JavaScript 解析树

Question

我正在用 jquery 编写一个插件作为文件管理器 我在 php 中构建我的文件夹结构，我使用 ajax 调用该 php 文件，然后返回类似这样的内容

{"1":[],"css":{"admin":[],"tabs":{"skin1":{"images":[]},"skin10":{"图像":[]},"skin11":{"图像":[]},"skin12":{"图像":[]},"skin2":[],"skin3":{"图像":[ ]},"skin4":{"图像":[]},"skin5":{"图像":[]},"skin6":{"图像":[]},"skin7":{"图像":[]},"skin8":{"图片":[]},"skin9":{"图片":[]}}},"img":{"admin":[],"filemanager":[ ],"图标":[]},"js":{"libs":[]},"菜单":{"img":[]},"walpappere":{"1":[]}}

如何使用 jquery 或 javascript 解析信息来执行类似的操作

var mystring = ''

foreach key (would be 1,css etc)

  mystring += key

  if has children

     mystring += key

     for each children same as above until all structure is parsed

创建一个执行此操作的函数:http://jsfiddle.net/k5BTr/ .

var obj = {"1":[],"css":{"admin":[],"tabs":{"skin1":{"images":[]},"skin10":{"images":[]},"skin11":{"images":[]},"skin12":{"images":[]},"skin2":[],"skin3":{"images":[]},"skin4":{"images":[]},"skin5":{"images":[]},"skin6":{"images":[]},"skin7":{"images":[]},"skin8":{"images":[]},"skin9":{"images":[]}}},"img":{"admin":[],"filemanager":[],"icons":[]},"js":{"libs":[]},"menu":{"img":[]},"walpappere":{"1":[]}};

function list(items, level) {
    for (var key in items) { // iterate
        if (items.hasOwnProperty(key)) {
            // write amount of spaces according to level
            // and write name and newline
            document.write(
                (new Array(level + 1)).join(" ") +
                key +
                "<br>"
            );

            // if object, call recursively
            if (items[key] != null && typeof items[key] === "object") {
                list(items[key], level + 1);
            }
        }
    }
}

list(obj, 0);
