Javascript 反应JS页眉和页脚

我正在尝试创建一个布局组件，该组件将呈现页眉和页脚。这样我以后就可以像这样使用布局了

<Layout> ... </Layout>

。。。

显然，我在页眉和页脚中使用了路由。要做到这一点，我需要使用

<Router history...
 <Route path...

---

我建议您不要将路由器组件渲染两次（我没有检查，但您可能无法）

那么，路由器组件的工作原理是：


你给路由器一个历史记录（通过历史道具），在这里你可以使用来自同一个库的browserHistory
然后，使用带有路径的路由组件定义应用程序的所有现有路由，如果浏览器url与此路径属性匹配，则定义要加载的组件

现在，在你的情况下，我建议你这样做：

app.js

import React from 'react';
import {Link} from 'react-router'
import {Navbar, NavItem} from 'react-materialize';

export default React.createClass({
  render(){
    return (
    <div>
      <Navbar brand='logo' right>
        <NavItem><Link to="/Home" activeClassName="active">Home</Link></NavItem>
        <NavItem><Link to="/Sign-In" activeClassName="active">Sign In</Link></NavItem>
        <NavItem><Link to="/Register" activeClassName="active">Register</Link></NavItem>
      </Navbar>
      {this.props.children}
    </div>
    )
  }
})

import React, {Component} from 'react';
import {Link} from 'react-router'
import {Footer} from 'react-materialize';
import '../../resource/template.css'


class RT_Footer extends Component{
  render(){
    return (
    <div>
      {this.props.children}
      <Footer copyrights="&copy; 2015 Copyright Text"
          moreLinks={
            <Link className="grey-text text-lighten-4 right" href="#!">More Links</Link>
          }
          links={
            <ul>
              <li><Link to="/About Us" className="grey-text text-lighten-3">About Us</Link></li>
              <li><Link to="/Terms & Conditions" className="grey-text text-lighten-3">Terms & Conditions</Link></li>
              <li><Link to="/Help" className="grey-text text-lighten-3">Help</Link></li>
              <li><Link to="/Contact Us" className="grey-text text-lighten-3">Contact Us</Link></li>
            </ul>
          }
          className='example'
      >
        <h5 className="white-text">Footer Content</h5>
        <p className="grey-text text-lighten-4">You can use rows and columns here to organize your footer content.</p>
      </Footer>
    </div>
    );
  }
}
export default RT_Footer;

import {Router, Route, browserHistory} from 'react-router'

class Layout extends Component {
  render(){
    return (
      <div>
      <span>
        <Router history={browserHistory}>
          <Route path="/" component={Header}>
           <Route path="/Home" component={Home}/>
           <Route path="/Sign-In" component={SignIn}/>
           <Route path="/Register" component={Register}/>
          </Route>
        </Router>
      </span>
      <span>
        <Router history={browserHistory}>
          <Route path="/" component={RT_Footer}>
           <Route path="/About Us" component={About}/>
           <Route path="/Terms & Conditions" component={TC}/>
           <Route path="/Register" component={Register}/>
          </Route>
        </Router>
      </span>
      </div>
    );
  }
}
export default Layout;

import {Router, Route, browserHistory} from 'react-router'
import Layout from './components/Layout'
// Import here all the required components used by the router such as SignIn, Register, ...

render(
    <Layout>
        <Router history={browserHistory}>
            <Route path="/" component={RT_Footer}>
            <Route path="/About Us" component={About}/>
            <Route path="/Terms & Conditions" component={TC}/>
            <Route path="/Register" component={Register}/>
           // Add as many Route components as needed
        </Router>
    </Layout>,
    document.getElementById('react-anchor')

import Header from './Header'
import Footer from './Footer'
import React, {Component} from 'react'

class Layout extends Component {
    render() {
        return (
            <div>
                <Header />
                {this.props.children}
                <Footer />
            </div>
        )
    }
}

从'react Router'导入{Router，Route，browserHistory}
从“./components/Layout”导入布局
//在此导入路由器使用的所有必需组件，如登录、注册等。。。
渲染(
//根据需要添加尽可能多的管线构件
,
document.getElementById（'react-anchor'）

然后，布局文件应如下所示：

layout.js

import React from 'react';
import {Link} from 'react-router'
import {Navbar, NavItem} from 'react-materialize';

export default React.createClass({
  render(){
    return (
    <div>
      <Navbar brand='logo' right>
        <NavItem><Link to="/Home" activeClassName="active">Home</Link></NavItem>
        <NavItem><Link to="/Sign-In" activeClassName="active">Sign In</Link></NavItem>
        <NavItem><Link to="/Register" activeClassName="active">Register</Link></NavItem>
      </Navbar>
      {this.props.children}
    </div>
    )
  }
})

import React, {Component} from 'react';
import {Link} from 'react-router'
import {Footer} from 'react-materialize';
import '../../resource/template.css'


class RT_Footer extends Component{
  render(){
    return (
    <div>
      {this.props.children}
      <Footer copyrights="&copy; 2015 Copyright Text"
          moreLinks={
            <Link className="grey-text text-lighten-4 right" href="#!">More Links</Link>
          }
          links={
            <ul>
              <li><Link to="/About Us" className="grey-text text-lighten-3">About Us</Link></li>
              <li><Link to="/Terms & Conditions" className="grey-text text-lighten-3">Terms & Conditions</Link></li>
              <li><Link to="/Help" className="grey-text text-lighten-3">Help</Link></li>
              <li><Link to="/Contact Us" className="grey-text text-lighten-3">Contact Us</Link></li>
            </ul>
          }
          className='example'
      >
        <h5 className="white-text">Footer Content</h5>
        <p className="grey-text text-lighten-4">You can use rows and columns here to organize your footer content.</p>
      </Footer>
    </div>
    );
  }
}
export default RT_Footer;

import {Router, Route, browserHistory} from 'react-router'

class Layout extends Component {
  render(){
    return (
      <div>
      <span>
        <Router history={browserHistory}>
          <Route path="/" component={Header}>
           <Route path="/Home" component={Home}/>
           <Route path="/Sign-In" component={SignIn}/>
           <Route path="/Register" component={Register}/>
          </Route>
        </Router>
      </span>
      <span>
        <Router history={browserHistory}>
          <Route path="/" component={RT_Footer}>
           <Route path="/About Us" component={About}/>
           <Route path="/Terms & Conditions" component={TC}/>
           <Route path="/Register" component={Register}/>
          </Route>
        </Router>
      </span>
      </div>
    );
  }
}
export default Layout;

import {Router, Route, browserHistory} from 'react-router'
import Layout from './components/Layout'
// Import here all the required components used by the router such as SignIn, Register, ...

render(
    <Layout>
        <Router history={browserHistory}>
            <Route path="/" component={RT_Footer}>
            <Route path="/About Us" component={About}/>
            <Route path="/Terms & Conditions" component={TC}/>
            <Route path="/Register" component={Register}/>
           // Add as many Route components as needed
        </Router>
    </Layout>,
    document.getElementById('react-anchor')

import Header from './Header'
import Footer from './Footer'
import React, {Component} from 'react'

class Layout extends Component {
    render() {
        return (
            <div>
                <Header />
                {this.props.children}
                <Footer />
            </div>
        )
    }
}

从“./Header”导入头
从“./Footer”导入页脚
从“React”导入React，{Component}
类布局扩展组件{
render（）{
返回(
{this.props.children}
)
}
}

在页眉和页脚组件中，呈现您想要的任何内容，以提供链接来加载所请求的组件，您可以从react router或库提供的其他方式使用该组件（请参阅其文档）

编辑：

注意路线路径，如“条款与条件”可能不是有效路径
，但尽管使用了@Quentin，它仍然不起作用，我尝试使用此答案并收到以下错误：
未捕获错误：您不应该在
之外使用它为什么会发生？代码是相同的，只是h在任何组件（包括）中都需要嵌套。也许试试…@Quentin这很有帮助。对我来说很有用。我在这里面临一个问题。只有当用户登录时，我才能显示页眉和页脚。我可以访问令牌{this.props.children}，但它在页眉或页脚中不可访问。你能帮我解决这个问题吗？
