My website features a sticky navigation, but it won't work on mobile devices...
How do I make it sticky on mobile devices, or how do I prevent it from being sticky (while keeping the navigation, of course)?
I looked everywhere for an answer, but couldn't find one that worked (and didn't disable my navigation:) Your help is much appreciated!
This is a part of my index.html header:
<head>
<link href="css/reset.css" rel="stylesheet" type="text/css" />
<link href="css/960.css" rel="stylesheet" type="text/css" />
<link href="css/styles.css" rel="stylesheet" type="text/css" />
<link href="fancybox/jquery.fancybox-1.3.4.css" rel="stylesheet" type="text/css" />
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js" type="text/javascript"></script>
<script src="js/smooth-scroll.js" type="text/javascript"></script>
<script src="js/jquery.sticky.js" type="text/javascript"></script>
<script src="contactform.js" type="text/javascript"></script>
<!-- sticky nav -->
<script type="text/javascript">
$(window).load(function(){
$("nav").sticky({ topSpacing: 0, className: 'sticky', center: true });
});
</script>
</head>
And this is the code in the jquery.sticky javascript:
(function($) {
var defaults = {
topSpacing: 0,
bottomSpacing: 0,
className: 'is-sticky',
center: false
},
$window = $(window),
$document = $(document),
sticked = [],
windowHeight = $window.height(),
scroller = function() {
var scrollTop = $window.scrollTop(),
documentHeight = $document.height(),
dwh = documentHeight - windowHeight,
extra = (scrollTop > dwh) ? dwh - scrollTop : 0;
for (var i = 0; i < sticked.length; i++) {
var s = sticked[i],
elementTop = s.stickyWrapper.offset().top,
etse = elementTop - s.topSpacing - extra;
if (scrollTop <= etse) {
if (s.currentTop !== null) {
s.stickyElement.css('position', '').css('top', '').removeClass(s.className);
s.currentTop = null;
}
}
else {
var newTop = documentHeight - s.elementHeight - s.topSpacing - s.bottomSpacing - scrollTop - extra;
if (newTop < 0) {
newTop = newTop + s.topSpacing;
} else {
newTop = s.topSpacing;
}
if (s.currentTop != newTop) {
s.stickyElement.css('position', 'fixed').css('top', newTop).addClass(s.className);
s.currentTop = newTop;
}
}
}
},
resizer = function() {
windowHeight = $window.height();
};
// should be more efficient than using $window.scroll(scroller) and $window.resize(resizer):
if (window.addEventListener) {
window.addEventListener('scroll', scroller, false);
window.addEventListener('resize', resizer, false);
} else if (window.attachEvent) {
window.attachEvent('onscroll', scroller);
window.attachEvent('onresize', resizer);
}
$.fn.sticky = function(options) {
var o = $.extend(defaults, options);
return this.each(function() {
var stickyElement = $(this);
if (o.center)
var centerElement = "margin-left:auto;margin-right:auto;";
stickyId = stickyElement.attr('id');
stickyElement
.wrapAll('<div id="' + stickyId + 'StickyWrapper" style="' + centerElement + '"></div>')
.css('width', stickyElement.width());
var elementHeight = stickyElement.outerHeight(),
stickyWrapper = stickyElement.parent();
stickyWrapper
.css('width', stickyElement.outerWidth())
.css('height', elementHeight)
.css('clear', stickyElement.css('clear'));
sticked.push({
topSpacing: o.topSpacing,
bottomSpacing: o.bottomSpacing,
stickyElement: stickyElement,
currentTop: null,
stickyWrapper: stickyWrapper,
elementHeight: elementHeight,
className: o.className
});
});
};
})(jQuery);
