copied!<p>It is not impossible but it will take some time for code, The way is if you are using for mobile device then you need to accelerator from your device and call geolocation function on position change I think you understand and the second method is from purely javascript method for that you need to call your geolocation function within set Interval understand also draw line separately from marker your marker function only calls within set Intervals for getting your current location with infowindow. Example is :</p> <p>var map;</p> <pre><code>function initialize() { var mapOptions = { zoom: 6, mapTypeId: google.maps.MapTypeId.ROADMAP }; map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions); //keep this in setInterval // Try HTML5 geolocation if(navigator.geolocation) { navigator.geolocation.getCurrentPosition(function(position) { var pos = new google.maps.LatLng(position.coords.latitude, position.coords.longitude); var infowindow = new google.maps.InfoWindow({ map: map, position: pos, content: 'Location found using HTML5.' }); map.setCenter(pos); }, function() { handleNoGeolocation(true); }); } else { // Browser doesn't support Geolocation handleNoGeolocation(false); } } function handleNoGeolocation(errorFlag) { if (errorFlag) { var content = 'Error: The Geolocation service failed.'; } else { var content = 'Error: Your browser doesn\'t support geolocation.'; } var options = { map: map, position: new google.maps.LatLng(60, 105), content: content }; var infowindow = new google.maps.InfoWindow(options); map.setCenter(options.position); } //close here your set interval google.maps.event.addDomListener(window, 'load', initialize); </code></pre>
