It's line 4 of this part of fivestar.module:
$options = array('-' => t('Select rating'));
for ($i = 1; $i <= $element['#stars']; $i++) {
$this_value = ceil($i * 100/$element['#stars']);
$options[$this_value] = t('Give @title @star/@count', array('@title' => $title, '@star' => $i, '@count' => $element['#stars']));}
It creates a verbose title on every star. I tried this javascript
var elements = document.getElementsByTagName('a');
for (var i = 0, len = elements.length; i < len; i++)
{
elements[i].removeAttribute('title');
}
but it doesn't affect these links. I even tried doing it inline at the bottom of html.tpl. Is there a function I can use in template.php? Full file if it helps.
