我有 ReactCSSTransitionGroup 工作正常（我认为），新安装的组件逐渐消失在它的所有荣耀中。
问题是被替换的组件突然消失了，这对我来说是个问题，因为最终我希望我的组件能够进出视口...
我似乎没有看到任何方式告诉离开的组件如何优雅地消失。
我错过了什么还是 ReactCSSTransitionGroup 只能为传入的组件设置动画？
更新
下面的代码：
import React from "react";
import ReactDOM from "react-dom";
import { Router, Route, IndexRoute, hashHistory, Link } from "react-router";
import ReactCSSTransitionGroup from "react-addons-css-transition-group";
class PageOne extends React.Component {
render() {
return (
<ReactCSSTransitionGroup transitionName="example" transitionAppear={true} transitionAppearTimeout={500} transitionEnterTimeout={500} transitionLeaveTimeout={500}>
<div>
HI FROM PAGE ONE<br />
<br />
<Link to="two">Take me to Page Two</Link>
</div>
</ReactCSSTransitionGroup>
);
}
}
class PageTwo extends React.Component {
render() {
return (
<ReactCSSTransitionGroup transitionName="example" transitionAppear={true} transitionAppearTimeout={500} transitionEnterTimeout={500} transitionLeaveTimeout={500}>
<div>
HELLO FROM PAGE TWO<br />
<br />
<Link to="/">Go back to Page One</Link>
</div>
</ReactCSSTransitionGroup>
);
}
}
const app = document.getElementById('app');
ReactDOM.render(
<Router history={hashHistory}>
<Route path="/" component={PageOne}></Route>
<Route path="two" component={PageTwo}></Route>
</Router>,
app);
和CSS：
.example-enter {
opacity: 0.01;
}
.example-enter.example-enter-active {
opacity: 1;
transition: opacity 500ms ease-in;
}
.example-leave {
opacity: 1;
}
.example-leave.example-leave-active {
opacity: 0.01;
transition: opacity 300ms ease-in;
}
