Question

我获得了Google Places API代码，并且我还添加了代码，我已经有了像纬度和经度这样的当前位置，但我不知道如何将变量如lat1和lng1传递给Google API。

    <script type="text/javascript">
     function initGeolocation()
     {
        if( navigator.geolocation )
        {
           navigator.geolocation.getCurrentPosition( success, fail );
        }
        else
        {
           alert("Sorry, your browser does not support geolocation services.");
        }
     }

     function success(position)
     {

         var lng1= position.coords.longitude;
         var lat1= position.coords.latitude;
     }


      function fail()
      {
        // Could not obtain location
      }

    </script>  
    <script>


      var map;

      var infowindow;

      function initMap() {
        var pyrmont = {lat:lat1, lng:lng1};

        map = new google.maps.Map(document.getElementById('map'), {
          center: pyrmont,
          zoom: 15
        });

        infowindow = new google.maps.InfoWindow();
        var service = new google.maps.places.PlacesService(map);
        service.nearbySearch({
          location: pyrmont,
          radius: 500,
          type: ['store']
        }, callback);
      }

      function callback(results, status) {
        if (status === google.maps.places.PlacesServiceStatus.OK) {
          for (var i = 0; i < results.length; i++) {
            createMarker(results[i]);
          }
        }
      }

      function createMarker(place) {
        var placeLoc = place.geometry.location;
        var marker = new google.maps.Marker({
          map: map,
          position: place.geometry.location
        });

        google.maps.event.addListener(marker, 'click', function() {
          infowindow.setContent(place.name);
          infowindow.open(map, this);
        });
      }

    </script>

我已经声明了变量但是当我通过它时什么也没有显示...... 提前谢谢！如果有人知道如何将当前纬度和经度变量传递给谷歌API代码，请在此处留下答案！

 <p>Click the button to get your coordinates.</p>

  <button onclick="getLocation()">Try It</button>

  <p id="demo"></p>



<script>
 var x = document.getElementById("demo");

   function getLocation() {
if (navigator.geolocation) {
    navigator.geolocation.getCurrentPosition(showPosition, showError);
} else { 
    x.innerHTML = "Geolocation is not supported by this browser.";
 }
}

    function showPosition(position) {
x.innerHTML = "Latitude: " + position.coords.latitude + 
"<br>Longitude: " + position.coords.longitude;
 }

   function showError(error) {
switch(error.code) {
    case error.PERMISSION_DENIED:
        x.innerHTML = "User denied the request for Geolocation."
        break;
    case error.POSITION_UNAVAILABLE:
        x.innerHTML = "Location information is unavailable."
        break;
    case error.TIMEOUT:
        x.innerHTML = "The request to get user location timed out."
        break;
    case error.UNKNOWN_ERROR:
        x.innerHTML = "An unknown error occurred."
        break;
  }
 }
</script>
