Ola 介绍
Ola 是一个简单的 JavaScript
库，实时插入/插入（inbetweening /
interpolating
）数字的平滑动画库。
// Start tracking the value
const pos = Ola({ y: 0 });
// Set the value to update async
pos.set({ y: 100 });
// Read the evolution over time
setInterval(() => graph(pos.y), 5);
支持多值和多维度
const pos = Ola({ x: 0, y: 0 });
window.addEventListener('click', e => {
pos.set({ x: e.pageX, y: e.pageY });
});
setInterval(() => {
ball.style.left = `${pos.x}px`;
ball.style.top = `${pos.y}px`;
}, 10);
支持很多独立的实例
// Generates 1000 instances seamlessly
const dots = Ola(Array(1000).fill(0));
// Everything updates every 600ms
setInterval(() => dots.forEach((dot, i) => {
dots[i] = Math.random();
}), 600);
// ... read + paint screen here
