javascript - regex extract email from strings

Question

I want to know if by using regular expressions I am able to extract emails from the following strings?

The following RE pattern is .*@.*match with all strings. It has worked fine with some of the string, though with not all.

I want to match all strings match with email pattern include all domain like (some-url.com) or (some-url.co.id)

Answer 1

You can create a function with regex /([a-zA-Z0-9._-]+@[a-zA-Z0-9._-]+.[a-zA-Z0-9_-]+)/ to extract email ids from long text

function extractEmails ( text ){
    return text.match(/([a-zA-Z0-9._-]+@[a-zA-Z0-9._-]+.[a-zA-Z0-9_-]+)/gi);
    }

Script in action: Run to see result

var text = `boleh di kirim ke email saya [email protected] tks... boleh minta kirim ke [email protected]. [email protected]. .
