  },
//=======================地图相关===================
getAddress(e) {
  var that = this;
  qqmapsdk.reverseGeocoder({
    success: function (res) {
      that.data.locObj.address = res.result.address
      that.setData({
        locObj: that.data.locObj
      })
      var res = res.result;
      var markerArr = [];
      var curLat=res.location.lat
      var curLng=res.location.lng
      // 36.66645
      // 117.07641
      markerArr.push({ 
        title: res.address,
        id: 0,

        latitude: (curLat+0.0009),
        longitude:(curLng+0.0003),
        iconPath: '/icon_map_addr_wc.png', 
        width: 28,

        latitude: (curLat-0.0009),
        longitude:(curLng+0.0011),
        iconPath: '/icon_map_addr_wc.png', 
        width: 28,
        height: 32,
      },{ 
        title: res.address,
        id: 4,
        latitude: (curLat+0.0004),
        longitude:(curLng+0.0011),
        iconPath: '/icon_map_addr_house.png', 
        width: 28,

      },{ 
        title: res.address,
        id: 5,

        iconPath: '/icon_map_addr_hospital.png', 
        width: 28,
        height: 32,
      });
      that.data.locObj.latitude = res.location.lat
      that.data.locObj.longitude = res.location.lng
      that.setData({ // 设置markers属性和地图位置poi，将结果在地图展示
        markers: markerArr,
        locObj: that.data.locObj
      });
    },
    fail: function (error) {
      console.error(error);
    },
    complete: function (res) {
