InputField("tFName", /^[a-zA-Z-\-\ ]+$/);

A:
Hyphen is already included (twice), you can add the apostrophe by just editing it into the character class:
/^[a-zA-Z-\-\ ']+$/
You can rewrite it to look like this, so that theres no need for escaping the hyphen and it's only included once:
/^[a-zA-Z '-]+$/

could try `/^([a-zA-Z]|(\-*)|(\'*))+$/`

That did not work it escaped the hyphen but not the apostrophe.

@Moja Ra not sure at what point you tried, I edited the regex so might want to take another look.

It is not allowing the apostrophe the way it is written /^([a-zA-Z]|(\-*)|(\'*))+$/

I am able to escape the hyphen but I am still not able to escape the apostrophe in this regular expression for javascript.

just another option... I'd try this myself but I dont have a way to test it on this computer at the moment. `/^([a-zA-Z]|(\-*)|['])+$/`

That did not work either.

@Moja Ra alright, I'm sorry I wasn't able to help further. After I get home I will test some options and post back here if you don't have an answer yet.

@Moja: the regular expression I gave you works just fine - I added an example to my answer.

A:
Try this:
"abc'def ghi-jkl mno-pq'rst".match(/^[\w\s-']+$/)
\wfor any letter\sfor space-for hyphen'for apostrophe

`\s` will match more than just space - `\t\r\n`, among others, are also included. Also, `\w` will match `_`.

@andy It is quite hard to get a \t\r\n in an input field but ok for the \w and _
Mic

@Mic: it's easier than you think, you'd be surprised how many people accidentally highlight an `\n` or `\r\n` when copy-pasting ;-) Although, that is what trimming is for.
Andy E

@andy Sure? I thought the \n\r were removed automatically from the value attribute of an INPUT.
Mic
2010-09-07 18:26:25
@Mic: of course, you are right - it is still possible to paste a \t though ;-)
