Ajax with multiple submit buttons
===

How can I change the code below so instead of a text input type with a submit button I want multiple submit buttons each with their own unique value? Everything I try just ends up with submit's value being undefined. Any help would be great!

    <script type="text/javascript">
                        $(function() {
                            $("#lets_search").bind('submit',function() {
                                var value = $('#str').val();
                                $.post('db_query.php',{value:value}, function(data){
                                    $("#search_results").html(data);
                                });
                                return false;
                            });
                        });
                    </script>
        
        <form id="lets_search" action="" >
                        Search:<input type="text" name="str" id="str">
                        <input type="submit" value="send" name="send" id="send">
                     </form>
