Thanks, I already know them (thankfully, I can say, after previous
projects).

Good luck!

A word character [A-Za-z_0-9]

Excellent! thanx a million - where can i find these regular expression i
would like the check to check for non alpha numerics

so it would be something like

> function keyCheck(e){
	var keyChar =3D3D String.fromCharCode(e.which);
	if((keyChar.search(/\D/) !=3D3D -1) && (keyChar.search(alpha reg
expr)! =3D3D -1){
		alert(One of the characters isn't alpha numeric");
	}
}

thanx a million
Noreen



> The 3D is just a mess-up in WROX mailing lists.
Just remove all instances of 3D.

The RegExp is looking for anything that isn't a digit.
If it finds anything the alert pops up.

hi robert

confused by 3D string? - is this just a var instance or?
also the reg expr u search for /\D what does this equate to?

thanx
noreen

> function keyCheck(e){
	var keyChar =3D3D3D3D String.fromCharCode(e.which);
	if(keyChar.search(/\D/) !=3D3D3D3D -1){
		alert(One of the characters isn't a number");
	}
}

=3D3D3DC4mne: [javascript_howto] checking for nonalpha numeric 
characters


hi

i am trying to check each character entered and make sure it is only
an=3D3D3D20 alpha-numeric char

function keyCheck(e){
	var keyChar =3D3D3D3D String.fromCharCode(e.which);
	//here is where u would have to check the key then
}

document.captureEvents(Event.KEYPRESS);
document.onkeypress =3D3D3D3D keyCheck;

i know in Java u can use char.isLetterorDigit(myString.charAt(index))

but how can this be done in javascript??

thanx
