gsap.to(target, { x: 100, duration: 1 }); // 动画到目标值
gsap.from(target, { opacity: 0 }); // 从起始值动画
gsap.fromTo(target, { x: 0 }, { x: 100 }); // 明确的从...到...
gsap.set(target, { x: 0, opacity: 1 }); // 即时设置(无动画)
优先使用变换属性(x, y, scale, rotation)而非布局属性(top, left, width, height)。
const tl = gsap.timeline({ defaults: { ease: "power3.out", duration: 0.6 } });
tl.from(".hero-title", { y: 30, autoAlpha: 0 })
.from(".hero-subtitle", { y: 20, autoAlpha: 0 }, "<0.1")
.from(".hero-cta", { scale: 0.9, autoAlpha: 0 }, "<0.15");
规则:
defaults 确保一致性,有意识地覆盖tl.to(a, {...}) // 追加到末尾
tl.to(b, {...}, "<") // 与上一个同时开始
tl.to(c, {...}, ">") // 在上一个结束后开始
tl.to(d, {...}, "+=0.3") // 上一个结束后等待 0.3 秒
tl.to(e, {...}, "label") // 在标签处开始
snap 工具gsap.utils.mapRange(), clamp(), snap(), toArray()// ❌ 错误:每次事件都创建新补间
window.addEventListener("pointermove", (e) => {
gsap.to(".cursor", { x: e.clientX, y: e.clientY });
});
// ✅ 正确:重用 quickTo 实例
const xTo = gsap.quickTo(".cursor", "x", { duration: 0.2, ease: "power3" });
const yTo = gsap.quickTo(".cursor", "y", { duration: 0.2, ease: "power3" });
window.addEventListener("pointermove", (e) => { xTo(e.clientX); yTo(e.clientY); });
// ✅ 正确:超快速直接更新(无补间)
const setX = gsap.quickSetter(".cursor", "x", "px");
const setY = gsap.quickSetter(".cursor", "y", "px");
window.addEventListener("pointermove", (e) => { setX(e.clientX); setY(e.clientY); });
// ❌ 错误:混合读取和写入
elements.forEach(el => {
const rect = el.getBoundingClientRect(); // 读取
gsap.set(el, { x: rect.width }); // 写入
});
// ✅ 正确:批量读取,然后写入
const rects = elements.map(el => el.getBoundingClientRect()); // 全部读取
elements.forEach((el, i) => gsap.set(el, { x: rects[i].width })); // 全部写入
invalidateOnRefreshScrollTrigger.batch()ScrollTrigger 支持基于滚动的触发、擦除、固定、捕捉等。
// 模式 A:内联 scrollTrigger
gsap.to(".box", {
x: 500,
scrollTrigger: {
trigger: ".box",
start: "top 80%",
end: "top 30%",
scrub: 1,
markers: true // 仅开发环境
}
});
// 模式 B:时间线 + ScrollTrigger.create
const tl = gsap.timeline();
tl.from(".item", { y: 50, autoAlpha: 0, stagger: 0.1 });
ScrollTrigger.create({
animation: tl,
trigger: ".section",
start: "top 70%",
toggleActions: "play none none reverse"
});
const tl = gsap.timeline();
tl.from(".panel1", { autoAlpha: 0, y: 20 })
.to(".panel1", { autoAlpha: 0 })
.from(".panel2", { autoAlpha: 0, y: 20 }, "<");
ScrollTrigger.create({
animation: tl,
trigger: ".story",
start: "top top",
end: "+=2000",
scrub: 1,
pin: true,
invalidateOnRefresh: true
});
ScrollTrigger.batch(".card", {
onEnter: (elements) => gsap.from(elements, { y: 30, autoAlpha: 0, stagger: 0.1 }),
start: "top 85%"
});
const sections = gsap.utils.toArray(".panel");
gsap.to(sections, {
xPercent: -100 * (sections.length - 1),
ease: "none",
scrollTrigger: {
trigger: ".horizontal-container",
pin: true,
scrub: 1,
end: () => "+=" + document.querySelector(".horizontal-container").offsetWidth
}
});
gsap.matchMedia().add({
"(prefers-reduced-motion: no-preference) and (min-width: 768px)": () => {
// 桌面端动画
gsap.from(".hero", {
y: 50, autoAlpha: 0,
scrollTrigger: { trigger: ".hero", start: "top 80%" }
});
},
"(prefers-reduced-motion: reduce)": () => {
// 减少运动:即时可见,无动画
gsap.set(".hero", { autoAlpha: 1 });
}
});
使用 ScrollTo 实现到锚点/区块的平滑导航。
gsap.registerPlugin(ScrollToPlugin);
// 滚动到元素
gsap.to(window, { duration: 1, scrollTo: "#pricing", ease: "power2.out" });
// 滚动到位置
gsap.to(window, { duration: 1, scrollTo: { y: 500, autoKill: true } });
// 带偏移量
gsap.to(window, { scrollTo: { y: "#section", offsetY: 80 } });
ScrollSmoother 创建基于原生滚动的平滑和视差效果。
gsap.registerPlugin(ScrollTrigger, ScrollSmoother);
// 必需的 HTML 结构:
// <div id="smooth-wrapper">
// <div id="smooth-content">...内容...</div>
// </div>
const smoother = ScrollSmoother.create({
wrapper: "#smooth-wrapper",
content: "#smooth-content",
smooth: 1.5, // 平滑秒数
effects: true // 启用 data-speed/data-lag 属性
});
// HTML: <div data-speed="0.5">慢速视差</div>
// <div data-speed="2">快速视差</div>
// <div data-lag="0.5">拖尾效果</div>
注意事项:
refresh()normalizeScroll: true 确保移动端一致性使用 Observer 将滚轮/触摸/指针事件统一为一致的“意图”信号。
gsap.registerPlugin(Observer);
Observer.create({
target: window,
type: "wheel,touch,pointer",
onUp: () => goToPrevSection(),
onDown: () => goToNextSection(),
tolerance: 50,
preventDefault: true
});
用例:
当元素改变布局时使用 Flip(网格重新排序,模态框展开,共享元素过渡)。
gsap.registerPlugin(Flip);
// 1. 捕获状态
const state = Flip.getState(".cards");
// 2. 改变布局(DOM/CSS)
container.classList.toggle("grid");
// 3. 从旧状态动画
Flip.from(state, {
duration: 0.6,
ease: "power2.inOut",
stagger: 0.05,
absolute: true,
onEnter: elements => gsap.fromTo(elements, { autoAlpha: 0 }, { autoAlpha: 1 }),
onLeave: elements => gsap.to(elements, { autoAlpha: 0 })
});
gsap.registerPlugin(Draggable, InertiaPlugin);
Draggable.create(".slider", {
type: "x",
bounds: ".container",
inertia: true, // 需要 InertiaPlugin
snap: value => Math.round(value / 200) * 200, // 捕捉到 200px 间隔
onDrag: function() { console.log(this.x); },
onThrowComplete: () => console.log("投掷完成")
});
DIY 动量(如果 InertiaPlugin 不可用):
let velocity = 0;
let lastX = 0;
Draggable.create(".element", {
type: "x",
onDrag: function() {
velocity = this.x - lastX;
lastX = this.x;
},
onDragEnd: function() {
// 使用指数衰减的 DIY 动量
gsap.to(this.target, {
x: `+=${velocity * 10}`,
duration: Math.abs(velocity) * 0.1,
ease: "power2.out"
});
}
});
gsap.registerPlugin(SplitText);
const split = new SplitText(".headline", { type: "chars,words,lines" });
gsap.from(split.chars, {
y: 20,
autoAlpha: 0,
stagger: 0.02,
duration: 0.4,
ease: "power3.out"
});
// 清理(对响应式很重要)
// split.revert();
DIY 替代方案(如果需要):
function splitIntoSpans(el) {
const text = el.textContent;
el.innerHTML = text.split('').map(char =>
char === ' ' ? ' ' : `<span class="char">${char}</span>`
).join('');
return el.querySelectorAll('.char');
}
gsap.registerPlugin(ScrambleTextPlugin);
gsap.to(".title", {
duration: 1.5,
scrambleText: {
text: "DECODED MESSAGE",
chars: "XO",
revealDelay: 0.5
}
});
gsap.registerPlugin(TextPlugin);
gsap.to(".counter", {
duration: 2,
text: { value: "100%", delimiter: "" },
ease: "none"
});
gsap.registerPlugin(DrawSVGPlugin);
gsap.from(".line-path", {
drawSVG: 0, // 或 "0%" / "50% 50%"
duration: 2,
ease: "power2.inOut"
});
gsap.registerPlugin(MorphSVGPlugin);
gsap.to("#shape1", {
morphSVG: "#shape2",
duration: 1,
ease: "power2.inOut"
});
gsap.registerPlugin(MotionPathPlugin);
gsap.to(".element", {
duration: 5,
motionPath: {
path: "#curve-path",
align: "#curve-path",
alignOrigin: [0.5, 0.5],
autoRotate: true
},
ease: "none"
});
gsap.registerPlugin(Physics2DPlugin, PhysicsPropsPlugin);
// 2D 物理(速度,角度,加速度,重力)
gsap.to(".ball", {
duration: 3,
physics2D: {
velocity: 500,
angle: -60,
gravity: 500
}
});
// 任何属性的物理效果
gsap.to(".element", {
duration: 2,
physicsProps: {
x: { velocity: 100, acceleration: 50 },
rotation: { velocity: 360 }
}
});
gsap.registerPlugin(CustomEase, CustomWiggle, CustomBounce);
// 自定义 SVG 路径缓动
CustomEase.create("myEase", "M0,0 C0.25,0.1 0.25,1 1,1");
gsap.to(".el", { x: 100, ease: "myEase" });
// 摆动缓动
CustomWiggle.create("myWiggle", { wiggles: 6, type: "easeOut" });
gsap.to(".el", { rotation: 20, ease: "myWiggle" });
// 自定义弹跳
CustomBounce.create("myBounce", { strength: 0.7, squash: 2 });
gsap.to(".el", { y: 300, ease: "myBounce" });
gsap.registerPlugin(GSDevTools);
// 附加到特定时间线
const tl = gsap.timeline();
tl.to(".box", { x: 500 })
.to(".box", { rotation: 360 });
GSDevTools.create({ animation: tl });
// 或附加到全局时间线
GSDevTools.create();

Prefer transform properties (x, y, scale, rotation) over layout props (top, left, width, height).
const tl = gsap.timeline({ defaults: { ease: "power3.out", duration: 0.6 } });

Rules:
defaults for consistency, override intentionallytl.to(a, {...}) // appends at end
tl.to(b, {...}, "<") // starts same time as previous
tl.to(c, {...}, ">") // starts after previous ends
tl.to(d, {...}, "+=0.3") // wait 0.3s after last end
tl.to(e, {...}, "label") // starts at label
snap utility for grid alignmentgsap.utils.mapRange(), clamp(), snap(), toArray()// ❌ BAD: Creates new tween every event
window.addEventListener("pointermove", (e) => {

});
// ✅ GOOD: Reuses quickTo instances
const xTo = gsap.quickTo(".cursor", "x", { duration: 0.2, ease: "power3" });
const yTo = gsap.quickTo(".cursor", "y", { duration: 0.2, ease: "power3" });
window.addEventListener("pointermove", (e) => { xTo(e.clientX); yTo(e.clientY); });
// ✅ GOOD: Ultra-fast direct updates (no tween)
const setX = gsap.quickSetter(".cursor", "x", "px");
const setY = gsap.quickSetter(".cursor", "y", "px");
window.addEventListener("pointermove", (e) => { setX(e.clientX); setY(e.clientY); });
// ❌ BAD: Mixed reads and writes
elements.forEach(el => {
const rect = el.getBoundingClientRect(); // read
gsap.set(el, { x: rect.width }); // write
});
// ✅ GOOD: Batch reads, then writes
const rects = elements.map(el => el.getBoundingClientRect()); // all reads
elements.forEach((el, i) => gsap.set(el, { x: rects[i].width })); // all writes
invalidateOnRefresh when layout-driven values are usedScrollTrigger.batch() for lists of similar elementsScrollTrigger enables scroll-based triggering, scrubbing, pinning, snapping, etc.

Use cases:
Use Flip when elements change layout (grid reorder, modal expansion, shared-element transitions).
gsap.registerPlugin(Flip);
// 1. Capture state
const state = Flip.getState(".cards");
// 2. Change layout (DOM/CSS)
container.classList.toggle("grid");
// 3. Animate from old state
Flip.from(state, {
duration: 0.6,
ease: "power2.inOut",
stagger: 0.05,
absolute: true,
onEnter: elements => gsap.fromTo(elements, { autoAlpha: 0 }, { autoAlpha: 1 }),
onLeave: elements => gsap.to(elements, { autoAlpha: 0 })
});
gsap.registerPlugin(Draggable, InertiaPlugin);
Draggable.create(".slider", {

onDrag: function() { console.log(this.x); },
onThrowComplete: () => console.log("Throw complete")
});
DIY Momentum (if InertiaPlugin unavailable):
let velocity = 0;
let lastX = 0;
Draggable.create(".element", {
type: "x",
onDrag: function() {
velocity = this.x - lastX;
lastX = this.x;
},
onDragEnd: function() {
// DIY momentum with exponential decay
gsap.to(this.target, {
x: `+=${velocity * 10}`,

el.innerHTML = text.split('').map(char =>
char === ' ' ? ' ' : `<span class="char">${char}</span>`
