我的代码是：

app.js

 (function () {
    "use strict";
    var app = angular.module("autoQuote",["ui.router"]);

    app.config(["$stateProvider","$urlRouterProvider", function($stateProvider,$urlRouterProvider){
        $urlRouterProvider.otherwise("/");

        $stateProvider
            .state("step1", {
              url : "/",
              templateUrl : "step1.html",
              controller: "questionsCtrl"
            })       
            .state("step2", {
              url : "/step2",
              templateUrl : "step2.html",
              controller: "questionsCtrl"
            })
    }]
    );
}());

questionsCtrl.js

(function () {
    "use strict";

    angular
    .module("autoQuote")
    .controller("questionsCtrl",["questionsCtrl"]);

    function questionsCtrl() {
        console.log('here in questionsCtrl');
    }

}());

定义控制器时需要参考该功能。

.controller("questionsCtrl", questionsCtrl);
                             ^^^^^^^^^^^^^     : Function reference, not a string

controller()的第一个参数是控制器的名称，第二个是映射。

我建议使用以下最小安全语法。

.controller('questionsCtrl', ['$scope', function ($scope) {

}]);

参考控制器功能

.controller('questionsCtrl', ['$scope', questionsCtrl]);

function questionsCtrl($scope) {
    console.log('In questionsCtrl');
}

angular js error：参数'questionsCtrl'不是函数
