Limpiar Selects Dependientes

[saulvr91]

Disculpen me gustaría limpiar mis selects, l accación que quiero haces es que al momento de dar click en el primero me limpie todos y de paso la búsqueda que hace.

Código PHP:

 <form class="form-horizontal" id="formdependiente"> 
                                                    <label></label> 
                                                    <select name="ano"  class="selectdepend" id="ano"> 
                                                    <option value="">-Seleccionar año-</option> 
                                                    <?php while($r= mysql_fetch_object($c)){ 
                                                    echo "<option value=".$r->id.">".$r->name."</option>"; 
                                                   } ?> 
                                                    </select> 
                                                     
                                            </div> 
                                            <div class="col-md-6"> 
                                                <div class="form-group">  
                                                     <label></label> 
                                                    <select name="marca" class="selectdepend" id="marca"> 
                                                    <option value="">-Seleccionar marca-</option> 
                                                    </select > 
                                            </div> 
                                        </div> 
                                         
                                      
                                             <div class="col-md-6"> 
                                                <div class="form-group">  
                                                    <select name="modelo" class="selectdepend" id="modelo"> 
                                                    <option value="">-Seleccionar modelo-</option> 
                                                    </select>  
                                            </div> 
                                        </div> 
                                             <div class="col-md-6"> 
                                                <div class="form-group">  
                                                    <select name="motor" class="selectdepend" id="motor"> 
                                                    <option value="">-Seleccionar motor-</option> 
                                                    </select>  
                                            </div> 
                                        </div>

Claro este es el java

$(function(){
$("#marca,#modelo").attr('disabled',true);
function ejecutar(obj1,obj2,task){
$('<img/>', {
'class': 'loading',
src:'loading.gif',
'style':'display:inline'
}).insertAfter(obj1);

$.ajax({
type:"POST",
url:"action.php",
dataType:"html",
data:"task="+task+"&id="+$(obj1).val(),
success:function(msg){
$(obj1).next('img').remove();
$(obj2).html(msg).attr("disabled",false);
},
error:function(jqXHR,textStatus,errorThrown){
$(obg1).next('img').remove();
alert("Error al ejecutar => "+textStatus+" - "+errorThrown);
}
});
}
$("#ano").change(function(e){
$("#modelo,#marca").attr('disabled',true);
if($(this).val().trim()!=""){
ejecutar($(this),$("#marca"),"getmarca");
}
});
$("#marca").change(function(e){
$("#modelo").attr('disabled',true);
if($(this).val().trim()!=""){
ejecutar($(this),$("#modelo"),"getmodelo");
}
});
$("#modelo").change(function(e) {
$("#motor").attr('disabled', true);
if ($(this).val().trim()!="") {
ejecutar($(this), $("#motor"), "getmotor");
}
});

$("#motor").change(function(e) {
$("#producto").attr('disabled', true);
if ($(this).val().trim()!="") {
ejecutar($(this), $("#producto"), "getproducto");
}
});


});

Código Javascript:

$('#modelo').html('');
$('#modelo').APPEND("<option value=''>-Seleccione modelo-</option>");
$('#motor').html('');
$('#motor').APPEND("<option value=''>-Seleccione motor-</option>");
