Good afternoon,
I'm trying to implement a Google Maps inside my SobiPro entries (SobiPro is a directory component for Joomla) but it's not working properly. My map is showing some parts with a grey color and after searching and finding a lot of solutions, I need you to ask for help because any of the other solutions worked.
I have tried everything and it's still not working.
Here is the URL, in the third label you will find my map "Direccion" is called: http://bdebeauty.es/component/sobipro/268
What can I do to solve this problem?
Edit with more code:
<style>
#map-canvas {
margin: 0px;
padding: 0px;
}
</style>
<script>
function initialize2() {
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', initialize2);
</script>
<div id="map-canvas" style="width:450px;height:300px;"></div>
Thanks in advance.
I think what you will need is something like google.maps.event.trigger(map, 'resize');
as it is said in the documentation,
Developers should trigger this event on the map when the div changes size: google.maps.event.trigger(map, 'resize') .

I created google map with multiple markers to my website with "Google My Maps" tool and my code looks like this:
<iframe src="https://www.google.com/maps/d/u/0/embed?mid=1PdcME79x-maD5xuiVEi4C777aL4" width="640" height="480"></iframe>
It was really quick and simple without any code writting but what I don't like is the header bar which is showing the name and share button. Can I somehow hide this bar? Thank you.
You can get the link to the KML from that "MyMap":
http://www.google.com/maps/d/kml?mid=1PdcME79x-maD5xuiVEi4C777aL4
And use that to populate a KmlLayer in a Google Maps Javascript API v3 map:
var kmlLayer = new google.maps.KmlLayer({
url: "http://www.google.com/maps/d/kml?mid=1PdcME79x-maD5xuiVEi4C777aL4",
map:map
});

I am having difficulties trying to add an image as a ground overlay to a google map that I am creating. In all of the help files that I have seen, the image has been passed to the ground overlay function as a url. Is it possible to have an image that is stored on my machine passed in, rather than an online image?
Here's the code I have for the map & overlay:
function initialize() {
var mapOptions = {
center: {lat: 45.3469, lng: -75.7594},
zoom: 10,
disableDefaultUI: true,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);
var imageBounds = new google.maps.LatLngBounds(
new google.maps.LatLng(45.2118075, -75.4455767),
new google.maps.LatLng(45.2043559, -75.4545309));
var campusOverlay = new google.maps.GroundOverlay('Campus.JPG', imageBounds);
campusOverlay.setMap(map);
}
I am looking to add the 'Campus.jpg' image that I created to the map. I have also tried passing in the entire path with all its directories and still nothing appears on the map. If there is no way of passing an image like this, is there a way to put the image online and use it that way?
Thanks
Pass in a full url to the image as the first parameter for GroundOverlay and make sure that your bounds are correct. This can be kind of tricky. Your overlay should cover a northern lat and southern lat/east and
west longitude, so you essentially have some sort of rectangular area.
Here is a quick example. Sure you will get the idea.
var overlay;
function initialize() {
var center = new google.maps.LatLng(45.3469, -75.7594);
var imageBounds = new google.maps.LatLngBounds(
new google.maps.LatLng(45.2, -76.1),
new google.maps.LatLng(45.5, -75.38)
);
var mapOptions = {
zoom: 10,
center: center,
disableDefaultUI: true
};
var map = new google.maps.Map(document.getElementById('map-canvas'),
mapOptions);
overlay = new google.maps.GroundOverlay(
'https://upload.wikimedia.org/wikipedia/commons/e/ee/Dowarian%2C_Neelam_Valley%2C_AJK_Pakistan.JPG',
imageBounds);
overlay.setMap(map);
}
google.maps.event.addDomListener(window, 'load', initialize);
html, body, #map-canvas {
height: 100%;
margin: 0px;
padding: 0px
}
<script src="https://maps.googleapis.com/maps/api/js?v=3.exp&signed_in=true"></script>
<div id="map-canvas"></div>
Hope that helps.
*Hi there, i am new to the whole Google map api environment so please do guide me along.
What i am trying to achieve below is to extract data from either a XML file or a JSON file and plot the locations onto Google map. I am also trying to add a info window whereby it will show different information for each location. I understand that to have a info window, i would have to create a over lay. But the question is how do i actually tag multiple info-window to their markers ?
All markers are displayed well on the map, but the problem is when I click to see info window - info window is always displayed on the same marker. What's the problem?
This is what i have came up with so far and i would greatly appreciate if anyone is able to spot the issue.

Use this instead of marker, when opening infowindow.
google.maps.event.addListener(marker, "mouseover", function() {
infowindow.open(map, this);
});
I'm having a heck of a time trying to get a basic Google Map to show up. I've been on Stack Overflow for hours and haven't had any success so far. The closest I've gotten is the map loads 1/4 of a square, the top left quarter. But then if you try to drag, zoom, etc it just turns grey like the rest of the map. On a few occasions, with the same code, the map will load fully but only after a long time (not sure exactly how long, but > 5 minutes).
In my template I have
<div id="map" style="width: 500px; height: 400px;"></div>
And then in my backbone view
$.getScript('http://maps.google.com/maps/api/js?sensor=false&callback=gMapsCallback')
window.gMapsCallback = function(){
var myLatlng = new google.maps.LatLng(-34.397, 150.644);
var mapOptions = {
zoom: 8,
center: myLatlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("map"),
mapOptions);
}
Any ideas what might be happening? I am also open to any suggestions on a superior way to load a google map into a backbone view.
Ok, turns out there were a number of issues, including embedding a map in a Bootstrap tab, not including a callback, defining the div height and width, setting a small delay to load the map, and setting css attributes for the map. Oi. My final solution turned out to be:
In the template
<script src='http://maps.google.com/maps/api/js?sensor=false&callback=gMapsCallback'></script>
<div id="map" style="width: 500px; height: 400px;"></div>
In the stylesheet
#map img {
max-width: none;
}
#map label {
width: auto; display:inline;
}
In the Backbone View
setTimeout(function(){
var myLatlng = new google.maps.LatLng(53.1, -2.44);
var mapOptions = {
zoom: 8,
center: myLatlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("map"),
mapOptions);
// Create marker
var marker = new google.maps.Marker({
map: map,
position: new google.maps.LatLng(53.1, -2.44),
title: 'The armpit of Cheshire'
});
// Add circle overlay and bind to marker
var circle = new google.maps.Circle({
map: map,
radius: 10000, // metres
fillColor: '#AA0000'
});
circle.bindTo('center', marker, 'position');
google.maps.event.trigger(map, "resize");
map.setZoom( map.getZoom() );
}, 100);
Painful. Notice that when I call the gmaps script I had to include the callback even though I never use it. Without it, it didn't work fully. No clue why.
I'm trying to create my own map using google map.
I want to create a list showing all existing markers on the map. When user clicks on one button/link from the list, the corresponding marker will be centered and its infoWindow will be displayed, i.e. the same effects as the user clicks on the marker.
I have tried a number of solutions, but I could get none of them working. Can anyone please offer me a simple solution for this? Thanks in advance!
My existing code is as follows,
google.maps.event.addDomListener(window, 'load', function() {
var map = new google.maps.Map(document.getElementById('map'), {
center: new google.maps.LatLng(19.642588,151.171875),
mapTypeId: google.maps.MapTypeId.ROADMAP,
mapTypeControl: false
});
var infoWindow = new google.maps.InfoWindow;
var onMarkerClick1 = function() {
var marker = this;
infoWindow.setContent('content of infowindow');
infoWindow.open(map, marker);
};
var marker1 = new google.maps.Marker({
map: map,
position: new google.maps.LatLng(19.642588,151.171875),
});
google.maps.event.addListener(marker1, 'click', onMarkerClick1);
this won't center the map on it, but will move so the whole balloon is visible
http://econym.org.uk/gmap/example_map2.htm
as simple as i can get it. yes, please use GMarker etc.
don't forget this in the header <script src="http://maps.google.com/maps?...
you'll need html that includes
<div id="map" style="width: 550px; height: 450px"></div>
<div id="side_bar">Marker One<br /></div>
and then javascript
var map = new GMap2(document.getElementById("map"));
map.setCenter(new GLatLng(19.642588, 151.171875), 8);
var point = new GLatLng(19.642588, 151.171875);
var marker = new GMarker(point);
GEvent.addListener(marker, "click", function () {
marker.openInfoWindowHtml("this marker has been clicked");
});
function myclick(i) {
GEvent.trigger(marker, "click");
}
map.addOverlay(marker);
