Question

I’d like to create an if – else condition system which allows scrolling up only when the top margin is different than 0. I’ll use the .animate action in jquery to create an animation.

$('#up-arrow a').click(function(){
    if('#slider'.css(margin-top)!='0px')
        $('#slider').animate({'margin-top':'+=320px'});
    else

Can someone please correct this for me? It works without the if, but after I added the if-else it does nothing.

Answer 1

Instead of this

if('#slider'.css(margin-top)!='0px')

Try this

if($('#slider').css("margin-top")!='0px')
