Javascript 将路由器dom v.4 BrowseRouter传递函数反应到子级

我刚刚升级到React路由器v.4（和redux传奇）。但我在路由中将函数从父容器传递到子容器时遇到问题

家长：

import React, { Component } from 'react';
import { bindActionCreators } from 'redux';
import { connect } from 'react-redux';
import { BrowserRouter as Router, Route, NavLink } from 'react-router-dom';

import { fetchGalleryImages } from './business_logic/modules/gallery'

import logo from './assets/images/saga-logo.png';
import Gallery from './components/Gallery';

function mapStateToProps(state) {
    return { galleryImages: state.galleryImages };
}
function mapDispatchToProps(dispatch) {
    return { actions: bindActionCreators({ fetchGalleryImages }, dispatch) };
}

class App extends Component {
    constructor(props) {
        super(props);
        this.loadGallery = props.actions.fetchGalleryImages.bind(this);
    }

    loadGalleryHandler() {
        this.loadGallery();
    }

    render() {
        return (
            <div className="App">
                <img src={logo} className="logo" alt="logo" />
                <h1>Welcome to Redux-Saga</h1>
                <section className="content">
                    <p>This is an exersize in using react together with Redux-saga.</p>

                    <Router>
                        <div>
                            <nav className="main">
                                <NavLink activeClassName="selected" exact to="/" >Home</NavLink>
                                <NavLink activeClassName="selected" to="/gallery">Gallery</NavLink>
                            </nav>

                            <Route path="/gallery" onLoadEvent={this.loadGalleryHandler} component={Gallery} />
                        </div>
                    </Router>
                </section>
            </div>
        );
    }
}

export default connect(mapStateToProps, mapDispatchToProps)(App);

显然，

onLoadEvent=loadGalleryHandler（）

没有传递给Gallery

如何使其工作？

正如您所注意到的，传递给

的道具不会传递给您的组件。这是路线道具的确切用例

而不是这个,

<Route path="/gallery" onLoadEvent={this.loadGalleryHandler} component={Gallery} />

您可以这样做，然后将任何道具传递给您想要的组件

<Route path="/gallery" render={() => (
  <Gallery {...props} onLoadEvent={this.loadGalleryHandler} />
)} />

(
)} />

<Route path="/gallery" onLoadEvent={this.loadGalleryHandler} component={Gallery} />

<Route path="/gallery" render={() => (
  <Gallery {...props} onLoadEvent={this.loadGalleryHandler} />
)} />
