我正在创建选项卡,并在第一个选项卡中添加路由。但是,单击链接后未显示所需的页面。尽管刷新页面后,相应的页面将显示在屏幕上。任何人都可以帮助我解决这个问题,因为我为此使用了实质性的用户界面

function TabPanel(props) {
  const { children, value, index, ...other } = props;

  return (
    <Typography
      component="div"
      role="tabpanel"
      hidden={value !== index}
      id={`simple-tabpanel-${index}`}
      aria-labelledby={`simple-tab-${index}`}
      {...other}
    >
      <Box p={3}>{children}</Box>
    </Typography>
  );
}

TabPanel.propTypes = {
  children: PropTypes.node,
  index: PropTypes.any.isRequired,
  value: PropTypes.any.isRequired,
};

function a11yProps(index) {
  return {
    id: `simple-tab-${index}`,
    'aria-controls': `simple-tabpanel-${index}`,
  };
}

const useStyles = makeStyles(theme => ({
  root: {
    flexGrow: 1,
    backgroundColor: theme.palette.background.paper,
  },
}));

export default function SimpleTabs() {
  const classes = useStyles();
  const [value, setValue] = React.useState(0);

  const handleChange = (event, newValue) => {
    setValue(newValue);
  };

  return (
    <div className={classes.root}>
      <AppBar position="static">
        <Tabs value={value} onChange={handleChange} aria-label="simple tabs example">
          <Tab label="Item One" {...a11yProps(0)} />
          <Tab label="Item Two" {...a11yProps(1)} />
          <Tab label="Item Three" {...a11yProps(2)} />
        </Tabs>
      </AppBar>
          <TabPanel value={value} index={0}>
              <Router>
              <ul className="navbar-nav mr-auto"  >

                  <li><Link to={'/Text'} className="nav-link"><i class="fas fa-text-height"></i> Text </Link></li>

                  </ul>
                  <div>

                  </div>
              </Router>
      </TabPanel>
      <TabPanel value={value} index={1}>
        Item Two
      </TabPanel>
      <TabPanel value={value} index={2}>
        Item Three
      </TabPanel>
          <Router>
              <Switch>
                  <Route exact path='/Text' component={Text} />

              </Switch>
              </Router>
    </div>
  );
}

所以请告诉我应该在哪里更改或代码有什么问题。

为什么要两次声明Router组件?应该有only one Router个组件包装整个应用程序(不是在需要2+的情况下谈论特殊情况),这就是您的LinkRoute不同步的原因。尝试这样的事情:

return (
    <Router>
    <div className={classes.root}>
      <AppBar position="static">
        <Tabs value={value} onChange={handleChange} aria-label="simple tabs example">
          <Tab label="Item One" {...a11yProps(0)} />
          <Tab label="Item Two" {...a11yProps(1)} />
          <Tab label="Item Three" {...a11yProps(2)} />
        </Tabs>
      </AppBar>
          <TabPanel value={value} index={0}>
              <ul className="navbar-nav mr-auto"  >

                  <li><Link to={'/Text'} className="nav-link"><i class="fas fa-text-height"></i> Text </Link></li>

                  </ul>
                  <div>

                  </div>
      </TabPanel>
      <TabPanel value={value} index={1}>
        Item Two
      </TabPanel>
      <TabPanel value={value} index={2}>
        Item Three
      </TabPanel>
              <Switch>
                  <Route exact path='/Text' component={Text} />

              </Switch>
    </div>
   </Router>
  );
