Reset to default 3You can go like
$("select[name='_users_id_requester'] option").not(":eq(1)").val('');
$("select[name='_users_id_requester'] option").not(":eq(1)").prop('value', '');
You can use some selectors to select precisely do what you want as the :nth-child
and the :not
one.
$("select[name='_users_id_requester']").find('option:not(:nth-child(2))').each(function(){
$(this).attr("value", "");
});
The :nth-child
selects a precise child and the :not
do a sort array subtraction. It subtracts all the ones match by the not the with the whole array.
Here is a working JsFiddle. Just look at the HTML using Chrome or Firebug
