Validate multiple email addresses separated by a comma

[lbless1]

This code is not validating any email addresses after the first one. Any help would be appreciated!

function onChange(control, oldValue, newValue, isLoading, isTemplate){

  var err_field = control.id;

  var err_flag = 'false';

  var err_message = 'Invalid Email Address format. Format should be like: abc@domain.com';

  var group_members = g_form.getValue('str1');

  var member_split = group_members.split(',');

  for (var n = 0; n < member_split.length; n++) {

  var member_info = member_split[n];

  regex = /[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}/ig;

  err_flag = regex.test(g_form.getValue(err_field));

  g_form.hideErrorBox(err_field);

  if (!err_flag) {

    g_form.hideFieldMsg('req_inbox');

  g_form.showFieldMsg(err_field, err_message, 'error');

  }

  else {

  g_form.hideErrorBox(err_field);

  }

}

}

function onChange(control, oldValue, newValue, isLoading, isTemplate){

  var err_field = control.id;

  var err_flag = false;   // Made binary instead of string by removing quotes

  var err_message = 'Invalid Email Address format. Format should be like: abc@domain.com';

  var group_members = g_form.getValue('str1');

  var member_split = group_members.split(',');

  for (var n = 0; n < member_split.length; n++) {

      if (!err_flag) {

          g_form.hideFieldMsg('req_inbox');

          g_form.showFieldMsg(err_field, err_message, 'error');

          err_flag = false; // Reset the flag once you perform the action you would like.

      }else {

          g_form.hideErrorBox(err_field);

      }

  }

}

Still does not validate after the first in the series.

Still does not validate after the first in the series. Plus, leaves the error message even is the first in series is correct.

What if there is a space after the comma?     The system may see that as one continual string
