Error checking input text fields.

Question

Hi
Just wondering where I find a list of what can be error checked in input text fields?
I'm looking for things like...
- checking that letters and not numbers are entered
- checking that an entered number is in a certain range
etc...
Thanks guys
Shaun

To restrict input for a text field, use the following AS3 codes:
myInput.restrict = "A-Z, a-z, ., ,'"; //myInput is the instance name of your text area
To check the range of the numbers, use the following code:
myInput.restrict = "0-9";
myInput.maxChars = 3;
myBtn.addEventListener(MouseEvent.CLICK, chk);
function chk(e:MouseEvent):void
    var myString:String = myInput.text;
    var i:Number = Number(myString); //Converting the string to a number variable
    var max:Number = 100; //Maximum range
    var min:Number = 30; //Minimum range
    if (i < max && i > min) //Condition to indicate the range
        trace("Within range");
    else
        trace("Out of range");
Hope this helps.
