Hide an element with jQuery whilst scrolling

Note: This article has been marked for a quality review and will soon be updated.

Today I came across an interesting problem that no amount of Google searches could solve. So I had to knuckle down and come up with a solution - and surprisingly it was much more simple that it had first appeared.

So the problem is hiding an element when a user is scrolling - it might be a menu, a header, or a picture of my cat, Sophie. Either way we can't just use the simple delay() function in jQuery to help us out - we need to use some raw JavaScript. To accomplish this we will create a variable into which we will place the current scroll amount of the page, we will then wait for a period of time, and check if that scroll amount has changed. If it has we will leave the element hidden, otherwise we'll show it to the user again.

And here's the rather simple code to do just that:

$(document).scroll(function(){
	$('section').fadeOut();
	
	var scrollA = $('body').scrollTop();
	
	setTimeout(function(){
		if(scrollA == $('body').scrollTop()){
			$('section').fadeIn();
		}
	}, 200);
});

And there we have it! A really simple effect made easy with a tiny bit of JavaScript.
