Question

我是棱角分明的新人，我有下一个问题。我有两个jsp，第一个在我想要在mi第二个视图上使用的变量中设置一个值，我想用工厂来做，mi的问题是第一个视图正确设置了值，但是当我想要恢复时它在第二个，它是未定义的。我已经研究过了，但我找不到答案，任何人都可以帮助我。

这是我的第一个观点。

services.js

var app = angular.module('Modulo', []);

app.factory('Factoria',function(){


var regreso = {};

return{ getSaludo : function(nombre) {
        regreso = nombre;
        alert(regreso);
        return regreso;
    },getData : function(){
        return regreso;
    }
    }
return regreso;

});



app.controller("controladorForm", ['$scope','Factoria', function($scope,Factoria){

$scope.add = function(){
    $scope.nombreFac = Factoria.getSaludo($scope.nombre);
}

$scope.get = function(){
     $scope.nombreFac = Factoria.getData();
}


}
]);


 app.controller("controladorPresenta", ['$scope','$rootScope','Factoria',     function($scope,$rootScope,Factoria){
 $scope.nombreFac = Factoria.getData();
 alert(Factoria.getData());
}
]);

与工厂保持数据的角度
