Hi! Just a curious newbie here. I am proposing a project on our current course and want to deal with jquery incorporated as gps. I don't know if I sound right, but I just want to ask if a realtime gps jquery mobile is possible to program? And what are the necessary things I should have to look after and consider? Thank you very much for your support.

Realtime GPS jQuery Mobile is possible. HTML5 (the latest HTML version) is the standard for jQuery Mobile. You should and learn HTML5 since it's what need. navigator.geolocaton object cause GPS to be available.

 

Lewis, use this code for longitude and latitude.

 

<!DOCTYPE html> 
<html> 
<head> 
  <meta name=viewport content="user-scalable=no,width=device-width" />
  <link rel=stylesheet href=jquery.mobile/jquery.mobile.css />
  <script src=jquery.js></script>
  <script src=jquery.mobile/jquery.mobile.js></script>
</head> 
 
<body> 
 
<div data-role=page id=home>
  <div data-role=header>
    <h1>Home</h1>
  </div>
 
  <div data-role=content>
    <span> Latitude : </span> <span id=lat></span> <br />
    <span> Longitude : </span> <span id=lng></span> <br />
  </div>
</div>
 
</body>
</html>
 
<script>
 
navigator.geolocation.getCurrentPosition (function (pos)
{
  var lat = pos.coords.latitude;
  var lng = pos.coords.longitude;
  $("#lat").text (lat);
  $("#lng").text (lng);
});
 
</script>

Hello!

It is possible to create a jquery GPS for mobile phone, but it may take you some time.

You can use this script for the GPS part:

(function($) {
        $.gps = {
                approximate:function(loc1, loc2, success)
                {
                        x = 69.1 * (loc2.latitude – loc1.latitude);
                        y = 53.0 * (loc2.longitude – loc1.longitude);
 
                        mi = Math.sqrt(x * x + y * y);
                        success(mi);
                },                
                distance:function(loc1, loc2, success)
                {
                        mi = (3963 * 3.1415926 * Math.sqrt(
                                (loc2.latitude–loc1.latitude) *
                                (loc2.latitude–loc1.latitude) +
                                Math.cos(loc2.latitude/57.29578) *
                                Math.cos(loc1.latitude/57.29578) *
                                (loc2.longitude–loc1.longitude) *
                                (loc2.longitude–loc1.longitude)
                        )/180);
 
                        success(mi);
                },
                /* not 100% sure this works properly, just yet */
                minMaxRadii:function(loc, mi, success)
                {
                        lat_mile = 0.0144839 * mi;
                        lon_mile = (0.0144839 / Math.cos(loc.latitude * 3.1415926 / 180 )) * mi;
 
                        var range = {
                                max: {
                                        latitude: loc.latitude + lat_mile,
                                        longitude: loc.longitude + lon_mile
                                },
                                min: {
                                        latitude: loc.latitude – lat_mile,
                                        longitude: loc.longitude – lon_mile
                                }
                        }
 
                        success(range);
                },
                km2mi:function(km){ return km * 0.621371192; },
                mi2km:function(mi){ return mi * 1.609344; }
        }
})(jQuery);
 
It also depends on what programming language you would like to use and on what kind of phone you want to use it.
 
After creating the software, you should use something like this: Location Site
 
To help you get the needed locations.
 
Good luck!
