javascript - 如何用react-pose实现动画刻度线？

Question

我想重新创建位于 here 的勾号/复选标记的姿势 svg 线动画，但作为带有 react-pose 的 React 组件。我不确定如何实现这一点？网上没有很多使用动画 svg 路径的完整示例，希望堆栈溢出中有人对 react-pose 有足够的了解来帮助我重新创建它。

我尝试创建一个 react 组件，但无法让它工作。 Here is the react component I tried to make.感谢您提供的所有帮助。

这是我想要创建的完整动画

const { tween, physics, easing } = window.popmotion;

const iconProps = {
  loading: {
    opacity: 1,
    pathLength: 45,
    transition: ({ from, to }) => tween({ from, to, ease: easing.easeIn })
  },
  loadingWait: {
    rotate: true, // We're not animating to any specific value, but we want to fire a `transition`
    transition: ({ from }) => physics({ from, velocity: -400 })
  },
  loaded: {
    rotate: false, // Stop any existing animation on this property
    pathLength: 100
  }
};

const tickProps = {
  loaded: { opacity: 1, pathLength: 100 }
};

function init() {
  // Get elements
  const iconDom = document.getElementById('tick-outline-path');
  const tickDom = document.getElementById('tick-path');
  
  // Create posers
  const icon = pose(iconDom, iconProps);
  icon.addChild(tickDom, tickProps);
  
  // Set animation state
  icon.set('loading').then(() => icon.set('loadingWait'));
  setTimeout(() => icon.set('loaded'), 2000);
}

(document.readyState !== 'loading')
  ? init()
  : document.addEventListener('DOMContentLoaded', init);

Answer 1

React Pose 的代码几乎与您发布的普通 Pose 示例完全相同。

唯一的区别是您将制作 path 组件的姿势版本:

const Icon = posed.path(iconProps)
const Tick = posed.path(tickProps)

并在渲染组件时将 loading/loadingWait/loaded 状态作为 pose 属性传递给这两个组件。
