Question

我正在使用带有react-onsenui绑定的React和Onsen UI构建PWA。我尝试让Tabbar适应Onsen UI网站上显示的官方示例。目前，我的代码如下所示（非常简单）：

import React, { Component } from 'react';
import { Page, Tabbar, Tab } from 'react-onsenui';

import 'onsenui/css/onsenui.css';
import 'onsenui/css/onsen-css-components.css';

import ScreenOne from './screenOne';
import ScreenTwo from './screenTwo';

class App extends Component {

  state = {
    index: 0,
  }

  render() {
    return (
      <Page>
        <Tabbar
          onPreChange={({index}) => this.setState({index})}
          onPostChange={() => console.log('postChange')}
          onReactive={() => console.log('postChange')}
          position='bottom'
          index={this.state.index}
          renderTabs={(activeIndex, tabbar) => [
            {
              content: <ScreenOne key="Home" title="Home" active={activeIndex === 0} tabbar={tabbar} />,
              tab: <Tab key="Home" label="Home" icon="md-home" />
            },
            {
              content: <ScreenTwo key="Settings" title="Settings" active={activeIndex === 1} tabbar={tabbar} />,
              tab: <Tab key="Settings"  label="Settings" icon="md-settings" />
            }]
          }
        />
      </Page>
    );
  }
}

export default App;

但是它不起作用。我可以单击一次选项卡，仅此而已。控制台向我抛出错误。

在初始页面加载

Uncaught TypeError: el._show is not a function
    at onsenui.js:31327
    at run (setImmediate.js:48)
    at runIfPresent (setImmediate.js:83)
    at onGlobalMessage (setImmediate.js:125)

在选项卡上单击

onsenui.js:31057 Uncaught (in promise) TypeError: prevTab.pageElement._hide is not a function
    at HTMLElement._onPreChange (onsenui.js:31057)
    at Swiper._changeTo (onsenui.js:15695)
    at Swiper.setActiveIndex (onsenui.js:15479)
    at onsenui.js:31233

此刻我完全被困住了。谢谢。

您可以发布ScreenOne和ScreenTwo组件吗？检查这两个组件是否由'Page'标签包裹

为什么Onsen UI会向我抛出错误？
