function transform(array, f) {
    var ret = [];
    $.each(array, function(index) {
        var v = f.call(this, index);
        if(v) {
            ret.push(v);
        }
    });
    return ret;
}

var result = transform(
    [{"nomeDominio":"gggg.fa"},{"nomeDominio":"rarar.fa"}], 
    function() { return this.nomeDominio; }
);

alert(result.toString());
