循环到对象中的文件系统结构以获取所有文件 [英] Loop to a filesystem structure in my object to get all the files

问题描述

我从服务器上获得了一个Javascript对象，该对象描述了一个文件系统.现在我想获取系统中所有文件的路径，例如树的端点.

I get a Javascript Object from my server, which depicts a filesystem. Now I want to get the path of all files in the system, e.g. the endpoints of the tree.

文件结构示例:

└── pages
    └── services
        └── project            
            │── headline
            │── test
            │   └── text
            │   └── picture 
            │── text

可读JSON:

{
"path":"/pages/services/project",
"is_dir":true,
"children":[
  {
     "path":"/pages/services/project/headline",
     "is_dir":false,
     "children":[

     ]
  },
  {
     "path":"/pages/services/project/text",
     "is_dir":false,
     "children":[

     ]
  },
  {
     "path":"/pages/services/project/test/",
     "is_dir":true,
     "children":[
        {
           "path":"/pages/services/project/test/text",
           "is_dir":false,
           "children":[

           ]
        },
        {
           "path":"/pages/services/project/test/picture",
           "is_dir":false,
           "children":[

           ]
        }
     ]
  }

]}

预期输出:

/pages/services/project/headline
/pages/services/project/text
/pages/services/project/test/text
/pages/services/project/test/picture

我稍微递归地玩了一下，做了一个愚蠢的功能，当一个dir只有一个孩子时，该功能可以工作.我的问题是我无法掌握处理更多孩子的方法.有没有办法遍历每个孩子?

I played around a little bit with recursion and made a dumb function that works when a dir has only one child. My Problem is that I can`t grasp a way to handle more children. Is there a way to iterate over every child?

这是我的代码:

var json = {"path":"/pages/services/project", "is_dir":true, "children":[{"path":"/pages/services/project/headline","is_dir":false,"children":[]},{"path":"/pages/services/project/text","is_dir":false,"children":[]},
{"path":"/pages/services/project/test/","is_dir":true,"children":[{"path":"/pages/services/project/test/text","is_dir":false,"children":[]},
{"path":"/pages/services/project/test/picture","is_dir":false,"children":[]}]}]};

json.children.forEach(function (child) {
	out(goToDeepestPoint(child).path);
});



function goToDeepestPoint(node) {
    if (node.is_dir)
        return goToDeepestPoint(node.children[0]);
    else 
        return node;
}

function out()
{
    var args = Array.prototype.slice.call(arguments, 0);
    document.getElementById('output').innerHTML += args.join(" ") + "\n";
}

<pre id="output"></pre>

推荐答案

我正忙于解决您的原始问题，并使其正常工作:

I was busy having a play with your original question and got this working:

goToDeepestPoint(json);

function goToDeepestPoint(node) {
    if (node.is_dir)
        node.children.forEach(function (child) {
    goToDeepestPoint(child);
});
    else 
        return out(node.path);
}

根据您的编辑可能不适当，但浪费它可耻！

May not be appropriate in the light of your edit, but shame to waste it!
