this didn't work ... the ImageMapType isn't a MVCObject. So instead I
made a new ImageMapType when there's a change in opacity. SQLArray
now ensures the MVCArray is up to date by listening to changes in the
"select" and "where" attributes of its MVCObjects.
Using jQuery sliders:
$("#slider_" + layers[i].id).slider({
min: 0,
max: 1,
step: 0.1,
value: 1,
change: sliderHandler(layers[i].id)
});
function sliderHandler(id) {
return function(event, ui) {
overlays.get(id).set("mapType", createImageMapType(id, ui.value));
};
}
