Question

I have a line of code on the server that I want to move to the client page in javascript.

string ThePhone = "1234567890";
string ThisFormat = Regex.Replace(ThePhone, @"(\d{3})(\d{3})(\d{4})", "$1-$2-$3");

It’s supposed to return 123-456-7890. How can I change this to javascript?

Thanks.

Answer 1

It is almost exactly the same in this case:

phone = phone.replace(/(\d{3})(\d{3})(\d{4})/, '$1-$2-$3');

Notes:

• You need the /g flag (/.../g) if the string may contain more than one phone (but then we may also want \b)
• \d in .Net matches all Unicode digits, in JavaScript it only matches [0-9].
