Angular JS - 不是一个函数

Question

我在controller.js中遇到错误

controller.js

factory.js

angular.module('myApp', ['ngRoute', 'ui.router']).controller('authCtl', ["$scope", "$rootScope", "loginService", function($scope, $rootScope, loginService) {
  $rootScope.bodyClass = "focusedform";
  $scope.submitForm = function() {
    loginService.userAuth($scope.username, $scope.password);
  }
}]);

你没有在工厂归还你的物品。

您必须将您的方法变量附加到对象中并从工厂返回，以便从控制器进行访问。

试试这个

angular.module('warApp').factory('loginService', ["$http", "$q", function($http, $q) {
  var userFactory = {};
  userFactory.userAuth = function(username, password) {
    console.log(username + '' + password);
  };
  return userFactory;
}]);

或尝试这样以获得更好的视图

angular.module('warApp').factory('loginService', ["$http", "$q", function($http, $q) {
  var userFactory = {
    userAuth: userAuth
  }
  return userFactory;
  function userAuth(username, password) {
    console.log(username + '' + password);
  }
}]);
