Hi everyone
I have a problem validating the phone number. I want to do 2 main things when validating and IT MUST BE DONE inside
<script></script> tags
<script>
1) Check to see if the values entered are numbers, if not then focus back to the field
2) if they are numbers i want to make sure that the area code is 3 digits long the prefix is 3 digits long and the suffix is 4digits
long. all 3 of these parts of phone number are entered in different text boxes
generally the phone #'s look like xxx-xxx-xxxx
</script>
so if anyone can help me, I will really really really appreciate it
Thanks

Neetu --
Sounds like you're going to want to use client-side JavaScript
to perform your validation. I would suggest taking a look at using
the built in regular expression object available in JS. Once you
gain some familiarity working with them, regular expressions are
extremely fast and flexible in handling all your validation needs.
If you don't want to deal with having to familiarize yourself with
REs and their special syntax, you could certainly just perform a
series of string validation techniques in JS...
