What would the reg expression be for a string of 13 consecutive digits

Do you mean a string matching exactly 13 digits?

/^\d{13}$/

Or, a string containing a 13 digit sequence?

/\d{13}/

Or, string starting with 13 consecutive digits?

/^\d{13}/ (What you showed in your post.)

This has nothing to do with Rails, and should be asked on a JavaScript
forum.

Best,
