I have the following Javascript that includes both the standard Google Maps API initialize()
function and custom addMarker()
function. The map will load fine however the marker does not get added to the map.
<script type="text/javascript">
// Standard google maps function
function initialize() {
var myLatlng = new google.maps.LatLng(40.779502, -73.967857);
var myOptions = {
zoom: 12,
center: myLatlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
}
// Function for adding a marker to the page.
function addMarker(location) {
marker = new google.maps.Marker({
position: location,
map: map
});
}
// Testing the addMarker function
CentralPark = new google.maps.LatLng(37.7699298, -122.4469157);
addMarker(CentralPark);
</script>

<div id="map" style="width:100%;height:500px"></div>
<script>
function myMap() {
var myCenter = new google.maps.LatLng(51.508742,-0.120850);
var mapCanvas = document.getElementById("map");
var mapOptions = {center: myCenter, zoom: 5};
var map = new google.maps.Map(mapCanvas, mapOptions);
var marker = new google.maps.Marker({position:myCenter});
marker.setMap(map);
}

<script src="https://maps.googleapis.com/maps/api/js?key=AIzaSyBu-916DdpKAjTmJNIgngS6HL_kDIKU0aU&callback=myMap"></script>
function initialize() {
var location = new google.maps.LatLng(44.5403, -78.5463);
var mapCanvas = document.getElementById('map_canvas');
var map_options = {
center: location,
zoom: 15,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
var map = new google.maps.Map(map_canvas, map_options);
new google.maps.Marker({
position: location,
map: map
});
}
google.maps.event.addDomListener(window, 'load', initialize);
Below code works for me:
<script src="http://maps.googleapis.com/maps/api/js"></script>
<script>
var myCenter = new google.maps.LatLng(51.528308, -0.3817765);
function initialize() {
var mapProp = {
center:myCenter,
zoom:15,
mapTypeId:google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("googleMap"), mapProp);
var marker = new google.maps.Marker({
position: myCenter,
icon: {
url: '/images/marker.png',
size: new google.maps.Size(70, 86), //marker image size
origin: new google.maps.Point(0, 0), // marker origin
anchor: new google.maps.Point(35, 86) // X-axis value (35, half of marker width) and 86 is Y-axis value (height of the marker).
}
});
marker.setMap(map);
}
google.maps.event.addDomListener(window, 'load', initialize);
</script>
<body>
<div id="googleMap" style="width:500px;height:380px;"></div>
</body>
THis is other method
You can also use setCenter
method with add new marker
check below code
$('#my_map').gmap3({
action: 'setCenter',
map:{
options:{
zoom: 10
}
},
marker:{
values:
[
{latLng:[position.coords.latitude, position.coords.longitude], data:"Netherlands !"}
]
}
});
