Google maps responsive resize

Question

I'm trying to get google maps responsive and resize while keeping its center when windows resizes. I read other stack questions in regards such as:

Responsive Google Map? and Center Google Maps (V3) on browser resize (responsive)

from the second stack question I got a link which helps me with part of the code but I still have no luck. This is the code I am using, when I resize the window, the maps doesn't resize at all

    function initialize() {       var mapOptions = {        center: new google.maps.LatLng(40.5472,12.282715),        zoom: 6,        mapTypeId: google.maps.MapTypeId.ROADMAP       };       var map = new google.maps.Map(document.getElementById("map-canvas"),                 mapOptions);     }     google.maps.event.addDomListener(window, 'load', initialize);     google.maps.event.addDomListener(window, "resize", function() {      var center = map.getCenter();      google.maps.event.trigger(map, "resize");      map.setCenter(center);      }); 

html

 <div id="map-canvas"/> 

css

html { height: 100% } body { height: 100%; margin: 0; padding: 0; } #map-canvas { height: 100%; }

Move your map variable into a scope where the event listener can use it. You are creating the map inside your initialize() function and nothing else can use it when created that way.

var map; //<-- This is now available to both event listeners and the initialize() function function initialize() {   var mapOptions = {    center: new google.maps.LatLng(40.5472,12.282715),    zoom: 6,    mapTypeId: google.maps.MapTypeId.ROADMAP   };   map = new google.maps.Map(document.getElementById("map-canvas"),             mapOptions); } google.maps.event.addDomListener(window, 'load', initialize); google.maps.event.addDomListener(window, "resize", function() {  var center = map.getCenter();  google.maps.event.trigger(map, "resize");  map.setCenter(center);  });
