【问题描述】：

如何获取纬度和经度值。 然后在没有地图的情况下在屏幕上显示值。

我使用代码：

function success(position) 
  var s = document.querySelector('#status');

  if (s.className == 'success') 
    // not sure why we're hitting this twice in FF, I think it's to do with a cached result coming back    
    return;
  

  s.innerhtml = "found you!";
  s.className = 'success';

  var mapcanvas = document.createElement('div');
  mapcanvas.id = 'mapcanvas';
  mapcanvas.style.height = '400px';
  mapcanvas.style.width = '560px';

  document.querySelector('article').appendChild(mapcanvas);

  var latlng = new google.maps.LatLng(position.coords.latitude, position.coords.longitude);
  var myOptions = 
    zoom: 15,
    center: latlng,
    mapTypeControl: false,
    navigationControlOptions: style: google.maps.NavigationControlStyle.SMALL,
    mapTypeId: google.maps.MapTypeId.ROADMAP
  ;
  var map = new google.maps.Map(document.getElementById("mapcanvas"), myOptions);

  var marker = new google.maps.Marker(
      position: latlng, 
      map: map, 
      title:"You are here! (at least within a "+position.coords.accuracy+" meter radius)"
  );


function error(msg) 
  var s = document.querySelector('#status');
  s.innerHTML = typeof msg == 'string' ? msg : "failed";
  s.className = 'fail';

  // console.log(arguments);


if (navigator.geolocation) 
  navigator.geolocation.getCurrentPosition(success, error);
 else 
  error('not supported');

“没有地图”是什么意思？您想从发布的代码中删除地图吗？

【参考方案1】：

使用你的成功方法的位置对象来获取纬度和经度值；

alert("Latitude: " + position.coords.latitude + 
    "<br>Longitude: " + position.coords.longitude)
