你可以这样做：

<script>
var x = document.getElementById("demo");
function getLocation() {
    if (navigator.geolocation) {
        navigator.geolocation.watchPosition(showPosition);
    } else {
        x.innerHTML = "Geolocation is not supported by this browser.";
    }
}
function showPosition(position) {
    x.innerHTML = "Latitude: " + position.coords.latitude +
    "<br>Longitude: " + position.coords.longitude;
}
</script>

或者您可以将最后的“if”替换为：

 Uri resourceAddress = new Uri("http://www.someurl.com/~?lalala");

 StorageFile img = await ApplicationData.Current.LocalFolder.GetFileAsync("ImageName.jpg");
 Stream inputStream = await img.OpenStreamForReadAsync();

 HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Post, resourceAddress);
 HttpMultipartContent cont = new HttpMultipartContent();
 cont.Add(new HttpStreamContent(inputStream.AsInputStream()));
 cont.Headers.ContentType = new HttpMediaTypeHeaderValue("image/jpeg");
 request.Content = cont;
 request.Headers.Connection.Add(new HttpConnectionOptionHeaderValue("Keep-Alive"));
 request.Content.Headers.ContentLength = (ulong)inputStream.Length;


 HttpResponseMessage response = await httpClient.SendRequestAsync(request);

 if (response.StatusCode == HttpStatusCode.Ok)
   {
      return true;
   }
