How to make a one-color fill images with masks in documents from our multiple layers ?

Hello everyone!

I`m to open PSD document with same layers. I need to:

1. Save the jpg file (preview) in a certain place

2. All layers with masks to make one-color fill instead of images with masks.

Thanks

This is way ?

var theLayers = collectLayers(app.activeDocument, []);
alert (theLayers.join("\n"));
function collectLayers (theParent, allLayers) {//---------------------------------------------------
if (!allLayers) {var allLayers = new Array}
   else {};
   for (var m = theParent.layers.length - 1; m >= 0;m--) {
      var theLayer = theParent.layers;
      if (theLayer.typename == "ArtLayer") {
           var bar = new Array;
           bar = theLayer.bounds
           l0= Math.abs(this.app.activeDocument.width - theLayer.bounds[2] - theLayer.bounds[0]);
           l1= Math.abs(this.app.activeDocument.height -theLayer.bounds[3] - theLayer.bounds[1]);
            if((l0+l1)>0) { // layer mask is set 
                // delete this layer
  
                //create new layer
  
                //create new mask from array bar
  
                //fill selection
  
            allLayers.push(theLayer);
            }
         }
     };
   return allLayers
   };
