我正在 ReactJS 和 GatsbyJS (V2)项目中使用 react-transition-group 。
我的页面过渡与动画一起使用,但是当Link
退出时,exiting
动画会被剪切掉,因为可以进入下一页了。
我尝试延迟Link
动作,但是在页面更改被延迟的同时,exit
动画直到delay
结束并且Link
被执行后才被触发
如何delay
进行页面更改,同时启动exiting
动画onClick
?或者,是否有更好的方法或使用props
?
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;
gatsby-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, opacity ${timeout}ms ease`,
transform: `scale(0.98) translateZ(0)`,
opacity: 0
}
};
};
const getTransitionStyle = ({ timeout, status }) =>
getTransitionStyles(timeout)[status];
export default getTransitionStyle;
答案 0 :(得分:4)
Gatsby v2使用的是Reach Router而不是React Router,因此将getUserConfirmation
与replaceHistory
一起使用将不再起作用。在Gatsby v2 RC中,您可以使用react-pose
来创建页面转换,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
在您的页面内:
// Use `posed.div` elements anywhere on the pages.
const Transition = posed.div({
enter: {
opacity: 1,
},
exit: {
opacity: 0,
},
})
// ...
<Transition>Hello World!</Transition>
