[jQuery] selectbox: change selected item

[zenx]

Hi,

I don't know how to change the selected item in a selectbox. I tried
this but it doesn't work as expected.

HTML code:
=========
<select id="id_cliente" name="cliente" size="1">
    <option value="" selected="selected">---------</option>
    <option value="1">First</option>
    <option value="2">Second</option>
</select>

javascript code:
============
var cliente = 2;
$('#id_cliente:nth-child(cliente)').attr('selected','selected');

any ideas?

Thank you!
