Title Body

I'm using navigator.geolocation.watchPosition in JavaScript, and I want a way to deal with the possibility that the user might submit a form relying on location before watchPosition has found its location. Ideally the user would see a 'Waiting for location' message periodically until the location was obtained, then the form would submit. However, I'm not sure how to implement this in JavaScript given its lack of a wait function. Current code: var current_latlng = null; function gpsSuccess(pos){ //console.log('gpsSuccess'); if (pos.coords) { lat = pos.coords.latitude; lng = pos.coords.longitude; } else { lat = pos.latitude; lng = pos.longitude; } current_latlng = new google.maps.LatLng(lat, lng); } watchId = navigator.geolocation.watchPosition(gpsSuccess, gpsFail, {timeout:5000, maximumAge: 300000}); $('#route-form').submit(function(event) { // User submits form, we need their location... while(current_location==null) { toastMessage('Waiting for your location...'); wait(500); // What should I use instead? } // Continue with location found... });
