js中如何把json数组转成json对象


JSONArray jsonarray = JSONArray.fromObject(comList); 
//List<String> strList = new ArrayList<String>();
pWriter.print(jsonarray);
ajax到后台获得的json数组var json = 
[
    {
          "cId":"0011",
          "cName":"aaa",
          "list":[
                 {"dId":"0001","dName":"监查审计部","deptList":[]},
                 {"dId":"Dpt0002","dName":"财务部","deptList":[]
                 ]
     },
    {
          "cId":"0001",
          "cName":"bbb",
          "list":[
                 ]
     }
]
想把他转成json对象，一定要是json对象
var newJson = {
                 id:"0011",
                 name:"aaa",
                 children:[
                            {
                              id:"0001",
                              name:"监查审计部",
                              children:[]
                             },
                            {
                               id:"Dpt0002",
                               name:"财务部",
                               children:[]
                             }
                           ] 
             },
            {
                id:"0001",
                name:"bbb",
                children:[] 
             }
就是json数组 转换成json对象，必须是
