Regex for phone number

[user1980]

hello...

I am trying to write regular expression for the phone numbers to be in the format..

(000) 000-0000 and (000)000-0000
the difference being space after brackets.
I have used this expression and it did not work..I think I am missing a pace or brackets..unabl e to figure...

var phoneREX = /^\(\d\d\d\) \d\d\d-\d\d\d\d | \(\d\d\d\)\d\d\d-\d\d\d\d$/;

this phrase does not validate both the formats..
can somebody please tell me the correct phrase..thank you

You can use the ? Character for optional matching, i.e. matching both a space and no space.

Tip: you can use \d{3} to match 3 numbers.

hello
thank you for the response..

I did try this but seems like it does not work...it does not valdiate anything

 var phoneRE = /^?(\(\d{3}\)\d{3}-\d{4}|(\(\d{3}\)\s\d{3}-\d{4}))$/;

thank you

The ? Character goes after the optional part (in this case space). Then you don't need the | character and all the redundant characters after it.
