我是离子框架的初学者。我已将模板加载到索引文件中，但无法从登录屏幕移动到注册屏幕。请看看我的代码，让我知道有什么问题。

应用程序.js
angular.module('ionicApp', ['ionic'])
.config(function($stateProvider, $urlRouterProvider) {
$stateProvider
.state('login', {
url: '/login',
templateUrl: 'templates/login.html',
//controller: 'loginControl'
})
.state('signup', {
url: '/signup',
templateUrl: 'templates/signup.html',
//controller: 'signupControl'
})
$urlRouterProvider.otherwise('/login');
}) // Main Controller Ends
如果我从控制器中删除评论，页面就会受到干扰。
