i have multiple google map instances on my website,now there are two different google map on a same page, what happens is the first one works and other doesn't now i know the logical issue let me show you my code first
<script>
function initMap() {
var myLatLng = {lat: 43.6222102, lng:-79.6694881};
var map = new google.maps.Map(document.getElementById('map'), {
zoom: 15,
center: myLatLng
});
var marker = new google.maps.Marker({
position: myLatLng,
map: map,
});
}
</script>
<script src="https://maps.googleapis.com/maps/api/js?key=my_key&callback=initMap"
async defer></script>
now as i defined a callback method it always initializes the method named initMap whereas what i want to do is there can be multiple google maps lets suppose initMap2 how can i load them without callback method?
To load the map without a callback, load the API synchronously/inline (without the async defer
), then call your initMap function on the load event.
( Note: FYI: Google changed all their examples to using asynchronous loading to improve the load times)
( Note2: Google has added a "sample" to their documentation describing synchronous loading )
code snippet:
function initMap() { var myLatLng = { lat: 43.6222102, lng: -79.6694881 }; var map = new google.maps.Map(document.getElementById('map'), { zoom: 15, center: myLatLng }); var marker = new google.maps.Marker({ position: myLatLng, map: map, }); } google.maps.event.addDomListener(window, 'load', initMap);
html, body, #map { height: 100%; width: 100%; margin: 0px; padding: 0px }
