我知道互联网上有很多例子,但是我无法解决问题。
我有带有路由的路由器。我想在后台动态加载页面的一部分并替换它们。当我单击菜单中的链接时,所有页面正在重新加载,而不更新页面的一部分。
如何修改此代码以从服务器加载组件并替换页面的一部分?
对我来说,更好的是展示工作示例,我尝试思考在哪里进行更改。
我正在使用webpack
和semantic-ui-react
index.js
import React from 'react';
import ReactDOM from 'react-dom';
import Main from './pages/Main.jsx';
import Company from './pages/Company.jsx';
import Account from './pages/Account.jsx';
import Contact from './pages/Contact.jsx';
import { Router, Route, Switch, History, withRouter } from "react-router";
import { createBrowserHistory } from 'history';
import MainMenu, {VerticalSidebar} from './MainMenu.jsx';
import Footer from './Footer.jsx';
import 'semantic-ui-css/semantic.min.css';
import './style.css';
import { Sidebar, Component} from 'semantic-ui-react'
export class App extends React.Component {
state = {
dimmed: false,
visible: false,
width: 0,
height: 0,
}
handleShowClick = () => {this.setState({
visible: true,
dimmed: true
}),document.body.classList.add('hideOverflow')}
handleHideClick = () => {this.setState({
visible: false,
dimmed: false
}),document.body.classList.remove('hideOverflow')}
handleSidebarHide = () => {this.setState({
visible: false,
dimmed: false
}),document.body.classList.remove('hideOverflow')}
updateDimensions(){
document.querySelector('div.pushable div.pusher').style.minHeight = (window.innerHeight-document.querySelector('div.pushable div.footer').clientHeight-document.querySelector('div.pushable div.pusher div.menu').clientHeight)+'px';
}
componentDidMount(){
this.updateDimensions();
window.addEventListener("resize", this.updateDimensions.bind(this));
}
componentWillUnmount(){
window.removeEventListener("resize", this.updateDimensions.bind(this));
}
render(){
return (
<>
<VerticalSidebar visible={this.state.visible} handleHideClick={this.handleHideClick}/>
<Sidebar.Pushable as='div' >
<Sidebar.Pusher dimmed={this.state.dimmed} style={{width: '100%'}}>
<MainMenu handleShowClick={this.handleShowClick}/>
//I think that problem is below//////////
<Router history={createBrowserHistory()}>
<Switch>
<Route exact path="/" component={Main} />
<Route path="/companypage" component={Company} />
<Route path="/accountpage" component={Account} />
<Route path="/contactpage" component={Contact} />
</Switch>
</Router>
</Sidebar.Pusher>
<Footer/>
</Sidebar.Pushable>
</>
)
}
}
ReactDOM.render(
<App/>, document.getElementById('app')
);
MainMenu.jsx
<Menu>
<Menu.Item as='a' href="/">
<Menu.Item as='a' href="/companypage">
<Menu.Item as='a' href="/accountpage">
<Menu.Item as='a' href="/contactpage">
</Menu>

您需要将那些组件保留在要更新的交换机内。如果您不想更新这些文件,请将其保留在交换机之外。像这样的东西。
<Header />
<Switch>
<DynamicPage />
<DynamicPage2 />
</Switch>
<Footer />
希望这会有所帮助!
