正在搜寻SO帖子，还没有任何答案。

我有一个像这样的文件夹数组：

[{
"name": "home",
"folders": [{
    "name": "New Folder",
    "folders": [{
        "name": "53w5r",
        "folders": [{
            "name": "test",
            "folders": []
        }]
    }]
}, {
    "name": "public folder",
    "folders": [{
        "name": "cold",
        "folders": []
    }, {
        "name": "hot",
        "folders": []
    }]
}, {
    "name": "My Folder",
    "folders": []
}]

}]

我需要使用如下路径字符串来搜索此数组：

"home,New Folder,53w5r,test"

我正在搜索该文件夹，因此findFolder方法将使用上面的字符串，并在“ test”文件夹中返回文件夹对象。

模样

假定用逗号分隔的路径始终有效，则可以使用以下简单方法遍历数据：

var str = "home,New Folder,53w5r,test";
var data = [{
  "name": "home",
  "folders": [{
    "name": "New Folder",
    "folders": [{
      "name": "53w5r",
      "folders": [{
        "name": "test",
        "folders": []
      }]
    }]
  }, {
    "name": "public folder",
    "folders": [{
      "name": "cold",
      "folders": []
    }, {
      "name": "hot",
      "folders": []
    }]
  }, {
    "name": "My Folder",
    "folders": []
  }]
}];

var folderNames = str.split(",");
var result = folderNames.reduce((results, folderName, index) => {
  var currFolder = results.find(folder => folder.name === folderName);
  // if last folder, return entire folder, otherwise return currFolder.folders
  return index === folderNames.length-1 ? currFolder : currFolder.folders;
}, data);
console.log(result);
