我正在开发一个使用离子框架的应用程序。这又使用了 ui-router。目前，我有一个非常基本的两页应用程序。然而，它会扩大到更大。此时，当我从第一个视图转换到第二个视图时出现错误。错误说：
TypeError: Cannot read property '1' of null

我正在使用 Ionic Framework 的 1.0.0 beta 3。我的 app.js 文件如下所示：
"use strict";
var myApp = angular.module('myApp', ['ionic', 'ngRoute']);
myApp.config(function($stateProvider, $urlRouterProvider) {
$stateProvider
.state('intro', { url: '/', templateUrl: 'app/account/welcome.html', controller: 'WelcomeController' })
.state('login', { url: '/account/login', templateUrl: 'app/account/login.html', controller: 'LoginController '})
;
$urlRouterProvider.otherwise("/");
});
function WelcomeController($scope) {
}
function LoginController($scope) {
}
我的index.html 看起来像这样：
<!DOCTYPE html>
<html ng-app="myApp">
<head>
<meta charset="utf8">
<meta name="viewport" content="initial-scale=1, maximum-scale=1, user-scalable=no, width=device-width">
<title>MyApp</title>
<link rel="stylesheet" href="/vendor/ionic/release/js/ionic.bundle.min.js" />
<link rel="stylesheet" href="/css/app.css" />
<script type="text/javascript" src="/vendor/ionic/release/js/ionic.bundle.js"></script>
<script type="text/javascript" src="/vendor/angular-route/angular-route.min.js"></script>
<script type="text/javascript" src="/app/app.js"></script>
<script type="text/javascript" src="/app/controllers.js"></script>
</head>
<body>
<ion-nav-bar class="bar-positive" animation="nav-title-slide-ios7">
<ion-nav-back-button class="button-icon ion-arrow-left-c">
</ion-nav-back-button>
<h1 class="title">MyApp</h1>
</ion-nav-bar>
<ion-nav-view animation="slide-left-right">
</ion-nav-view>
</body>
</html>
welcome.html 看起来像这样：
<ion-view>
<br /><br />
<h1>Welcome</h1>
<a class="button" href="/#/account/login">Login</a>
</ion-view>
login.html 看起来像这样：
<ion-view>
<br /><br />
<h1>Login</h1>
</ion-view>
视图转换得很好。然而，我上面显示的错误让我担心。我担心它稍后会咬我的屁股。有谁知道这会是什么原因造成的？有谁知道我该如何解决这个问题？
谢谢你！
