Question

I have created a sample here to show the issue….

http://bit.ly/j2nb1k

The code is js so you can see it in full. In any modern browser including IE9 it works fine. But I get an annoying “undefined is null or not an object” if you load this in IE8 or below.

What am I missing here?

Source below…

var map;
  function initialize() {

    var latlng = new google.maps.LatLng(51, -1);
    var myOptions = {
      zoom: 2,
      center: latlng,
      mapTypeId: google.maps.MapTypeId.ROADMAP
    };
    map = new google.maps.Map(document.getElementById("map_canvas"),
        myOptions);

   vaacinit();
  }

function vaacinit() {

Answer 1

Your arrays end in commas – which is not valid and will throw off versions of IE

For example, compare:

var notValidArray = [1,2,3,];

vs

var validArray = [1,2,3];
