Submit login form using Ajax - Joomla! Forum - community, help and support

i need submit form below (components/com_users/views/login/tmpl/default_login.php. ) using ajax. (i'm new ajax , php, javascript area).

code: select all

   <form action="<?php echo jroute::_('index.php?option=com_users&task=user.login'); ?>" method="post">

      <fieldset>
         <?php foreach ($this->form->getfieldset('credentials') $field): ?>
            <?php if (!$field->hidden): ?>
               <div class="login-fields"><?php echo $field->label; ?>
               <?php echo $field->input; ?></div>
            <?php endif; ?>
         <?php endforeach; ?>
                         ......
   </form>

my ajax request come external mobile app (on click, run javascript ajax submit form).

is possible? if yes, parameters should pass ajax request (based on example here : "http://stackoverflow.com/questions/16616250/form-submit-with-ajax-passing-form-data-to-php-without-page-refresh" need pass url, data , success).

if possible, i'm able pass username , password (which form fetch them fieldset), can provide them in plain text (no security concerts that).

deeply appreciate help.
