What's the equivalent of getSelected() (mootools 1.1)

Question

In mootools 1.2, getting selected options in a multi select is easy using getSelected:

// code 1
$('my_select').getSelected().each(function(opt) { 
    // stuff
});

Is there an equivalent of that in mootools 1.1 or do I have to use getChildren() and check whether it has been selected?

What I have at the moment:

// code 2
// get all options
$('my_select').getChildren().each(function(g) {
    // if option is selected
    if(g.selected == true)
    {
       // do some stuff
    }
});

Answer 1

$('my_select').getSelected() is in 1.2.4 right? Not sure if it's 1.1. if not you can try

$$('#my_select option').filter(function(option){ return option.selected; })

If filter does not exist, to bad. :( you have to do it manually...
