In this example we have now added a few extra lines of code which allows us to display an info window when our map marker is clicked.


<div id="map_wrapper">
    <div id="map_canvas" class="mapping"></div>


#map_wrapper {
    height: 400px;

#map_canvas {
    width: 100%;
    height: 100%;

The JS

jQuery(function($) {
    // Asynchronously Load the map API 
    var script = document.createElement('script');
    script.src = "//maps.googleapis.com/maps/api/js?sensor=false&callback=initialize";

function initialize() {
    var map;
    // Set the latitude & longitude for our location (London Eye)
    var myLatlng = new google.maps.LatLng(51.503454,-0.119562);
    var mapOptions = {
        center: myLatlng, // Set our point as the centre location
        zoom: 14, // Set the zoom level
        mapTypeId: 'roadmap' // set the default map type
    // Display a map on the page
    map = new google.maps.Map(document.getElementById("map_canvas"), mapOptions);
    // Allow our satellite view have a tilted display (This only works for certain locations) 

    // Create our info window content   
    var infoWindowContent = '<div class="info_content">' +
        '<h3>London Eye</h3>' +
        '<p>The London Eye is a giant Ferris wheel situated on the banks of the River Thames. The entire structure is 135 metres (443 ft) tall and the wheel has a diameter of 120 metres (394 ft).</p>' +

    // Initialise the inforWindow
    var infoWindow = new google.maps.InfoWindow({
        content: infoWindowContent
    // Add a marker to the map based on our coordinates
    var marker = new google.maps.Marker({
        position: myLatlng,
        map: map,
        title: 'London Eye, London'

    // Display our info window when the marker is clicked
    google.maps.event.addListener(marker, 'click', function() {
        infoWindow.open(map, marker);
