import React, { useState } from 'react'; import { CSSTransition } from 'react-transition-group'; const FadeExample = () => { const [inProp, setInProp] = useState(false); return ( <div> <button type="button" onClick={() => setInProp(prev => !prev)}>...
When the in prop is set to true, the child component will first receive the class example-enter, then the example-enter-active will be added in the next tick. CSSTransition forces a reflow between before adding the example-enter-active. This is an important trick because it allows us to ...
在动画完成后,原class改变为done表明组件动画已经应用完成并加载完成。 当组件的in属性变为true时,组件的className将被赋值为example-enter,并在下一刻添加example-enter-active的CSS class名。这些都是基于className属性的约定。即:原组件带有classname="animate-rotate",则enter状态时,变为"animate-rotate-enter"。 看...

This is how React will determine which children have entered, left, ...
startTransitionanduseTransitionlet you mark some state updates as not urgent. Other state updates are considered urgent by default. React will allow urgent state updates (for example, updating a text input) to interrupt non-urgent state updates (for example, rendering a list of search results). ...
