从extendscript中的路径递归填充树视图

Question

我正在研究Adobe After Effects的extendcript函数，它需要能够将下面的文件路径列表转换为树视图。到目前为止，这是我的代码，它遍历了第一个＆＃34;级别＆＃34;很好，但我遇到了递归问题。我非常感谢帮助，我对这个问题的打击并不能让它开始工作！

我通过删除递归来简化你的代码。因为你没有走层次，所以不需要它;每条路径都有层次结构。

结果如下：

{
   //----| Build UI
   var stImporterWin = new Window("palette", "ST Import Panel", undefined, {resizeable:true});
   stImporterWin.orientation = "column";

   var imageSequenceGroup = stImporterWin.add("group");
   imageSequenceGroup.alignment = ["fill", "fill"];
   imageSequenceGroup.orientation = "column";
   var imageSequenceTree = imageSequenceGroup.add("treeview");
   imageSequenceTree.preferredSize = [600,650];
   imageSequenceTree.alignment = ["fill", "fill"];


   stImporterWin.onResize = function () {
      this.layout.resize();
   }

   stImporterWin.show();
