如何将缓动纳入滚动绑定功能？

标签： javascript html css animation scroll

我正在尝试进行垂直滚动。在此HTML上：

<div class="flex-container">
<div class="flex-caption">  
    <div>
        <p>.........</p>
        <h1>..........</h1>
    </div>
</div>
<div class="flex-caption">  
    <div>
        <p>.....</p>
    <h1>...........</h1>
    </div>
</div>
<div class="flex-caption">  
    <div>
        <p>.............</p>
        <h1>........../h1>
    </div>
</div>
</div>

所以我把CSS像这样：

.caption-2 {
overflow: hidden;
position: fixed;
}


.flex-caption {
float: left;
}

.flex-container {
display: inline-flex;
width: 300vw;
transition-timing-function: cubic-bezier(.84,.01,.25,1.01);
transform: translateX(0vw);
}

然后我用他的代码更改transform: translateX(0vw);：

var captionCont, captionItem;

captionCont = document.querySelector(".flex-container");

window.onscroll = function() {scrollPost()};

function scrollPost () {

var y = window.scrollY;
var x = y / 20;
var i = x * 2;
animator(i);

}

function animator (y){
var captionCont;
captionCont = document.querySelector(".flex-container");
captionCont.style.transform = `translateX(${-y}vw)`
}

但是，我想尝试使这些元素滚动而不是滚动，所以它看起来更像是一种动画，而不仅仅是滚动。但是，我不希望触发动画，而是希望从1％到100％的动画受滚动约束。

我该怎么做？三次贝塞尔曲线似乎没什么作用。

我不明白您真正想要的是什么，因为您尚未添加过渡，因此片段中的立方贝塞尔曲线不起作用

var captionCont, captionItem;

captionCont = document.querySelector(".flex-container");

window.onscroll = function() {scrollPost()};
	
function scrollPost () {
	
	var y = window.scrollY;
	var x = y / 20;
	var i = x * 2;
	animator(i);
	
	}

function animator (y){
	var captionCont;
	captionCont = document.querySelector(".flex-container");
	captionCont.style.transform = `translateX(${-y}vw)`
}

包含jQuery.UI脚本，那么您的代码应类似于：

$('a').click(function(){
    var Top = 
$('body').find($(this).attr('href')).offset().top;
    $('html, body').animate({
        scrollTop: Top
    },300, 'easeOutExpo');

    return false;
});
