Extract all email addresses from bulk text using j

Question

I'm having the this text below:

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

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

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)

function GetEmailsFromString(input) {
  var ret = [];
  var email = /\"([^\"]+)\"\s+\<([^\>]+)\>/g

  var match;
  while (match = email.exec(input))
    ret.push({'name':match[1], 'email':match[2]})

  return ret;
}

var str = '"Name one" <[e-mail]>, ..., "And so on" <[e-mail]>'
var emails = GetEmailsFromString(str)

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:

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

//["[e-mail]", "[e-mail]", "[e-mail]", "[e-mail]", "[e-mail]", "[e-mail]", "[e-mail]", "[e-mail]", "[e-mail]"]

Answer 4

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

I've updated to:

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

Answer 5

You don't need jQuery for that; JavaScript itself supports regexes built-in.

Have a look at Regular Expression for more info on using regex with JavaScript.

Other than that, I think you'll find the exact answer to your question somewhere else on Stack Overflow - How to find out emails and names out of a string in javascript

Answer 6

Here's how you can approach this:

HTML

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

JavaScript

var text = '[e-mail], "assdsdf" <[e-mail]>, "rodnsdfald ferdfnson" <[e-mail]>, "Affdmdol Gondfgale" <[e-mail]>, "truform techno" <[e-mail]>, "NiTsdfeSh ThIdfsKaRe" <[e-mail]>, "akasdfsh kasdfstla" <[e-mail]>, "Bisdsdfamal Prakaasdsh" <[e-mail]>,; "milisdfsfnd ansdfasdfnsftwar" <[e-mail]>';    

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

[e-mail] [e-mail] [e-mail] [e-mail] [e-mail] [e-mail] [e-mail] [e-mail] [e-mail]
