validate a 10 digit USA style phone number using a Regular Expression in Javascript
I want to validate a 10 digit USA style phone number using a Regular Expression in Javascript
It should allow (validate as correct) the following formats:
xxx-xxx-xxxx
215-121-1247
It should reject as invalid:
8059311142
805 931 42ab
105 931 4288
I found a regex to implement this below, but I can't get it to work.
/^\(?([0-9]{3})\)?[-. ]?([0-9]{3})[-. ]?([0-9]{4})$/
please help me on this

You can very simply do it as:
^\d{3}-\d{3}-\d{4}$
