需要将文件路径数组转换为treeview json对象

var filePaths = [
  "root/folder1/file1.txt",
  "root/folder1/file2.txt",
  "root/folder2/",
  "root/folder2/file3.txt",
  "root/file4.txt"
];

var treeview = {};

for (var i = 0; i < filePaths.length; i++) {
  var filePath = filePaths[i];
  // 处理文件路径
}

var pathParts = filePath.split("/");

var currentNode = treeview; // 当前节点为treeview根节点

for (var j = 0; j < pathParts.length; j++) {
  var pathPart = pathParts[j];

  // 检查当前节点是否已存在该路径部分的子节点
  if (!currentNode[pathPart]) {
    // 如果不存在，创建一个新的子节点
    currentNode[pathPart] = {};
  }

  // 将当前节点更新为新创建的子节点
  currentNode = currentNode[pathPart];
}

{
  "root": {
    "folder1": {
      "file1.txt": {},
      "file2.txt": {}
    },
    "folder2": {
      "file3.txt": {}
    },
    "file4.txt": {}
  }
}
