js：

onLoad: function () {

// 获取位置

var that = this;

// 实例化腾讯地图API核心类

qqmapsdk = new QQMapWX({

});

wx.getLocation({

type: 'wgs84',

success: function (res) {

that.setData({

latitude:res.latitude,

longitude:res.longitude

//2、根据坐标获取当前位置名称，显示在顶部:腾讯地图逆地址解析

qqmapsdk.reverseGeocoder({

（为什么这一段不会打印）

that.setData({

location: location

})

}

// console.log("res==" + app.globalData.longitude)

that.setData({
