My website has a sticky footer with a clickable arrow that allows users to navigate through the sections. However, I am facing an issue where the arrow does not disappear once the last section is reached. Being new to jQuery and JS, I'm unsure how to solve this problem.
I have tried the following code without success:
document.onscroll = function() {
if (window.innerHeight + window.scrollY > document.body.clientHeight) {
document.getElementById('arrow').style.display='none';
}
}
Here is the remaining code:
<div class="scroller animated pulse infinite" id="arrow">
<i class="ion-md-arrow-dropdown"></i>
</div>
CSS:
.scroller {
height: 80px;
position: fixed;
bottom: 0;
left: 0;
width: 100%;
background-color: transparent;
box-shadow: 0 2px 2px #ddd;
z-index: 1;
}
.scroller i {
color: #fff;
-webkit-text-stroke: 1px #555;
font-size: 70px;
margin: 0 48.5%;
}
JS:
$(function(){
var pagePositon = -1,
sectionsSeclector = '.scrolling_section',
$scrollItems = $(sectionsSeclector),
offsetTolorence = 30,
pageMaxPosition = $scrollItems.length - 1;
//Map the sections:
$scrollItems.each(function(index,ele) { $(ele).attr("debog",index).data("pos",index); });
// Bind to scroll
$(window).bind('scroll',upPos);
//Move on click:
$('#arrow i').click(function(e){
if ($(this).hasClass('ion-md-arrow-dropdown') && pagePositon+0 <= pageMaxPosition) {
pagePositon++;
$('html, body').stop().animate({
scrollTop: $scrollItems.eq(pagePositon).offset().top - $('nav').height()
}, 2000);
}
});
//Update position func:
function upPos(){
var fromTop = $(this).scrollTop();
var $cur = null;
$scrollItems.each(function(index,ele){
if ($(ele).offset().top < fromTop + offsetTolorence) $cur = $(ele);
});
if ($cur != null && pagePositon != $cur.data('pos')) {
pagePositon = $cur.data('pos');
}
}
});
