关于 javascript：使用 Photoshop 脚本更改选定的文本图层语言

Changing selected text layers language with photoshop script

虽然我设法将一个功能性脚本一起更改所选图层的字典语言，但这还不是我所需要的。

我目前正在检索我选择的图层的索引，使用它们来获取图层名称——这是有问题的部分——然后根据我显示的自定义对话框中选择的选项使用魔法来更改它们的语言。

图层名称的使用是一个非常不成熟的解决方案，我需要精确，我需要能够根据图层 ID 或索引更改语言。不仅我的脚本容易出现名称冲突，而且我不知道这些选定的图层将在哪里，如果在文档的根目录上或在 5 个组堆栈内。

这是我当前的代码：

(createWindow 返回一个 lang 值，跳过它)

function setLangByIndex(idx, lang){
ref = new ActionReference();
ref.putProperty( charIDToTypeID("Prpr") , charIDToTypeID("Nm " ));
ref.putIndex( charIDToTypeID("Lyr" ), idx );
var name = executeActionGet(ref).getString(charIDToTypeID("Nm " ));

var el = activeDocument.layers.getByName( name );
// Temp quick block; MUST UPDATE IN CASE OF NEW LANGUAGES
if (lang == 'pt_br' )
el.textItem.language = Language.BRAZILLIANPORTUGUESE;
else if (lang == 'en_us' )
el.textItem.language = Language.ENGLISHUSA;
else
el.textItem.language = Language.ENGLISHUK;
}

我尝试低效的解决方法：

使用 Adob??e 的脚本侦听器通过 executeAction 更改语言，
但无法使其工作。语言部分在?4堆叠内
描述符(和一个列表！)。我迷路了，不断收到错误 8800。
弄清楚如何使用 idx 获取对象 ref。失败的
悲惨地。

相关讨论

在我注意到与段落样式相关的一些烦人的故障(您可以将其定义为 PS 上文本的默认设置，而不是 JS 对象)之后，我放弃了固执并停止避免通过索引数组执行新循环完成后重新选择图层。
