javascript - 通过 jQuery 将 JSON 对象转换为格式化数组

Question

我有一个 JSON 对象，我想将其转换为数组，以便我可以将它与 bootstrap-treeview 一起使用。 jQuery 插件。为此，我需要 JSON 对象采用以下格式:

var tree = [
{
  text: "Parent 1",
  nodes: [
    {
      text: "Child 1",
      nodes: [
        {
          text: "Grandchild 1"
        },
        {
          text: "Grandchild 2"
        }
      ]
    },
  {
    text: "Child 2"
  }
]
},
{
  text: "Parent 2"
},
{
  text: "Parent 3"
},
{
  text: "Parent 4"
},
{
  text: "Parent 5"
}
];

我知道我可能需要递归地迭代 JSON 对象，但我不知道如何进行。

希望这有帮助!

    arrConvert = new Array();
    function convertItem(p){
        arrItem = new Array();
        for (var key in p) {
              if (p.hasOwnProperty(key)) {
                  if($.type(p[key]) === "string" || $.type(p[key]) === "number" )
                      arrItem.push({"text":p[key]});
                  else{
                      arrItem.push({"nodes":convertItem(p[key])});
                  }
              }
        }
        return arrItem;
    }

    $(function(){
        var testArr = {
                        "SectionsData":[
                                    {"Characteristics":"abc", "Entropy":1.55288}, 
                                    {"Characteristics":"xyz",   "Entropy":1.55288},
                                    {"Characteristics":"mno", "Entropy":1.55288}
                                ],
                        "NumberOfSections":29,
                        "SHA1":"7ED11BBA8EF27B8‌​FE8617F5446142A3A0613CC41",
                        "Entropy":6.06652,
                        "CodeSection":[
                                        {"Characteristics":"abc1", "Entropy":1.55288}, 
                                        {"Characteristics":"xyz2",  "Entropy":1.55288},
                                        {"Characteristics":"mno3", "Entropy":1.55288}
                                    ]        
                        };

        //This is array after convert
        arrConvert = convertItem(testArr);
    });
