如何让React Transition Group的生命周期发挥作用?
我有一个包含2个组件的简单示例。 Projects one,它将使用ReactTransitionGroup和Index Componente,这是我想从ReactTransitionGroup接收生命周期的那个:
import React from 'react';
import Index from 'components/views/components/Index';
import TransitionGroup from 'react-addons-transition-group'
class Projects extends React.Component {
render () {
return (
<div className='content'>
<TransitionGroup>
<Index />
</TransitionGroup>
</div>
);
}
}
我的索引组件:
class Index extends React.Component {
componentWillAppear (callback) {
console.log('will appear');
callback();
}
componentDidAppear () {
console.log('did appear');
}
componentWillEnter (callback) {
console.log('will enter');
callback();
}
componentDidEnter () {
console.log('did enter');
}
componentWillLeave (callback) {
console.log('will leave');
callback();
}
componentDidLeave () {
console.log('did leave');
}
render () {
return (
<div className='index'>
<h2>Index Page</h2>
</div>
);
}
}
我只需要生命周期调度。
我发现一篇关于我的问题的精彩文章,但我无法复制结果: https://medium.com/@slapspapayas/reacttransitiongroup-explained-through-failure-629efe364866
反应版本:^ 16.2.0
React Addons Transition Group :^ 15.6.2
谢谢!

实际上,这些生命周期已删除。参见migration 从迁移开始,将删除子生命周期。我们可以将回调传递给Transition组件:
<Transition
{...props}
onEnter={handleEnter}
onEntering={handleEntering}
onEntered={handleEntered}
onExit={handleExit}
onExiting={handleExiting}
onExited={handleExited}
/>
