我在ReactJS和GatsbyJS(V2)项目中使用react-transition-group.
我的页面过渡使用动画但是当链接退出时,退出的动画被缩短,因为下一页已准备好进入.
我已经尝试延迟链接操作,但在页面更改被延迟时,退出动画不会被触发,直到延迟结束并且链接被操作.
如何在启动现有动画onClick的同时延迟页面更改?或者,是否有更好的方式或道具?
这是我的代码
Layout.js
class Layout extends React.Component { ... return ( <Transition>{children}</Transition> ); }
Transition.js
class Transition extends React.Component { constructor(props) { super(props); this.state = { exiting: false }; this.listenerHandler = this.listenerHandler.bind(this); } listenerHandler() { this.setState({ exiting: true }); } componentDidMount() { window.addEventListener(historyExitingEventType,this.listenerHandler); } componentWillUnmount() { window.removeEventListener(historyExitingEventType,this.listenerHandler); } static getDerivedStateFromProps({ exiting }) { if (exiting) { return { exiting: false }; } return null; } render() { const transitionProps = { timeout: { enter: 0,exit: timeout },appear: true,in: !this.state.exiting }; return ( <ReactTransition {...transitionProps}> {status => ( <div style={{ ...getTransitionStyle({ status,timeout }) }} > {this.props.children} </div> )} </ReactTransition> ); } } export default Transition;
盖茨比-config.js
import createHistory from 'history/createBrowserHistory'; const timeout = 1500; const historyExitingEventType = `history::exiting`; const getUserConfirmation = (pathname,callback) => { const event = new CustomEvent(historyExitingEventType,{ detail: { pathname } }); window.dispatchEvent(event); setTimeout(() => { callback(true); },timeout); }; let history; if (typeof document !== 'undefined') { history = createHistory({ getUserConfirmation }); history.block(location => location.pathname); } export const replaceHistory = () => history; export { historyExitingEventType,timeout };
getTransitionStyle.js
const getTransitionStyles = timeout => { return { entering: { transform: `scale(1.05) translateZ(0)`,opacity: 0 },entered: { transition: `transform 750ms ease,opacity ${timeout}ms ease`,transitionDelay: `750ms`,transform: `scale(1) translateZ(0)`,opacity: 1 },exiting: { transition: `transform 750ms ease,transform: `scale(0.98) translateZ(0)`,opacity: 0 } }; }; const getTransitionStyle = ({ timeout,status }) => getTransitionStyles(timeout)[status]; export default getTransitionStyle;
解决方法
Gatsby v2正在使用Reach Router而不是React Router,因此使用带有replaceHistory的getUserConfirmation将不再起作用.在Gatsby v2 RC中,您可以使用react-pose创建页面转换更简单一些:
gatsby-browser.js和gatsby-ssr.js:
import React from "react" import Transition from "./src/components/transition" export const wrapPageElement = ({ element,props }) => { return <Transition {...props}>{element}</Transition> }
transition.js组件:
import React from "react" import posed,{ PoseGroup } from "react-pose" const timeout = 250 class Transition extends React.PureComponent { render() { const { children,location } = this.props const RoutesContainer = posed.div({ enter: { delay: timeout,delayChildren: timeout },}) // To enable page transitions on mount / initial load,// use the prop `animateOnMount={true}` on `PoseGroup`. return ( <PoseGroup> <RoutesContainer key={location.pathname}>{children}</RoutesContainer> </PoseGroup> ) } } export default Transition
在您的网页内:
// Use `posed.div` elements anywhere on the pages. const Transition = posed.div({ enter: { opacity: 1,},exit: { opacity: 0,}) // ... <Transition>Hello World!</Transition>
检查official example是否有工作演示.
