javascript - 将参数传递给 React Router 中的 React 元素

Question

我创建了一个名为 Jobscard 的元素，它将 jobsList 作为参数。我还尝试使用 react-router 将此 jobsCard 设置为路由器。

我调查了这个问题，他们似乎在网络上没有类似的问题，所有解决方案和指南都使用 react 组件，但这不适用于 react 元素。这可能吗？

import React from 'react';
import { projectList } from './projectList';
import JobsCard from './JobsCard';
import { jobsList } from './jobsList';
import CardList from './CardList';
import Ham from './hamburger';
import { Route, Switch } from 'react-router-dom';
import { BrowserRouter } from 'react-router-dom';
import jobsList from './jobsList'

const App = () => {
    return(

            <div className='blue1  center'>

                    <BrowserRouter>
                        <Ham />

                        <Switch>
                            <Route exact path="/" render{props => <JobsCard jobsList={jobsList}> </JobsCard> }/>

                           <Route path="/projects" component={<CardList projectList={projectList}/>}/> 
                        </Switch>
                    </BrowserRouter>


            </div>

  )
}

export default App;

JobsCard 元素是

import React from 'react';
import Job from './Job.js'

const JobsCard = ({jobsList}) => {
    const cardDraw = jobsList.map((proj, i) => {
        return <Job key={i} title={jobsList[i].title} 
        website={jobsList[i].website} description={jobsList[i].description} 
        logo={jobsList[i].logo} company={jobsList[i].company} years={jobsList[i].years}/>
    })
    return (
        <div className=" cf justify-center ma3">
                {cardDraw}


        </div>
    );
}

export default JobsCard;

jobsList 看起来像这样

import energyxchain from ''
export const jobsList = [
    {   title: '',
        website: '',
        description: '',
        logo: ,
        company: '',
        years: '2018-2019'
    },
    {
        title: '',
        company: '',
        website: '',
        logo: '',
        description: '',
        years: '2017-2018'
    }];

我希望 jobsCard 成为一条路线。

Answer 1

来自 route rendering props :

render, which takes an inline function, should only be used when you have to pass in-scope variables to the component you want to render.

You should not use the component prop with an inline function to pass in-scope variables because you will get undesired component unmounts/remounts.

所以你的路线应该是 ff:

使用 component 属性(不应传递变量):

<Route
  exact path="/"
  component={JobsCard}
/>

使用 render 属性:

<Route
  exact path="/"
  render={routeProps => (<JobsCard {...routeProps} jobsList={jobsList} />)}
/>

通常，您应该将导航与内部数据管理分开(使用 redux connect)。
