In as3 is there a way to check Textinput isnt number?

Question

I need to check if the text input contains anything that isnt int(number), wondering if it is possible.

if (!isNaN(s1.range))) {
        s1.tet.text = "Please enter fields that only contains number";

I tried putting (s1.rangelow !== [Number])) but it gives me an error comparison between a value static type to an possibly unrelated type Array — Benyaman, Jun 18 '14 at 08:45
I tried that too, that won't let anything thru, even the input are numbers i also tried (!(s1.rangelow is int)) — Benyaman, Jun 18 '14 at 09:03
I read that in this thread it might not be possible? http://www.actionscript.org/forums/showthread.php3?t=211012 — Benyaman, Jun 18 '14 at 09:04

If you need to check a text (String) to contain non digits, I would personally use RegExp. It would be easier for you to test the string against a regular expression.

Here's a simple example that will check for anything that is not a digit

var str:String = "04.sdf..";
var re:RegExp = /[\D]/g;
trace(str.match(re).length); // 6

In this example there are 6 char's that are not digits, therefor we can show an error to the user.

Here's a good tutorial on RegExp if you believe it can be helpful to you:

An aside - you can restrict what characters can be entered in a TextField using the "restrict" property. Docs here: http://help.adobe.com/en_US/as3/dev/WS8d7bb3e8da6fb92f-20050207122bd5f80cb-7ff6.html — Plastic Sturgeon, Jun 20 '14 at 17:45
