Regular Expression javascript for cip code [closed]

Question

I need this regular expression for this format

(##.####)

I think it should be something like this

/[0-9]*[.][0-9]/

I dont have any strong idea. i think i should be like this /[0-9]*[.][0-9]/
@fnkr: XRegExp is a lib, not the native JS RegExp constructor. Besides, for something this easy, there really isn't a need to overcomplicate things IMO

I'll bite. This should work:

var re = /(^\d{2}\.\d{4}$)/;

(^    - begin
\d{2} - match two digits
\.    - the period between digit sets
\d{4} - match four digits
$)    - end

And if you need the parantheses:

var re = /(^\(\d{2}\.\d{4}\)$)/;

I assume, that the brackets does not belong to the pattern.

Use the quantifier {x} where x is the number of repetitions you want to find. With \d you can match a digit.

The next important point is, you need to anchor your regex to avoid getting partial matches:
