indesign script: remove/hide all empty graphic frames placed in a specific layer

Question

I have a multipage indesign document and in it several layers; one layer is called obrazy and in this layer on every page some frames are placed (the frames are also styled with an object style called obraz), then some of the frames are filled with images and some remain empty; what I need is a script (in javascript) to go through the document end move the empty frames into a different layer (can be new or already existing) which will later be hidden. The script must only manipulate frames in a specific layer or with a specific object style since there are other frames in the other layers. I have written several versions (and spent hours of experimenting and going through various sources and similar scripts) but still do not have a fully working solution. I guess I am missing some details... Any pointers or suggestions would be very helpful. Thanks.

ok, here is what is now working for me:

var dok = app.activeDocument;
var pocetstran = dok.pages.length;
var vrstvaobrazu = dok.layers.item("obrazy");

for (var j = 0; j<pocetstran; j++) {
    for (var i = 0; i < dok.layers.item("obrazy").rectangles.length; i++) {
        if ((dok.layers.item("obrazy").rectangles.item(i).images.length == 0)){
        dok.layers.item("obrazy").rectangles.item(i).remove();
        }
    }
}
