同様のGPSの問題をいくつか確認しました。しかし、あまり運がなかったようです。この方法でGPSをプルすると、古いデータ、つまり最後のGPSプルがどこから来たのかをプルしているように見えます。助言がありますか?
これは単純なJavaScriptGPSプルであり、要求されたときにフォームに入力されます。
<script type="text/javascript">
function getLocationConstant()
{
if(navigator.geolocation)
{
watchID = navigator.geolocation.watchPosition(onGeoSuccess,onGeoError);
} else {
alert("Your browser or device doesn't support Geolocation");
}
}
// Get a single location update
function getLocationConstant()
{
if(navigator.geolocation)
{
navigator.geolocation.getCurrentPosition(onGeoSuccess,onGeoError);
} else {
alert("Your browser or device doesn't support Geolocation");
}
}
// If we have a successful location update
function onGeoSuccess(event)
{
document.getElementById("Latitude").value = event.coords.latitude;
document.getElementById("Longitude").value = event.coords.longitude;
}
// If something has gone wrong with the geolocation request
function onGeoError(event)
{
alert("Error code " + event.code + ". " + event.message);
}
</script>
