<div class="col-12">
<div class="alert alert-success"><h2>Google Maps Multiple Marker(Pins) Javascript</h2>
</div>
<div id="map_wrapper_div">
<div id="map_tuts"></div>
</div>
</div>
</div>
</body>
</html>
Implement css for Markers on Google Map
In this step, you need to implement some css for google map styling. Now put the css code on head section :
<style>
.container{
padding: 2%;
text-align: center;
}
#map_wrapper_div {
height: 400px;
}
#map_tuts {
width: 100%;
height: 100%;
}
</style>
Implement javascript code for show Multiple Markers on Google Map
Finally, you need to implement javascript code for creating a map on web pages and adding and showing multiple markers ( pins ) on google maps. Now add the code on script tag after the closing of body tag.
<script>
jQuery(function($) {
// Asynchronously Load the map API
var script = document.createElement('script');
script.src = "https://maps.googleapis.com/maps/api/js?sensor=false&callback=initialize";
document.body.appendChild(script);
});
function initialize() {
var map;
var bounds = new google.maps.LatLngBounds();
var mapOptions = {
mapTypeId: 'roadmap'
};
// Display a map on the page
map = new google.maps.Map(document.getElementById("map_tuts"), mapOptions);
map.setTilt(45);
// Multiple Markers
var markers = [
['Mumbai', 19.0760,72.8777],
['Pune', 18.5204,73.8567],
['Bhopal ', 23.2599,77.4126],
['Agra', 27.1767,78.0081],
['Delhi', 28.7041,77.1025],
];
// Info Window Content
var infoWindowContent = [
['<div class="info_content">' +
'<h3>Mumbai</h3>' +
'<p>Lorem Ipsum Lorem Ipsum Lorem Ipsum Lorem Ipsum Lorem Ipsum</p>' +'</div>'],
['<div class="info_content">' +
'<h3>Pune</h3>' +
'<p>Lorem Ipsum Lorem Ipsum Lorem Ipsum Lorem Ipsum Lorem Ipsum</p>' +'</div>'],
['<div class="info_content">' +
'<h3>Bhopal</h3>' +
'<p>Lorem Ipsum Lorem Ipsum Lorem Ipsum Lorem Ipsum Lorem Ipsum</p>' +'</div>'],
['<div class="info_content">' +
'<h3>Agra</h3>' +
'<p>Lorem Ipsum Lorem Ipsum Lorem Ipsum Lorem Ipsum Lorem Ipsum</p>' +'</div>'],
['<div class="info_content">' +
'<h3>Delhi</h3>' +
'<p>Lorem Ipsum Lorem Ipsum Lorem Ipsum Lorem Ipsum Lorem Ipsum</p>' +'</div>'],
];
// Display multiple markers on a map
var infoWindow = new google.maps.InfoWindow(), marker, i;
// Loop through our array of markers & place each one on the map
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]
});
// Each marker to have an info window
google.maps.event.addListener(marker, 'click', (function(marker, i) {
return function() {
infoWindow.setContent(infoWindowContent[i][0]);
infoWindow.open(map, marker);
}
})(marker, i));
// Automatically center the map fitting all markers on the screen
map.fitBounds(bounds);
}
// Override our map zoom level once our fitBounds function runs (Make sure it only runs once)
var boundsListener = google.maps.event.addListener((map), 'bounds_changed', function(event) {
this.setZoom(5);
google.maps.event.removeListener(boundsListener);
});
}
</script>
