我最近开始学习 React.js，现在正在尝试使用动画/过渡。我正在使用 React Router 并尝试使用 ReactCSSTransitionGroup 实现页面之间非常简单的转换。当我加载/刷新页面时它起作用，但当我通过导航链接从一个页面转到另一个页面时它不起作用。尝试使用下一个代码使页面淡入，但它不起作用:
package.json
{
"name": "reactapp",
"version": "1.0.0",
"description": "",
"main": "main.js",
"dependencies": {
"babel-core": "^6.9.1",
"babel-preset-react": "^6.5.0",
"babel-loader": "^6.2.4",
"babel-preset-es2015": "^6.9.0",
"react": "^15.1.0",
"react-dom": "^15.1.0",
"webpack": "^1.13.1",
"webpack-dev-server": "^1.14.1"
},
"devDependencies": {},
"scripts": {
"start": "webpack-dev-server --inline --content-base . --history-api-fallback"
},
"author": "",
"license": "ISC"
}
index.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>React App</title>
<link rel="stylesheet" href="/app.css">
</head>
<body>
<div id="app"></div>
<script src="/index.js"></script>
</body>
</html>
index.js
import React from 'react';
import ReactDOM from 'react-dom';
import { Router, Route, Link, browserHistory, IndexRoute } from 'react-router'
import ReactCSSTransitionGroup from 'react-addons-css-transition-group';
class App extends React.Component {
render() {
return (
<div>
<ul>
<Link to="/home">Home</Link>
<Link to="/about">About</Link>
<Link to="/contact">Contact</Link>
</ul>
<ReactCSSTransitionGroup transitionName="example" transitionAppear={true} transitionAppearTimeout={500}>
{this.props.children}
</ReactCSSTransitionGroup>
</div>
)
}
}
export default App;
class Home extends React.Component {
render() {
return (
<div>
<h1>Home...</h1>
</div>
)
}
}
export default Home;
class About extends React.Component {
render() {
return (
<div>
<h1>About...</h1>
</div>
)
}
}
export default About;
class Contact extends React.Component {
render() {
return (
<div>
<h1>Contact...</h1>
</div>
)
}
}
export default Contact;
ReactDOM.render((
<Router history={browserHistory}>
<Route path = "/" component = {App}>
<IndexRoute component = {Home} />
<Route path = "home" component = {Home} />
<Route path = "about" component = {About} />
<Route path = "contact" component = {Contact} />
</Route>
</Router>
), document.getElementById('app'))
app.css
.example-appear {
opacity: 0.01;
}
.example-appear.example-appear-active {
opacity: 1;
transition: opacity .5s ease-in;
}
有什么想法可以让这项工作发挥作用吗？
谢谢!

您必须克隆组件，将子组件作为 props 传递给它，而不是仅仅渲染 this.props.children。然后 React-router 使用该键进行导航。
<ReactCSSTransitionGroup
transitionName="example"
transitionAppear={true}
transitionAppearTimeout={500}
>
{React.cloneElement(this.props.children, { key: this.props.location.pathname })}
</ReactCSSTransitionGroup>
