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.

Clustering markers with infowindow in googlemaps v3 api

I cant get the ClustererMarker to work. I want markers to cluster when they are close to each other and I have found:
var mcOptions = {gridSize: 50, maxZoom: 15};
var mc = new MarkerClusterer(map, markers, mcOptions);
But I cant get them to work with my code, either all markers disappear or only one is visible (not in the correct way). I hope someone can help me with my problem.
for (var i = 0; i < locations.length; i++) {
var marker = new google.maps.Marker({
position: new google.maps.LatLng(locations[i][1], locations[i][2]),
map: map
});
google.maps.event.addListener(marker, 'mouseover', (function (marker, i) {
return function () {
infowindow.setContent(locations[i][0]);
infowindow.open(map, marker);
}
})(marker, i));
}

var gmarkers = [];
for (var i = 0; i < locations.length; i++) {
var marker = new google.maps.Marker({
position: new google.maps.LatLng(locations[i][1], locations[i][2]),
map: map
});
google.maps.event.addListener(marker, 'mouseover', (function (marker, i) {
return function () {
infowindow.setContent(locations[i][0]);
infowindow.open(map, marker);
}
})(marker, i));
gmarkers.push(marker);
}
var markerCluster = new MarkerClusterer(map, gmarkers);

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?

Change Google Maps marker icon when clicking on other

I have created a Google Maps Multiple locations page,
using Advanced Custom Fields Google Map field.
I have managed to make the marker icon change when clicked on, but I want it to be changed back when clicking on other icons.
here is an example of the code:
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: iconBase + 'Stock%20Index%20Up.png'
});
google.maps.event.addListener(marker, 'click', (function(marker, i) {
return function() {
infowindow.setContent(locations[i][0], locations[i][6]);
infowindow.open(map, marker);
marker.setIcon("https://cdn3.iconfinder.com/data/icons/musthave/24/Stock%20Index%20Down.png");
}
})(marker, i));
Better look of the working code here:
http://jsfiddle.net/gargiguy/s8vgxp3g

What duncan said: What you want to do is add all your markers to an array. In your click event handler, loop over that array, updating each marker's icon. Then finally set the icon for just the marker that's been clicked.
google.maps.event.addListener(marker, 'click', (function (marker, i) {
return function () {
infowindow.setContent(locations[i][0], locations[i][6]);
infowindow.open(map, marker);
for (var j = 0; j < markers.length; j++) {
markers[j].setIcon("https://cdn3.iconfinder.com/data/icons/musthave/24/Stock%20Index%20Up.png");
}
marker.setIcon("https://cdn3.iconfinder.com/data/icons/musthave/24/Stock%20Index%20Down.png");
};

Since it sounds like you only need to change the previous icon back to the original, I wouldn't recommend looping through every marker. In a map with a lot of markers, this could become quite heavy.
Instead, I would store the active marker in a variable on the click event, and just update that one when it changes.
var marker;
var activeMarker;
var iconDefault = iconBase + 'Stock%20Index%20Up.png';
var iconSelected = 'https://cdn3.iconfinder.com/data/icons/musthave/24/Stock%20Index%20Down.png';
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: iconDefault
});
google.maps.event.addListener(marker, 'click', (function(marker, i) {
return function() {
infowindow.setContent(locations[i][0], locations[i][6]);
infowindow.open(map, marker);
// check to see if activeMarker is set
// if so, set the icon back to the default
activeMarker && activeMarker.setIcon(iconDefault);
// set the icon for the clicked marker
marker.setIcon(iconSelected);
// update the value of activeMarker
activeMarker = marker;
}
})(marker, i));
}

You can do same like below:
var prevMarker = "";
var markers = [];
var image = { url: "your_png.png",
scaledSize: new google.maps.Size(38, 40) // If you want to resize it.
};
For creating marker,
var marker = createMarker(coordinate, map, image, id);
// coordinate = {lat:float value,long:float value} and 'map' your map
function createMarker(lat, long, map, image, marker_id) {
var coordinates = {lat: lat, lng: long};
var marker = new google.maps.Marker({
position: coordinates,
icon: image,
id: "marker_" + marker_id,
map: map
});
return marker;
}
For marker action you can use.
marker.addListener('click', function() {
console.log(this.id);
if(prevMarker !== "") {
prevMarker.setIcon({
url: "your_image.png",
scaledSize: new google.maps.Size(38, 40)
});
}
prevMarker = this;
this.setIcon({
url: "your_image.png",
scaledSize: new google.maps.Size(48, 50)
});
map.panTo(this.getPosition());
});
loop marker code for all markers available.

Google map info window on wrong locations

I'm following this code for Multiple Markers in Google map, my problem is once I put my data in the map their info window are all in the wrong coordinates, they seem scrambled. I am using US as my center. So here is the code below:
var locations = [
['Russ Martin</br>Montana',43.299428,-74.217933],
['Carey Fischer</br>New York',46.879682,-110.362566],
['Brandon Born</br>Connecticut',40.714353,-74.005973],
['Joe Tocyloski</br>Pennysylvania',41.603221,-73.087749]
];
var us = new google.maps.LatLng(42.746632,-75.770041);
var map = new google.maps.Map(document.getElementById('map'), {
zoom: 4,
center: us,
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({
/*icon:{
strokeColor:'green',
scale:3
},*/
position: new google.maps.LatLng(locations[i][1], locations[i][2]),
map: map,
animation:google.maps.Animation.DROP
});
google.maps.event.addListener(marker, 'mouseover', (function(marker, i) {
return function() {
infowindow.setContent(locations[i][0]);
infowindow.open(map, marker);
}
})(marker, i));
google.maps.event.addListener(marker, 'mouseout', (function(marker, i) {
return function() {
infowindow.setContent(locations[i][0]);
infowindow.close(map, marker);
}
})(marker, i));
console.log(locations);
}
Any help would be appreciated.
Fiddle

below statement may
this will surely help u
return function() {
infowindow.setContent(locations[i][0]);
infowindow.open(map, this);
}
