I have looked every where and am starting to go crazy. I know I am close, but can't get it.
I have my html:
<div id="glasgow-map" class="collapse">
<div class="map">
<div id="map-canvas" style="width:100%; height:350px;"></div>
</div>
</div><!--end collapse-->
my JS is:
function initialize() {
var myLatlng = new google.maps.LatLng(55.860949,-4.244938);
var mapOptions = {
zoom: 16,
center: myLatlng
}
var map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);
var marker = new google.maps.Marker({
position: myLatlng,
map: map,
title: 'Taylor Hopkinson Associates'
});
}
google.maps.event.addDomListener(window, 'load', initialize);
$('#glasgow-map').on('shown.bs.collapse', function () {
google.maps.event.trigger(map, "resize");
map.setCenter(center);
})
From all the other info I have seen I know I need the (map, "resize) but I am getting this error in the console:
Uncaught ReferenceError: map is not defined
Any help would be fantastic. It's been a long day!!
Thanks for your Help #kamlesh, I think you are right, but this is the way I finally managed to get it to work, and also for multiple maps - if anyone needs help with that, it's below.
I stripped the google.maps.event.addDomListener(window, 'load', initialize); and added the initialize to the .collapse button for when it is clicked. This way there is no need for the resize.
function initialize() {
var myLatlng = new google.maps.LatLng(55.860949,-4.244938);
var myLatlng2 = new google.maps.LatLng(51.510142,-0.143314);
var myLatlng3 = new google.maps.LatLng(51.4004236,0.0172711);
var mapOptions = {
zoom: 16,
center: myLatlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
var mapOptions2 = {
zoom: 16,
center: myLatlng2,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
var mapOptions3 = {
zoom: 16,
center: myLatlng3,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
var map = new google.maps.Map(document.getElementById('map-canvas1'), mapOptions);
var map2 = new google.maps.Map(document.getElementById('map-canvas2'), mapOptions2);
var map3 = new google.maps.Map(document.getElementById('map-canvas3'), mapOptions3);
var marker = new google.maps.Marker({
position: myLatlng,
map: map,
title: 'Taylor Hopkinson Associates'
});
var marker2 = new google.maps.Marker({
position: myLatlng2,
map: map2,
title: 'Taylor Hopkinson Associates'
});
var marker3 = new google.maps.Marker({
position: myLatlng3,
map: map3,
title: 'Taylor Hopkinson Associates'
});
}
$('#glasgow-map').on('shown.bs.collapse', function (e) {
initialize();
})
$('#london-map').on('shown.bs.collapse', function (e) {
initialize();
})
$('#bromley-map').on('shown.bs.collapse', function (e) {
initialize();
})
Perhaps there is a way of streamlining this code, but it certainly works for me.

I am working on google maps api on web
This is my code
function initialize() {
var myLatlng = new google.maps.LatLng(-25.363882,131.044922);
var mapOptions = {
zoom: 4,
center: myLatlng
}
var map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);
var marker = new google.maps.Marker({
position: myLatlng,
map: map,
title: 'Hello World!'
});
}
google.maps.event.addDomListener(window, 'load', initialize);
Just the map is shown but the marker is not, why please?
I have a second question please. What is the best action the user expect to click (or do) what they want to add a marker on the map?
Thanks
Maybe you used the ID wrong.
JS:
function initialize() {
var myLatlng = new google.maps.LatLng(-25.363882, 131.044922);
var mapOptions = {
zoom: 4,
center: myLatlng
}
var map = new google.maps.Map(document.getElementById('map_canvas'), mapOptions);
var marker = new google.maps.Marker({
position: myLatlng,
map: map,
title: 'Hello World!'
});
}
google.maps.event.addDomListener(window, 'load', initialize);

I'm creating a map using the Javascript API, and I'm having some trouble getting the markers to show up.
I've followed this tutorial to create the map, which works well:
https://developers.google.com/maps/tutorials/fundamentals/adding-a-google-map
I've then followed this tutorial to add the marker, but it's not loading:
https://developers.google.com/maps/documentation/javascript/examples/marker-simple
Here's my code now:
<script>
function initialize() {
var map_canvas = document.getElementById('map_canvas');
var map_options = {
center: new google.maps.LatLng(43.643296, -79.408475),
zoom: 15,
mapTypeId: google.maps.MapTypeId.ROADMAP }
var map = new google.maps.Map(map_canvas, map_options, marker);
var marker = new google.maps.Marker({
position: myLatlng,
map: map,
title:"Hello World!" });
}
google.maps.event.addDomListener(window, 'load', initialize);
</script>
This line
var map = new google.maps.Map(map_canvas, map_options, marker);
is wrong. mapconstructor has only two arguments. It should be
var map = new google.maps.Map(map_canvas, map_options);
And myLatlng is not defined. So, you can change your code to:
function initialize() {
myLatlng = new google.maps.LatLng(43.643296, -79.408475);
var map_canvas = document.getElementById('map');
var map_options = {
center: myLatlng,
zoom: 15,
mapTypeId: google.maps.MapTypeId.ROADMAP }
var map = new google.maps.Map(map_canvas, map_options);
var marker = new google.maps.Marker({
position: myLatlng,
map: map,
title:"Hello World!" });
}

I am using the below javascript code to show map and marker.The marker is loading while map load,but i want to load the marker if the button named "Add marker" is clicked.The marker should points to the current location.How to do this here.
js.
<meta name="viewport" content="initial-scale=1.0, user-scalable=no" />
<script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script>
<script type="text/javascript">
var geocoder = new google.maps.Geocoder();
function updateMarkerStatus(str) {
document.getElementById('markerStatus').innerHTML = str;
}
function updateMarkerPosition(latLng) {
document.getElementById('info').innerHTML = [
latLng.lat(),
latLng.lng()
].join(', ');
}
function updateMarkerAddress(str) {
document.getElementById('address').innerHTML = str;
}
function initialize() {
var latLng = new google.maps.LatLng(-29.3456, 151.4346);
var map = new google.maps.Map(document.getElementById('mapCanvas'), {
zoom: 8,
center: latLng,
mapTypeId: google.maps.MapTypeId.ROADMAP
});
var marker = new google.maps.Marker({
position: latLng,
title: 'Marker',
map: map,
draggable: true
});
};
google.maps.event.addDomListener(window, 'load', initialize);
</script>
html
<div id="mapCanvas"></div>
Thanks
please try this. hope it help.
1. make map as global variable.
2. initialize map
3. add marker on button click event.
<script type="text/javascript">
var map;
function initialize() {
map = new google.maps.Map(document.getElementById('mapCanvas'), {
zoom: 8,
center: latLng,
mapTypeId: google.maps.MapTypeId.ROADMAP
});
};
jQuery("$addmarker").click(function(){
var marker = new google.maps.Marker({
position: new google.maps.LatLng(23.72, 72.100),
title: 'Marker',
map: map,
draggable: true
});
})
</script>
Here is my complete sample code.
<script type="text/javascript">
var map;
function initialize()
{
var mapOptions = {
center: new google.maps.LatLng('23.11', '71.00'),
zoom: 2,
scrollwheel: false,
disableDefaultUI: false,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById("map_canvas"),mapOptions);
}
function addMarker()
{
marker = new google.maps.Marker({
position: new google.maps.LatLng(23.72, 72.100),
map: map,
});
}
</script>
</HEAD>
<BODY onload="initialize();">
<div id="map_canvas" style="width:700px; height:500px;"></div>
<input type="button" id="addMarker" value="addMarker" onclick="addMarker();"/>
</BODY>
</HTML>
data is array which contains lat and lng
function addMarker(data) {
var marker = new google.maps.Marker({
position: new google.maps.LatLng(data.lat, data.lng),
map: map
});
You need to put the part:
var marker = new google.maps.Marker({
[...]
});
inside a onclick event listener.
The jQuery way to do this with a button element:
$('button').on('click', function() {
var marker = new google.maps.Marker({
[...]
});
});
You have to think about making the variables map and latLng global.
var map; // Declare map as global.
function initialize() {
var latLng = new google.maps.LatLng(-29.3456, 151.4346);
map = new google.maps.Map(document.getElementById('mapCanvas'), {
zoom: 8,
center: latLng,
mapTypeId: google.maps.MapTypeId.ROADMAP
});
}
// Call addMarker on click of the button.
function addMarker(){
var latLng = new google.maps.LatLng(-29.3456, 151.4346); // Put lat long as desired.
var marker = new google.maps.Marker({
position: latLng,
title: 'Marker',
map: map,
draggable: true
});
}
I do not know what is wrong with my code for displaying a map marker for my address. I have looked on the google development site as well as blogs and stack overflow posts but seem to not be able to understand it or for some reason can not effectively implement it into my code. I want a marker to display for an address on a map, that when clicked will take them to a URL for google maps of that location.
My CSS:
var myLatlng = new google.maps.LatLng(-25.363882,131.044922);
var mapOptions = {
zoom: 4,
center: myLatlng,
mapTypeId: google.maps.MapTypeId.ROADMAP,
}
var map = new google.maps.Map(document.getElementById("map-canvas"), mapOptions);
var marker = new google.maps.Marker({
position: myLatlng,
title:"Hello World!"
});
// To add the marker to the map, call setMap();
marker.setMap(map);
My HTML:
<div style="height: 277px; width: 964px; z-index; 1;">
<div id="map-canvas" style="margin: 0; padding: 0; height: 100%;"></div>
</div>
try this:
function initialize() {
var myLatlng = new google.maps.LatLng(-25.363882, 131.044922);
var mapOptions = {
zoom: 4,
center: myLatlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
var map = new google.maps.Map(document.getElementById("map-canvas"), mapOptions);
var marker = new google.maps.Marker({
position: myLatlng,
title: "Hello World!"
});
marker.setMap(map);
}
google.maps.event.addDomListener(window, 'load', initialize);
EDIT:
How do I link the marker to a URL?
var infowindow = new google.maps.InfoWindow({
content: "<a href='http://www.google.com'>Visit Google!</a> "
});
google.maps.event.addListener(marker, 'click', function () {
infowindow.open(map, marker);
});
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>
You have added the add marker method call outside the function and that causes it to execute before the initialize method which will be called when google maps script loads and thus the marker is not added because map is not initialized
Do as below....
Create separate method TestMarker and call it from initialize.
<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);
TestMarker();
}
// Function for adding a marker to the page.
function addMarker(location) {
marker = new google.maps.Marker({
position: location,
map: map
});
}
// Testing the addMarker function
function TestMarker() {
CentralPark = new google.maps.LatLng(37.7699298, -122.4469157);
addMarker(CentralPark);
}
</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);
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 !"}
]
}
});
<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>
<script src="https://maps.googleapis.com/maps/api/js?key=AIzaSyBu-916DdpKAjTmJNIgngS6HL_kDIKU0aU&callback=myMap"></script>
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>
