吸顶建议使用相交区域createIntersectionObserver去做； 如果使用onPageScroll，函数截流或者抽取组件，减少setData影响范围

建议分页采用二维数组

设置一定的touchmove触发角度（与x轴的夹角）； touchmove的时候设置一个变量为false，touchmove的时候，如果为false不响应事件，之后设置为true

可以，在整个屏幕上覆盖一个view，绑定catchtouchmove为空函数

我感觉严格的抛物线动画不能通过createAnimation实现，但是可以通过帧动画。 这是我之前写的抛物线组件： ts： Component({ data: { left: 0, top: 0, hidden: true, }, timer: 0, detached() { this.cancel(); }, pageLifetimes: { hide() { this.cancel(); }, }, methods: { animate(options: IOptions & { onEnd: () => void }) { const { onEnd } = options; this.cancel(false); this.setData({ left: options.start.x, top: options.start.y, hidden: false, }); parabolaAnimate(options, ({ x, y }, timer) => { this.setData({ left: x, top: y }); this.timer = timer; if (timer === 0) { this.setData({ hidden: true }); if (typeof onEnd === 'function') { onEnd(); } } }); }, cancel(hidden = true) { if (this.timer) { clearInterval(this.timer); this.timer = 0; } if (hidden) { this.setData({ hidden: true }); } }, }, }); interface IOptions { start: { x: number; y: number }; end: { x: number; y: number }; topY: number; gforce?: number; frameDuration?: number; } function parabolaAnimate( options: IOptions, callback: (ponit: { x: number; y: number }, timer: number) => void ) { const { start, end, topY, gforce = 2000, frameDuration = 10 } = options; const tStartToTop = Math.sqrt((Math.abs(topY - start.y) * 2) / gforce); const tTopToEnd = Math.sqrt((Math.abs(topY - end.y) * 2) / gforce); const tFrame = frameDuration / 1000; let tRest = tStartToTop + tTopToEnd; let vx = (end.x - start.x) / (tStartToTop + tTopToEnd); let vy = -gforce * tStartToTop; let startX = start.x; let startY = start.y; let timer = setInterval(() => { const ponit = { x: startX + vx * tFrame, y: startY + vy * tFrame + (gforce * tFrame * tFrame) / 2, }; vy = vy + gforce * tFrame; tRest = tRest - tFrame; startX = ponit.x; startY = ponit.y; if (tRest <= 0) { clearInterval(timer); timer = 0; } callback(ponit, timer); }, frameDuration); } wxml： <view hidden="{{hidden}}" class="parabola-ball" style="left:{{left}}px;top:{{top}}px;"></view> 调用： Page({ onReady() { this.parabolaBall = this.selectComponent("#parabola-ball"); this.systemInfo = wx.getSystemInfoSync(); }, animateBall(e) { const { screenHeight, screenWidth } = this.systemInfo; const { clientX, clientY } = e.touches[0]; const start = { x: clientX, y: clientY }; this.parabolaBall.animate({ start, end: { x: screenWidth * 0.62, y: screenHeight + 30 }, topY: clientY + 50 }); } }); 备注：重点在于抛物线函数parabolaAnimate的算法，其中起点坐标，终点坐标，顶点y坐标，重力加速度值是决定抛物线轨迹的必须要素。

不可以
