map如何转化为json

如何将map数据转换为json数据，map数据格式如下（{fID=TiK7cXajpgbi3SYqibP, parent=3, hasChild=nkLeaf, safetyMeasuresTemplate=景泰风电场}）

这个就是java的标准操作，可以到网上查找

可以将JSON = {"fID":"3avSLdUTZJpmIWmGuro","hasChild":"nkLeaf","parent":"3","safetyMeasuresTemplate":"南湫风电场"}直接放在
  var options = {
// "parsent":"$UI2/IOMM/common/process/common/safetyMeasures/staticData/Row==3",
defaultValues : [
JSON
   ]
这样写为什么报错呀？页面中也没有写userdata呀,请问这是什么原因？
Cannot read property 'userdata' of undefined

完整的代码发一下
data的定义发一下

前台调用action，也没有问题，可以拿到action返回的值
Model.prototype.sa_oporgTable = function(event) {// 查询所有风场
biz.Request.sendBizRequest({
"context" : this.getContext(),
"action" : "querySA_Oporg",
// "parameters" : params,
"callback" : function(data) {
if (data.state) {
var sa_oporgTable = data.response;
var s = sa_oporgTable.toString();
alert(data.response);// js获取后台java代码返回的值（data.response获取）
return s;
} } }); }

这一块会报上述错误，主要代码已经上传，不知道是为什么？？请问这是什么原因？？？
staticData是cdata,前台添加的静态数据

var json = this.sa_oporgTable();//
      if (code !== null && code !== "") {
                     var Name = context.getCurrentOgnFName();
                     alert(Name);
                     var options = {
                              defaultValues : [
                                       json//这块就会报错，不知道是为什么
                              ],
                              parent : staticData.getRowByID("3")
                     };
                     staticData.newData(options);

data的定义发一下

lmk123 · 发表于 2016-12-22 17:09:30

data 只是页面展示，没有在数据库中，使用的是静态数据，具体如图所示

发源码我本地测试一下
