Google Maps API issue with IE8 - javascript

I'm writing some code with the Google Maps API, it works fine in all browsers (FF, IE9, Chrome) but IE8 or below, I have assigned the map to a global variable called Map, which gets populated but when the addMarker function gets called the Map global is null in IE8, but the addMarker function does work when I call it from the locator function, I have included all these functions below.
var GoogleMaps = {};
var Map = null;
var init = (function () {
"use strict";
var MapType = null;
var ZoomLevel = null;
var ControlPos = null;
var ControlSize = null;
var myLatLong = null;
var Geocoder;
var result = null;
GoogleMaps.setup = function (options) {
myLatLong = new google.maps.LatLng(24.886436490787712, -70.26855468754);
if (google.loader.ClientLocation) {
myLatLong = new google.maps.LatLng(
google.loader.ClientLocation.latitude,
google.loader.ClientLocation.longitude);
} else if (options.Lat !== null && options.Long !== null) {
options.Location = new google.maps.LatLng(options.Lat, options.Long);
} else {
// Else centre to UK
options.Location = new google.maps.LatLng(52.961875, -1.419433);
}
if (options.MapType.toUpperCase() === 'ROADMAP') {
MapType = google.maps.MapTypeId.ROADMAP;
} else if (options.MapType.toUpperCase() === 'TERRAIN') {
MapType = google.maps.MapTypeId.TERRAIN;
} else if (options.MapType.toUpperCase() === 'HYBRID') {
MapType = google.maps.MapTypeId.HYBRID;
} else {
MapType = google.maps.MapTypeId.SATELLITE;
}
// Check zoom level, if not set then set to zoom level 8.
if (options.ZoomLevel) {
ZoomLevel = options.ZoomLevel;
} else {
ZoomLevel = 8;
}
var mapOptions = {
center: myLatLong,
zoom: ZoomLevel,
mapTypeId: MapType
};
var mapDiv = document.getElementById('canvas');
// Map gets initiated here
window.Map = new google.maps.Map(mapDiv, mapOptions);
delete options.MapType;
delete options.Lat;
delete options.Long;
delete options.ZoomLevel;
};
GoogleMaps.addMarker = function (options) {
var Location = null;
var Animation = null;
var Title = null;
var Draggable = null;
var Content = null;
var InfoWindow = null;
var Flat = null;
var Clickable = null;
if (options.lat !== null && options.long !== null) {

} else {

} else {

}
if (options.draggable !== null && options.draggable === 'true') {
Draggable = true;
} else {
Draggable = false;
}
if (options.title !== null) {

} else {
Title = null;
}
if (options.content !== null) {

InfoWindow = new google.maps.InfoWindow({
content: Content
});
}
if (options.flat !== null && options.flat === 'true') {
Flat = true;
} else {
Flat = false;
}
if (options.clickable !== null && options.clickable === 'true') {
Clickable = true;
} else {
Clickable = false;
}
// Gets used in this section
var Marker = new google.maps.Marker({
position: Location,
map: window.Map,
animation: Animation,
draggable: Draggable,
title: Title,
flat: Flat,
clickable: Clickable,
zIndex: 1
});
// and sets map here
Marker.setMap(window.Map);
if (options.content !== null) {
google.maps.event.addListener(Marker, 'click', function (e) {
InfoWindow.open(window.Map, this);
google.maps.event.addListener(window.Map, 'click', function (e) {
InfoWindow.close(window.Map, window.Marker);
});
});
}
google.maps.event.addListener(Marker, 'dragend', function (e) {
});
delete options.lat;
delete options.long;
delete options.animation;
delete options.title;
delete options.content;
delete options.flat;
delete options.draggable;
delete options.clickable;
};
GoogleMaps.Locator = function (result) {
var address = null;
Geocoder = new google.maps.Geocoder();
address = result;
Geocoder.geocode({ 'address': address }, function (response, status) {
if (status === google.maps.GeocoderStatus.OK) {
window.Map.setCenter(response[0].geometry.location);
var Location = new google.maps.LatLng(response[0].geometry.location.Xa, response[0].geometry.location.Ya);
var markerOptions = {
animation: "drop",
draggable: "true",
content: 'Hello World!',
title: "Hello",
position: Location
};
GoogleMaps.addMarker(markerOptions);
} else {
alert("Geocode was not successful for the following reason: " + status);
}
});
};
Below is how I am calling the functions:
var markerOptions = {
lat: 52.48278,
long: -0.892089,
animation: "drop",
draggable: "true",
content: 'Hello World!',
title: "Click Me"
};
google.maps.event.addDomListener(window, 'load', function () { GoogleMaps.setMarker(markerOptions) });
google.maps.event.addDomListener(window, 'load', function () { GoogleMaps.Locator('London') });
Thanks for any help.

I resolved the problem like this.
<meta http-equiv=”X-UA-Compatible” content=”IE=EmulateIE7; IE=EmulateIE9″/>

Try changing this line in your setup
window.Map = new google.maps.Map(mapDiv, mapOptions);
to just
Map = new google.maps.Map(mapDiv, mapOptions);
This way you accessing the global variable declared.

when is GoogleMaps.setup called? Right now it looks like depending on the browser it can be called after functions attached by
google.maps.event.addDomListener(window, 'load', function () { ... });
and that's why map is not set when you call addMarker, but is already initialized when you receive callback from
Geocoder.geocode(...)
To fix this make sure that GoogleMaps.setup is called before addMarker.

IE8 has always meant trouble. :-) Try adding the following meta tag at the beginning of your <head> section:
<meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7" />

Displaying BBOX hash in URL

I think I'm doing something wrong in the variables or syntax... i don't know, help me to correct my code. (I'm using Leaflet for the map show)
Desired Behavior
The user should be able to see the BBOX entering the coordinates into the URL, for example:
.com/#013.0,052.0,013.5,052.5
I only care that the BBOX is shown, I don't care that the URL coordinates change when zooming or moving around the map.

Setting state for Google Maps using map type, selected marker, and zoom level loaded from local storage

I am customizing the WordPress Geodirectory plugin's Google Maps API functionality to store the user set/selected map type, marker, and zoom level in local storage.
I have the user set map type and zoom level functionality working, but am struggling with implementing the selected map marker.
How would I go about storing and retrieving the selected map marker from local storage and displaying it on the map when the user clicks/taps back in the browser?
My existing custom code is included below:
const zoomChangeListener = google.maps.event.addListener(jQuery.goMap.map, 'zoom_changed', function (event) {
storeUserZoom();
});
loadUserZoom();
function storeUserZoom() {
let zoom = jQuery.goMap.map.getZoom();
localStorage.setItem( 'zoom', zoom);
// console.log('Storing zoom level: ' + zoom);
}
function loadUserZoom() {
let zoom = localStorage.getItem( 'zoom' );
if (localStorage.getItem( 'zoom' )) {
jQuery.goMap.map.setZoom(parseInt(zoom));
// console.log('Local storage zoom level: ' + zoom);
}
}
const mapTypeChangeListener = google.maps.event.addListener(jQuery.goMap.map, 'maptypeid_changed', function (event) {
storeUserMapType();
});
loadUserMapType();
function storeUserMapType() {
let mapType = jQuery.goMap.map.getMapTypeId();
localStorage.setItem( 'maptype', mapType);
// console.log('Map type changed: ' + mapType);
}
function loadUserMapType() {
let mapType = localStorage.getItem( 'maptype' );
if (localStorage.getItem( 'maptype' )) {
jQuery.goMap.map.setMapTypeId(mapType);
// console.log('Loading map type: ' + mapType);
}
}
function storeUserMarker(item, map_canvas) {
let markerId, markerTitle, markerIcon, markerPosition;
markerId = item.id;
markerTitle = item.title;
markerIcon = item.icon = {
url: item.icon,
// scaledSize: new google.maps.Size(resizeW, resizeH),
origin: new google.maps.Point(0, 0),
anchor: new google.maps.Point(0, 0)
};
// markerIcon = item.icon;
// console.log(markerIcon);
markerPosition = item.position;
localStorage.setItem( 'id', markerId );
localStorage.setItem( 'title', markerTitle );
localStorage.setItem( 'icon', JSON.stringify(markerIcon) );
localStorage.setItem( 'position', JSON.stringify(markerPosition));

The loadUserMarker(); function returns [object Object] in the console when executed.
The functionality can be tested on the staging site. Try clicking on a map marker, visiting the individual page, then return to the map with the browser back button.
Update
I am receiving the following error when trying to load the previously clicked/tapped map marker: Uncaught (in promise) TypeError: b.anchor.get is not a function. I know it relates to anchoring the info window to the map marker, but I am not sure how to correct it.
My storeUserMarker function has been updated to make item.icon into an object that includes the marker URL, origin, and anchor.
How would I go about getting the marker's anchor data so the info window can be displayed?

Is it because of the order of my code? I tried playing around with the order and could not find a solution. Any help would be appreciated. Thanks in advance!

Google Maps Multiple markers with the exact same location Not working
Many Many Thanks
That solution is great, but I'd take a look at using the Overlapping Marker Spiderfier library to handle markers in the same location. You can use this in conjunction with the marker clusterer library, without any issues. This way you also don't lose the ability to see how many markers are actually in that same location - and it gives you a great UI in my opinion.
To use Overlapping Marker Spiderfier, include the script file before your main js file in your html. Then in your js, create an instance of the OverlappingMarkerSpiderfier object:
var oms = new OverlappingMarkerSpiderfier(map);
/*in your case I'd do this after you initialize the `map` object,
*and declare the `oms` globally, like you do with your other global objects
*/
Then when the markers are created, you want to add the marker to the oms object via the addMarker() method. So, in your case add the following line to the renderElements() function after the click event listener you declare for the marker:
oms.addMarker(marker);
Lastly, make sure to also clear the markers from the oms object when the removeMarkers() function in your code is called by adding the following to that function:
oms.clearMarkers();
