var $ pages = $(。page),tot = $ pages.length,c = 0,pagePos = 0,down = 0,listen = true; $('html,body')。on('DOMMouseScroll mousewheel',function(e){e.preventDefault(); if(!listen)return; listen = false; down = e.originalEvent .detail> 0 || e.originalEvent.wheelDelta <0; c = Math.min(Math.max(0,down?++ c:-c),tot-1); pagePos = $ pages.eq (c).offset()。top; $(this).stop()。animate({scrollTop:pagePos},650,function(){listen = true;});});
* {margin:0;}。page {min-height:100vh;} code> < script src =https://ajax.googleapis。 com / ajax / libs / jquery / 2.1.1 / jquery.min.js>< / script>< div class =pagestyle =background:#0bf> PAGE 1< / div> ; div class =pagestyle =background:#fb0> PAGE 2< / div>< div class =pagestyle =background:#0fb> PAGE 3< / div>< div class =pagestyle =background:#b0f>第4页< / div>
PS:
使用 .position()。top;
$ c> .page 在可滚动DIV内,如 $(#pagesParent)
(而不是 $ 'html,body')
)
注意: br>
移动,您可能需要调整浏览器标签栏高度的值(或者最好,完全防止这种行为)。你有这个想法
can anybody help me understand how Honda achieved this effect: http://testdays.hondamoto.ch/
I mean the ease when you scroll.
解决方案
var $pages = $(".page"),
tot = $pages.length,
c = 0, pagePos = 0, down = 0, listen = true;
$('html, body').on('DOMMouseScroll mousewheel', function(e) {
e.preventDefault();
if(!listen)return;
listen = false;
down = e.originalEvent.detail > 0 || e.originalEvent.wheelDelta < 0;
c = Math.min(Math.max(0, down ? ++c : --c), tot-1);
pagePos = $pages.eq(c).offset().top;
$(this).stop().animate({scrollTop: pagePos}, 650, function(){
listen = true;
});
});
*{margin:0;}
.page{min-height:100vh;}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="page" style="background:#0bf">PAGE 1</div>
<div class="page" style="background:#fb0">PAGE 2</div>
<div class="page" style="background:#0fb">PAGE 3</div>
<div class="page" style="background:#b0f">PAGE 4</div>
P.S:
Use .position().top;
if your .page
s are inside a scrollable DIV like $("#pagesParent")
(instead of $('html, body')
)
Notice:
for mobile you might want to adjust the value accounting for the browser's tabs bar height (or best, prevent that behaviour at all). You got the idea
