Google Maps API - Geocode & Search Nearby


I'm trying to merge together a GOOGLE geocoder script and a 'search nearby' script. I cannot seem to merge it successfully. Help?

The geocoder script lies here:

var geocoder;
var map;
function initialize() {
  geocoder = new google.maps.Geocoder();
  var latlng = new google.maps.LatLng(-34.397, 150.644);
  var mapOptions = {
    zoom: 8,
    center: latlng
  }
  map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);
}

function codeAddress() {
  var address = document.getElementById('address').value;
  geocoder.geocode( { 'address': address}, function(results, status) {
    if (status == google.maps.GeocoderStatus.OK) {
      map.setCenter(results[0].geometry.location);
      var marker = new google.maps.Marker({
          map: map,
          position: results[0].geometry.location
      });
    } else {
      alert('Geocode was not successful for the following reason: ' + status);
    }
  });
}

google.maps.event.addDomListener(window, 'load', initialize);

And the search nearby script lies here:

var map;
var infowindow;

function initialize() {
  var pyrmont = new google.maps.LatLng(-33.8665433, 151.1956316);

  map = new google.maps.Map(document.getElementById('map-canvas'), {
    center: pyrmont,
    zoom: 15
  });

  var request = {
    location: pyrmont,
    radius: 500,
    types: ['store']
  };
  infowindow = new google.maps.InfoWindow();
  var service = new google.maps.places.PlacesService(map);
  service.nearbySearch(request, callback);
}

function callback(results, status) {
  if (status == google.maps.places.PlacesServiceStatus.OK) {
    for (var i = 0; i < results.length; i++) {
      createMarker(results[i]);
    }
  }
}

function createMarker(place) {
  var placeLoc = place.geometry.location;
  var marker = new google.maps.Marker({
    map: map,
    position: place.geometry.location
  });

  google.maps.event.addListener(marker, 'click', function() {
    infowindow.setContent(place.name);
    infowindow.open(map, this);
  });
}

google.maps.event.addDomListener(window, 'load', initialize);

So I'm posting on here because I have no idea how to merge them. I tried to merge the scripts together but I couldn't get it to work. Any ideas?

Thanks.


Solution

  • Could be something like this sketch below. Not sexy, but works.

    Don't forget to include the places libary.

    JS

    var geocoder;
    var map;
    var infowindow;
    var pyrmont = new google.maps.LatLng(-33.8665433, 151.1956316);
    
    function initialize() {  
      var latlng = new google.maps.LatLng(-34.397, 150.644);
      var mapOptions = {
        zoom: 8,
        center: latlng
      }
    
     map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);
    
     codeAddress();
    
      var request = {
        location: pyrmont,
        radius: 500,
        types: ['store']
      };
    
      infowindow = new google.maps.InfoWindow();
      var service = new google.maps.places.PlacesService(map);
      service.nearbySearch(request, callback);
    }
    
    
    function codeAddress() {
      geocoder = new google.maps.Geocoder();  
      var address = '100 Murray St, Pyrmont NSW, Australia';   
      geocoder.geocode( { 'address': address}, function(results, status) {
        if (status == google.maps.GeocoderStatus.OK) {
          map.setCenter(results[0].geometry.location);
          var marker = new google.maps.Marker({
              map: map,
              position: results[0].geometry.location
          });
        } else {
          alert('Geocode was not successful for the following reason: ' + status);
        }
      });
    }
    
    function callback(results, status) {
      if (status == google.maps.places.PlacesServiceStatus.OK) {
        for (var i = 0; i < results.length; i++) {
          createMarker(results[i]);
        }
      }
    }
    
    function createMarker(place) {
      var placeLoc = place.geometry.location;
      var marker = new google.maps.Marker({
        map: map,
        position: place.geometry.location
      });
    
      google.maps.event.addListener(marker, 'click', function() {
        infowindow.setContent(place.name);
        infowindow.open(map, this);
      });
    }
    
    google.maps.event.addDomListener(window, 'load', initialize);

    EDIT:

    Or you can simply copy and paste this html file, this should work.

    EDIT 2:

    First geocode the address and then show places nearby.

    var geocoder;
    var map;
    var infowindow;
    //var pyrmont = new google.maps.LatLng(-33.8665433, 151.1956316);
    var nearbysearchloc = '';
    
    function initialize() {  
      var latlng = new google.maps.LatLng(-34.397, 150.644);
      var mapOptions = {
        zoom: 8,
        center: latlng
      }
      map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);
    codeAddress();
    }
    
    function codeAddress() {
      geocoder = new google.maps.Geocoder();  
      var address = '100 Murray St, Pyrmont NSW, Australia';   
      geocoder.geocode( { 'address': address}, function(results, status) {
        if (status == google.maps.GeocoderStatus.OK) {
          map.setCenter(results[0].geometry.location);        
          var marker = new google.maps.Marker({

      });
    }
    
    function ParseLocation(location) {
          var lat = location.lat().toString().substr(0, 12);
          var lng = location.lng().toString().substr(0, 12);
    
    nearbysearchloc = new google.maps.LatLng(lat, lng);
    ShowPlacesAroundMe(nearbysearchloc);
    }
    
    function ShowPlacesAroundMe(location){
    var request = {
        location: location,
        radius: 500,
        types: ['store']
      };
      infowindow = new google.maps.InfoWindow();
      var service = new google.maps.places.PlacesService(map);
      service.nearbySearch(request, callback);    
    
    }
    
    google.maps.event.addDomListener(window, 'load', initialize);
