HTML5 Geolocation API lets you share your location with your favorite web sites. A JavaScript can capture your latitude and longitude, can be sent to backend web server, and do fancy location-aware things like finding local businesses or showing your location on a map.
Example
Let us see how to get the current position −
<!DOCTYPE HTML> <html> <head> <script> function showLocation(position) { var latitude = position.coords.latitude; var longitude = position.coords.longitude; alert("Latitude : " + latitude + " Longitude: " + longitude); } function errorHandler(err) { if(err.code == 1) { alert("Error: Access is denied!"); } else if( err.code == 2) { alert("Error: Position is unavailable!"); } } function getLocation(){ if(navigator.geolocation){ // timeout at 60000 milliseconds (60 seconds) var options = {timeout:60000}; navigator.geolocation.getCurrentPosition(showLocation, errorHandler, options); } else{ alert("Sorry, browser does not support geolocation!"); } } </script> </head> <body> <form> <input type="button" onclick="getLocation();" value="Get Location"/> </form> </body> </html>
