HTML5 Geolocation API lets you share your location with your favorite websites. A JavaScript can capture your latitude and longitude and can be sent to backend web server and do fancy location-aware things like finding local businesses or showing your location on a map.
The geolocation APIs work with a new property of the global navigator object ie. Geolocation object.
The getCurrentPosition method retrieves the current geographic location of the device. The location is expressed as a set of geographic coordinates together with information about heading and speed. The location information is returned to a Position object.
Example
You can try to run the following code to find the current location:
<!DOCTYPE HTML> <html> <head> <script type = "text/javascript"> 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>
