ion-tab
选项卡组件是 tabs 的子组件。每个选项卡都可以包含应用或单个视图的顶层导航堆栈。一个应用可以有许多选项卡，所有选项卡都有自己独立的导航。
¥The tab component is a child component of tabs. Each tab can contain a top level navigation stack for an app or a single view. An app can have many tabs, all with their own independent navigation.
注意：该组件只能与普通 JavaScript 项目一起使用。对于 Angular、React 和 Vue 应用，你不需要使用 ion-tab 来声明选项卡组件。
¥Note: This component should only be used with vanilla JavaScript projects. For Angular, React, and Vue apps you do not need to use ion-tab to declare your tab components.
有关配置选项卡的更多详细信息，请参阅 选项卡文档。
¥See the tabs documentation for more details on configuring tabs.
