Form Tutorial 4 - Geolocation Feature using Google Maps

Hi there,

I try something last week where i put geolocation  in mt JOGET form. First it was hard but luckily i found some sample that i can use using Google ( I <3 U).

Here are the codes and paste it into joget form using 'Custom HTML' element:

<script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script>

<article>
<p>Finding your location: <span id="status">checking...</span></p>
</article>
 
<script>
function success(position) {
var s = document.querySelector('#status');
 
if (s.className == 'success') {
// not sure why we're hitting this twice in FF, I think it's to do with a cached result coming back   
return;
}
 
s.innerHTML = "found you!" + "<br/>Latitude:" + position.coords.latitude + "<br>Longitude: " + position.coords.longitude;
s.className = 'success';
 
var mapcanvas = document.createElement('div');
mapcanvas.id = 'mapcanvas';
mapcanvas.style.height = '400px';
mapcanvas.style.width = '800px';
   
document.querySelector('article').appendChild(mapcanvas);
 
var latlng = new google.maps.LatLng(position.coords.latitude, position.coords.longitude);
var myOptions = {
zoom: 15,
center: latlng,
mapTypeControl: false,
navigationControlOptions: {style: google.maps.NavigationControlStyle.SMALL},
    mapTypeId: google.maps.MapTypeId.ROADMAP
  };
var map = new google.maps.Map(document.getElementById("mapcanvas"), myOptions);
 
var marker = new google.maps.Marker({
      position: latlng,
      map: map,
      title:"You are here! (at least within a "+position.coords.accuracy+" meter radius)"
  });
}

function error(msg) {
var s = document.querySelector('#status');
s.innerHTML = typeof msg == 'string' ? msg : "failed";
s.className = 'fail';
 
// console.log(arguments);
}

if (navigator.geolocation) {
navigator.geolocation.getCurrentPosition(success, error);
} else {
error('not supported');
}

var gaJsHost = (("https:" == document.location.protocol) ? "https://ssl." : "http://www.");
document.write(unescape("%3Cscript src='" + gaJsHost + "google-analytics.com/ga.js' type='text/javascript'%3E%3C/script%3E"));
</script>
<script>
try {
var pageTracker = _gat._getTracker("UA-1656750-18");
pageTracker._trackPageview();
} catch(err) {}</script>

<script>
$('input[name=latitude').val(position.coords.latitude); 
$('input[name=langtitude').val(position.coords.longitude);
</script>

Below is my result:

Note: The system read the location based on IP address. So it may not accurate. Read Google description about this feature
