Material-UI 的选项卡与反应路由器 4 集成?
Material-UI's Tabs integration with react router 4?
新的 react-router 语法使用 Link
组件在路由中移动。但是这怎么能和material-ui
整合呢?
在我的例子中,我使用标签作为主要导航系统,所以理论上我应该有这样的东西:
const TabLink = ({ onClick, href, isActive, label }) =>
<Tab
label={label}
onActive={onClick}
/>
export default class NavBar extends React.Component {
render () {
return (
<Tabs>
<Link to="/">{params => <TabLink label="Home" {...params}/>}</Link>
<Link to="/shop">{params => <TabLink label="shop" {...params}/>}</Link>
<Link to="/gallery">{params => <TabLink label="gallery" {...params}/>}</Link>
</Tabs>
)
}
}
但是当它呈现时,material-ui 会抛出一个错误,即 Tabs
的子组件必须是 Tab
组件。下一步的方法是什么?如何管理选项卡的 isActive
属性?
提前致谢
您可以使用 browserHistory
代替 React-Router Link
组件
import { browserHistory } from 'react-router'
// Go to /some/path.
onClick(label) {
browserHistory.push('/${label}');
}
// Example for Go back
//browserHistory.goBack()
<Tabs>
<Tab
label={label}
onActive={() => onClick(label)}
/>
</Tabs>
如您所见,您可以简单地 push()
您的目标 browserHistory
您在 material-ui 中看到的错误是因为它希望将 <Tab>
组件呈现为 <Tabs>
组件的直接子组件。
现在,这是我发现的一种将 link 集成到 <Tabs>
组件中而不丢失样式的方法:
import React, {Component} from 'react';
import {Tabs, Tab} from 'material-ui/Tabs';
import {Link} from 'react-router-dom';
export default class MyComponent extends Component {
render() {
const {location} = this.props;
const {pathname} = location;
return (
<Tabs value={pathname}>
<Tab label="First tab" containerElement={<Link to="/my-firs-tab-view" />} value="/my-firs-tab-view">
{/* insert your component to be rendered inside the tab here */}
</Tab>
<Tab label="Second tab" containerElement={<Link to="/my-second-tab-view" />} value="/my-second-tab-view">
{/* insert your component to be rendered inside the tab here */}
</Tab>
</Tabs>
);
}
}
要管理选项卡的 'active' 属性,您可以使用 <Tabs>
组件中的 value
属性 并且您还需要拥有每个选项卡的 value
属性,因此当两个属性匹配时,它会将活动样式应用于该选项卡。
我的导师帮助我使用 React Router 4.0 的 withRouter 包装 Tabs 组件以启用历史方法,如下所示:
import React, {Component} from "react";
import {Tabs, Tab} from 'material-ui';
import { withRouter } from "react-router-dom";
import Home from "./Home";
import Portfolio from "./Portfolio";
class NavTabs extends Component {
handleCallToRouter = (value) => {
this.props.history.push(value);
}
render () {
return (
<Tabs
value={this.props.history.location.pathname}
onChange={this.handleCallToRouter}
>
<Tab
label="Home"
value="/"
>
<div>
<Home />
</div>
</Tab>
<Tab
label="Portfolio"
value="/portfolio"
>
<div>
<Portfolio />
</div>
</Tab>
</Tabs>
)
}
}
export default withRouter(NavTabs)
只需将 BrowserRouter 添加到 index.js 即可。
正如@gkatchmar 所说,您可以使用 withRouter
高阶组件,但您也可以使用 context API
。由于@gkatchmar 已经显示了 withRouter,所以我将只显示 context API
。请记住,这是一个实验性的 API.
import React, {Component} from "react";
import {Tabs, Tab} from 'material-ui';
import * as PropTypes from "prop-types";
export class NavTabs extends Component {
constructor(props) {
super(props);
}
static contextTypes = {
router: PropTypes.object
}
handleChange = (event: any , value: any) => {
this.context.router.history.push(value);
};
render () {
return (
<Tabs
value={this.context.router.history.location.pathname}
onChange={this.handleChange}
>
<Tab
label="Home"
value="/"
>
<div>
<Home />
</div>
</Tab>
<Tab
label="Portfolio"
value="/portfolio"
>
<div>
<Portfolio />
</div>
</Tab>
</Tabs>
)
}
}
这是另一个解决方案,使用 Material 1.0 的测试版并添加浏览器 Back/Forward:
import React from 'react';
import PropTypes from 'prop-types';
import { withStyles } from 'material-ui/styles';
import AppBar from 'material-ui/AppBar';
import Tabs, { Tab } from 'material-ui/Tabs';
import { withRouter } from "react-router-dom";
import Home from "./Home";
import Portfolio from "./Portfolio";
function TabContainer(props) {
return <div style={{ padding: 20 }}>{props.children}</div>;
}
const styles = theme => ({
root: {
flexGrow: 1,
width: '100%',
marginTop: theme.spacing.unit * 3,
backgroundColor: theme.palette.background.paper,
},
});
class NavTabs extends React.Component {
state = {
value: "/",
};
componentDidMount() {
window.onpopstate = ()=> {
this.setState({
value: this.props.history.location.pathname
});
}
}
handleChange = (event, value) => {
this.setState({ value });
this.props.history.push(value);
};
render() {
const { classes } = this.props;
const { value } = this.state;
return (
<div className={classes.root}>
<AppBar position="static" color="default">
<Tabs
value={value}
onChange={this.handleChange}
scrollable
scrollButtons="on"
indicatorColor="primary"
textColor="primary"
>
<Tab label="Home" value = "/" />
<Tab label="Portfolio" value = "/portfolio"/>
</Tabs>
</AppBar>
{value === "/" && <TabContainer>{<Home />}</TabContainer>}
{value === "/portfolio" && <TabContainer>{<Portfolio />}</TabContainer>}
</div>
);
}
}
NavTabs.propTypes = {
classes: PropTypes.object.isRequired,
};
export default withRouter(withStyles(styles)(NavTabs));
另一种解决方案 (https://codesandbox.io/s/l4yo482pll) 没有处理程序也没有 HOC,只有纯 react-router 和 material-ui 组件:
import React, { Fragment } from "react";
import ReactDOM from "react-dom";
import Tabs from "@material-ui/core/Tabs";
import Tab from "@material-ui/core/Tab";
import { Switch, Route, Link, BrowserRouter, Redirect } from "react-router-dom";
function App() {
const allTabs = ['/', '/tab2', '/tab3'];
return (
<BrowserRouter>
<div className="App">
<Route
path="/"
render={({ location }) => (
<Fragment>
<Tabs value={location.pathname}>
<Tab label="Item One" value="/" component={Link} to={allTabs[0]} />
<Tab label="Item Two" value="/tab2" component={Link} to={allTabs[1]} />
<Tab
value="/tab3"
label="Item Three"
component={Link}
to={allTabs[2]}
/>
</Tabs>
<Switch>
<Route path={allTabs[1]} render={() => <div>Tab 2</div>} />
<Route path={allTabs[2]} render={() => <div>Tab 3</div>} />
<Route path={allTabs[0]} render={() => <div>Tab 1</div>} />
</Switch>
</Fragment>
)}
/>
</div>
</BrowserRouter>
);
}
const rootElement = document.getElementById("root");
ReactDOM.render(<App />, rootElement);
我在我的应用程序中以这种方式工作:
import React, {useEffect, useRef} from 'react';
import PropTypes from 'prop-types';
import {makeStyles} from '@material-ui/core/styles';
import AppBar from '@material-ui/core/AppBar';
import Tabs from '@material-ui/core/Tabs';
import Tab from '@material-ui/core/Tab';
import Typography from '@material-ui/core/Typography';
import Box from '@material-ui/core/Box';
import Container from "@material-ui/core/Container";
import {Link} from "react-router-dom";
import MenuIcon from "@material-ui/icons/Menu";
import VideoCallIcon from "@material-ui/icons/VideoCall";
const docStyles = makeStyles(theme => ({
root: {
display: 'flex',
'& > * + *': {
marginLeft: theme.spacing(2),
},
},
appBarRoot: {
flexGrow: 1,
},
headline: {
marginTop: theme.spacing(2),
},
bodyCopy: {
marginTop: theme.spacing(1),
fontSize: '1.2rem',
},
tabContents: {
margin: theme.spacing(3),
},
}));
function TabPanel(props) {
const {children, value, index, classes, ...other} = props;
return (
<div
role="tabpanel"
hidden={value !== index}
id={`simple-tabpanel-${index}`}
aria-labelledby={`simple-tab-${index}`}
{...other}
>
{value === index && (
<Container>
<Box className={classes.tabContents}>
{children}
</Box>
</Container>
)}
</div>
);
}
function a11yProps(index) {
return {
id: `simple-tab-${index}`,
'aria-controls': `simple-tabpanel-${index}`,
};
}
function TabOneContents(props) {
const {classes} = props;
return (
<>
<Typography variant="h4" component={'h1'} className={classes.headline}>
Headline 1
</Typography>
<Typography variant="body1" className={classes.bodyCopy}>
Body Copy 1
</Typography>
</>
)
}
function TabTwoContents(props) {
const {classes} = props;
const nurseOnboardingPath = '/navigator/onboarding/' + Meteor.userId() + '/1';
return (
<>
<Typography variant="h4" component={'h1'} className={classes.headline}>
Headline 2
</Typography>
<Typography variant="body1" className={classes.bodyCopy}>
Body Copy 2
</Typography>
</>
)
}
export default function MUITabPlusReactRouterDemo(props) {
const {history, match} = props;
const propsForDynamicClasses = {};
const classes = docStyles(propsForDynamicClasses);
const [value, setValue] = React.useState(history.location.pathname.includes('/tab_2') ? 1 : 0);
const handleChange = (event, newValue) => {
setValue(newValue);
const pathName = '/' + (value == 0 ? 'tab_1' : 'tab_2');
history.push(pathName);
};
return (
<div className={classes.appBarRoot}>
<AppBar position="static" color="transparent">
<Tabs value={value} onChange={handleChange} aria-label="How It Works" textColor="primary">
<Tab label="Tab 1" {...a11yProps(0)} />
<Tab label="Tab 2" {...a11yProps(1)} />
</Tabs>
</AppBar>
<TabPanel value={value} index={0} classes={classes}>
<TabOneContents classes={classes}/>
</TabPanel>
<TabPanel value={value} index={1} classes={classes}>
<TabTwoContents classes={classes}/>
</TabPanel>
</div>
);
}
...在 React Router 中:
[.....]
<Route exact path="/tab_1"
render={(routeProps) =>
<MUITabPlusReactRouterDemo history={routeProps.history}
/>
}/>
<Route exact path="/tab_2"
render={(routeProps) =>
<MUITabPlusReactRouterDemo history={routeProps.history} />
}/>
[.....]
<BrowserRouter>
<div className={classes.root}>
<AppBar position="static" color="default">
<Tabs
value={this.state.value}
onChange={this.handleChange}
indicatorColor="primary"
textColor="primary"
fullWidth
>
<Tab label="Item One" component={Link} to="/one" />
<Tab label="Item Two" component={Link} to="/two" />
</Tabs>
</AppBar>
<Switch>
<Route path="/one" component={PageShell(ItemOne)} />
<Route path="/two" component={PageShell(ItemTwo)} />
</Switch>
</div>
这是一个使用 useLocation
挂钩的简单解决方案。不需要状态。尽管 React 路由器 v5。
import { Tab, Tabs } from '@material-ui/core';
import { matchPath, NavLink, useLocation } from 'react-router-dom';
const navItems = [
{
id: 'one',
path: '/one',
text: 'One',
},
{
id: 'two',
path: '/two',
text: 'Two',
},
{
id: 'three',
path: '/three',
text: 'Three',
},
];
export default function Navigation() {
const { pathname } = useLocation();
const activeItem = navItems.find((item) => !!matchPath(pathname, { path: item.path }));
return (
<Tabs value={activeItem?.id}>
{navItems.map((item) => (
<Tab key={item.id} value={item.id} label={item.text} component={NavLink} to={item.path} />
))}
</Tabs>
);
}
基于 Tab 高亮的解决方案,基于 Typescript 并且适用于 react-route v5:
说明:<Tab/>
在这里用作 React 路由器的 link。 <Tab/> to={'/all-event'}
和 value={'/all-event'}
中的值应该相同,以便 highlgiht
import { Container, makeStyles, Tab, Tabs } from '@material-ui/core';
import React from 'react';
import {
Link,
Route,
Switch,
useLocation,
Redirect,
} from 'react-router-dom';
import AllEvents from './components/AllEvents';
import UserEventsDataTable from './components/UserEventsDataTable';
const useStyles = makeStyles(() => ({
container: {
display: 'flex',
justifyContent: 'center',
},
}));
function App() {
const classes = useStyles();
const location = useLocation();
return (
<>
<Container className={classes.container}>
<Tabs value={location.pathname}>
<Tab
label='All Event'
component={Link}
to={`/all-event`}
value={`/all-event`}
/>
<Tab
label='User Event'
component={Link}
to={`/user-event`}
value={`/user-event`}
/>
</Tabs>
</Container>
<Switch>
<Route path={`/all-event`}>
<AllEvents />
</Route>
<Route path={`/user-event`}>
<UserEventsDataTable />
</Route>
<Route path={`/`}>
<Redirect from='/' to='/all-event' />
</Route>
</Switch>
</>
);
}
export default App;
我创建了这个挂钩来帮助控制选项卡并生成从位置 URL.
捕获的默认值
const useTabValue = (array, mainPath = "/") => {
const history = useHistory();
const { pathname } = useLocation();
const [value, setValue] = useState(0);
const pathArray = pathname.split("/");
function handleChange(_, nextEvent) {
setValue(nextEvent);
history.push(`${mainPath}/${array[nextEvent]}`);
}
const findDefaultValue = useCallback(() => {
return array.forEach((el) => {
if (pathArray.indexOf(el) > 0) {
setValue(array.indexOf(el));
return;
}
});
}, [pathArray, array]);
useEffect(() => {
findDefaultValue();
}, [findDefaultValue]);
return {
handleChange,
value,
};
};
然后我就这样用了:
const NavigationBar = () => {
const classes = useStyles();
const allTabs = useMemo(() => ["home", "search"]);
const { handleChange, value } = useTabValue(allTabs, "/dashboard");
return (
<div className={classes.navBarContainer}>
<Tabs
centered
value={value}
variant="fullWidth"
onChange={handleChange}
className={classes.navBar}
>
<Tab color="textPrimary" icon={<HomeIcon />} />
<Tab color="textPrimary" icon={<ExploreIcon />} />
</Tabs>
</div>
);
};
我以一种更简单的方式解决了这个问题(我很惊讶它的效果如此之好——也许还有一个我还没有发现的问题)。我正在使用 Router 6 和 React 17(我知道这些包较新)。
无论如何,我只是在 handleChange 函数中使用了 useNavigate 挂钩。因此,现在不需要 Switch 并且代码变得更加简单。见下文:
let navigate = useNavigate();
const [selection, setSelection] = useState();
const handleChange = (event, newValue) => {
setSelection(newValue);
navigate(`${newValue}`);
}
return (
<Tabs value={selection} onChange={handleChange}>
<Tab label="Products" value="products" />
<Tab label="Customers" value="customers" />
<Tab label="Invoices" value="invoices" />
</Tabs>
);
}
handleChange 函数更新 'selection',它控制选项卡的显示,并导航到正确的路径。
如果您在 React space 中的某处设置组件,并正确设置 :style 路由(如 React Router 所述:https://reactrouter.com/docs/en/v6/getting-started/overview),您还可以控制页面的哪个区域显示内容呈现。希望对大家有所帮助!

这是一个使用 useLocation
挂钩的简单解决方案。不需要状态。尽管 React 路由器 v5。
import { Tab, Tabs } from '@material-ui/core';
import { matchPath, NavLink, useLocation } from 'react-router-dom';
const navItems = [
{
id: 'one',
path: '/one',
text: 'One',
},
{
id: 'two',
path: '/two',
text: 'Two',
},
{
id: 'three',
path: '/three',
text: 'Three',
},
];
export default function Navigation() {
const { pathname } = useLocation();
const activeItem = navItems.find((item) => !!matchPath(pathname, { path: item.path }));
return (
<Tabs value={activeItem?.id}>
{navItems.map((item) => (
<Tab key={item.id} value={item.id} label={item.text} component={NavLink} to={item.path} />
))}
</Tabs>
);
}
基于 Tab 高亮的解决方案,基于 Typescript 并且适用于 react-route v5:
说明:<Tab/>
在这里用作 React 路由器的 link。 <Tab/> to={'/all-event'}
和 value={'/all-event'}
中的值应该相同,以便 highlgiht
import { Container, makeStyles, Tab, Tabs } from '@material-ui/core';
import React from 'react';
import {
Link,
Route,
Switch,
useLocation,
Redirect,
} from 'react-router-dom';
import AllEvents from './components/AllEvents';
import UserEventsDataTable from './components/UserEventsDataTable';
const useStyles = makeStyles(() => ({
container: {
display: 'flex',
justifyContent: 'center',
},
}));
function App() {
const classes = useStyles();
const location = useLocation();
return (
<>
<Container className={classes.container}>
<Tabs value={location.pathname}>
<Tab
label='All Event'
component={Link}
to={`/all-event`}
value={`/all-event`}
/>
<Tab
label='User Event'
component={Link}
to={`/user-event`}
value={`/user-event`}
/>
</Tabs>
</Container>
<Switch>
<Route path={`/all-event`}>
<AllEvents />
</Route>
<Route path={`/user-event`}>
<UserEventsDataTable />
</Route>
<Route path={`/`}>
<Redirect from='/' to='/all-event' />
</Route>
</Switch>
</>
);
}
export default App;
我创建了这个挂钩来帮助控制选项卡并生成从位置 URL.
捕获的默认值const useTabValue = (array, mainPath = "/") => {
const history = useHistory();
const { pathname } = useLocation();
const [value, setValue] = useState(0);
const pathArray = pathname.split("/");
function handleChange(_, nextEvent) {
setValue(nextEvent);
history.push(`${mainPath}/${array[nextEvent]}`);
}
const findDefaultValue = useCallback(() => {
return array.forEach((el) => {
if (pathArray.indexOf(el) > 0) {
setValue(array.indexOf(el));
return;
}
});
}, [pathArray, array]);
useEffect(() => {
findDefaultValue();
}, [findDefaultValue]);
return {
handleChange,
value,
};
};
然后我就这样用了:
const NavigationBar = () => {
const classes = useStyles();
const allTabs = useMemo(() => ["home", "search"]);
const { handleChange, value } = useTabValue(allTabs, "/dashboard");
return (
<div className={classes.navBarContainer}>
<Tabs
centered
value={value}
variant="fullWidth"
onChange={handleChange}
className={classes.navBar}
>
<Tab color="textPrimary" icon={<HomeIcon />} />
<Tab color="textPrimary" icon={<ExploreIcon />} />
</Tabs>
</div>
);
};
我以一种更简单的方式解决了这个问题(我很惊讶它的效果如此之好——也许还有一个我还没有发现的问题)。我正在使用 Router 6 和 React 17(我知道这些包较新)。 无论如何,我只是在 handleChange 函数中使用了 useNavigate 挂钩。因此,现在不需要 Switch 并且代码变得更加简单。见下文:
let navigate = useNavigate();
const [selection, setSelection] = useState();
const handleChange = (event, newValue) => {
setSelection(newValue);
navigate(`${newValue}`);
}
return (
<Tabs value={selection} onChange={handleChange}>
<Tab label="Products" value="products" />
<Tab label="Customers" value="customers" />
<Tab label="Invoices" value="invoices" />
</Tabs>
);
}
handleChange 函数更新 'selection',它控制选项卡的显示,并导航到正确的路径。 如果您在 React space 中的某处设置组件,并正确设置 :style 路由(如 React Router 所述:https://reactrouter.com/docs/en/v6/getting-started/overview),您还可以控制页面的哪个区域显示内容呈现。希望对大家有所帮助!
