Question

我正在构建一个非常简单的应用程序，它有2个标签。我模仿离子网站（标签）提供的样本。所以我有我的主index.html，tabs.html（用于标签导航页脚）和另外2个带有标签内容的html文件（实际上只是简单的文本）。当我运行我的应用程序（http://localhost:8100）时，页面被正确转发到默认选项卡地址（http://localhost:8100/#/tab/b2bviewer），并显示带有选项卡图标的选项卡页脚。但页面中没有内容。如果我单击第二个选项卡（设置），则网址正确更改（http://localhost:8100/#/tab/settings）但仍为空白页面。所有这一切都没有在浏览器控制台中出现任何错误。

所以我的第一个问题是：我该如何解决这种情况？行为错误，日志中没有任何内容。我在.js中添加了几个console.log，但我可以看到js已被执行。

第二个问题是：我的应用程序出了什么问题！？这里有一些比特和我的代码：

的index.html

您的代码存在一些问题。

定义状态时，使用views代替view指定视图：

.state('tab.b2bviewer', {
    url: '/b2bviewer',
    cache: false,
    views: {
        'tab-b2bviewer': {
            templateUrl: 'templates/tab-b2bviewer.html',
            controller: 'B2bviewerController'
        }
    }
})

你没有模板 tab-b2bviewer.html （或者你可能还没有包含在这里）。

您在选项卡中拼错了您的观点名称：

<!-- b2bviewer Tab -->
<ion-tab title="b2bviewr" icon-off="ion-ios-pulse" icon-on="ion-ios-pulse-strong" href="#/tab/b2bviewer">
  <ion-nav-view name="tab-b2bviewr"></ion-nav-view>
</ion-tab>

您已使用 tab-b2bviewr ，它应为 tab-b2bviewr 。

您可以检查代码here的改编。

Ionic - ion-nav-bar class =“bar-stable” - 标签未显示
