I have an trackarray where i want to be able remove all but first element.

If i stand on last element i pop it otherwise i slice it. But if i pop all tracks, i never able to pop track 2. Similar when splice invoked it will not splice when standing on track one, and stop remove tracks when it removed all beyond track 2. "Because then pop is invoked", i probably should used length instead of maxtrack.

function removeTrack(tracknr){
console.log(maxtrack+" AND "+tracknr);
if (maxtrack>1){ 
if (maxtrack==tracknr){ track.pop(); tracknr--; maxtrack--;document.getElementById("track").value--;}
else {track.splice(tracknr, 1); maxtrack--;}
changeTrack();}
}
