How to Display Multiple Google Maps per page with API V3

Solution 1:

Here is how I have been able to generate multiple maps on the same page using Google Map API V3. Kindly note that this is an off the cuff code that addresses the issue above.

The HTML bit

<div id="map_canvas" style="width:700px; height:500px; margin-left:80px;"></div>
<div id="map_canvas2" style="width:700px; height:500px; margin-left:80px;"></div>

Javascript for map initialization

<script type="text/javascript">
var map, map2;

function initialize(condition) {
    // create the maps
    var myOptions = {
        zoom: 14,
        center: new google.maps.LatLng(0.0, 0.0),
        mapTypeId: google.maps.MapTypeId.ROADMAP
    }
    map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);

    map2 = new google.maps.Map(document.getElementById("map_canvas2"), myOptions);
}
</script> 

Solution 2:

I have just finished adding Google Maps to my company's CMS offering. My code allows for more than one map in a page.

Notes:

• I use jQuery
• I put the address in the content and then parse it out to dynamically generate the map
• I include a Marker and an InfoWindow in my map

HTML:

<div class="block maps first">
    <div class="content">
        <div class="map_canvas">
            <div class="infotext">
                <div class="location">Middle East Bakery & Grocery</div>
                <div class="address">327 5th St</div>
                <div class="city">West Palm Beach</div>
                <div class="state">FL</div>
                <div class="zip">33401-3995</div>
                <div class="country">USA</div>
                <div class="phone">(561) 659-4050</div>
                <div class="zoom">14</div>
            </div>
        </div>
    </div>
</div>
<div class="block maps last">
    <div class="content">
        <div class="map_canvas">
            <div class="infotext">
                <div class="location">Global Design, Inc</div>
                <div class="address">3434 SW Ash Pl</div>
                <div class="city">Palm City</div>
                <div class="state">FL</div>
                <div class="zip">34990</div>
                <div class="country">USA</div>
                <div class="phone"></div>
                <div class="zoom">17</div>
            </div>
        </div>
    </div>
</div>

Code:

$(document).ready(function() {
    $maps = $('.block.maps .content .map_canvas');
    $maps.each(function(index, Element) {
        $infotext = $(Element).children('.infotext');

        var myOptions = {
            'zoom': parseInt($infotext.children('.zoom').text()),
            'mapTypeId': google.maps.MapTypeId.ROADMAP
        };
        var map;
        var geocoder;
        var marker;
        var infowindow;
        var address = $infotext.children('.address').text() + ', '
                + $infotext.children('.city').text() + ', '
                + $infotext.children('.state').text() + ' '
                + $infotext.children('.zip').text() + ', '
                + $infotext.children('.country').text()
        ;
        var content = '<strong>' + $infotext.children('.location').text() + '</strong><br />'
                + $infotext.children('.address').text() + '<br />'
                + $infotext.children('.city').text() + ', '
                + $infotext.children('.state').text() + ' '
                + $infotext.children('.zip').text()
        ;
        if (0 < $infotext.children('.phone').text().length) {
            content += '<br />' + $infotext.children('.phone').text();
        }

        geocoder = new google.maps.Geocoder();
        geocoder.geocode({'address': address}, function(results, status) {
            if (status == google.maps.GeocoderStatus.OK) {
                myOptions.center = results[0].geometry.location;
                map = new google.maps.Map(Element, myOptions);
                marker = new google.maps.Marker({
                    map: map,
                    position: results[0].geometry.location,
                    title: $infotext.children('.location').text()
                });
                infowindow = new google.maps.InfoWindow({'content': content});
                google.maps.event.addListener(map, 'tilesloaded', function(event) {
                    infowindow.open(map, marker);
                });
                google.maps.event.addListener(marker, 'click', function() {
                    infowindow.open(map, marker);
                });
            } else {
                alert('The address could not be found for the following reason: ' + status);
            }
        });
    });
});

Solution 3:

OP wanted two specific maps, but if you'd like to have a dynamic number of maps on one page (for instance a list of retailer locations) you need to go another route. The standard implementation of Google maps API defines the map as a global variable, this won't work with a dynamic number of maps. Here's my code to solve this without global variables:

function mapAddress(mapElement, address) {
var geocoder = new google.maps.Geocoder();

geocoder.geocode({ 'address': address }, function (results, status) {
    if (status == google.maps.GeocoderStatus.OK) {
        var mapOptions = {
            zoom: 14,
            center: results[0].geometry.location,
            disableDefaultUI: true
        };
        var map = new google.maps.Map(document.getElementById(mapElement), mapOptions);
        var marker = new google.maps.Marker({
            map: map,
            position: results[0].geometry.location
        });
    } else {
        alert("Geocode was not successful for the following reason: " + status);
    }
});
}

Just pass the ID and address of each map to the function to plot the map and mark the address.
