Load selection of all masks inside a group

Hi!

 

I am having a hard time trying to load the selection of all the layer masks inside a group. The group can contain different numbers of layers that contain layer masks (names of the layers will be different, but the group name is always the same) . I would like to have a selection of all layer masks, like clicking on the mask with cmd+shift.

 

I don’t quite understand how loops work, and I am struggling to make it work.

    It works, even though I get a message specifying the layer name and index. In line 118, I can modify what is shown in the message, but I don't know a way to avoid it altogether.


    Sorry, must have forgotten that; just delete the line 

    alert (theGroup.join("\n"));

    altogether.

    Why do you need this selection? In general, it is useless

      We have some layers of effects that we only want to affect the visible part of the layers inside the group. We can clip them to the group, but to reduce the file size, we delete the parts of the image that are not in use (the black parts of the mask). 

      It probably doesn't make sense to you, but it is useful to us.

      What is the problem exactly? 

      Please provide a sample file.

      I think I missed the word script in my message. I am looking for a way to automate loading selections of all the masks of the layers within a group. I attached a small psd file with a group with two layers, hope I made it easier to understand now.
