我正在开发一个简单的 React/Redux/Rails 项目,但在加载表单时遇到问题。我设置了一个路由器,用于保存 App.js 页面上的路由
import React, { Component } from 'react';
import { BrowserRouter as Router, Route, Switch } from 'react-router-dom'
import '../App.css';
import Navbar from '../components/Navbar'
import Home from '../components/Home'
import Games from './Games'
import GamesShow from './GamesShow';
import GameForm from './GameForm';
class App extends Component {
render() {
return (
<Router>
<div>
<Navbar />
<Switch>
<Route exact path = '/' component={Home} />
<Route exact path = '/games' component={Games} />
<Route exact path = '/games/:id' component={GamesShow} />
<Route exact path = '/games/new' component={GameForm} />
</Switch>
</div>
</Router>
);
}
}
export default App;
另一个页面上有一个链接到/games/new。
<Link to="/games/new" exact>Add a new Game</Link>
页面在 url 下加载,但除导航栏组件外,页面是黑色的。我应该提到的是,我什至还没有尝试加载表单,只是一些示例文本。我正在导入所有内容,因此我知道我的导入/导出不是问题。
import React, { Component } from 'react';
class GameForm extends Component {
render() {
return(
<div>
Add a new game to the List
<form onSubmit={this.handleOnSubmit}>
<div>
<label htmlFor="name">Name:</label>
</div>
</form>
</div>
)
}
}
export default GameForm
当我从/games/new 中删除 new 并注释掉原始游戏路径时,事情变得很奇怪,然后它会加载 url games 下的 GameForm 组件,但是当我添加/new 回来时,它停止工作。现在我认为这涵盖了所有内容,但这是我的 index.js 以防万一。
import React from 'react';
import ReactDOM from 'react-dom';
import './index.css';
import App from './containers/App';
import * as serviceWorker from './serviceWorker';
import {Provider} from 'react-redux'
import store from './store'
ReactDOM.render(
<Provider store={store}>
<App />
</Provider>,
document.getElementById('root')
)
serviceWorker.unregister();
最佳答案
您需要将 '/games/new'
移至 '/games/:id'
像这样:
<Switch>
<Route exact path = '/' component={Home} />
<Route exact path = '/games' component={Games} />
<Route exact path = '/games/new' component={GameForm} />
<Route exact path = '/games/:id' component={GamesShow} />
</Switch>
它需要出现在动态路径之前...
关于javascript - (ReactJS + Redux) 当/new 添加到 url 时,表单未加载,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/53974234/
