My app js

//Lat and Long Lookup

 function gpslookup() {
 navigator.geolocation.getCurrentPosition(onSuccess, onError, { enableHighAccuracy: true });
 }

 var latitude = position.coords.latitude;
 var longitude = position.coords.longitude;

//Writing Lat and Long to Page
 document.getElementById("latbox").value = latitude;
 document.getElementById("longbox").value = longitude;

//Ajax call
 var mapquesturl = http:/\/www.mapquestapi.com/geocoding/v1/reverse?key=YOUR_KEY_HERE

  function reverselookup() {
    //httpRequest.onreadystatechange = ReverseLookup;
    httpRequest.open('GET', http:/\/www.mapquestapi.com/geocoding/v1/reverse?key=YOUR_KEY_HERE&renderReverse);
    httpRequest.send(location:{latLng:{lat:latitude,lng:longitude}});
  }

//Write Address to page

 var address =
 var city =
 var state =
 var zip =

 document.getElementById("addressbox").value = address;
 document.getElementById("citybox").value = city;
 document.getElementById("statebox").value = state;
 document.getElementById("zipbox").value = zip;

//Maybe repeat function every 5 secs?

 do {
  function(gpslookup);
  function(reverselookup);
  setTimeout(function(), 5000);
 }
 while (0<1)
