Simple equality check not working

[basil01]

Hi

one of my students has an error, and I can't see it.

He has a input text box (a), and he's looking to check that the user enters "one". If they get it right, it displays a message in dynamic text box (b)

var x:String = "one";

btn_done.onPress = function(){

  if (a.text != x){

  b.text="Wrong";

  trace(a.text);

  }

  else{

  b.text = "Right";

  }

}

No matter what one types, the response is "wrong". I've spent hours looking, but can't see the problem. Can anyone shed some light please?

change the textfield from multiline to single line.

(when a text trace look like you expect but doesn't act the way you expect, trace its length, too.  that will reveal white space problems.  in your case you probably have a carriage return at the end of "one".  ie, "one\r".)

How do you trace the length?

[kglad]

strings have a length property:

var x:String = "one";

btn_done.onPress = function(){

  if (a.text != x){

  b.text="Wrong";

trace(a.text+" "+a.text.length);

  }

  else{

  b.text = "Right";

  }

}
