currentTarget不能有大写
改为currenttarget

onShow: function (e) {
    let that = this;
    util.request(api.GetCountryList).then(function (res) {



      that.setData({
        
        Country_List: res.CountryList
      });


      var cityNameTemp = e.currenttarget.dataset.name
      //这是(if)作为区别查询按钮和country和province区别 
      console.log(cityNameTemp)


      


     

      });
      }
