#36088 — Cant pop and slice first second element

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();}
}

Wrong counting and thinking, try:

if (maxtrack>0){

Thank's Evertjan, unfortunately it is not it. I suspect something goes wrong out side function, i really do not get it because after i set to zero. I still can't remove the two last tracks but they are visually written out, but they can't be there because tracknr = maxtrack is down at zero. I will have to check what is going on elsewhere, because the maxtrack and tracknr goes down to zero but the two tracks still written out. I have to check track.length with console.log.

Well you did not show us how you came to maxtrack,
you should do this:

maxtrack = track.length - 1;

and test it in each case, NOT:

maxtrack--;

> I suspect something goes
> wrong out side function, i really do not get it because after i set to

(maxtrack>1)

will in my example return false if maxtrack is either 1 or 0,
so ALSO if there are TWO members of the array left.

> I still can't remove the two last tracks but they are visually

You must mean "tracknr == maxtrack" 
and that NEVER returns zero or any other number, 
only true or false.

NO. Debugging is fine, but should not come in the place of decent code 
writing.

Please stop using outside variables in a funtion to be tested,
since then you cannot test such function outside the context,
which makes interpretation of the debugging process a nightmare.

Try this as a test:

=========================

<script>

function removeTrack(trackNr, trackArray) {
	let maxTrack = trackArray.length - 1;
	if (maxTrack>0) { 
		if (maxTrack==trackNr) {
			trackArray.pop();
		} else {
			trackArray.splice(trackNr, 1);
		};
	};
	console.log('now:', trackArray);
};

let myTrackArray = ['one', 'two', 'three', 'four', 'five' ];
console.log('start:', myTrackArray);

</script>

<button onclick='removeTrack(1, myTrackArray)'>Remove second</button>
and look in console.

=========================

NOW change in the above:

if (maxTrack==trackNr) {

to:

if (false) {

and conclude that the seperate pop() is unnecessary.

Aren't you avoiding the problem a bit Evertjan, isn't the problem also position the tracknr after remove, so you nned the popcase? Because you must remove 1 from tracknr? Or am i wrong? Basicly if i pop "active track" tracknr--. But if there is elements after i can just remove it because i can have same "active track?"

Well i could always set tracknr to 1 after remove.

This script always have an active track it listens to, "send channelmessages ,programmessages, and notes to". So something should be there but maybe set active tracknr to 1 work just as good after remove.

I just put "active track" as a global variable and called it tracknr, maybe not ideal...

I don't know or understand the purpose of your "track", 
but that seems unimportant:

For solving your coding problem, the manipulation of the "tracknumber" [I 
would say "array-index"] is unimportant, so in TESTING your function as a 
black box, better leave it out for the moment.

If the test shows your black box/function works as planned, you can always 
introduce thiis again in your application code.
