Yammer: get email addresses of group members

yammer-group-emails.js

/*
 * Get email addresses of Yammer group members
 * -------------------------------------------
 *
 * This script works only when everyone in your organization 
 * has an email of type <FIRSTNAME>.<LASTNAME>@<YOUR-ORGANIZATION-DOMAIN>
 * AND
 * everyone in your Yammer organization uses real names  
 * (and therefore have username of type <FIRSTNAME><LASTNAME>)
 *
 * 1. Go to Yammer Group
 * 2. Open Group members modal window
 * 3. Edit your organization name and domain for emails in this script
 * 4. Run this script in (Chrome/Firefox etc) DevTools
 *
 */

// Edit these:
var organizationName = '<YOUR-YAMMER-ORGANIZATION-NAME-HERE>';
var emailDomain = '<DOMAIN-USED-FOR-EMAILS>';

// Works because Yammer has jQuery in it
$('.username a').each(function(){

  var userLink = $(this).attr('href');
  var userName = userLink.substring(String('https://www.yammer.com/'+organizationName+'/users/').length, userLink.length);

  var firstName = this.text.substring(0, this.text.indexOf(' '));
  var lastName = this.text.substring(this.text.indexOf(' ')+1, this.text.length);

  var slugifiedFirstName = userName.substring(0, firstName.length);
  var slugifiedLastName = userName.substring(firstName.length, userName.length);

  console.log(slugifiedFirstName+'.'+slugifiedLastName+'@'+emailDomain);
});
