Two googlemaps box in the same javascript file with different locations

I'm trying to find MY MISTAKE in my code:
I want to add to maps to the same script file and I was able to do that with a conditional statement but, when I get to the part of the locations and markers, I'm not able to display my pins, my info windows, and icons.
Here's my code:
var map, locs;
function initMap() {
if (document.getElementById('map')) {
map = new google.maps.Map(document.getElementById('map'), {
center: {lat: 01, lng: -01},
zoom: 15
});
var image = 'http:myimage.png';
var locations = [
['<div class="OzwZjf-jRmmHf-MZArnb-KDwhZb fO2voc-jRmmHf-LJTIlf"><p>My Location</p>' 49.27597, -123.1185, 1]];
var infowindow = new google.maps.InfoWindow();
var marker, i;
for (i = 0; i < locations.length; i++) {
marker = new google.maps.Marker({
position: new google.maps.LatLng(locations[i][1], locations[i][2]),
map: map,
icon: image
});
google.maps.event.addListener(marker, 'click', (function(marker, i) {
return function() {
infowindow.setContent(locations[i][0]);
infowindow.open(map, marker);
}
})(marker, i));
}
} else if (document.getElementById('locs')) {
locs = new google.maps.Map(document.getElementById('locs'), {
center: {lat:02, lng: -02},
zoom: 4
});
var image = 'http:myimage.png';
var locations_two = [
['<div class="OzwZjf-jRmmHf-MZArnb-KDwhZb fO2voc-jRmmHf-LJTIlf"><p>My Location</p>' 02, -02, 1]];
var infowindow = new google.maps.InfoWindow();
var marker_two, i;
for (i = 0; i < locations_two.length; i++) {
marker_two = new google.maps.Marker({
position: new google.maps.LatLng(locations_two[i][1], locations_two[i][2]),
map: map,
icon: image
});
google.maps.event.addListener(marker_two, 'click', (function(marker, i) {
return function() {
infowindow.setContent(locations_two[i][0]);
infowindow.open(map, marker);
}
})(marker_two, i));
}
}
}
google.maps.event.addDomListener(window, "load", initMap);
#map {height: 500px;}
#locs {height: 500px;}
<script src="https://maps.googleapis.com/maps/api/js"></script>
<div id="map"><div>
<div id="locs"><div>
Both maps are in a different page, I'm able to see only the first one with locations, the second one come without location, markers and info windows.

Change
marker_two = new google.maps.Marker({
position: new google.maps.LatLng(locations_two[i][1], locations_two[i][2]),
map: map,
icon: image
});
to
marker_two = new google.maps.Marker({
position: new google.maps.LatLng(locations_two[i][1], locations_two[i][2]),
map: locs,
icon: image
});
You need to use locs because that is the second map object that you create and that is what you need to pass while creating the marker instead of map.
Also 01, 02 are not valid float values. You need to change them to 1, 2 which will make them valid float numbers.

Adding labels and icons on google maps markers

How can I add labels to my two markers so that when you click on the marker it shows you more details about it and also how can I change the icon of the "Access Point 2" to a different marker
function initialize() {
var myLatlng = new google.maps.LatLng(-26.322402,31.142249),
map = new google.maps.Map(document.getElementById('google-map-default'), {
zoom: 14,
center: myLatlng
}),
marker = new google.maps.Marker({
position: myLatlng,
map: map,
title: "We are here!"
});
var accessPoint1 = new google.maps.LatLng(-26.315402,31.123924),
marker1 = new google.maps.Marker({
position: accessPoint1,
map: map,
title: "Access Point 1"
});
var accessPoint2 = new google.maps.LatLng(-26.316700,31.138043),
marker2 = new google.maps.Marker({
position: accessPoint2,
map: map,
title: "Access Point 2"
});
}
google.maps.event.addDomListener(window, 'load', initialize);
#google-map-default {
height: 200px;
}
<div id="google-map-default"></div>
<script src="https://maps.googleapis.com/maps/api/js"></script>
the code above is in a file called maps.mini.js which is currently working fine. I just need to make modifications on it as specified above

Here is a probably more robust and extendable solution that makes use of an array holding your locations (markers), and a single InfoWindow object. With this, you can add as many locations as you need without having to duplicate the rest of the code...
function initialize() {
var myLatlng = new google.maps.LatLng(-26.322402, 31.142249);
var map = new google.maps.Map(document.getElementById('map-canvas'), {
zoom: 13,
center: myLatlng
});
var infowindow = new google.maps.InfoWindow();
var marker = new google.maps.Marker({
position: myLatlng,
map: map,
title: "We are here!"
});
var locations = [
[new google.maps.LatLng(-26.315402, 31.123924), 'Access Point 1', 'Custom text 1'],
[new google.maps.LatLng(-26.316700, 31.138043), 'Access Point 2', 'Custom text 2']
];
for (var i = 0; i < locations.length; i++) {
var marker = new google.maps.Marker({
position: locations[i][0],
map: map,
title: locations[i][1]
});
google.maps.event.addListener(marker, 'click', (function(marker, i) {
return function() {
infowindow.setContent(locations[i][2]);
infowindow.open(map, marker);
}
})(marker, i));
}
}
google.maps.event.addDomListener(window, 'load', initialize);
#map-canvas {
height: 200px;
}
<div id="map-canvas"></div>
<script src="https://maps.googleapis.com/maps/api/js"></script>

For your marker1 you can
var my_contentString1 = 'my text content 1... ' ;
var my_infowindow1 = new google.maps.InfoWindow({
content: my_contentString1
});
var accessPoint1 = new google.maps.LatLng(-26.315402,31.123924),
marker1 = new google.maps.Marker({
position: accessPoint1,
map: map,
title: "Access Point 1"
});
marker1.addListener('click', function() {
my_infowindow1.open(map, marker);
});
do the same for marker2

I ended up doing it this way which worked so well for me
<script type="text/javascript">
var locations = [
['ap7', -26.303139, 31.093508, 7],
['ap6', -26.322402, 31.142249, 6],
['ap5', -26.316700, 31.138043, 5],
['ap4', -26.315402, 31.123924, 4],
['ap3', -26.329244, 31.150478, 3],
['ap2', -26.309525, 31.134632, 2],
['ap1', -26.289923, 31.140195, 1]
];
var map = new google.maps.Map(document.getElementById('map'), {
zoom: 14,
center: new google.maps.LatLng(-26.309525, 31.134632),
mapTypeId: google.maps.MapTypeId.ROADMAP
});
var infowindow = new google.maps.InfoWindow();
var marker, i;
for (i = 0; i < locations.length; i++) {
marker = new google.maps.Marker({
position: new google.maps.LatLng(locations[i][1], locations[i][2]),
map: map
});
google.maps.event.addListener(marker, 'click', (function(marker, i) {
return function() {
infowindow.setContent(locations[i][0]);
infowindow.open(map, marker);
}
})(marker, i));
}
</script>

Auto Open Infowindow

I am loading multiple markers for 2 branches. I am not able to automatically open infowindow on load of the page?
var locations = [
['<strong>Info</strong><br /> Address', 40.004257, -105.253425, 2],
['<strong>Info</strong><br /> Address', 39.999326, -105.257662, 1]
];
var map = new google.maps.Map(document.getElementById('map'), {
zoom: 14,
center: new google.maps.LatLng(40.00, -105.24),
mapTypeId: google.maps.MapTypeId.ROADMAP
});
var infowindow = new google.maps.InfoWindow();
var marker, i;
for (i = 0; i < locations.length; i++) {
marker = new google.maps.Marker({
position: new google.maps.LatLng(locations[i][1], locations[i][2]),
icon: "images/favicon.png",
map: map
});
google.maps.event.addListener(marker, 'click', (function(marker, i) {
return function() {
infowindow.setContent(locations[i][0]);
infowindow.open(map, marker);
}
})(marker, i));
}
Anything wrong with the code? Is there a fix to auto open infowindow?

Here's what I've done to load the infoWindows when you load the page.
function initMap() {
var locations = [
['<strong>Info</strong><br> Address', 40.004257, -105.253425, 2],
['<strong>Info</strong><br> Address', 39.999326, -105.257662, 1]
];
var map = new google.maps.Map(document.getElementById('map'), {
zoom: 14,
center: new google.maps.LatLng(40.00, -105.24),
mapTypeId: google.maps.MapTypeId.ROADMAP
});
var marker, i;
for (i = 0; i < locations.length; i++) {
marker = new google.maps.Marker({
position: new google.maps.LatLng(locations[i][1], locations[i][2]),
map: map
});
var infowindow = new google.maps.InfoWindow({
content:locations[i][0]
});
infowindow.open(map, marker);
}
}

try adding
infowindow.open(map,marker);
after the for loop.
maybe this one could help.
Google maps open info window by default?

google map api V3 markers

I am having a problem with google maps, I cant put markers on some location. My idea was to find my location and to put marker on it, then to put markers on other locations but the markers on other locations are not showing on a map.
function success(position) {
var mapcanvas = document.createElement('div');
mapcanvas.id = 'mapcontainer';
mapcanvas.style.height = '550px';
mapcanvas.style.width = '960px';
document.querySelector('article').appendChild(mapcanvas);
var coords = new google.maps.LatLng(position.coords.latitude, position.coords.longitude);
var options = {
zoom: 15,
center: coords,
mapTypeControl: false,
navigationControlOptions: {
style: google.maps.NavigationControlStyle.SMALL
},
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("mapcontainer"), options);
var marker = new google.maps.Marker({
position: coords,
map: map,
title: "Vasa lokacija"
});
}
if (navigator.geolocation) {
navigator.geolocation.getCurrentPosition(success);
} else {
error('Geo Location is not supported');
}
var locations = [
['Banja Luka', 44.766666699999990000, 17.183333299999960000, 4],
['Tuzla', 44.532841000000000000, 18.670499999999947000, 5],
['Zenica', 44.203439200000000000, 17.907743200000027000, 3],

['Mostar', 43.333333300000000000, 17.799999999999954000, 1]
];
var infowindow = new google.maps.InfoWindow();
var marker, i;
for (i = 0; i < locations.length; i++) {
marker = new google.maps.Marker({
position: new google.maps.LatLng(locations[i][1], locations[i][2]),
map: map
});
google.maps.event.addListener(marker, 'click', (function (marker, i) {
return function () {
infowindow.setContent(locations[i][0]);
infowindow.open(map, marker);
}
})(marker, i));
}
}

The main problem with your function is that your marker adding loop is outside success function, so it never gets called. You also had an extra }at the end of your code. Here is a full solution jsfiddle
var map;
function success(position) {
var mapcanvas = document.createElement('div');
mapcanvas.id = 'mapcontainer';
mapcanvas.style.height = '550px';
mapcanvas.style.width = '960px';
document.querySelector('article').appendChild(mapcanvas);
var coords = new google.maps.LatLng(position.coords.latitude, position.coords.longitude);
var options = {
zoom: 15,
center: coords,
mapTypeControl: false,
navigationControlOptions: {
style: google.maps.NavigationControlStyle.SMALL
},
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById("mapcontainer"), options);
var marker = new google.maps.Marker({
position: coords,
map: map,
title: "Vasa lokacija"
});
if (navigator.geolocation) {
navigator.geolocation.getCurrentPosition(success);
} else {
error('Geo Location is not supported');
}
var locations = [
['Banja Luka', 44.766666699999990000, 17.183333299999960000, 4],
['Tuzla', 44.532841000000000000, 18.670499999999947000, 5],

['Mostar', 43.333333300000000000, 17.799999999999954000, 1]
];
var infowindow = new google.maps.InfoWindow();
var marker, i;
for (i = 0; i < locations.length; i++) {
marker = new google.maps.Marker({
position: new google.maps.LatLng(locations[i][1], locations[i][2]),
map: map
});
google.maps.event.addListener(marker, 'click', (function (marker, i) {
return function () {
infowindow.setContent(locations[i][0]);
infowindow.open(map, marker);
}
})(marker, i));
}
} //success fn ENDS
var position = {
coords: {
latitude: 44.766666699999990000,
longitude: 17.183333299999960000
}
};
success(position);

the main problem with your code is you are plotting the marker before the map is loaded because it is out side of your function success.try this:I have use static value for center you can change it as per your code.
$(document).ready(function () {
success(position);
});
var position = { // suppose this is your position
coords: {
latitude: 44.666666699999990000,
longitude: 17.183333299999960000
}
};
var map;
var marker, i;
var locations = [

];
function success(position) {
var mapcanvas = document.createElement('div');
mapcanvas.id = 'mapcontainer';
mapcanvas.style.height = '550px';
mapcanvas.style.width = '960px';
document.getElementById('article').appendChild(mapcanvas);

Calculate the center point of multiple Lat/Long

I am using Google Map to display multiple lat/long points.
But the Google map Javascript code has the code snippet to track the center of lat/long of the available lat/long.
<script type="text/javascript">
var locations = JSON.parse('<?php echo json_encode($data);?>'); //alert (locations);
var map = new google.maps.Map(document.getElementById('map'), {
zoom: 10,
center: new google.maps.LatLng(),
mapTypeId: google.maps.MapTypeId.ROADMAP
});
var infowindow = new google.maps.InfoWindow();
var marker, i;
for (i = 0; i < locations.length; i++) {
marker = new google.maps.Marker({
position: new google.maps.LatLng(locations[i][2], locations[i][3]),
map: map
});
google.maps.event.addListener(marker, 'click', (function(marker, i) {
return function() {
infowindow.setContent(locations[i][1]);
infowindow.open(map, marker);
}
})(marker, i));
}
</script>
In Above code the line
center: new google.maps.LatLng(),
needs a lat/long pair which could be the center point of multiple lat/long to be displayed.
How could that be done?

This works. See the documentation of Map.fitBounds and LatLngBounds for details:
<script type="text/javascript">
var locations = JSON.parse('<?php echo json_encode($data);?>');//alert (locations);
var map = new google.maps.Map(document.getElementById('map'), {
zoom: 10,
mapTypeId: google.maps.MapTypeId.ROADMAP
});
var infowindow = new google.maps.InfoWindow();
var marker, i;
var bounds = new google.maps.LatLngBounds();
for (i = 0; i < locations.length; i++) {
marker = new google.maps.Marker({
position: new google.maps.LatLng(locations[i][2],locations[i][3]),
map: map
});
bounds.extend(marker.getPosition());
google.maps.event.addListener(marker, 'click', (function(marker, i) {
return function() {
infowindow.setContent(locations[i][1]);
infowindow.open(map, marker);
}
})(marker, i));
}
map.fitBounds(bounds);
</script>
code snippet:
var locations = JSON.parse(
JSON.stringify([
['AAA', 'BBB', 42, -72],
['BBB', 'CCC', 42.1, -72.2]
])); //alert (locations);
var map = new google.maps.Map(document.getElementById('map'), {
zoom: 10,
mapTypeId: google.maps.MapTypeId.ROADMAP
});
var infowindow = new google.maps.InfoWindow();
var marker, i;
var bounds = new google.maps.LatLngBounds();
for (i = 0; i < locations.length; i++) {
marker = new google.maps.Marker({
position: new google.maps.LatLng(locations[i][2], locations[i][3]),
map: map
});
bounds.extend(marker.getPosition());
google.maps.event.addListener(marker, 'click', (function(marker, i) {
return function() {
infowindow.setContent(locations[i][1]);
infowindow.open(map, marker);
}
})(marker, i));
}
map.fitBounds(bounds);

You should get the bounds of your added markers with the function map.getBounds().
It returns an object on which you can get the center bound.getCenter().
