Material-UI的Tabs与react路由器4集成？

Question

新的反应转子语法使用该Link组件在路径上移动.但是如何与它结合materiaul-ui？

就我而言,我使用制表符作为主导航系统,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,即孩子Tabs必须是一个Tab组件.有什么办法可以继续？如何管理选项卡的isActive道具？

另一个没有处理程序或HOC的解决方案(https://codesandbox.io/s/l4yo482pll),只有纯粹的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);

我的讲师帮助我使用React Router 4.0的withRouter来包装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就可以了.

您从 material-ui 中看到的错误是因为它希望将<Tab>组件呈现为组件的直接子级<Tabs>。

现在，我发现了一种将链接集成到<Tabs>组件中而不会丢失样式的方法：

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“活动”属性，您可以value在<Tabs>组件中使用该属性，并且您还需要value为每个选项卡设置一个属性，因此当两个属性匹配时，它会将活动样式应用于该选项卡。
