从目录路径中以字符串形式获取对象数组中的目录路径 [英] Get directory path in Array of Objects from directory path as string

问题描述

曾经搜索过这样的帖子，但现在还没有任何答案.

Been searching SO posts, nothing answers this for me yet.

我有一个类似这样的文件夹数组:

I have an Array of folders like such :

[{
"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:

I need to find search this array using a path string such as the following :

"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.

I'm searching for that folder, so a findFolder method would take the string above and return the folder objects in the "test" folder .

推荐答案

假定您的逗号分隔路径始终有效，则可以使用以下简单方法遍历数据:

Assuming that your comma-separated path will always be valid, you can use this simple method for traversing the data:

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);
