角度控制器不显示数据

我是新手开发一个Angular应用程序。

我有两种观点:

  1. Main:搜索元素。
  2. 结果:显示查询结果。
  3. 搜索器表单位于视图中,并且包含在(主视图和结果)视图中。两个视图都链接到同一个控制器。

    问题是,当我在主视图中单击搜索时,将调用服务并返回值,但结果不会显示在结果视图中。

    如果我在结果视图中执行相同的查询,则一切正常并显示结果。

    代码:

    主视图和结果包含完全相同的seacher视图:

    <div ng-include src="'partials/boat-searcher.html'" class="text-center"></div>
    

    搜索者观点:

    <input type="text" ng-model="departure" typeahead="suggestion for suggestion in cities($viewValue)" class="input-xlarge input-height-large" placeholder="Salida" autocomplete="off">
    

    我的应用:

    angular.module('myApp', ['myApp.filters', 'myApp.services', 'myApp.directives', 'myApp.controllers']).
      config(['$routeProvider', '$httpProvider', function($routeProvider, $httpProvider) {    
        $routeProvider.when('/home', {templateUrl: 'partials/home.html', controller: 'BoatListCtrl'});        
        $routeProvider.when('/option-list', {templateUrl: 'partials/option-list.html', controller: 'BoatListCtrl'});
      }]);
    

    我的控制器:

    .controller('BoatListCtrl', function BoatListCtrl($scope, $location, $routeParams, $http, Boat, Equipment, Extra) {
    // Departures typeahead
            $scope.departure = undefined;       
            $scope.cities = function(cityName) {            
                return $http.get("http://localhost:3000/departures?query="+cityName).then(function(response){               
                    var names = response.data.map(function (source) { return source.name; });                
                    return names;
                });
            };      
    
    
            // Gets options (boats)
            $scope.getOptionList = function(departure, fechaSalida, fechaLlegada, personas) {                       
                $scope.boats = Boat.query({departure: departure, fechaSalida: fechaSalida, fechaLlegada: fechaLlegada, personas: personas});    
                $location.path('/option-list');                                         
            };

答案 0 :(得分:0)

我终于自己解决了。所以,我将解释我是如何做到的:

  1. 使用查询表单查看:

    <form class="form-search">      
    <input type="text" ng-model="departure" typeahead="suggestion for suggestion in cities($viewValue)" class="input-xlarge input-height-large" placeholder="Salida" autocomplete="off">
    // Your form query fields                                
    <button class="btn btn-large btn-primary" ng-click="getOptionList(departure, fechaSalida, fechaLlegada, personas)"><i class="icon-search icon-white icon-small"></i> Buscar</button>                
    

  2. 在我的HomeCtrl中(这是我查询的控制器,但我想在另一个视图中显示另一个控制器:

    .controller('HomeCtrl', function HomeCtrl($scope, $location, $http, $filter, Boat, BoatService, SearcherService) {
    
        // Gets options (boats)
        $scope.getOptionList = function(departure, departureDate, arrivalDate, people) {                        
            $scope.formattedDepartureDate  = $filter('date')(departureDate,'yyyy-MM-dd');           
            $scope.formattedArrivalDate = $filter('date')(arrivalDate,'yyyy-MM-dd');              
            $scope.people = people;             
            $scope.boats = Boat.query({departure: departure, departureDate: $scope.formattedDepartureDate, arrivalDate: $scope.formattedArrivalDate, people: $scope.people});               
            BoatService.setBoats($scope.boats);     
            $location.path('/option-list');                                         
        };
    })
    
  3. 注意:重要的是要注意,我获得了一个范围变量的船只列表,我将它设置在一个带有BoatService.setBoats的服务中(此服务将可用于下一个控制器以获取船只。)

    1. 我的boat-list.html视图

      <div class="row-fluid" ng-repeat='boat in boats'>
        {{boat.name}}
        ...
      
    2. BoatListCtrl(在另一个视图中显示船只):

       .controller('BoatListCtrl', function BoatListCtrl($scope, $location, $http, $filter, SearcherService, Boat, BoatService, Equipment, Extra, 
                                                        Rating, Comment, Booking, BookingService) {               
      
          $scope.boats = BoatService.getBoats();
        };
