I'm trying to migrate my application to latest version of Google map API and found that Google appends it's own items by default from Google Places directory to the map.
It does not look right together with my own records as it creates duplicate items on the map which can be placed in correctly.
Is there an option how to hide this local businesses or to control what is shown and what is not?
here is sample code:
<!DOCTYPE html>

mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById('map_canvas'),
myOptions);
}
google.maps.event.addDomListener(window, 'load', initialize);
</script>
</head>

As you can see on map, there are few tiny icons, which you can click on and information would appear in bubble. I need to hide this icons or at least disable on click event for this items.
Just a pointer - this seems possible with custom styled maps. If I'm not mistaken, the feature type you're looking for would be poi.business, whose visiblity you would turn off.
There's a wizard to help you build the options array.
You can remove it by adding the following code:
var styles = [
{
featureType: "poi",
stylers: [
{ visibility: "off" }
]
}
];
var styledMap = new google.maps.StyledMapType(styles,{name: "Styled Map"});

I have a KMZ file that i load into my google maps application via link using javascript. The file works perfectly in Google Earth. The problem is in my application when i click in one of the many elements (areas): the returned description data is always from only one of the elements, not displaying the actual clicked, correct, element. This is what i've tried:
Check if the click event in the map is correct by placing a marker in the clicked position, it is correct.
Convert the data into KML using Google Earth, place it into my google drive as public, and using a direct download link from google drive in my application. It displayed the data but the error continued.
Created the most basic/blank application using just the layer to make sure anything else in my other application is interfering. Also didn't work.
The file is in this website: https://www.voanaboa.pt/codigo-drone named as "Regulamento RPA_ver_5.0.kmz”
Here's the only file that creates a basic application using the kmz file, i've removed my API key for privacy.

Most (but not all) of your placemarks have the same ID "ID_00000"). If I change that to be unique, the polygon's descriptions become unique:
example with unique ids
Per the KML reference, that doesn't have to be unique (it is a "stanard XML ID", but I am guessing the rendering code is assuming it is.

This question already has an answer here:
Google Maps Api V3 - Styling countries or cities
(1 answer)
Closed 5 years ago.
I want to show in my website only certain places using GoogleMap.It shouldn't show any small places.Only major places should be visilble in map.What is procedure to obtain this?
Set your lat/lon to the location of a post office (or other city indicator).
Then, use the zoom property to fix to the level you want to encompass.
See: https://developers.google.com/maps/documentation/javascript/examples/marker-simple
Here is the code form the example:
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="initial-scale=1.0, user-scalable=no">
<meta charset="utf-8">
<title>Simple markers</title>

#map {

/* Optional: Makes the sample page fill the window. */

height: 100%;
margin: 0;
padding: 0;
}
</style>

<div id="map"></div>
<script>
function initMap() {
var myLatLng = {lat: -25.363, lng: 131.044};
var map = new google.maps.Map(document.getElementById('map'), {
zoom: 4,
center: myLatLng
});
var marker = new google.maps.Marker({
position: myLatLng,
map: map,
title: 'Hello World!'
});
}
</script>
<script async defer

</script>

Try that script at map.zoom = 16. Should be close to city view. London I think.
You can also set map bounds, but that is a lot harder. You would need to find your location, then plot geometry around that area, define the points, and then, zoom all points into view.
All of this is possible, but you showed me no code, so I'm not showing any back.
Hope you found something useful,
I'd like to localise the map generated by Gmaps4rails, so I can show place names in the users desired language. Google documents how to do this here: https://developers.google.com/maps/documentation/javascript/examples/map-language
I'm using a fairly standard (and currently functional) implementation of Gmaps4rails, which you can see here.
handler = Gmaps.build('Google');
handler.buildMap({
provider: { styles: mapStyle },
internal: {id: 'map'}
}, function(){
markers = handler.addMarkers(<%=raw #hash.to_json %>);
handler.bounds.extendWith(markers);
handler.fitMapToBounds();
});
Rendering to the html...
<div class="map-container">
<div id="map"></div>
</div>
I just need to find out where to define the language code. I've tried adding it as an option to the provider, with no joy (e.g. provider: { styles: mapStyle, language: 'zh-TW' }).
I've scoured the documentation (and source), but can't seem to find any info on this. Any help would be appreciated!
You have to indicate the language in the script.
For example in the Maps API v3 Now Speaks Your Language:
<script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false&language=pt-BR">
You can find the list of languages here.
Here is the code sample:
<!DOCTYPE html>
<html>
<head>
<title>Localizing the Map</title>
<meta name="viewport" content="initial-scale=1.0, user-scalable=no">
<meta charset="utf-8">
<style>
html, body {
height: 100%;
margin: 0;
padding: 0;
}
#map {
height: 100%;
}
</style>
</head>
<body>
<div id="map"></div>
<script>
// This example displays a map with the language and region set
// to Japan. These settings are specified in the HTML script element
// when loading the Google Maps JavaScript API.
// Setting the language shows the map in the language of your choice.
// Setting the region biases the geocoding results to that region.
function initMap() {
var map = new google.maps.Map(document.getElementById('map'), {
zoom: 8,
center: {lat: 35.717, lng: 139.731}
});
}
</script>
<script src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&callback=initMap&language=ja®ion=JP"
async defer>
</script>
</body>
</html>
As you can see in this code line, key=YOUR_API_KEY&callback=initMap&language=ja®ion=JP, language is set to jp = Japanese.
Also check their working sample with a dynamic language setting.
Hope this helps!
I have a google map api page that does not return the correct coordinates from the mouse event in firefox when the map div is not at the top left (0,0) of the browser window. If I put any css padding or margin on the map div, the mouseevent origin in google maps still starts from the top left of the browser window and not the map div. The mouseevent works correctly in IE & Chrome returning the correct lat/lng but not Firefox. Anyone have any suggestions to correct?
I created a very simple example at http://jsfiddle.net/fNPvf/15426/ that shows the coordinates as the mouse is moved over the map. You can see at the top left of the map image, the coordinates should be 0,0 but Firefox showing 50,50. The infowindow shows the correct lat/lng of the map center and you can see the difference in coordinates (50 pixel shift to top left) when you move the mouse to that point.

Solution:
Add parameter v=3 once calling the google maps api. The fiddle provided by user4974882 is calling 3.exp - doesn't work.
Works:
<script src="https://maps.googleapis.com/maps/api/js?v=3"></script>
Live example
Doesn't work correctly:
<script src="https://maps.googleapis.com/maps/api/js?v=3.exp"></script>
<script src="https://maps.googleapis.com/maps/api/js"></script>
Live example
(both fiddles from user4974882)
Background:
The problem occured with Firefox Version 39. The Mozilla-team implemented some new functionality regarding offsetX/Y (https bugzilla.mozilla.org/show_bug.cgi?id=69787). Unfortunately the Google Maps API already somehow plays around with that (https code.google.com/p/gmaps-api-issues/issues/detail?id=8278) and so - once FF39 was rolled out - the problem popped up.
Problem with latest release of FF v39. Worked previously in v38.0.5.
I can confirm that the following is bugged, given a map with a fixed size and a 64px margin, "Hello World!" will only appear when you place the mouse pointer at -64,-64 relative to the marker. It appears that inside Maps, the pointer position is offset by the x/y of the map element relative to the top left corner of Firefox' client area

When creating a marker use the option {optimized:false}. It solves the issue in firefox 39.0.

As stated - this bug crept in with FF 39.
In your example, replace the v=3.exp parameter with just v=3
So it would be

I want to show location in Google map using JavaScript, but when I zoom out, it shows multiple maps! Also, the map is not fixed in the browser window.
How can I fixate it to the window and force it to show just one map?

Edit :
I have uploaded my page screen shot here :
one : is when my page is loaded.
two : is when I zoom out and resize the window.
three : is when I move map to scroll it.
as you see, in two I have three map ! and in three map didn't fix to its div!
Edit2:
I upload my code!
Your question is not really clear. Could you please provide further explanation of the issue?
Resizing the map on div change
From API reference:
Developers should trigger this event on the map when the div changes
size: google.maps.event.trigger(map, 'resize') .
All you have to do is trigger this event when your window resizes e.g. window.onresize
Adding listener
window.addEventListener('resize', function(){
google.maps.event.trigger(map,'resize');
});
Displaying the map div
Put this in the <head> of your document.
<style type="text/css">
html { height: 100% }
body { height: 100%; margin: 0; padding: 0 }
#my_location{ height: 100% }
</style>
From what I can tell, you are concerned that at the highest zoom levels three copies of the map are shown? This is standard to Google Maps and basically all webmaps. If you don't want that, you could investigate making a custom map with Kartograph.
If you are trying to stop zooming, change to the following code:
var myOptions = {
zoom: 16,
center: new google.maps.LatLng(lat,lng),
mapTypeId: google.maps.MapTypeId.ROAD ,
scrollwheel: false,
disableDoubleClickZoom: true,
minZoom: 1
};
Other than that, I'm not sure what you are asking.
