将具有"path“属性的平面数组转换为嵌套数组

function flattenToNestedArray(flatArray) {
  let nestedArray = [];
  let pathMap = {};

  // 构建嵌套数组对象
  for (let element of flatArray) {
    let pathSegments = element.path.split("/");
    let currentObject = null;

    for (let i = 0; i < pathSegments.length; i++) {
      let pathSegment = pathSegments[i];
      let currentPath = pathSegments.slice(0, i + 1).join("/");

      if (!pathMap[currentPath]) {
        let nestedObject = { name: pathSegment, children: [] };
        pathMap[currentPath] = nestedObject;

        if (i === 0) {
          nestedArray.push(nestedObject);
        } else {
          let parentPath = pathSegments.slice(0, i).join("/");
          let parentObject = pathMap[parentPath];
          parentObject.children.push(nestedObject);
        }
      }

      currentObject = pathMap[currentPath];
    }

    // 添加当前元素的剩余属性
    for (let key in element) {
      if (key !== "path") {
        currentObject[key] = element[key];
      }
    }
  }

  return nestedArray;
}

// 示例用法
let flatArray = [
  { "name": "文件1", "path": "文件1" },
  { "name": "文件2", "path": "文件2" },
  { "name": "文件夹1", "path": "文件夹1" },
  { "name": "文件夹1/文件1", "path": "文件夹1/文件1" },
  { "name": "文件夹1/文件2", "path": "文件夹1/文件2" },
  { "name": "文件夹2", "path": "文件夹2" },
  { "name": "文件夹2/文件1", "path": "文件夹2/文件1" },
  { "name": "文件夹2/文件2", "path": "文件夹2/文件2" }
];

let nestedArray = flattenToNestedArray(flatArray);
console.log(nestedArray);
