How to write regular expression for this case?

[zbx888]

I want to use Javascript to validate user input for last name and first name by regular expression and just allow usa alphebetical letters plus space, apostroph and hyphen such as O'Neill and Lacova-D'elia.

How to write regular expression to validate user's input? Thanks a lot!

the RE by itself should be something like...

/[a-zA-Z\-\'\s]/g

*cLFlaVA
----------------------------
[tt]( <P> <B>)¹³ * (<P> <.</B>)[/tt]

I wouldn't use \s. I'd use a literal space. \s includes ANY WHITESPACE, including tab, linefeed and carriage return. Although in a single-line textbox you shouldn't encounter the latter two, the former is a possibility. It pays to be precise about what you want.
