September 2nd, 2009 Marvin Blase

This article shows how you can easily check if a specific value already exists in an Array in Actionscript 3.

Actionscript:

PLAIN TEXT

Actionscript:

1. var doesExist:Boolean;
2. var rndInt:int;
3. var rndArr:Array = new Array();
4.  
5. var timer:Timer = new Timer(200, 15);
6.     timer.addEventListener(TimerEvent.TIMER, fillArray);
7.     timer.start();
8.  
9. function fillArray(event:TimerEvent):void {
10.     rndInt = Math.floor(Math.random() * 15);
11.     doesExist = rndArr.every(checkExisting);
12.     doesExist ? rndArr.push(rndInt) : fillArray(null);
13.     trace(rndArr);
14. }
15.  
16. function checkExisting(element:*, index:int, arr:Array):Boolean {
17.     return (element != rndInt);
18. }

   Why not just use the "indexOf" method of an Array? Returns -1 if a value doesn't exist in the array, or the index position if it does.
