jQuery滚动到下一部分 [英] JQuery Scroll to Next Section

问题描述
有人可以帮忙吗?
我似乎有两个问题:
- 页面无法滚动，并且
- 当触发器滚动单击3次时，.top未定义.
.hero-banner是全屏幻灯片.单击.trigger-scroll时，页面需要滚动到sections.scroll-here.到达最后一个部分时，需要滚动到顶部.
.hero-banner is a full screen slideshow. When .trigger-scroll is clicked, page needs to scroll to sections.scroll-here. When reached last section needs to scroll to top.
预先感谢您的回答.
HTML:
<section class="hero-banner">full screen section</section>
<div class="trigger-scroll"></div>
<section class="scroll-here" id="first-section">some content</section>
<section class="scroll-here" id="second-section">some content</section>
<section class="scroll-here" id="third-section">some content</section>
JS:
$(document).ready(function() {
$('.page-scroller', function() {
var $scrollSection = $('.scroll-here')
var $scrollTrigger = $('.trigger-scroll')
var nextSection = 0;
$scrollTrigger.on( 'click', function() {
$(this).removeClass('go-to-top');
// If at last section, scroll back to top on next click:
if (nextSection >= $scrollSection.length) {
$('html, body').animate({ scrollTop: 0 }, 1000);
nextSection = 0;
return;
}
// If you've already scrolled down and then click button, run a check
// to find next section position so you don't go backwards:
while ( $('body').scrollTop() > $($scrollSection[nextSection]).offset().top ) {
nextSection++;
}
// If next section is the last, add class to rotate arrow graphic:
if (nextSection === ($scrollSection.length - 1)) {
$(this).addClass('go-to-top');
}
// Move to next section and increment counter check:
$( 'html, body' ).animate({ scrollTop: $($scrollSection[nextSection]).offset().top }, 1000);
nextSection++;
});
});
});
推荐答案
几个小时后，试图弄清为什么<scrollTop>无效的原因，我发现<body>标记的css样式为<height:100%;>弄乱了<offset>.亚历克斯感谢您的帮助.对于其他人，这是一个有效的 JSFiddle链接
After a few hours trying to figure out why <scrollTop> wasn't working, I found that <body> tag had a css style of <height:100%;> which was messing up the <offset>. Alex thanks for your help. For others, here is a working JSFiddle Link
