jquery reverse array

I have the following snippet which returns some youtube id's. Now I want to reverse the output (because now it is the last first)

if (options.slideshow) {
var links = [];
var $lis = holder.parents('#yt_holder').find('li');
var $as = $lis.children('a');
for(var count = $lis.length-1, i = count; i >= 0; i--){
    links.push(youtubeid($as[i].href));
    }
 slideshow = '&playlist=' + links + '';
 alert(slideshow);
}

I tried .reverse() but some items seems to be missing then

links.reverse().push(youtubeid($as[i].href));

Any help will be appreciated. Ceasar

Hi you after reversing the links array ,you have to assign it to other array and hence it will work.

var slideshow = [];
slideshow = links.reverse();

You should reverse the list after you've accumulated it:

for ( ... ) {
    ...
}
links = links.reverse();

but it would be better to just put the elements into the array in the right order in the first place.

Try adding the videos in the reverse order, so instead of this

for(var count = $lis.length-1, i = count; i >= 0; i--){
    links.push(youtubeid($as[i].href));
    }

Do this

for(var i = 0, count = $lis.length; i < count; i++){
    links.push(youtubeid($as[i].href));
    }
