How to detect linked smart objects in Photoshop?

Hi,

I need to detect smart objects linked to local files in specific locations from javascript in HTML5 extension. How can I do this?

Consider this pseudocode:

  if (app.documents.length)
  {
    var doc = app.activeDocument;
    for (var ilayer = 0; ilayer < doc.artLayers.length; ilayer++)
    {
      var layer = doc.artLayers[ilayer];
      if (LAYER_IS_LINKED_SMART_OBJECT(layer))
      {
        var localFilePath = GET_SMART_OBJECT_REFERENCED_FILEPATH(layer);
      }
    }
  }

Here I need implementations of two functions:

1. LAYER_IS_LINKED_SMART_OBJECT()

2. GET_SMART_OBJECT_REFERENCED_FILEPATH()

Thank you in advance!

Here's the final solution (without error checking):

  1.   if (app.documents.length)  
  2.   {  
  3.     var doc = app.activeDocument;  
  4.     for (var ilayer = 0; ilayer < doc.artLayers.length; ilayer++)  
  5.     {  
  6.       var layer = doc.artLayers[ilayer];  
  7.       if (layer.kind == LayerKind.SMARTOBJECT)  
  8.       {  
        var ref = new ActionReference();
        ref.putIdentifier(charIDToTypeID('Lyr '), layer.id );
    
        var desc = executeActionGet(ref);
        var smObj = desc.getObjectValue(stringIDToTypeID('smartObject'));
  1.         var localFilePath = smObj.getPath(stringIDToTypeID('link'));  
  2.       }  
  3.     }
  4.   }

    You are not detecting if the SO is linked SO: you just directly call the path of the linked file instead supposing the SO is linked - quite a difference, isn't it? So how can this be signed as solution is beyond me, sorry.

      I found how to check if the layer is a smart object:

      function LAYER_IS_LINKED_SMART_OBJECT(layer) {
        return layer.kind == LayerKind.SMARTOBJECT;
      }

      Still looking for the way to implement GET_SMART_OBJECT_REFERENCED_FILEPATH
