Question

我正在创建一个AppleScript，我需要在Photoshop上对所选图层执行某些操作。

即使所选图层位于组内，如何获取Photoshop上所选图层的列表？

我现在没有要显示的代码，因为这一切都始于拥有所选图层的列表，抱歉。

所选图层不是JavaScript的artLayer对象中的属性，并且选中它也不是AppleScript中layer对象的属性。但是我们可以在PhotoShop中使用AM并使用动作和描述符结果来获取所选图层。因为层可能需要根据是否存在背景层而快速移动，所以我们首先创建一个包含选定索引的数组（代码基于this post），然后我们解析层的名称。

tell application "Adobe Photoshop CS6"
    tell document 1
        set selectedLayers to paragraphs of (do javascript "
var typeDocument        = stringIDToTypeID('document');
var typeItemIndex       = stringIDToTypeID('itemIndex');
var typeLayer           = stringIDToTypeID('layer');
var typeName            = stringIDToTypeID('name');
var typeOrdinal         = stringIDToTypeID('ordinal');
var typeProperty        = stringIDToTypeID('property');
var typeTarget          = stringIDToTypeID('targetEnum');
var typeTargetLayers    = stringIDToTypeID('targetLayers');
var selectedLayers  = new Array();
var actionRef           = new ActionReference();

actionRef.putEnumerated(typeDocument, typeOrdinal, typeTarget);
var actionDesc = executeActionGet(actionRef);

if(actionDesc.hasKey(typeTargetLayers) ){
    actionDesc = actionDesc.getList(typeTargetLayers);
    var c = actionDesc.count

    for(var i=0;i<c;i++){
        try{
            activeDocument.backgroundLayer;
            selectedLayers.push(actionDesc.getReference( i ).getIndex() );
        }catch(e){
            selectedLayers.push(actionDesc.getReference( i ).getIndex()+1 );
        }
    }
}else{
    var actionRef = new ActionReference();
    actionRef.putProperty(typeProperty , typeItemIndex);
    actionRef.putEnumerated(typeLayer, typeOrdinal, typeTarget);
    try{
        activeDocument.backgroundLayer;
        selectedLayers.push( executeActionGet(actionRef).getInteger(typeItemIndex)-1);
    }catch(e){
        selectedLayers.push( executeActionGet(actionRef).getInteger(typeItemIndex));
    }
}

var selectedLayerNames = new Array();

for (var a in selectedLayers){
    var ref = new ActionReference();   
    ref.putIndex(typeLayer, Number(selectedLayers[a]) );  
    var layerName = executeActionGet(ref).getString(typeName);
        selectedLayerNames.push(layerName);  
}

selectedLayerNames.join('\\n');
")

    end tell
end tell
