Question

我确定之前应该由Photoshop脚本编写者讨论过。我写了一个解决方案如下。我认为它在逻辑上是对的，但结果并不正确。任何人都可以帮助检查代码中的错误，或者对此主题有什么想法？我想获取文档中的所有图层。

代码：

function getAllLayersInLayerSets(layerNodes) {

 var retList = [];

 for (var i=0; i<layerNodes.length; i++) {

    if(layerNodes[i].layerSets.length > 0)
    {
        var tmp = getAllLayersInLayerSets(layerNodes[i].layerSets);

        var j = (tmp == null) ? -1 : tmp.length-1;
        while(tmp && j>=0)
        {
            retList.push(tmp[i]);
            j--;
        }
    }
    for(var layerIndex=0; layerIndex < layerNodes[i].artLayers.length; layerIndex++) 
    {
        var layer=layerNodes[i].artLayers[layerIndex];
        retList.push(layer);
    }

}

return retList;  
}

非常感谢任何帮助或讨论。

我知道这是一个旧线程，但这可能对某人有用。

我正在寻找能够让我在Photoshop中获得所有ArtLayers的功能，包括嵌套在群组中的图层。上面的函数返回undefined，所以我修改了它并让它工作。

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;
}

要获得所有图层（和子图层），您必须具有递归函数

var allLayers = new Array();
var theLayers = collectAllLayers(app.activeDocument, 0);


function collectAllLayers (theParent, level)
{
  for (var m = theParent.layers.length - 1; m >= 0; m--)
  {
    var theLayer = theParent.layers[m];
    if (theLayer.typename != "ArtLayer")
    {
      allLayers.push(level + theLayer.name);
      collectAllLayers(theLayer, level + 1)
    }
  }
}

Ghoul Fool的帖子略有扩展，只能获得活动文档中的所有可见艺术图层。：P

// Get layers in a document
var sourceDocument = app.activeDocument;
var visibleLayers  = [];
var visibleLayers  = collectAllLayers(sourceDocument, visibleLayers);

// Print out total layers found
alert(visibleLayers.length);


// Recursively get all visible art layers in a given document
function collectAllLayers (parent, allLayers)
{
    for (var m = 0; m < parent.layers.length; m++)
    {
        var currentLayer = parent.layers[m];
        if (currentLayer.typename === "ArtLayer")
        {
            if(currentLayer.visible)
            {
                allLayers.push(currentLayer);
            }
        }
        else
        {
            collectAllLayers(currentLayer, allLayers);
        }
    }
    return allLayers;
}

function selectAllLayers() {
    var desc29 = new ActionDescriptor();
    var ref23 = new ActionReference();
    ref23.putEnumerated(charIDToTypeID('Lyr '), charIDToTypeID('Ordn'), charIDToTypeID('Trgt'));
    desc29.putReference(charIDToTypeID('null'), ref23);
    executeAction(stringIDToTypeID('selectAllLayers'), desc29, DialogModes.NO);
}
