vue-cli的项目hbuilder打包后 还是调不到h5 plus的方法啊  这个怎么解决

mounted(){
    this.plusReady(function() {
      // 获取定位信息
      var self = this;
      this.$geolocation.getCurrentPosition().then(function (position) {
        self.city = position.address.city;
      });
      // 获取网络信息
      self.networkType = this.$networkinfo.getCurrentNetworkType();
    })
    }
