如何使用 Framer Motion 为数字制作动画?
How to animate number with Framer Motion?
我正在将一个应用程序从 react-spring 迁移到 framer-motion。使用 Spring,我可以为数字设置动画:
export default function MyNumber({ number }) {
const spring: any = useSpring({ from: { number: 0 }, to: { number } });
return (
<animated.div>
{spring.number.interpolate((c) => c.toFixed(1))}
</animated.div>
);
}
我不知道如何使用 Framer-Motion。
所以我找到了答案:
import { animate } from "framer-motion";
import React, { useEffect, useRef } from "react";
function Counter({ from, to }) {
const ref = useRef();
useEffect(() => {
const controls = animate(from, to, {
duration: 1,
onUpdate(value) {
ref.current.textContent = value.toFixed(1);
}
});
return () => controls.stop();
}, [from, to]);
return <p ref={ref} />;
}
export default function App() {
return <Counter from={0} to={65.4} />;
}
