There are many examples online. Have you tried searching yet?

Start here for
var pat=new RegExp("^[0-9]$"); // create your regex pattern here document.write(pat.test("121231")); // this simply checks for digits in any order in any length
As Jeanne pointed out, phone number varies in region-wise , code your regex
() like the code above.
