Looks like you might be looking for just regular geolocation stuff? Here's my snippett from a project to grab a user's lat/long

trigger show_user_location(); to begin the geolocation API.

function show_user_location(){ 

    navigator.geolocation.getCurrentPosition(display_user_location, error_response); 
} 
function display_user_location(user_position){ 
    var lat = user_position.coords.latitude; 
    var lon = user_position.coords.longitude; 

// once we get here make that AJAX query
// #loc.value="
Your latitude is: "+lat+", your longitude is: "+lon+"
"+ "
View your location on Google Maps
";

    // I often put the lat/lon in a hidden form for later retrieval here.
    // value = document.getElementById('lat').value;
    // value = document.getElementById('lat').value;

    document.getElementById("lat").value = lat;
    document.getElementById("long").value = lon;

}
