我想更改页面中间的滚动方向。
我尝试使用" jInvertScroll",但此插件在css中增加left
,如下所示:left: /* increase on scroll */ px ;
因此,如果我想将滚动方向更改为页面中间,left
将具有如下值:left: -1500px;
那是我的问题。 还有其他办法吗?
HTML:
<div class="vertical"></div>
<div class="menu-change"></div>
<div class="horizontal">
<p>scroll</p>
</div>
CSS:
body {
overflow-x: hidden;
padding: 0;
margin: 0;
}
.scroll {
position: fixed;
bottom: 0;
left: 0;
}
.vertical {
width: 100vw;
height: 2500px;
background-image: url(https://source.unsplash.com/random);
}
.horizontal {
width: 8500px;
height: 100vh;
background-image: url(https://source.unsplash.com/random);
}
JS:
$(document).ready(function(){
var scroll_start = 0;
var startchange = $('.menu-change');
var offset = startchange.offset();
$(document).scroll(function() {
scroll_start = $(this).scrollTop();
if(scroll_start > offset.top) {
$('.horizontal').addClass('scroll');
var elem = $.jInvertScroll(['.scroll'],
{
onScroll: function(percent) {
console.log(percent);
}
});
$(window).resize(function() {
if ($(window).width() <= 0) {
elem.destroy();
}
else {
elem.reinitialize();
}
});
} else {
$('.horizontal').removeClass('scroll');
}
});
});
