我在尝试使用 ui.router 时遇到错误:

angular.module('bApp', ['ui.router']);
angular.module('bApp').config(function($stateProvider, $urlRouterProvider) {
    urlRouterProvider.otherwise('/');

    $stateProvider
        .state('main', {
            url: "/",
            templateUrl: "/views/main.html"
        })

    .state('register', {
        url: "/register",

我尝试使用 ui.router 但失败。

最佳答案

因为你的 Angular 脚本标签位于 html head 中，所以有可能并非所有模块在使用时都已完成加载。

根据Where should I put <script> tags in HTML markup? ，这里有两个选择:

1. 将 defer 添加到头部的脚本标记中，这可能不适用于所有浏览器:

<script src="bower_components/jquery/dist/jquery.js" defer></script>
<script src="bower_components/angular/angular.js" defer></script>
<script src="bower_components/bootstrap/dist/js/bootstrap.js" defer></script>
<script src="bower_components/angular-ui-router/release/angular-ui-router.js" defer></script>

2.将它们放在 body 的底部。这适用于所有浏览器。

    ...

    <script src="bower_components/jquery/dist/jquery.js" defer></script>
    <script src="bower_components/angular/angular.js" defer></script>
    <script src="bower_components/bootstrap/dist/js/bootstrap.js" defer></script>
    <script src="bower_components/angular-ui-router/release/angular-ui-router.js" defer></script>

    <!-- build:js({.tmp,app}) scripts/scripts.js -->

    <script src="scripts/app.js"></script>
    <script src="scripts/controllers/main.js"></script>
    <script src="scripts/controllers/register.js"></script>
    <script src="scripts/app.config.js"></script>
    <!-- endbuild -->
    </div>
</body>
