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

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";

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:
