ajax - Get JSON data from a PHP file to jQuery and put it on selectbox -

i have big problem here. want receive data php file.

i this:

$("#id_categoria").change(function(){     var id = $(this).val();     $.ajax({         type: "post",         url: "<?php echo root . '/control/functions.php'; ?>",         data: "action=getsubbycat&id="+id,         success: function(data){             alert(data);         }     }); }); 

alert(data) returns [{"id_subcategoria":"1","nome":"port\u00e1teis"},{"id_subcategoria":"2","nome":"desktop"}].

and how can consume this? , put in <option value="2">desktop</option>?

and why portáteis equal port\u00e1teis? because database in utf-8?

you use parsejson turn string json object, either build object insert dom using jquery, or document.write() desired output.
