Get current location of a visitor

Question

I already found functionality that can give a users country or state using his or her IP address. But what I actually need is the exact location.

Like you can see on this link, it is possible to get the very specific current location of a user.

How is this possible with ASP.NET C#, Javascript or jQuery?

You could use the Geolocation API in JavaScript ... to get the current position use this :

navigator.geolocation.getCurrentPosition(function(position) {
  do_something(position.coords.latitude, position.coords.longitude);
});

do_something() could be to update a map or just show the current longitude and latitude. Nice simple example here

Browser support (Source):

Firefox 3.5+
Chrome 5.0+
Safari 5.0+
Opera 10.60+
Internet Explorer 9.0+

I'd upvote twice if I could since you DIDN'T refer to it as HTML5! :-) – Ian Devlin Jun 12 '12 at 09:04
Do you know how Google makes this possible to know the users exact location without GPS or something? – Ozkan Jun 12 '12 at 09:11

  navigator.geolocation.getCurrentPosition(
      onSuccess,
      onError, {
        enableHighAccuracy: true,
        timeout: 20000,
        maximumAge: 120000
      });

function onSuccess(position) {
      //the following are available to use
  //position.coords.latitude
  //position.coords.longitude
 // position.coords.altitude
 // position.coords.accuracy
 // position.coords.altitudeAccuracy
 // position.coords.heading
 // position.coords.speed 


}
