javascript解析树 [英] javascript parse tree

问题描述

我正在用jquery编写一个插件来成为文件管理器 我在php中建立文件夹结构，我使用ajax调用了该php文件，并且返回了类似的内容

i'm writing a plugin in jquery to be a file manager i build my folder structure in php i call that php file using ajax and i return something like this

{"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":[]}}

我如何使用jquery或javascript解析信息以执行类似的操作

how can i parse the info using jquery or javascript to do something like this

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

推荐答案

创建一个执行以下操作的函数: http://jsfiddle.net/k5BTr/.

Create a function which does that: 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);
