JSON遇到的问题

　　JSON.stringfy

　　JSON.parse

报错：unexpected token u in position 0

if (sessionStorage.getItem('houseIdList')) {
      this.formData.houseIds = JSON.parse(sessionStorage.getItem('houseIdList')).houseIds
    }

改为

if (sessionStorage.getItem('houseIdList')) {
      this.formData.houseIds = JSON.parse(JSON.stringify(sessionStorage.getItem('houseIdList'))).houseIds
    }
