData += data.phones[i];
                 }   
             }
         }
       }, 
       function(error){
           //todo: handle error
       }
    );

     $scope.phoneContent = newData;

}]);

JSON文件来自服务：

angular.module('handsetExplorerModule')
.factory('compareDetailsService', ['$http','$q', function($http, $q) {
   var service = {
   };
   service.getHandsetList = function(){
     var deferred = $q.defer();
      $http.get("./data/compareJSON.json").then(function(response) {
            deferred.resolve(response.data);
    },
        function(response){
            deferred.reject("ERROR: Unable to get handsetList data");
        }
    );
    return deferred.promise;
   };

   return service;
 }]);

和我的ng-repeat

<div id="divContent">
            <div>
            <table id="Content"  ng-repeat="x in phoneContent">
            <tr>
                <td class="one">
                    <table>
                    <tr>
                        <td><img class="contImage" ng-src="{{x.image}}" ng-alt="{{x.name}}" /></td>
                        <td class="textAlign">{{x.name}} <button class="viewDetails" ng-click="viewDetails(x.id)" type="button">VIEW DETAILS</button></td>
                    </table>
                </td>   
                <td class="two">{{x.size}}</td>
                <td class="one">{{x.storage}}</td>
                <td class="two">{{x.camera}}</td>
                <td class="one">{{x.battery}}</td>
                <td class="two">{{x.network}}</td>
                <td class="one">{{x.sim}}</td>
            </tr>
            </table>
            </div>      
</div>

请检查重构一点点：http://plnkr.co/edit/paPSj8Dm4Z1RCbFw9FmS?p=preview

它自己的BTW， $ http 服务是Promise，所以不需要使用 $ q 服务，只需返回 $ http ：

myApp.factory('compareDetailsService', ['$http', function($http) {
  return {
    getHandsetList: function(){
      return $http.get("data.json");
    }
  };
}]);

有一个非常类似的教程，你应该看看：https://docs.angularjs.org/tutorial/step_00
