I am trying to put info windows in for a Google Maps page. I am using an API to call data and also using the markerclusterer.js plugin. I've seen how to do it with with a JSON object or if the markers are within the JavaScript document but I don't understand how to apply it to calling from another API.
What am I doing wrong? Can you please explain?

});
This is not valid:
google.maps.event.addListener(markers, 'click', function() {
console.log("hello world")
infowindow.open(map, Markers);
});
An event listener doesn't work on an array, needs to be added to each marker (that it applies to) individually.
You can use function closure to associate the infowindow to the marker (below example uses a createMarker function) and make the infowindow global. Note that you don't have to use function closure there are other ways to solve the issue. Below example puts the entry.file_name into the infowindow.

Hej. Google maps turns up grey in the browser, but can see the markers and the google logo in the bottom right corner.
Have tried the resize function, but still won't work.I am using bootstraps col.
I can see it works here, but it doesn't.
Thanks for the help.

I have an HTML page with a list of buttons representing locations. When any button is clicked, I want a Google Map to appear with that location. Should the map open on a new HTML page? (because the map should take up the full page), or is it possible to display the map on the same page?
EDIT - OK, I want to open it in another HTML file. I have an external JS file which has the following Map code:
function initialize(lat, lng) {
var mapOptions = {
center: {lat: parseFloat(lat), lng: parseFloat(lng)},
zoom: 8,
mapTypeId : google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("map-canvas"), mapOptions);
}
google.maps.event.addDomListener(window, 'load', initialize(-34.397, 150.644));
My external HTML file is given below:
<html>
<head>
<style type="text/css">
html, body, #map-canvas { height: 100%; margin: 0; padding: 0;}
</style>
<script type="text/javascript" src="http://maps.google.com/maps/api/js?v=3&sensor=false"></script>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
<script src="script.js" ></script>
</head>
<body>
<div id="map-canvas"></div>
</body>
</html>
But its not working. The external JS file cannot locate "map-canvas", it seems. Can anyone tell me how to fix this? (script.js is the external JS file)
I worked around your question try this :
<!DOCTYPE html>
<html>
<head>

<script>
var render_map = function( lat, lng, title ) {
var mapCanvas = document.getElementById('map-canvas');
// options
var args = {

center : new google.maps.LatLng(lat, lng),
mapTypeId : google.maps.MapTypeId.ROADMAP
};
// create map
var map = new google.maps.Map( mapCanvas, args);
// create marker
var marker = new google.maps.Marker({
position: args.center,
map: map,
title: title
});
toggleMap();
}
var toggleMap = function(){
if ($('body').hasClass('-show-map')) {
mapHide();
} else {
mapShow();
};
}
$('.map-trigger').on('click', function(event) {
event.preventDefault();
var lat = $(this).data('lat');
var lng = $(this).data('lng');
render_map(lat, lng);
});

I'm developing the Google Map web application using Google Map 3 library, I want to add the HTML panel when I click on button on infowindow. The panel position always beside the infowindow. Can everyone help me or give me an example to resolve it?
It looks like this:
For example I have some code, could I display the div #panel on the right of the div #content?

I'm trying to customize google map but I have a small problem.
Here is the css code:
#map-canvas {
width: 100%;
height: 500px;
}
and the js code:
<script src="https://maps.googleapis.com/maps/api/js?v=3.exp&sensor=false"></script>
<script>
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);
</script>
And this is how I initialize the map in html. This example actually works.
<div id="map-canvas"></div>
But when I trying to put my map into some div e.g:
<div>
<div id="map-canvas"></div>
</div>
It doesn't work. How to fix that ?

Please put this into example.html and try to run. Nothing happens for me.

Your parent div should have height and width defined.
<body>
<div style="height:100%; width:100%;">
<div id="map-canvas"></div>
</div>
</body>
Try This.

Nothing seems wrong in your code ,it works fine just seprated css.I have checked and tested.

I have made a Google Version 3 Geocoder , I want to be able to pick up the coordinates of the marker when it is dragged or clicked. Below is my code:

I have tried to use the following code to do this but it does not seem to work.
// Javascript//
google.maps.event.addListener(marker, 'dragend', function(evt){
document.getElementById('current').innerHTML = '<p>Marker dropped: Current Lat: ' + evt.latLng.lat().toFixed(3) + ' Current Lng: ' + evt.latLng.lng().toFixed(3) + '</p>';
});
google.maps.event.addListener(marker, 'dragstart', function(evt){
document.getElementById('current').innerHTML = '<p>Currently dragging marker...</p>';
});
map.setCenter(marker.position);
marker.setMap(map);
//HTML//
<div id='map_canvas'></div>
<div id="current">Nothing yet...</div>
That code works just fine if you put it in the correct place:
http://www.geocodezip.com/BlakeLoizides_geocode.html
(inside the callback routine, the marker is local to it)
