what is the reg exp to do this?

[laredotornado@zipmail.com]

Hi,

I want to create a regular expression that will take a single input
name field and save the first and last names to two separate js vars.
The criteria for determining what is the separation would be the first
occurrence of a space (ascii code = 32). However, note that a user
may only enter one word or nothing at all. If the DOM id for the
field I want to parse is "nameField" , how would I do this?

Thanks, - Dave

Why are you making it harder than it has to be?

var theNames = refToFormElemen t.split(' ');

If theNames has a length of 1, then there was no space.
If theNames has a length of 2, then there was a space.
If theNames has a length 2, then there was more than one space.

var fullname=docume nt.getElementBy Id("nameField") ;
var firstSpace=full name.indexOf(' ');
WScript.Echo(
"First Name:"+fullname .substr(0,first Space)
+"\nLast Name:"+fullname .substr(firstSp ace+1)

A= String.split(/\s+/);AA=A.length;
firstName=AA<2? "":A[0];
lastName=AA==1? A[0]:AA>1?A.slice(1 ).join(" "):"Empty";
