I am currently creating a small HTML5 and Javascript application. I am using geolocations API and JQuery sortable UI javascript, however they seem to be conflicting. When I open my page, the geolocations map no longer appears.

My index.html file:

My geo.js file

C#

function success(position) {

    return;
  }

  s.innerHTML = "Found You";
  s.className = 'success';

  var mapcanvas = document.createElement('div');
  mapcanvas.id = 'mapcanvas';
  mapcanvas.style.height = '300px';
  mapcanvas.style.width = '100%';

  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!"
  });
}

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');
}

Any help would be much appreciated.

How can you call it HTML5 if it is not?

not sure if this is a solution, so just putting it in the comments section:
I agree with SAKryukov - perhaps its your DOCTYPE declaration - try <!DOCTYPE html>
?
