材质UI抽屉选择如何路线?

我正在尝试使用Material UI React抽屉,但对如何实现选择感到困惑,以便对组件进行更改。例如,我有一个名为Get Videos的选择,它应该调用我的组件,该组件对S3执行AXIOS调用以获取存储桶中的文件。

如何在我的选择中切换组件?我应该使用路线还是应该将组件的状态设置为"活动"?任何帮助将不胜感激..

一些代码

handleClick(event) {
  ????
}

render() {
    return (
        <div>
            <ListItem button>
                <ListItemIcon>
                    <ScheduleIcon/>
                </ListItemIcon>
                <ListItemText primary="Scheduler" onClick={this.handleClick.bind(this)}/>
            </ListItem>
            <ListItem button onClick={this.handleClick()}>
                <ListItemIcon>
                    <ViewListIcon/>
                </ListItemIcon>
                <ListItemText primary="Watch Saved Recordings"/>
            </ListItem>
        </div>
    );
}

假设您知道如何使用react-router-dom。如果不使用this链接找到一个好的指南。

以下是使用侧边栏进行反应路由的示例:

import React, { Component } from 'react';
import { ListItemIcon, ListItemText, Divider, IconButton, MenuList, MenuItem, Drawer } from '@material-ui/core';
import { Link, withRouter } from 'react-router-dom';
import { withStyles } from '@material-ui/core/styles';
import PropTypes from 'prop-types';

import routes from '../routes/routes';

export class Sidebar extends Component {
  constructor(props) {
    super(props);

    this.activeRoute = this.activeRoute.bind(this);
  }

  activeRoute(routeName) {
    return this.props.location.pathname.indexOf(routeName) > -1 ? true : false;
  }

  render() {
    const { classes, theme } = this.props;
    return (
      <div>
        <Drawer
          variant="permanent"
        >
          <MenuList>
            {routes.map((prop, key) => {
              return (
                <Link to={prop.path} style={{ textDecoration: 'none' }} key={key}>
                  <MenuItem selected={this.activeRoute(prop.path)}>
                    <ListItemIcon>
                      <prop.icon />
                    </ListItemIcon>
                    <ListItemText primary={prop.sidebarName} />
                  </MenuItem>
                </Link>
              );
            })}
          </MenuList>
        </Drawer>
      </div>
    );
  }
}

export default withRouter(Sidebar);

并且您的路由器文件应如下所示:

import { Home, ContentPaste, Notifications, AccountCircle } from '@material-ui/icons';
import HomePage from '../pages/Home/HomePage';
import ProfilePage from '../pages/Profile/ProfilePage';

const Routes = [
  {
    path: '/dashboard/home',
    sidebarName: 'Home',
    navbarName: 'Home',
    icon: Home,
    component: HomePage
  },
  {
    path: '/dashboard/profile',
    sidebarName: 'Profile',
    navbarName: 'Profile',
    icon: AccountCircle,
    component: ProfilePage
  }
];

export default Routes;

使用activeRoute,您可以突出显示当前路线

此外,您可以使用useLocation使用钩子

 import { useLocation } from "react-router-dom";

然后您可以创建相同的行为

      const [path, setPath] = useState("");

      let location = useLocation();

      useEffect(() => {
        setPath(location.pathname);
        console.log(location.pathname)
      }, [location,setPath]);

  const activetRoute = route => {
      console.log(route , path);
    return route === path;
  }

<List>
        {routers.map((item, key) => (
          <ListItem
            key={key}
            button
            component={Link}
            to={item.path}
            selected={activetRoute(item.path)}
          >
            <ListItemIcon>
              <item.icon />
            </ListItemIcon>
            <ListItemText primary={item.sidebarName} />
          </ListItem>
        ))}
      </List>
