我正在使用 barba.js 淡入新页面。代码必须放置在 barba 包装器 div 之间。但是,当我单击指向新页面的链接时,新页面会在与前一页相同的位置淡入。因此,如果用户单击链接,新页面将在 close 中加载,这是我不希望的。

如何让新页面加载到顶部?

我在堆栈上找到了有关 scrollRestoration 函数的答案,但我仍然不明白如何使其工作。

有人可以帮我编译下面的js代码,添加一些css或html来解决这个问题吗?

$(window).scrollTop(0);
if ('scrollRestoration' in history) {
history.scrollRestoration = 'manual';
}
function delay(n) {
n = n || 2000;
return new Promise((done) => {
setTimeout(() => {
done();
}, n);
});
}

function pageTransition() {
var tl = gsap.timeline();

tl.to(".animate-this", {
duration: .2, opacity: 0, delay: 0, y: 30, //scale:0, delay: 0.2,
});
tl.to(".animate-this", {
duration: 0, opacity: 0, delay: 0, scale:0, //scale:0, delay: 0.2,
});

tl.fromTo(".loading-screen", {width: 0, left: 0}, {
duration: 1,
width: "100%",
left: "0%",
ease: "expo.inOut",
delay: 0.3,
});

tl.to("#svg-1", {
duration: 1, opacity: 0, y: 30, stagger: 0.4, delay: 0.2,
});

tl.to(".loading-screen", {
duration: 1,
width: "100%",
left: "100%",
ease: "expo.inOut",
delay: 0, //CHANGE TIME HERE END TRANS
});




tl.set(".loading-screen", { left: "-100%", });
tl.set("#svg-1", { opacity: 1, y: 0 });
}



function contentAnimation() {
var tl = gsap.timeline();
tl.from(".animate-this", { duration: .5, y: 30, opacity: 0, stagger: 0.4, delay: 0.2 });
}

$(function () {
barba.init({
sync: true,

transitions: [
{
async leave(data) {
const done = this.async();

pageTransition();
await delay(2500);
done();
},

async enter(data) {
contentAnimation();
},

async once(data) {
contentAnimation();
},
},
],
});
});

这里还有一个代码笔来检查我的问题(html,css):<强> https://codepen.io/cat999/project/editor/AEeEdg

最佳答案

scrollRestoration 应该不是必需的,这可以通过在转换期间重置滚动位置来完成:

  tl.fromTo(".loading-screen", {width: 0, left: 0}, {
duration: 1,
width: "100%",
left: "0%",
ease: "expo.inOut",
delay: 0.3,
onComplete: function() {
window.scrollTo(0, 0);
}
});
