i want receive data using ajax. when use code, result prints [object htmlinputelement]. can change object string?

here's code in jsp use ajax.

$('select#product').change(function() {          var param = "code=" + $('#product').val();          $.ajax({             url : 'add_products/add_products.jsp',             contenttype : "application/x-www-form-urlencoded; charset=utf-8",             data : param,             type : 'post',             datatype : 'text',             success : function(data, textstatus, jqxhr){                 $('#color').val(color);                 $('#price').val(price);             }         });     }); ... <td>     <input type="text" id="color" class="form-control" name="color"  /> </td> <td>     <input type="text" id="price" class="form-control" name="price" value="0"  /> </td>

product_code = request.getparameter("code");  try {     query = "select * new_product product_code='"+product_code+"'";     rs = stmt.executequery(query);     while (rs.next()) {         size = rs.getstring("sizes");         color = rs.getstring("color");         price = rs.getstring("price_cny");          out.println(color);         out.println(price);      } } catch (sqlexception e) {     out.println(e); } { } 

thanks.

change server code this...

product_code = request.getparameter("code");  try {     query = "select * new_product product_code='"+product_code+"'";     rs = stmt.executequery(query);     while (rs.next()) {         size = rs.getstring("sizes");         color = rs.getstring("color");         price = rs.getstring("price_cny");          out.println(color+"_"+price);                //concatenate 2 values      } } catch (sqlexception e) {     out.println(e); } { } 

and client code this...

$('select#product').change(function() {          var param = "code=" + $('#product').val();          $.ajax({             url : 'add_products/add_products.jsp',             contenttype : "application/x-www-form-urlencoded; charset=utf-8",             data : param,             type : 'post',             datatype : 'text',             success : function(data, textstatus, jqxhr){                 var values = data.split("_");       //get 2 values seperated                 $('#color').val(values[0]);                 $('#price').val(values[1]);             }         });     });
