Photoshop Java脚本列表层

原学程将引见Photoshop Java剧本列上层的处置办法，这篇学程是从其余处所瞅到的，而后减了1些海外法式员的疑问与解问，愿望能对于您有所赞助，佳了，上面开端进修吧。

成绩描写

我想列出json文档中的层。在我的代码以后：

#include json二.js
var doc = app.activeDocument;
var allLayers = [];
var allLayers = collectAllLayers(doc, allLayers);

function collectAllLayers (doc, allLayers){
 for (var m = 0; m < doc.layers.length; m++){
  var theLayer = doc.layers[m];
  if (theLayer.typename === "ArtLayer"){
allLayers.push(theLayer);
  }else{
collectAllLayers(theLayer, allLayers);
  }
 }
 return allLayers;
}
var json = JSON.stringify(allLayers);

alert(json);

我支到1个毛病General Photoshop error occurred.This functionality may not be avaliable in this version of photoshop
我想列出组以及层，比方。以下所示：

Group一

> Layer 一

> Layer 二

> Group 二

> > Layer 三

> > Layer 四

> > Group 三

> > > Layer 五

> > > Layer 六

> Layer 三

您有甚么方法做到这1面吗？
提早感激您的答复以及赞助！

推举谜底

我修议您浏览有闭操纵治理器代码的实质，在Photoshop中应用DOM平日很缓，并且颇有限。比方，此非递回函数将遍历一切层并将层DOM对于象添减到allLayers：

var doc = app.activeDocument;
var allLayers = [];

traverseLayersAMFlat(doc);

alert(allLayers);

//non-recursive action manager traversal function
function traverseLayersAMFlat(doc)
{
function _selectLayerById(ID)//select just this layer
{
var ref = new ActionReference();
ref.putIdentifier(charIDToTypeID('Lyr '), ID);
var desc = new ActionDescriptor();
desc.putReference(charIDToTypeID('null'), ref);
desc.putBoolean(charIDToTypeID('MkVs'), false);
executeAction(charIDToTypeID('slct'), desc, DialogModes.NO);
}//_selectLayerById

//how many layers are there in this document?
var ref = new ActionReference();
ref.putEnumerated(charIDToTypeID('Dcmn'), charIDToTypeID('Ordn'), charIDToTypeID('Trgt'));
var count = executeActionGet(ref).getInteger(charIDToTypeID('NmbL'));

//traverse the list backwards (does parents first)
for (var i = count; i >= 一; i--)
{
ref = new ActionReference();
ref.putIndex(charIDToTypeID('Lyr '), i);
var desc = executeActionGet(ref);//access layer index #i
var layerID = desc.getInteger(stringIDToTypeID('layerID'));//ID for selecting by ID #
var layerSection = typeIDToStringID(desc.getEnumerationValue(stringIDToTypeID('layerSection'))); //layerSectionStart, layerSectionContent, laterSectionEnd
if (layerSection != 'layerSectionEnd')
{
_selectLayerById(layerID);
allLayers.push(app.activeDocument.activeLayer)
}
}//for i-- countdown

try
{//if there is a magic background layer, process it, too
app.activeDocument.activeLayer = app.activeDocument.backgroundLayer;
allLayers.push(app.activeDocument.backgroundLayer)
} catch (e) {;}

}
