  why does .match for regular expression always returns null

  Jul 09, 2012 12:30 AM|LINK

  Hi,

  I have a regular expression var regex which is returned as "^([1-9]\d{8})$"

  When I use value.match(regex); ... value.match is always returning null.

  I read somewhere the the regex shouldnt be a string and I should replace the " with /

  However, I don't know how I can do this as regex.replace(""", "/") doesn't seem to work.

  How can I use this replace method?

  Please any help and examples on this would be very much appreciated.

  Thank you
