I am facing problem related to Google map. First time when page load It show google map but If I re-lode page again google map not shown on page.Any body have Idea about this problem.
Thanks.
You Can do this way :
<div id="map" style="width:400px;height:400px;background:yellow"></div>
<script src="https://maps.googleapis.com/maps/api/js?key=AIzaSyBu-916DdpKAjTmJNIgngS6HL_kDIKU0aU&callback=myMap"></script>
<script>
function myMap() {
var mapOptions = {
center: new google.maps.LatLng(51.5, -0.12),
zoom: 10,
}
var map = new google.maps.Map(document.getElementById("map"), mapOptions);
}
We have this map:
https://www.google.com/maps/d/viewer?mid=z3MgxTVp8WWA.kbMeY2NPElcE
It can be exported into KMZ, by clicking "Download KML":
But when I try to embed this map on my own Google Maps, or even open in Google Earth, some placemarks are not displayed:
It there any way to fix this issue?
I see that problem with the KmlLayer renderer for the Google Maps Javascript API v3:
fiddle
code snippet:
var geocoder;
var map;
function initialize() {
var map = new google.maps.Map(
document.getElementById("map_canvas"), {
center: new google.maps.LatLng(37.4419, -122.1419),
zoom: 13,
mapTypeId: google.maps.MapTypeId.ROADMAP
});
var kmlLayer = new google.maps.KmlLayer({
url: "http://www.google.com/maps/d/kml?&mid=1JwCy1i6rn9ailO2MPxPj-XxX0EY&lid=z3MgxTVp8WWA.kUnMLigc_WOw",
map: map
});
google.maps.event.addListener(kmlLayer, 'status_changed', function() {
document.getElementById('status').innerHTML = kmlLayer.getStatus();
})
}
google.maps.event.addDomListener(window, "load", initialize);
html,
body,
#map_canvas {
height: 100%;
width: 100%;
margin: 0px;
padding: 0px
}
<script src="https://maps.googleapis.com/maps/api/js"></script>
<div id="status"></div>
<div id="map_canvas"></div>
Seems like an issue in Google's KML renderer. If I download your KML and render it with the third party library geoxml3 (disclaimer, I currently maintain that library), it displays OK.
redered with geoxml3 (but there is a performance hit due to the native rendering/lack of tile based rendering).
Note that I couldn't use the KMZ file directly, there seem to be character encoding issues with the zipped KML when rendered by geoxml3.
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') .
As part of a much bigger project, we're trying to get a Map on a site using Google's Map API v3. I have followed the simplest steps that Google has laid out, I've tried copying code outright from other working maps. But no matter what I do, all we get is a gray box and no map.
Using Firebug, I can see the information trying to populate the map, but it is simply not displaying. I've tried jquery, jquery libraries specifically made for google maps, nothing is working. I have been up and down the internet and all through google's api help files. Plus, the problem is not local as I've uploaded the file to multiple servers and tested it on multiple browsers and computers. Nothing is working.
At this point it's got to be something stupid that I'm overlooking. Here's my code.

This works for me. You simply have to set zoom parameter:
UPDATE (by #user2652379): You need to set BOTH zoom and center options. Just zoom does not work.

Another case is when map container is hidden at the moment you initialize the map. E.g. you are doing it inside bootstrap show.bs.modal event, instead of shown.bs.modal
I had the same issue and came across a lot of topics on stackoverflow but none of them had the working solution for me. I eventually found out it was caused to a line of css I had added.
All the elements in the map inherited a
overflow:hidden;
By adding the following line to my CSS it was fixed
#map * {
overflow:visible;
}
I would like to add a quick comment to this since I had the same problem with the zoom parameter set.
I found out that the problem was my theme's css. In my base theme I had the following CSS:
img, embed, object, video {
max-width: 100%;
max-height: 100%;
width: auto;
height: auto;
}
This messed up the rendering of the map and after I removed it, my map renders just fine.
Also beware of having an invalid latitude or longitude value for the map center or your markers. For example, this fiddle shows the Grey Map Of Death because the map center is at latitude 131.044 which is invalid (not from +90:-90).
function initMap() {
var uluru = {lat: 131.044, lng: -25.363};
var map = new google.maps.Map(document.getElementById('map'), {
zoom: 4,
center: uluru
});
var marker = new google.maps.Marker({
position: uluru,
map: map
});
}
In my case, I was working on a map with vue and a modal in the iview library; and during the first render it worked, but any other render displayed the grey screen of death. I fixed the issue by setting a timeout function to display the map after 50 ms to give the modal enough time to render and be visible.
//Time out is crucial for the map to load when opened with vue
setTimeout(() => {
this.showMap(id);
}, 50);
The above example was an earlier fix and a quick hack, i have realized all you need to do is wait for the next tick, on vue you can achieve this by
async mounted(){
await this.$nextTick()
this.showMap(id)
}
or if you are not comfortable with async await you can try the callback option
mounted(){
Vue.nextTick(function () {
this.showMap(id)
})
}
I had the same issue. i was using google maps in Jquery Accordion and when i expand the div the map only consisted a grayed area. I was able to solve this issue by triggering a click event on the specified accordion heading and setting the map container to visible.
Script:
<script type="text/javascript">
var map;
function initMap(lat, lng) {
var myCenter = new google.maps.LatLng(lat, lng);
var mapOptions = {
zoom: 8,
mapTypeId: google.maps.MapTypeId.ROADMAP,
center: myCenter
};
map = new google.maps.Map(document.getElementById('map'), mapOptions);
}
function ViewMap() {
var latlng = document.getElementById('<%=txt.ClientID%>').value.split(','); // This is where my latlng are placed: 25.12312,55.3212333
$("#showmap").show();
// Sorry for mixing up Jquery and javascript.
initMap(latlng[0], latlng[1]);
}
</script>
ASPX File/Html Markup:
<h3 id="lMap" onclick="ViewMap();"><i class="fa fa-map-o" onclick="ViewMap();"></i>Location Map</h3>
<div style="height:auto" id="showmap">
<div id="map" style="width: 850px; height: 550px; overflow: visible"></div>
</div>
I realise this is an old thread, but this may help someone in the future.
Struggled with this for hours, but after discovering that the Google Map is rendered with a grey box overlay if the map is rendered while not being visible, I used a bit of jQuery to make my application only instantiate and render the map if the map is visible, like such:
if ($("#myHomeMapHolder").is(":visible")) {
if (homemap == null) {
homemap = new google.maps.Map(document.getElementById("myHomeMapHolder"), myOptions);
google.maps.event.addListener(homemap, 'click', function (event) {
placeHomeMarker(event.latLng);
});
} else {
homemap.setCenter(myLatlng);
}
if (homemarker == null) {
homemarker = new google.maps.Marker({
position: myLatlng,
map: homemap,
title: "Home"
});
} else {
homemarker.setPosition(myLatlng);
}
}
And voila, my map is only rendered if the map holder is visible, so it never renders with a grey box.
For anyone wondering, myHomeMapHolder is a div which the map sits inside.
In my case, someone had dropped this little prize in some responsive.css file:
img {
max-width: 100% !important;
}
Removed that and all is fine now.
I had this issue with a site I'm working on too. We're doing some things to all <img> tags for responsiveness. This fix is working for us for the map:
img {max-width: initial !important;}
For those who might be stuck regardless of the nice solutions provided here, try setting the height and width of your container directly in the html markup instead of a stylesheet ie.
<div id="map-container" style="width: 100%; height: 300px;"></div>
happy mapping!
This may not be the case for everyone, but maybe it can help someone.
I was creating markers in my map from data attributes placed on the map element like this: data-1-lat="2" data-1-lon="3" data-text="foo". I was putting them in an array based on the order they were placed in the data attributes.
The problem is that IE and Edge (for some mad reason) invert the order of the data attributes in the HTML tag, therefore I wasn't able to correctly extract them from the data attributes.
None of the existing answers helped me because my problem was that Apollo was adding extra properties ("__typename" fields) to my MapOptions object.
In other words, the JSON looked like this:
mapOptions {"__typename":"MapOptions","center":{"__typename":"GeoCoordinates","lat":33.953056,"lng":-83.9925},"zoom":10}
Once I realized that those extra properties were problematic, this is how I solved it (using TypeScript):
function getCleanedMapOptions(mapOptionsGql: google.maps.MapOptions): google.maps.MapOptions {
const mapOptions = { ...mapOptionsGql };
const lat: number = mapOptions.center.lat as number;
const lng: number = mapOptions.center.lng as number;
const mapOptionsCleaned = {
center: new google.maps.LatLng({ lat, lng }),
zoom: mapOptions.zoom,
};
return mapOptionsCleaned;
}
export function createMap(mapOptions: google.maps.MapOptions): google.maps.Map {
const mapOptionsCleaned = getCleanedMapOptions(mapOptions);
const map = new google.maps.Map(document.getElementById('map') as HTMLElement, mapOptionsCleaned);
return map;
}
In my case (version is 3.30 when submitting this), it was because the div id MUST be "map"
<div id="map"></div>
...
document.getElementById("map")
It's exactly the example code of the maps API documentation found here:
Google maps API documentation
I have set up an map and it is showing.
Next step was showing the marker with geocoding..
But it's not working? Can anyone help me out?

An old question but as I recently hit the problem I thought I would share my solution. I found that something in the Javascript on the rest of my site was interfering with Google Maps. I was not getting any errors in Firebug or Chrome Console so I could not track down exactly what the conflict was.
I found that if I put the Google Map onto a blank ASPX page (i.e. no MasterPage with all of the Javascript and CSS from the rest of my site) that it worked fine.
The solution? I put the Google Map into an Iframe and now it works just fine. If you inspect the source of the Google Map example code, they use an Iframe too so there must be something to that.
you need to change the line new google.maps.LatLng(51.9645, 5.1965) to
var place = new google.maps.LatLng(51.9645, 5.1965);
and then use place as center in loOptions .
same as in marker also it really works :)
And import jquery as well
at the start of page.
