Ser*_*lov 2 javascript css jquery scrollbar sticky
我现在正在苦苦寻找一个应该在页面上按比例滚动的粘性元素.尽管页面的高度,从顶部到页脚.所以它实际上在开始时粘在滚动条的顶部,然后在结尾处粘到底部.或者只是跟随滚轮.
有没有机会用jQuery做到这一点?
下面是通常的"粘性"div的起始代码.
$(window).scroll(function(){
$("#sticky")
.animate({"marginTop":($(window).scrollTop())+"px"}, "fast");});

你的意思是这样的吗?
$(window).scroll(function() {
// calculate the percentage the user has scrolled down the page
var scrollPercent = 100 * $(window).scrollTop() / ($(document).height() - $(window).height());
// get the height of the sticky element
var stickyHeight = $('.sticky').height();
// calculate the margin top of the sticky element
var marginTop = (($(window).height() - stickyHeight) / 100) * scrollPercent;
// set margin top of sticky element
$('.sticky').css('marginTop', marginTop);
});
