jQuery selection help

    jQuery.subscribe('setIdComFamOnEditForm', function(event,ui) {
        var idButton = ui.id;
        var idComFam = jQuery("#" + idButton).name.split("-")[1];
        $("#fo开发者_开发知识库rmFamigliare").attr('action', 'detraz_update');
        $("#IdComFam").val(idComFam);
    });

The above code does not find the jQuery("#" + idButton).

Where Am I wrong?

I'm not that familiar with subscribe but are you sure that ui.id is returning a value? Furthermore I don't think a jquery wrapped set has a name property. So I don't think jQuery("#" + idButton).name will work. If you want the name attribute you would need to use the attr() method.
