ขอปรึกษาการใช้ HTML5 เพื่อดึงข้อมูล Geolocation บน web server แต่ละแบบ
geolocation มันเป็น js รันบนเบราเซอร์ ไม่ว่าจะวางไว้ที่ไหนมันก็รันได้เหมือนกันไม่เกี่ยวกับ web server

Code (JavaScript)
<!DOCTYPE html>
<html>
<body>
<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);
} 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>
</body>

ตอนนี้ หาวิธีแก้ปัญหานี้ได้แล้วนะครับCode (PHP) <!DOCTYPE html>
<html>
<head>
<title>GEOIP DB - jQuery example</title>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
</head>
<body>
<div>Country: <span id="country"></span>
<div>State: <span id="state"></span>
<div>City: <span id="city"></span>
<div>Latitude: <span id="latitude"></span>
<div>Longitude: <span id="longitude"></span>
<div>IP: <span id="ip"></span>
<script>
$.ajax({
url: "https://geoip-db.com/jsonp",
jsonpCallback: "callback",
dataType: "jsonp",
success: function( location ) {
$('#country').html(location.country_name);
$('#state').html(location.state);
$('#city').html(location.city);
$('#latitude').html(location.latitude);
$('#longitude').html(location.longitude);
$('#ip').html(location.IPv4);
