Google Maps can't read property 'extend' of undefined after page load

I'm trying to increase page speed by loading my Google Maps two seconds after page load. While doing so, I keep on getting "Cannot read property 'extend' of undefined". I know there is some asynchronous loading going on but I'm not sure how to get it in proper order to get this map to load 2 seconds after the page is done. Any help is greatly appreciated.
Page Code:
<div id="mapCont"></div>

The initial https://maps.googleapis.com/maps/api/js?key=key loads additional scripts that are not being captured by your implementation. The package, https://www.npmjs.com/package/#googlemaps/js-api-loader, enables the following pattern and is probably what you want:
import { Loader } from '#googlemaps/js-api-loader';
const loader = new Loader({
apiKey: "",
version: "weekly",
libraries: ["places"]
});
loader
.load()
.then(() => {
doMap();
initialize();
})
.catch(e => {
// do something
});
Alternative(use callback) if you want JQuery and your existing pattern:
window.callback = () => {
doMap();
initialize();
};
$(window).bind("load", function() {
$.getScript('https://maps.googleapis.com/maps/api/js?key=key&callback=callback', () => {}); // do nothing here

On click event google map add marker Extjs

Hello I click event Implemented but nothing hapens.I am using MVC Extjs I know how to implement in javascript for examplejsfiddle simple click event but in extjs where I should put the code I have gmappanel in window how to handle this in controller I have no idea how to do it... Help Where I should put this code:
var map = Ext.getCmp('gmapForm');
google.maps.event.addListener(map, 'click', function(e) {
var lat = e.latLng.lat(); // lat of clicked point
var lng = e.latLng.lng(); // lng of clicked point
var markerId = getMarkerUniqueId(lat, lng); // an that will be used to cache this marker in markers object.
var marker = new google.maps.Marker({
position: getLatLng(lat, lng),
map: map,
id: 'marker_' + markerId
});
});
here is my view with not working listeners no one works I wondered:

Google Maps API: Multiple GeoJson layers with MarkerClusterer + toggle

I have a problem with my GeoJson layers which I want to cluster (with MarkerClusterer) and then be able to show and hide them via checkboxes or similar. Therefore I tried something like the code below:
function initialize() {
var mapOptions = {
center: new google.maps.LatLng(52.515696, 13.392624),
zoom: 11,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("map"),
mapOptions);
var bounds = new google.maps.LatLngBounds();
var barLayer = new google.maps.Data();
var cafeLayer = new google.maps.Data();
barLayer.loadGeoJson('json/eat_drink/bar.geojson');
cafeLayer.loadGeoJson('json/eat_drink/cafe.geojson');
var markerClusterer = new MarkerClusterer(map);
var infowindow = new google.maps.InfoWindow();
markerClusterer.setMap(map);
function displayMarkers(layer) {
var layer = layer;
google.maps.event.addListener(layer, 'addfeature', function (e) {
if (e.feature.getGeometry().getType() === 'Point') {
var marker = new google.maps.Marker({
position: e.feature.getGeometry().get(),
title: e.feature.getProperty('name'),
map: map
});
// open the infoWindow when the marker is clicked
google.maps.event.addListener(marker, 'click', function (marker, e) {
return function () {
var myHTML = e.feature.getProperty('name');
infowindow.setContent("<div style='width:150px; text-align: center;'>"+myHTML+"</div>");
infowindow.setPosition(e.feature.getGeometry().get());
infowindow.setOptions({pixelOffset: new google.maps.Size(0,-30)});
infowindow.open(map, marker);
};
}(marker, e));
markerClusterer.addMarker(marker);
bounds.extend(e.feature.getGeometry().get());
map.fitBounds(bounds);
map.setCenter(e.feature.getGeometry().get());
}
});
layer.setMap(null);
google.maps.event.addListener(map, "click", function () {
infowindow.close();
});
};
document.getElementById('bar').onclick = function(){ // enable and disable markers
if(document.getElementById('bar').checked == true){
displayMarkers(barLayer);
}else{
return null;
}
};
}
Unfortunatley this doesn't work and I don't no exactly why.
If I remove the displayMarkers() function around the code and replace "layer" with the desired GeoJson layer, e.g. "barLayer", it works just fine.
Since I will end up with tons of GeoJason layers I would prefer a "compact" solution like this insted of copying the code multiple times. Have you guys any ideas how to do that properly?

I'm afraid I haven't done much more than refactor your code. Could you give this a try, and if it doesn't work specify exactly what doesn't work?
function displayMarkers(layer, map, markerClusterer) {
google.maps.event.addListener(layer, 'addfeature', function(e) {
if (e.feature.getGeometry().getType() === 'Point') {
var marker = new google.maps.Marker({
position: e.feature.getGeometry().get(),
title: e.feature.getProperty('name'),
map: map
});
// open the infoBox when the marker is clicked
google.maps.event.addListener(marker, 'click', function(e) {
var myHTML = e.feature.getProperty('name');
var infowindow = new google.maps.InfoWindow();
infowindow.setContent("<div style='width:150px; text-align: center;'>" + myHTML + "</div>");
infowindow.setPosition(e.feature.getGeometry().get());
infowindow.setOptions({
pixelOffset: new google.maps.Size(0, -30)
});
infowindow.open(map, marker);
google.maps.event.addListener(map, "click", function() {
infowindow.close();
});
});
markerClusterer.addMarker(marker);
var bounds = new google.maps.LatLngBounds();
bounds.extend(e.feature.getGeometry().get());
map.fitBounds(bounds);
map.setCenter(e.feature.getGeometry().get());
}
});
layer.setMap(null);
}
function initialize() {
var mapOptions = {
center: new google.maps.LatLng(52.515696, 13.392624),
zoom: 11,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("map"), mapOptions);
var barLayer = new google.maps.Data();
var cafeLayer = new google.maps.Data();
barLayer.loadGeoJson('json/eat_drink/bar.geojson');
cafeLayer.loadGeoJson('json/eat_drink/cafe.geojson');
var markerClusterer = new MarkerClusterer(map);
markerClusterer.setMap(map);
document.getElementById('bar').onclick = function() { // enable and disable streetViewControl
if (document.getElementById('bar').checked == true) {
displayMarkers(barlayer, map, markerClusterer);
} else {
return null;
}
};
}

Googlemaps API loads slow with many markers

Im trying to load around 600 googlemap markers on page load using the function addMarker.
The page takes a lot of time to load.
Is there anything I can do to make it load faster while keep using the addMarker function?
Thanks.

}
});
google.maps.event.addDomListener(zoomin, "click", function() {

You can use clustering, it joins neighbor markers into one, and expand only on zoom
You can do clustering in client side, as well as server side, depending the amount of markers...
I would suggest to use server clustering if amount is more than 4000, otherwise client should look fine

Infobubble Keep Adding tab and Not removing the previous tab added

I encountered this problem and I'm new on using Infobubble for Google Maps and when i click the marker and add tab, when i change the marker clicked the Previous tab still show
all i want is to remove the previous tab.
This is my Snippet:
function codeAddress() {
infoBubble = new InfoBubble({
map: map,
shadowStyle: 0,
padding: 10,
borderRadius: 10,
arrowSize: 15,
maxWidth: 300,
borderWidth: 1,
borderColor: '#ccc',
arrowPosition: 30,
arrowStyle: 0
});
$.getJSON('/Dashboard/LoadWorkerList', function (address) {
$.each(address, function () {
var currVal = this["AddressLine1"];
var Name = this["Name"];
var Gender = this["Gender"];
var Bdate = this["Birthdate"];
geocoder.geocode({ 'address': currVal }, function (results, status) {
if (status == google.maps.GeocoderStatus.OK) {
var marker = new google.maps.Marker({
map: map,
icon: iconBase + 'man.png',
position: results[0].geometry.location,
title: currVal
})
$('#places').append($('<li>')
.text(currVal)
.data('location', results[0].geometry.location));
google.maps.event.addListener(map, 'bounds_changed', function () {
$('#places li').css('display', function () {
return (map.getBounds().contains($(this).data('location')))
? ''
: 'none';
});
});
//mgr = new MarkerManager(map);
google.maps.event.addListener(marker, 'click', (function (marker, i) {
return function () {
infoBubble.addTab(Name, Name + "" + currVal + "" + Gender + "" + Bdate);
infoBubble.open(map, marker);
}
})(marker, currVal));
address.push(marker);
}
else if (status == google.maps.GeocoderStatus.OVER_QUERY_LIMIT) {
setTimeout(codeAddress, 2000);
}
else {
alert("Geocode was not successful for the following reason: " + status);
}
});
});
google.maps.event.trigger(map, 'bounds_changed');
});
}
As you can see. the tab for Britney Spears is there on the marker of Miley Cyrus.
All i want is to remove the first clicked marker tab

why don't you try something like this instead of adding tabs to one infowindow and changing it's location each time?
var myLatlng = new google.maps.LatLng(latValue, longValue);
var mapOptions = {
...
center: myLatlng
};
var map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);
var infoBubble = null;
...
google.maps.event.addListener(marker, 'click', function() {
if (infoBubble) {
infoBubble.close();
}
infoBubble = new google.maps.InfoWindow({content: singersTextContent});
infoBubble.open(map, marker);
...
});
