我已将 AngularJS 测试项目移至 app.js、controllers.js 和 Services.js 中。之后我的项目无法运行，甚至没有一个页面可以正常工作。

我已在此处附加了我的主要源文件以及异常屏幕截图

计算器.html

<div ng-controller="CalculatorCtrl">
        Enter a number:
        <input type="number" ng-model="number" />
        <button ng-click="doSquare()">X<sup>2</sup></button>
        <button ng-click="doCube()">X<sup>3</sup></button>

        <div>Answer: {{answer}}</div>
    </div>

最佳答案

这是因为您在 Controller 和模块中混合了注入(inject)依赖项的数组表示法。

Controller.js

'use strict';

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

app.controller('CalculatorCtrl', ['$scope', '$http', 'CalculatorService', function($scope, $http, CalculatorService){

   console.log('in CalculatorCtrl...');
    $scope.doSquare = function() {
     $scope.answer = CalculatorService.square($scope.number);
   };

    $scope.doCube = function() {
     $scope.answer = CalculatorService.cube($scope.number);
   };

}]);

更新:删除函数doSquare和doCube中的$scope和CalculatorService ，它们已经作为依赖项包含在您的 Controller 中。以上更新版本。
