Naturally, I figured it out after posting...
Working from the example code on the wiki, I set a variable to the
'new Slider...' and then updated the handles property of that variable
after each click on a control.
var mySlider = new Control.Slider(rgb_slider.select('.handle'),
rgb_slider, {
range: $R(0, 255),
sliderValue: [45, 134, 189],
onSlide: function(values) {
box.setStyle({ backgroundColor: "rgb("+
values.map(Math.round).join(',') +")" });
},
onChange: function(values) {
box.setStyle({ backgroundColor: "rgb("+
values.map(Math.round).join(',') +")" });
}
});
$('add').observe('click',function(evt){
var h = new Element('div',
{'class':'handle'}).setStyle({backgroundColor:'#00f'});
rgb_slider.insert(h); mySlider.handles.push(h)
});
