我想写一个简单的servcies代码如下： define([‘angular’], function (angular) {

return angular.module('services', [])

.service('UserService', function($http) {
    
    return {};
});

});

然后我想在controllers里面去注入它 define([‘angular’], function(angular) {

var app = angular.module('controllers', ['services']);
app.controller('RegisterController', ['UserService','$scope', function($scope, UserService) {
    $scope.password = "";
    $scope.repeatpwd = "";
    $scope.loginname = "";

    $scope.register = function() {
        console.log('dd');
    };
}]);
return app;

}); 通过debug的时候，进入到这个controller并没有出现任何问题，然而，当我想通过一个注册按钮来调用UserService中的方法时，却出现了下面的错误： TypeError: v2.register is not a function at fn (eval at <anonymous> (http://cdn.bootcss.com/angular.js/1.5.0/angular.js:14086:15), <anonymous>:4:215) at expensiveCheckFn (http://cdn.bootcss.com/angular.js/1.5.0/angular.js:15076:18) at callback (http://cdn.bootcss.com/angular.js/1.5.0/angular.js:24546:17) at Scope.$eval (http://cdn.bootcss.com/angular.js/1.5.0/angular.js:16820:28) at Scope.$apply (http://cdn.bootcss.com/angular.js/1.5.0/angular.js:16920:25) at HTMLFormElement.<anonymous> (http://cdn.bootcss.com/angular.js/1.5.0/angular.js:24551:23) at HTMLFormElement.m.event.dispatch (http://cdn.bootcss.com/jquery/1.11.2/jquery.min.js:3:8549) at HTMLFormElement.r.handle (http://cdn.bootcss.com/jquery/1.11.2/jquery.min.js:3:5252)

希望热心的网友能帮忙看下问题出在哪里了！
