I would like to have the map open up a the users current location. I only see documentation for setting the center on init, I would like it to be dynamic..

this example shows how it can be done

add the following function to detect user location

// credit: http://html5doctor.com/finding-your-position-with-geolocation/
function detectUserLocation(){
  if (navigator.geolocation) {
    var timeoutVal = 10 * 1000 * 1000;
      { enableHighAccuracy: true, timeout: timeoutVal, maximumAge: 0 }
  else {
    alert("Geolocation is not supported by this browser");

  function alertError(error) {
    var errors = { 
      1: 'Permission denied',
      2: 'Position unavailable',
      3: 'Request timeout'
    alert("Error: " + errors[error.code]);

if the user allows it, the above function calls mapToPosition to update the map to that location

function mapToPosition(position) {
  lon = position.coords.longitude;
  lat = position.coords.latitude;
  map.setView(new L.LatLng(lat,lon), 7);
  new L.CircleMarker([lat,lon],{radius: 4}).addTo(map);

If you want it to be dynamic, you could trigger detectUserLocation() from a button

$('#button').on('click', detectUserLocation);
