How can we implement a Snapchat-inspired feature in a web application using AngularJS? The idea is to have a div appear when the user scrolls down or pulls the screen down, and then have it pushed back up when they scroll back up.
This functionality is similar to Snapchat's swipe to refresh feature, but with the added twist of keeping the div visible until the user manually scrolls back up.
Appreciate your insights on this matter. Thank you.
Here is a simple code snippet to help you kickstart your project:
inout='in', win = $(window);
win.scroll(function(){
$('#msg').html( win.scrollTop() );
if ( win.scrollTop() > 200 && inout=='in'){
$('#slideOut').animate({
left : 0
},500);
inout = 'out';
}
if (win.scrollTop() < 200 && inout=='out'){
$('#slideOut').animate({
left : '-100%'
},500);
inout = 'in';
}
}); //END win.scroll#wrap{height:2000px;}
#slideOut{position:fixed;top:80px;left:-100%;padding:50px;background:wheat;}
#msg{position:fixed;top:50px;right:10px;padding:20px;background:palegreen;border:1px solid green;text-align:center;}<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div id="slideOut">This div slides out</div>
<div id="wrap">
