Extract all email addresses from bulk text using jquery

Question

I'm having the this text below:

[email protected], "assdsdf" <[email protected]>, "rodnsdfald ferdfnson" <[email protected]>, "Affdmdol Gondfgale" <[email protected]>, "truform techno" <[email protected]>, "NiTsdfeSh ThIdfsKaRe" <[email protected]>, "akasdfsh kasdfstla" <[email protected]>, "Bisdsdfamal Prakaasdsh" <[email protected]>,; "milisdfsfnd ansdfasdfnsftwar" <[email protected]>

Here emails are seprated by , or ;. I want to extract all emails present above and store them in array. Is there any easy way using regex to get all emails directly?

Answer 1

Here's how you can approach this:

HTML

<p id="emails"></p>

JavaScript

var text = '[email protected], "assdsdf" <[email protected]>, "rodnsdfald ferdfnson" <[email protected]>, "Affdmdol Gondfgale" <[email protected]>, "truform techno" <[email protected]>, "NiTsdfeSh ThIdfsKaRe" <[email protected]>, "akasdfsh kasdfstla" <[email protected]>, "Bisdsdfamal Prakaasdsh" <[email protected]>,; "milisdfsfnd ansdfasdfnsftwar" <[email protected]> datum eternus [email protected]';    

function extractEmails (text)
{
    return text.match(/([a-zA-Z0-9._+-]+@[a-zA-Z0-9._-]+\.[a-zA-Z0-9._-]+)/gi);
}
     
$("#emails").text(extractEmails(text).join('\n'));

Result

[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected]

Answer 2

You can use this regex:

var re = /(([^<>()[\]\\.,;:\s@\"]+(\.[^<>()[\]\\.,;:\s@\"]+)*)|(\".+\"))@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))/g;

You can extract the e-mails like this:

('[email protected], "assdsdf" <[email protected]>, "rodnsdfald ferdfnson" <[email protected]>, "Affdmdol Gondfgale" <[email protected]>, "truform techno" <[email protected]>, "NiTsdfeSh ThIdfsKaRe" <[email protected]>, "akasdfsh kasdfstla" <[email protected]>, "Bisdsdfamal Prakaasdsh" <[email protected]>,; "milisdfsfnd ansdfasdfnsftwar" <[email protected]>').match(re);

//["[email protected]", "[email protected]", "[email protected]", "[email protected]", "[email protected]", "[email protected]", "[email protected]", "[email protected]", "[email protected]"]

Answer 3

Just an update to the accepted answer. This does not work for "plus" signs in the email address. GMAIL supports [email protected].

I've updated to:

return text.match(/([a-zA-Z0-9._+-]+@[a-zA-Z0-9._-]+\.[a-zA-Z0-9._-]+)/gi);

The bellow function is RFC2822 compliant according to Regexr.com

ES5 :

var extract = function(value) {
   var reg = /[a-z0-9!#$%&'*+/=?^_`{|}~-]+(?:\.[a-z0-9!#$%&'*+/=?^_`{|}~-]+)*@(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])?/g;
   return value && value.match(reg);
}

ES6 :

const reg = /[a-z0-9!#$%&'*+/=?^_`{|}~-]+(?:\.[a-z0-9!#$%&'*+/=?^_`{|}~-]+)*@(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])?/g
const extract = value => value && value.match(reg)
