javascript使用百度地图api和html5特性获取浏览器位置

复制代码 代码如下:
<!DOCTYPE html>
<html>
<body>
<p id="demo">点击这个按钮，获得您的位置：</p>
<button onclick="getLocation()">试一下</button>
<script src="/UploadFiles/2021-04-02/api?v=1.4"><script>
var x=document.getElementById("demo");
function getLocation(){
    if(navigator.geolocation){
       navigator.geolocation.getCurrentPosition(showPosition);
      }else{
       alert("您的浏览器不支持地理定位");
      }
   }

function showPosition(position){
    lat=position.coords.latitude;
    lon=position.coords.longitude;
    //var map = new BMap.Map("container");            // 创建Map实例
    var point = new BMap.Point(lon, lat);    // 创建点坐标
    //map.centerAndZoom(point,15);                     //
    //map.enableScrollWheelZoom();
    var gc = new BMap.Geocoder();   
    gc.getLocation(point, function(rs){
       var addComp = rs.addressComponents;
       alert(addComp.province + ", " + addComp.city + ", " + addComp.district + ", " + addComp.street);
      });
   }
</script>
</body>
</html>
