  • 0

I have a small Google maps v3 script that works fine on all proper browsers, but when it encounters IE I get a “object expected” error no matter what event handler I use or different way of writing the attributes. Help!

The script here:

function include(filename)
{
    var head = document.getElementsByTagName('head')[0];

    script = document.createElement('script');
    script.src = filename;
    script.type = 'text/javascript';

    head.appendChild(script)
}


include('geoxml3.js');
include('v3_epoly.js');

  var geoXml = null;
    var map = null;
    var geocoder = null;
    var toggleState = 1;
    var infowindow = null;
    var marker = null;
    var Ploc = null;
    var directionDisplay;
    var directionsService = new google.maps.DirectionsService();
//Voting Locations: Array element id = voting pct!
    var Vloc = new Array();
        Vloc[1] = 's';
        Vloc[2] = 's';
        Vloc[3] = 's';
        Vloc[4] = 's';


 function initialize() {
    directionsDisplay = new google.maps.DirectionsRenderer();  
    geocoder = new google.maps.Geocoder();
    infowindow = new google.maps.InfoWindow({size: new google.maps.Size(150,50) }); 
    var latlng = new google.maps.LatLng(32.5890, -96.308871);

          map.setCenter(point);
          if (marker && marker.setMap) marker.setMap(null);
          marker = new google.maps.Marker({
              map: map, 
              position: point
          });
        for (var i=0; i<geoXml.docs[0].gpolygons.length; i++) {
          if (geoXml.docs[0].gpolygons[i].Contains(point)) {
            contentString = address+'<br>'+geoXml.docs[0].placemarks[i].name;

            i = 999; // Jump out of loop
          }
        }

    I handled the event with:
    google.setOnLoadCallback(initialize); and it displays fine in IE 8/9.
