从 typescript ionic 2+ 的不同方法获取数据

Question

tryGeolocation(){
this.loading.present();
this.clearMarkers();//remove previous markers

this.geolocation.getCurrentPosition().then((resp) => {
  let pos = {
    lat: resp.coords.latitude,
    lng: resp.coords.longitude
  };
  let marker = new google.maps.Marker({
    position: pos,
    map: this.map,
    title: 'I am here!'
  });
  this.markers.push(marker);
  this.map.setCenter(pos);
  this.loading.dismiss();

}).catch((error) => {
  console.log('Error getting location', error);
  this.loading.dismiss();
}); }

我想从地理定位中获取纬度和经度数据，并将该数据放入此方法。

openModal() {
const modal = this.modalCtrl.create('ModalPage');
modal.present(); }

怎么样？ #我是编程初学者

你必须像

一样通过

const modal = this.modalCtrl.create('ModalPage',{lat:72.33,lng:22.54});

下一页需要像下面这样

constructor(params: NavParams) 
{
    console.log('lat', params.get('lat'));
    console.log('lng', params.get('lng'));
}
