Java Script Variation For Website

Question

The website here has a music player http://www.numberonedesigns.com/ubermusic.com/ ... When hitting the next button with random highlighted it wont randomize correctly. It always goes back to the first song on the play-list then randomizes on the next.. Here's the variable code. I tried messing with it for a while but decided I needed some help

$next.click(function(){
 var num = 0;
 $.cookie('plate_time', 1);
 if($random.hasClass('active')){
 while(num == $audio.currentTrack){num = Math.floor(Math.random() * (opt.playlist.length));}
 }else{
 num = $audio.currentTrack - 1;
 }
 $audio.loadTrack(num);
 });
 $playlist.on('click', '.track', function(){
 $audio.loadTrack($(this).attr('rel'));
 });
 $prev.click(function(){
 var num = 0;
 $.cookie('plate_time', 0);
 if($random.hasClass('active')){
 while(num == $audio.currentTrack){num = Math.floor(Math.random() * (opt.playlist.length));}
 }else{
 num = $audio.currentTrack - 1;
 }
 $audio.loadTrack(num);
 });

Answer 1

Since you asked so nicely:

$next.click(function(){
 var num = Math.floor(Math.random() * (opt.playlist.length)); 
 //Set the random number here.
 $.cookie('plate_time', 1);
 if($random.hasClass('active')){
 while(num == $audio.currentTrack){num = Math.floor(Math.random() * (opt.playlist.length));} 
 // leaving it here JIC you get the same track.
 }else{
 num = $audio.currentTrack - 1; 
 // cos the ordering still works here if not on random. 
 }
 $audio.loadTrack(num);
});
$playlist.on('click', '.track', function(){
 $audio.loadTrack($(this).attr('rel'));
});
$prev.click(function(){
 var num = Math.floor(Math.random() * (opt.playlist.length));
 $.cookie('plate_time', 0);
 if($random.hasClass('active')){
 while(num == $audio.currentTrack){num = Math.floor(Math.random() * (opt.playlist.length));}
 }else{
 num = $audio.currentTrack - 1;
 }
 $audio.loadTrack(num);
});

• No.1Deisgns: That did the trick! I guess it's time to really start learning some JS and not relying on everyone else's plugins. You the man! Thanks Tech Chaos

Answer 2

You're setting num to 0 at the start of the function. This means that when the current track is playlist[0] the function is triggered, but when the current track isn't playlist[0] but num gets set to 0, the random isn't called and playlist[0] is played again. The while check is failing you with the num set to 0 at the start.

• No.1Deisgns: That's what I thought. This is a purchased plugin... What do I do with the 0? Or that line of string? I tried removing it, defining 0 as unlimited and a whole slue of other things. I'm stumped lol
