往对象里面塞对象的问题

Question

后台给了我一个json数据格式让我传过去，对象里面还有对象，要怎么写相关代码// 请把代码文本粘贴到下方（请勿用图片代替代码）json格式：      {        "cityid":"100003530",        "region":             {             "region":"123"            },        "cityname":"nihao"       }如果是单纯的     {        "cityid":"100003530",        "region": "123",        "cityname":"nihao"       }      var obj={};       obj.cityid='100003530';       obj.region='123';       obj.cityname='nihao';我可以 请教下像第一种要怎么写？

Answer 1

没看懂问题想表达的是什么

let obj = {        "cityid":"100003530",        "region": 
           {             "region":"123"
           },        "cityname":"nihao"
      }
      obj.cityid = "100003530"
      obj.region = {             "region":"123"
           }
      obj.region = {}
      obj.region.region = "123"
      obj.cityname = "nihao"

Answer 2

      var obj={};
      obj.cityid='100003530';
      obj.region={region: '123'};
      obj.cityname='nihao';
