- Forum: Using jQuery
Greetings :)I have seen posts here and there of people talking about significant differences between slightly different ways of doing the same thing. I have a div with (e.g.) 20 children, but of which 15 are hidden from the overflow.What I already do successfully (amen jquery simplicity) is the following:- function spin() {
- window.setInterval(function() {
- // take last child of #container and prepend it to the same with a slideDown effect so that all other elements shift down all nice and smooth
- $('#container > :last-child').hide().prependTo('#container').slideDown('slow');
- }
- }, 2500); // repeat forever polling at 2.5s
So my question is simple: is there a more efficient way of doing this? I can see I am using twice a selector which contains "#container". I only know the basics of jQuery (which already does/helps a lot hehe) but my instinct tells me using twice the same selector is waste of cpu cycles.
Cheers and pre-thanks!- «Prev
