React Spring是一款基于React的动画库,是在react-motion的基础上进行修改和优化的。它使用Spring动画模型,可以快速创建各种复杂的动画效果,在React应用程序中使用非常便捷。
通过npm进行安装:
npm install react-spring --save
在组件中引入即可使用:
import {useSpring, animated} from 'react-spring'
function Demo() {
const props = useSpring({opacity: 1, from: {opacity: 0}})
return <animated.div style={props}>I will fade in</animated.div>
}
代码片段:
import {useSpring, animated} from 'react-spring'
function Demo() {
const props = useSpring({opacity: 1, from: {opacity: 0}})
return <animated.div style={props}>I will fade in</animated.div>
}
使用useState和useSpring创建可动画的变量:
import React, { useState } from 'react';
import { useSpring, animated } from 'react-spring';
function Demo() {
const [isToggled, setToggle] = useState(false);
const { color } = useSpring({color: isToggled ? 'green' : 'red'});
return (
<>
<animated.h1 style={{ color }}> Hello, React Spring! </animated.h1>
<button onClick={() => setToggle(!isToggled)}>Toggle</button>
</>
);
}
代码片段:
import React, { useState } from 'react';
import { useSpring, animated } from 'react-spring';
function Demo() {
const [isToggled, setToggle] = useState(false);
const { color } = useSpring({color: isToggled ? 'green' : 'red'});
return (
<>
<animated.h1 style={{ color }}> Hello, React Spring! </animated.h1>
<button onClick={() => setToggle(!isToggled)}>Toggle</button>
</>
);
}
以上为React Spring的简单介绍与安装,希望本文档对你有所帮助。
