Calculate the center point of multiple Lat/Long - javascript

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().

How to customize two google maps with javascript on one page?

I need two Google maps on one page. Both of maps should have multiple pins on it. One map show hotels, another one restaurants. I tried to add pins and location names with javascript but all pins shows one location name.
This is html code for maps:
Hotels map:
<div id="map-accommodation" class="interactive-map" style="width: 100%; height: 500px;"></div>
Restaurants map:
<div id="map-food" class="interactive-map" style="width: 100%; height: 500px;"></div>
This is script code for maps:
Hotels map:
var locations = [
['Sheraton', 41.646230, 41.649160, 1],
['Hilton', 41.627184, 41.5991094, 2],
['Radisson', 41.6296321, 41.6002718, 3]
];
var map = new google.maps.Map(document.getElementById('map-accommodation'), {
zoom: 12,
center: new google.maps.LatLng(41.616756, 41.636745),
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));
}
Restaurants map:
var locations = [
['360 Cloud bar', 41.6472564, 41.6251435, 1],
['Sky bar', 41.6479619, 41.6275468, 2],
['Sky tower', 41.6479619, 41.6275468, 3]
];
var map = new google.maps.Map(document.getElementById('map-food'), {
zoom: 12,
center: new google.maps.LatLng(41.616756, 41.636745),
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));
}
So these maps show different locations, hotels map shows me only hotels, restaurants map shows me only restaurant pins, but all of them have one name - "sky tower".
Can you explain why and how can I fix it?
Use a unique array for each map (i.e. hotels, restaurants) and if you want each map to have its own InfoWindow (both maps currently share one InfoWindow), make a unique one of those as well.
var hotels = [
['Sheraton', 41.646230, 41.649160, 1],
['Hilton', 41.627184, 41.5991094, 2],
['Radisson', 41.6296321, 41.6002718, 3]
];
var map = new google.maps.Map(document.getElementById('map-accommodation'), {
zoom: 12,
center: new google.maps.LatLng(41.616756, 41.636745),
mapTypeId: google.maps.MapTypeId.ROADMAP
});
var infowindow = new google.maps.InfoWindow();
var marker, i;
for (i = 0; i < hotels.length; i++) {
marker = new google.maps.Marker({
position: new google.maps.LatLng(hotels[i][1], hotels[i][2]),
map: map
});
google.maps.event.addListener(marker, 'click', (function(marker, i) {
return function() {
infowindow.setContent(hotels[i][0]);
infowindow.open(map, marker);
}
})(marker, i));
}
var restaurants = [
['360 Cloud bar', 41.6472564, 41.6251435, 1],
['Sky bar', 41.6479619, 41.6275468, 2],
['Sky tower', 41.6479619, 41.6275468, 3]
];
var map = new google.maps.Map(document.getElementById('map-food'), {
zoom: 12,
center: new google.maps.LatLng(41.616756, 41.636745),
mapTypeId: google.maps.MapTypeId.ROADMAP
});
var infowindow = new google.maps.InfoWindow();
var marker, i;
for (i = 0; i < restaurants.length; i++) {
marker = new google.maps.Marker({
position: new google.maps.LatLng(restaurants[i][1], restaurants[i][2]),
map: map
});
google.maps.event.addListener(marker, 'click', (function(marker, i) {
return function() {
infowindow.setContent(restaurants[i][0]);
infowindow.open(map, marker);
}
})(marker, i));
}

When I click a marker on Google map it should open multiple markers, but the marker that has been clicked should also appear

I have written code for Google Maps API where when I click a marker multiple markers should appear, but the marker that has been clicked should also appear. Means the page should not refresh. Please help me. Here is my code where if you click on the marker multiple markers will appear, but the marker disappears.

Ok, this is how I fixed it:
function initMap() {
var uluru = {
lat: 25.2138,
lng: 75.8648
};
var map = new google.maps.Map(document.getElementById('map'), {
zoom: 8,

});
var marker = new google.maps.Marker({
position: uluru,
map: map
});
var infowindow = new google.maps.InfoWindow({
content: 'Hello World!',
map: map
});
marker.addListener('click', function() {
clicktoOpenMAp();
});
marker.addListener('mouseover', function() {
infowindow.open(map, this);
});
marker.addListener('mouseout', function() {
infowindow.close();
});
function clicktoOpenMAp() {
// var map;
var bounds = new google.maps.LatLngBounds();
var mapOptions = {
mapTypeId: 'roadmap'
};
// map = new google.maps.Map(document.getElementById("map"), mapOptions);
map.mapTypeId = "roadmap";
map.setTilt(50);
var markers = [
['chittorgarh', 24.8887, 74.6269],
['morak', 24.7265, 75.9739],
['mangrol', 25.3362, 76.5112]
];
for (i = 0; i < markers.length; i++) {
var position = new google.maps.LatLng(markers[i][1], markers[i][2]);
bounds.extend(position);
marker = new google.maps.Marker({
position: position,
map: map,
title: markers[i][0]
});
google.maps.event.addListener(marker, 'click', (function(marker, i) {
return function() {
infoWindow.setContent(infoWindowContent[i][0]);
infoWindow.open(map, marker);
}
})(marker, i));
map.fitBounds(bounds);
}
var boundsListener = google.maps.event.addListener((map), 'bounds_changed', function(event) {
this.setZoom(8);
google.maps.event.removeListener(boundsListener);
});
}
}
You were "creating" another map everytime you clicked in the marker (I commented the line so you know), then you need to put the Function clicktoOpenMap inside initmap.
Note: I also added async defer to the script where you call the api
<script
src="https://maps.googleapis.com/maps/api/js?key='YourGoogleApiBecauseicantsharemine'&callback=initMap" async defer></script>
You can hide the markers with
markers[i].setMap(null);
and to erase them
var markers = [];

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?

animated gif in array in google map

I am trying to use optimize:false parameter in my code to use animated gif as a mouseover:
var icon1 = "circle.png";
var icon2 = "circlered.gif";
var markers = [];
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,
visible: false,
icon: icon1
});
google.maps.event.addListener(marker, 'mouseover', (function(marker, i) {
return function(evt) {
infowindow.setContent(locations[i][0] + "<br>" + marker.getPosition().toUrlValue(6));
infowindow.open(map, marker);
marker.setIcon(icon2);
}
})(marker, i));
markers.push(marker); // save all markers
google.maps.event.addListener(marker, 'mouseout', (function(marker) {
return function(evt) {
infowindow.close();
marker.setIcon(icon1);
}
})(marker));
when I use for example:
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,
visible: false,
icon: icon2, //here I purposely changed it to animated gif first
optimize: false
});
I have no problems.
but when I try to use the same here:
google.maps.event.addListener(marker, 'mouseover', (function(marker, i) {
return function(evt) {
infowindow.setContent(locations[i][0] + "<br>" + marker.getPosition().toUrlValue(6));
infowindow.open(map, marker);
marker.setIcon(icon2);
optimize:false;// here is the wrong code obviously
}
})(marker, i));
I get the image disappearing not animating
Please suggest solution

as you can see the code in "Fir AZE" draws a layer.
then later it(the drawn layer) is supposed to be shown on click , the example provided initially at this link www.visualguide.ca/example shows that.
when I was asking about the solution for the animated marker I thought that I had problem with optimize :false - because all their lines of code were working ok.
as I have tried to implement solution provided below it worked! but I lost my ability to show/hide layers on click.sorry if this was not clear initially
my intial code was:

};
// Set map
map = new google.maps.Map(document.getElementById('map-canvas'),
mapOptions);
it was changed to
function initialize() {
var map = new google.maps.Map(
document.getElementById("map-canvas"), {
center: new google.maps.LatLng(40.222869, 47.602673),
zoom: 13,
mapTypeId: google.maps.MapTypeId.TERRAIN
});
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][1], locations[i][2]),
map: map,
optimized: false,
visible: false,
icon: icon1
});
bounds.extend(marker.getPosition())
//....
}
map.fitBounds(bounds);
}
I have compared line by line to locate this, and am stumbled.
One option is to create the marker with {optimized: false}:
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,
optimized: false,
icon: icon1
});
google.maps.event.addListener(marker, 'mouseover', (function(marker, i) {
return function(evt) {
infowindow.setContent(locations[i][0] + "<br>" + marker.getPosition().toUrlValue(6));
infowindow.open(map, marker);
marker.setIcon(icon2);
}
})(marker, i));
markers.push(marker); // save all markers
google.maps.event.addListener(marker, 'mouseout', (function(marker) {
return function(evt) {
infowindow.close();
marker.setIcon(icon1);
}
})(marker));
}

var map;
var infowindow = new google.maps.InfoWindow();

somehow I have managed(with the help of geocoder and Alex - thanks
//announce my variables
var icon1 = "circle.png";
var icon2 = "circlered.gif";
var markers = [];
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,
optimized:false, // <-- required for animated gif
visible: false,
icon: icon1
});
I also managed to have my layers appearing on click

Place multiple php vars as lat/long in Google Maps

This is what I have... PHP pulls down 10 pairs of lat/long from an API url which I have managed to get working okay but I cannot seem to plot them on a map with multiple markers labelled 1-10.
My php code:
<?php
// Loading Domus API
$url_search = 'http://url/site/go/api/search';
$xml_search = #simplexml_load_file($url_search) or die ("no file loaded") ;
//Displaying latitude and longutude
$house = json_encode($house);
}; ?>
JavaScript bit:
var locations = "<?php foreach($xml_search->property as $house) { echo $lat = $house->address->latitude , $long = $house->address->longitude;}; ?>";
var map = new google.maps.Map(document.getElementById('map'), {
zoom: 10,
center: new google.maps.LatLng(37.0625,-95.677068),
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));
}
Which is then needs to be displayed in here
<div id="map" style="width: 500px; height: 400px"></div>
But I just get a blank page, of course.
Okay, I've managed to figure it out.
Here is my php code in the head part
<?php
// Loading Domus API
$url_search = 'http://url/site/go/api/search';
$xml_search = #simplexml_load_file($url_search) or die ("no file loaded") ;?>
Then I have my javascript
// Load property ID followed by Lat and Long for each house (total of 10)
var locations = [<?php foreach($xml_search->property as $house) {
echo '['.$house->id. ',' .$house->address->latitude. ',' .$house->address->longitude.'],';
} ?>];
var map = new google.maps.Map(document.getElementById('map'), {
zoom: 15,
center: new google.maps.LatLng(0, 0),
mapTypeId: google.maps.MapTypeId.ROADMAP
});
var infowindow = new google.maps.InfoWindow();
var marker, i;
var markers = new Array();
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
});
markers.push(marker);
google.maps.event.addListener(marker, 'click', (function(marker, i) {
return function() {
infowindow.setContent(locations[i][0]);
infowindow.open(map, marker);
}
})(marker, i));
}
function AutoCenter() {
// Create a new viewpoint bound
var bounds = new google.maps.LatLngBounds();
// Go through each...
$.each(markers, function (index, marker) {
bounds.extend(marker.position);
});
// Fit these bounds to the map
map.fitBounds(bounds);
}
AutoCenter();
Works beautifully, now just need to set up labelled markers and I am good to go.
