控制器通$范围值到另一个控制器

Question

我很新的AngularJS，我怎么可以通过输入范围从第一控制器到第二个控制器的数据$ scope.requestURL

我搜索关于服务方法，但我不知道如何应用它。

.controller('ZipController', ['$scope', function($scope) { 
    $scope.zipCode = '10028'; 

    $scope.setURL = function() { 
    $scope.requestURL = 'http://congress.api.sunlightfoundation.com/legislators/locate?zip=' + $scope.zipCode + '&apikey=xxxxx'; 
    }; 

    }]) 

    .controller('ListController', ['$scope', '$http', 
    function($scope, $http) { 
    $http.get($scope.requestURL).success(function(data) { 
    console.log(data.results); 
    $scope.congress = data.results; 
    }); 
    }]); 

Answer 1

尝试将其设置为$ rootScope.requestURL并从第二个控制器访问它。

Answer 2

这里是一个快速的解决方案：..你不必使用$ HTTP核心的服务，为您的情况：

(function(angular) { 
    var app = angular.module('myServiceModule', []); 
    app.controller('ZipController', function($scope, myService) { 
     $scope.zipCode = '10028'; 
     myService.setFunc($scope.zipCode); 
     myService.zipCode = $scope.zipCode; 
    }); 
    app.controller('ListController', function($scope, myService) { 
     $scope.requestURL = myService.getFunc(); 
    }); 
    app.factory('myService', function() { 
     var zipCode; 
     var setFunc = function(zip) { 
      zipCode = zip; 
     }; 
     var getFunc = function() { 
      return 'http://congress.api.sunlightfoundation.com/legislators/locate?zip=' + zipCode + '&apikey=xxxxx' 
     }; 
     return { 
      zipCode: zipCode, 
      setFunc: setFunc, 
      getFunc: getFunc 
     }; 
    }); 
})(window.angular);
