Remove from associative array

[The Little Guy]

I have an array that could look simular to this:

playersArr = Array(1 => 'cat', 3 => 'fish', 9 => 'bird', 5 => 'mouse');
function removePlayer(id){
playersArr.splice(id,1);
}

 

Then there is a function, that is supposed to remove an element from the array (removePlayer).

 

I then have a button next to each one to remove it from the array. So if you want to remove one you press the button and it fires up removePlayer() and removes that id from the array.

 

The problem is that if I remove from the array 1, 3, 9, 5 in that order (one at a time) it will remove all but #5.

But...

If I remove from the array 5, 9, 3, 1 in that order (one at a time) it will remove them all.

 

does that make any sense???

What's wrong with "delete"?

[The Little Guy]

Thank You! Never though of that... Not even sure I knew there was a delete

[The Little Guy]

If I have 1 key value pair, and I delete it.

 

why does it still think it is in there?

 

if I alert(playersArr.length); it says 2 (1 key 1 value = 2)

That's quirky because you're using integers as hash keys... associative array in JS are funny.

Any Ideas?

Sure... don't use integers, or prefix them with underscores.
