js 将一个数组中的部分字段，添加到另外一个数组中

原来的data数组

截取部分字段

  var area = []
          data.forEach((item) => {
            area.push({ areaCode: item.id, areaName: item.name })
          })

结果

{“area”:[{“areaCode”:“340129”,“areaName”:“高新区”},{“areaCode”:“340128”,“areaName”:“经开区”},{“areaCode”:“340127”,“areaName”:“滨湖新区”},{“areaCode”:“340126”,“areaName”:“新站区”},{“areaCode”:“340125”,“areaName”:“巢湖市”},{“areaCode”:“340124”,“areaName”:“庐江县”},{“areaCode”:“340123”,“areaName”:“肥西县”},{“areaCode”:“340122”,“areaName”:“肥东县”},{“areaCode”:“340121”,“areaName”:“长丰县”},{“areaCode”:“340111”,“areaName”:“包河区”},{“areaCode”:“340103”,“areaName”:“庐阳区”},{“areaCode”:“340104”,“areaName”:“蜀山区”},{“areaCode”:“340102”,“areaName”:“瑶海区”}]}
