    Html5 provides geolocation API by using which we can display the results in a Map. Following example shows how we can show the Map in html5. To display the result in a map, you need access to a map service, like Google Maps.

    <!DOCTYPE html>
    <p id="mapclick">Click here to get your position in the map</p>
    <button onclick="getLocation()">Try It</button>
    <div id="mapholder"></div>
    <script src=""></script>
    var x = document.getElementById("mapclick");
    function getLocation() {
        if (navigator.geolocation) {
            navigator.geolocation.getCurrentPosition(showPosition, showError);
        } else { 
            x.innerHTML = "Geolocation is not supported by this browser.";
    function showPosition(position) {
        lat = position.coords.latitude;
        lon = position.coords.longitude;
        latlon = new google.maps.LatLng(lat, lon)
        mapholder = document.getElementById('mapholder') = '250px'; = '500px';
        var myOptions = {
        var map = new google.maps.Map(document.getElementById("mapholder"), myOptions);
        var marker = new google.maps.Marker({position:latlon,map:map,title:"You are here!"});
    function showError(error) {
        switch(error.code) {
            case error.PERMISSION_DENIED:
                x.innerHTML = "User denied the request for Geolocation."
            case error.POSITION_UNAVAILABLE:
                x.innerHTML = "Location information is unavailable."
            case error.TIMEOUT:
                x.innerHTML = "The request to get user location timed out."
            case error.UNKNOWN_ERROR:
                x.innerHTML = "An unknown error occurred."
