Javascript RegExp - extract phone numbers from string

Question

I have the following working regex to extract a lot of phone numbers in different formats.

var regex = new RegExp(
            "\\+?\\(?\\d*\\)? ?\\(?\\d+\\)?\\d*([\\s./-]?\\d{2,})+",
            "g"
        );
....

(If the script didn't load, press the "Run" button from the top menu)

As you can see in the example (by following the link), the last 2-3 phone number formats (var phoneNumbers) doesn't match the used regex. You can test the regex modifying it in the script and running it.

So i need a regex that match all the enumerated phone number formats (to extract them from an entire webpage (document.body.innerHTML)).

I don't know how prescriptive you want to be, but this matches all your examples:

var regex = new RegExp("\\+?\\(?\\d*\\)? ?\\(?\\d+\\)?\\d*([\\s./-]?\\d{2,})+", "g");

See a live demo of this regex.

One small bug with your regex: When wanting to include a literal dash in a character class, either escape it or place it first or last.

You had [\\s-.], which is incorrect. It should be either [\\s.-], [-\\s.] or [\\s\\-.].

Thank you for your help @bohemian. Actually i forgot to mention that i didn't want to extract the country code, too. But this helps me a lot. If you can post me another regexp to extract the phone number without the country code, will be the best. And thanks for the remarks, too.

Ok, i change my code to work with the country codes. Only for the curiosity, can you provide the new regex to exclude the country codes? Thanks a lot!

I have to remark a problem, in the live demo you provided, all the strings were matched, but when i run the above provided script, the next strings doesn't match: (0490)260722 (0)442207724 +33 (0)442207724 Can you help me with this?

I can help with vountry cides, but what exactly do you mean by "exclude"? I will look into your new examples.

I have looked into your new examples you're having problems with. I tried them and they match for new: See live demo. Tell me more about how/what you're matching
