just give me the damn emails.

getemails.js

var emailEls = $('tr td:last-child').filter(function(){ 
  return $(this).html().length > 0;
});

var email;
var emails = [];
$.each(emailEls, function(k,v){
  email = $(v).text();
  
  if ( $.inArray( email, emails ) === -1 ){
    emails.push( email );
    console.log( email );
  }
});

emails.length;
