I am trying to make tabs using js to have more data on the site.
Please view: http://dev.ateo.dk/officelab-konferencecenter/
The two tabs at the top ("Billeder" and "kort") are made using js.
If i go into the tap called "kort", the google maps will not load completely - however if i right-click and choose "Inspect Element (Q)" using firefox, the map suddenly loads.
Also, the map is not centered. on the specific location - the location is in the top left corner.
You may notice a blank square below the tab div. This is the exact same code as used within the js tab. If i comment out the in js tab, the square which is blank, will work perfectly. So it somehow seems that the js tab combined with the js google maps are not working. Can this be the case, and if so, how is it fixed?
Below i am showing the code which will init the google maps and the taps on the page:
if($('body.single-konferencested').length > 0)
{
tabs();
}
if($('body.single-konferencested').length > 0)
{
$(document).ready(function() {
function initialize() {
var myLatlng = new google.maps.LatLng(place_lat,place_lng);
var mapOptions = {
zoom: 9,
center: myLatlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
var map = new google.maps.Map(document.getElementById('gmap'), mapOptions);
var marker = new google.maps.Marker({
position: myLatlng,
map: map,
clickable : true
});
var pinIcon = new google.maps.MarkerImage(
"http://dev.ateo.dk/wp-content/themes/ateo/img/pin_marker.png",
null, /* size is determined at runtime */
null, /* origin is 0,0 */
null, /* anchor is bottom center of the scaled image */
new google.maps.Size(24, 40)
);
marker.setIcon(pinIcon);
var content_string = '<div id="gmap_info">'+
'<div id="siteNotice">'+
'</div>'+
'<h3 id="firstHeading" class="firstHeading">'+place_title+'</h3>'+
'<div id="bodyContent">'+
'<p>'+place_address+'<br />'+place_city_zip+'</div>'+
'</div>';
var infowindow = new google.maps.InfoWindow({
content: content_string
});
google.maps.event.addListener(marker, 'click', function() {
infowindow.open(map, marker);
});
}
google.maps.event.addDomListener(window, 'load', initialize);
});
}
This following is the html showing the DOM for the "Kort" tab:
<div class="tabContent" id="kort" style="padding: 5px 10px;">
<h2>Kort</h2>
<div id="gmap" style="width: 600px; height: 400px;"></div>
<h2>test</h2>
</div>
Best regards

If the div in which the map is going to live is not visible on page load the map will not load correctly. You should fire a resize once the div has come into view.
google.maps.event.trigger(map, 'resize');
You should bind this to the first click of the map tab.
It looks like the map is commented out of the second tab currently. If you could uncomment it it would be easier to help you more specifically!
EDIT:
to bind the function once, try this:
var tab = jQuery('ul#tabs li')[1]
jQuery(tab).one('click', function(){
google.maps.event.trigger(map, 'resize');
});
In order for the resize to work you will need access to the map variable from your init function.
It would also be easier to select the correct tab if you drop a class on it. That would be more reliable then getting the 2nd li in the tabs ul.
EDIT 2:
try adding the click function in your initialize code. Something similar to the following
var mapOptions = {
zoom: 9,
center: myLatlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
var map = new google.maps.Map(document.getElementById('gmap'), mapOptions);
//add the code here, after the map variable has been instantiated
var tab = jQuery('ul#tabs li')[1]
jQuery(tab).one('click', function(){
google.maps.event.trigger(map, 'resize');
//fire a center event after the resize, this is also useful
// if bound to a window resize
map.setCenter(myLatlng)
});
//end of new code
var marker = new google.maps.Marker({
position: myLatlng,
map: map,
clickable : true
});
It can be solved easily by re-initialize the Google Map on Tab click.
$('#kort').click(function(e) {
initialize();
resetMap(map);
});

I'm trying to append a button to a page that when clicked will display my google map in a new page. I have a button that when clicked either gives an error or gives a blank page.
My code:
$('.content--body__wrapper').append('<button id="show-map" />')
$('.content--body__wrapper').append(`<script>
document.getElementById("show-map").addEventListener("click", function(){
var center = {lat: -25.363, lng: 131.044};
var map = new google.maps.Map(document.getElementById('map'), {
zoom: 4,
center: center
});
var marker = new google.maps.Marker({
position: center,
map: map,
});
})
</script>`);
$('.content--body__wrapper').append(`<script src="https://maps.googleapis.com/maps/api/js?key=AIzaSyBcwtM8EBe7BE1NyPbU5SDYVYoBBtbtpTI&libraries=drawing" asyncdefer></script>`);
Error Code:
Edit: I took the callback out of the script source and I still don't get a page to load but I do have a lot less errors.
$('.content--body__wrapper').append('<script src="https://maps.googleapis.com/maps/api/js?key=AIzaSyBcwtM8EBe7BE1NyPbU5SDYVYoBBtbtpTI&libraries=drawing&callback=initMap" async defer></script>');
In this line you say : when the API is loaded run the function called InitMap.
The problem is that this function is not definied in your js.
So remove this callback to use the documentReady event or remove documentReadyListener and create a function name initMap
In Google Maps, I would like to be able to keep the center of the map on a marker on my location when I'm zooming in or out. It's something that Ingress does, it doesn't matter where you double tap (or double click) or where you pinch, the map remains centered on your marker. So it's possible...
The best I came up with for now is :
google.maps.event.addListener(mymap, 'zoom_changed', function() {
mymap.setCenter({lat: myLoc.lat, lng: myLoc.lon});
})
But it's far from perfect, it just re-center the map after the user already zoomed...
Thanks a lot !
[EDIT] absolutely nothing helps in the API ref... Or elsewhere I'm blind and missed it !
Purely using Javascript
First you disable scroll zoom function by default of google map by scrollwheel=false,
Next create custom scroll zoom function by capture mouse event and set zoom level for google map
Check my sample code: Fiddle URL: https://jsfiddle.net/vh3gqop0/17/
var map, i = 12;
function initialize() {
var myLatlng = new google.maps.LatLng(46.769603, 23.589957);
var mapOptions = {
center: myLatlng,
zoom: i,
scrollwheel: false,
disableDoubleClickZoom: true,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById("map_canvas"),
mapOptions);
var marker = new google.maps.Marker({
position: myLatlng,
map: map,
title: 'Any Title'
});
}
google.maps.event.addDomListener(window, 'load', initialize);
$( document ).ready(function() {
$('#map_canvas').on("wheel", function(evt){
// console.log(evt.originalEvent.deltaY);
if(evt.originalEvent.deltaY > 0){
map.setZoom(++i);
}else {
map.setZoom(--i);
}
});
});
#map_canvas{
height:400px;
width:100%;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.0.3/jquery.min.js"></script>

I have no idea why you tagged this question as both Javascript and Android. On Android you need to wrap your MapView inside another view and detect Double Tap motion inside onInterceptTouchEvent which you can override if your class can override FrameLayout for example. Then return true to prevent the map from handling this event and you handle it instead.
For full code please see my answer here: https://stackoverflow.com/a/30118649/764897
Unfortunately Google Maps Api does not provide this behaviour.
The following example doesn't require jQuery and supports double-click and mouse scrolling, but you can add more events if you want.
View in Codepen
Disable:
Double-clickin
Scrolling
Panning
Add dblclick and zoom_changed events on the map and a mousewheel event on the canvas.
I have commented the code, hopefully this works for your case. Keep in mind that you need to normalize mousewheel speed for all browsers and devices. Hammer.js is a good library for that.
var map, zoom;
function initialize() {
// The white house!
var myLatLng = new google.maps.LatLng(38.8977, -77.0365);
// Default zoom level
zoom = 17;
// Keep a reference for evens
var $map = document.getElementById("map");
// Disable scrolling + double-click + dragging
map = new google.maps.Map($map, {
zoom: zoom,
center: myLatLng,
mapTypeId: google.maps.MapTypeId.ROADMAP,
scrollwheel: false,
disableDoubleClickZoom: true,
//draggable: false
});
var marker = new google.maps.Marker({
position: myLatLng,
map: map
});
// EVENTS
// Double Click: event zoom by 1
map.addListener('dblclick', function(e) {
zoomHandler(e.latLng, 1);
});
// Zoom changed: update current zoom level
map.addListener('zoom_changed', function(e) {
// Using a timeout because `getZoom()` does not return a promise.
setTimeout(function() {
zoom = map.getZoom();
}, 50);
});
// Dom event: On mousewheel
$map.addEventListener('mousewheel', wheelEvent, true);
}
// Mouse Scrolling event
function wheelEvent(event) {
if (event.deltaY > 1)
zoomHandler(event, -1);
else
zoomHandler(event, 1);
}
// Zoom in/out
function zoomHandler(event, zoomin) {
zoom += zoomin;
map.setZoom(zoom);
}
google.maps.event.addDomListener(window, 'load', initialize);
#map {
width: 100%;
height: 240px;
}
<div id="map"></div>
<script src="https://maps.googleapis.com/maps/api/js?key=AIzaSyC9d3jaUX6Qdr0Uzvq6fQXVmZ1PBuHEVAQ"></script>
You should try the center_changed event with panTo function.
google.maps.event.addListener(mymap, 'center_changed', function() {
mymap.panTo({lat: myLoc.lat, lng: myLoc.lon});
})
You can see an example about it here and documentation about panTo function here.
Becareful, it should mess up all the draggable thing.
I put Google Map inside a div, and made a slideToggle onto the div.
the Google Map doesn't display correctly.
Once the div expanded, it doesn't look right like the map below
Please check the code on jsFiddle Sample
<div class="click">
<div class="hide">
<div id="map" style="width:300px;height:140px;"></div>
</div>
</div>
You could wait until the map is loaded by adding an event listener for idle. This event will fire once the map is fully loaded and ready.
google.maps.event.addListenerOnce(map, 'idle', function() {
$('.hide').hide();
});
Here's the JSFiddle.
EDIT:
For anyone with a similar problem, here is the updated JSFiddle with the map positioned offscreen so it remains hidden without using display:none.
you need to wait until map finished render then you set hide a map
because map div was toggle when div on hiding and that make map looking wrong location
init function should look like this
function initialize() {
var latlng = new google.maps.LatLng(48.89376,2.33742);
var settings = {
zoom: 15,
center: latlng,
disableDefaultUI: true,
zoomControl: true,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("map"), settings);
var marker=new google.maps.Marker({
position:latlng,
});
marker.setMap(map);
// on map idle set div hide
google.maps.event.addListenerOnce(map, 'idle', function() {
$('.hide').hide();
});
}
Wonder if anyone can help me, I have setup a google map all works nicely. The only thing I cant work out how to do is to open an info window based on ID from an external html link that's not in the JS.
function initialize() {
// Create the map
// No need to specify zoom and center as we fit the map further down.
var map = new google.maps.Map(document.getElementById("map"), {
mapTypeId: google.maps.MapTypeId.ROADMAP,
disableDefaultUI: true
});
infowindow = new google.maps.InfoWindow();
// Custom markers
var icon = "img/marker.png";
// Define the list of markers.
// This could be generated server-side with a script creating the array.
var markers = [
{ val:0, lat: -40.149049, lng: 172.033095, title: "Title", html: "<div style='text-align:left'><h4 style='color:#0068a6;font-size:16px;margin:0px 0px 10px 0px;'>Title</h4><strong>Telephone</strong><br /><br />Address</div>" },
{ val:1, lat: -41.185765, lng: 174.827516, title: "Title", html: "<div style='text-align:left'><h4 style='color:#0068a6;font-size:16px;margin:0px 0px 10px 0px;'>Title</h4><strong>Telephone</strong><br /><br />Address</div>" },
];
// Create the markers ad infowindows.
for (index in markers) addMarker(markers[index]);
function addMarker(data) {
// Create the marker
var marker = new google.maps.Marker({
position: new google.maps.LatLng(data.lat, data.lng),
map: map,
title: data.title,
icon: icon,
id: data.val
});
// Create the infowindow with two DIV placeholders
// One for a text string, the other for the StreetView panorama.
var content = document.createElement("DIV");
var title = document.createElement("DIV");
title.innerHTML = data.html;
content.appendChild(title);
// Open the infowindow on marker click
google.maps.event.addListener(marker, "click", function() {
infowindow.setContent(content);
infowindow.open(map, this);
map.setCenter(this.position);
console.log(this.id);
});
}
// Zoom and center the map to fit the markers
// This logic could be conbined with the marker creation.
// Just keeping it separate for code clarity.
var bounds = new google.maps.LatLngBounds();
for (index in markers) {
var data = markers[index];
bounds.extend(new google.maps.LatLng(data.lat, data.lng));
}
map.fitBounds(bounds);
}
<p id="1">link to open marker</p>
Any help would be gratefully appreciated

The Golden Goose
Then in your js have a function to open the infowindow (such as show()) which takes the properties from that link (opening id 7).
function show(id){
myid = id;
if(markers[myid]){
map.panTo(markers[myid].getPoint());
setTimeout('GEvent.trigger(markers[myid], "click")',500);
map.hideControls();
}
}
That's the function I used previously with one of the marker managers from v2. You have to make sure you set an id for each marker as you set it and then you can call it.
The one thing I made sure of (to simplify matters) was to make sure the map marker set/array was exactly the same as the sql result I used on the page. That way, using id's was a piece of cake.
I'm using Twitter's Bootstrap for defining my CSS. I have made a page with three tabs. The second tab contains a map built with Google Maps. However when opening the page and switching to the second page with the map, the map is not rendered completely. Once I reload the page with the google maps tab as the selected tab the map loads entirely.
I read some posts that advised people with the same problem to add the following code to the javascript:
google.maps.event.addDomListener(window, 'resize', function() {
map.setCenter(homeLatlng);
});
However this doesn't seem to be the solution. Please find the complete code below:
Javascript:
<script type="text/javascript">
function initialize() {
google.maps.event.addDomListener(window, 'resize', function() {
map.setCenter(homeLatlng);
});
var myLatlng = new google.maps.LatLng(37.4419, -122.1419);
var myOptions = {
zoom: 13,
center: myLatlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
downloadUrl("data.xml", function(data) {
var markers = data.documentElement.getElementsByTagName("marker");
for (var i = 0; i < markers.length; i++) {
var latlng = new google.maps.LatLng(parseFloat(markers[i].getAttribute("lat")),
parseFloat(markers[i].getAttribute("lng")));
var marker = new google.maps.Marker({position: latlng, map: map});
}
});
}
</script>
HTML:
<div class="tab-pane" id="orange" style="background-color:#E3F2FF;">
<div id="map_canvas" style="width:780px; height:400px; overflow:;"></div>
</div>
How can I resolve this? Maybe I can add some javascript that reloads the google maps part once the tab is selected but I don't know how to do this....
Updated code still shows the error:
<div class="tab-pane" id="orange" style="background-color:#E3F2FF;">
<div id="map_canvas" style="width:780px; height:400px; overflow:;"></div>
<script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script>
<script type="text/javascript" src="util.js"></script>
<script type="text/javascript">
function initialize() {
google.maps.event.addDomListener(window, 'resize', function() {
map.setCenter(homeLatlng);
});
var myLatlng = new google.maps.LatLng(37.4419, -122.1419);
var myOptions = {
zoom: 13,
center: myLatlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
downloadUrl("data.xml", function(data) {
var markers = data.documentElement.getElementsByTagName("marker");
for (var i = 0; i < markers.length; i++) {
var latlng = new google.maps.LatLng(parseFloat(markers[i].getAttribute("lat")),
parseFloat(markers[i].getAttribute("lng")));
var marker = new google.maps.Marker({position: latlng, map: map});
}
});
map.checkResize();
}
</script>
</div>
I was battling with this issue as well. I was using a modal form and it rendered the map when it was hidden. When the tab is shown, you need to trigger this code:
google.maps.event.trigger(map, 'resize');
map.setZoom( map.getZoom() );
Hopefully it will work for you. If that doesn't work, here is the link where I found the solution. Maybe there will be another helpful comment.
http://code.google.com/p/gmaps-api-issues/issues/detail?id=1448
There's a lot of solutions here and frankly they're all wrong. If you have to hi-jack the default functionality of Bootstrap tabs, you might as well not use Bootstrap tabs. If you're only calling resize after the tab is shown, you may still have issues with the GMaps interface (zoom level and such). You simply have to initialize the map after the tab is visible.
var myCenter=new google.maps.LatLng(53, -1.33);
var marker=new google.maps.Marker({
position:myCenter
});
function initialize() {
var mapProp = {
center:myCenter,
zoom: 14,
draggable: false,
scrollwheel: false,
mapTypeId:google.maps.MapTypeId.ROADMAP
};
var map=new google.maps.Map(document.getElementById("map-canvas"),mapProp);
marker.setMap(map);
google.maps.event.addListener(marker, 'click', function() {
infowindow.setContent(contentString);
infowindow.open(map, marker);
});
};
$('a[data-toggle="tab"]').on('shown.bs.tab', function (e) {
initialize();
});
You can see a working example in this bootply: http://www.bootply.com/102241
Note: if your interface is still glitchy, it could be this issue:
Google Maps API V3 : weird UI display glitches (with screenshot)
Using the most recent gmaps api, you just need to add this to your styling:
.gm-style img { max-width: none; }
.gm-style label { width: auto; display: inline; }
Works for me after testing different delays :
$(window).resize(function() {
setTimeout(function() {
google.maps.event.trigger(map, 'resize');
}, 300)
});
Hope it helps.
I have solved the problem by using
google.maps.event.trigger(map, 'resize');
inside show function in bootstrap-tab.js means at the time of showing the box you should trigger resize event and will work..
Edit: I have seen another link with the same answer
Google Maps API v3, jQuery UI Tabs, map not resizing
I have seen this link after solving the problem to find out the reason which is still unanswered that why resize event does not works on the click event of the tabs but works in the tab js
this works fine for me, I use jquery tabs
setTimeout(function() {
google.maps.event.trigger(map, "resize");
map.setCenter(new google.maps.LatLng(default_lat, default_lng));
map.setZoom(default_map_zoom);
}, 2000);
from this link https://code.google.com/p/gmaps-api-issues/issues/detail?id=1448
To show a google maps in a hidden div, the div must show before the map is created and loaded. Below is an example:
<div id="map_canvas" style="width:500px; height:500px"></div>
<script>
$(document).ready(function(){
$('#button').click(function() {
$('#map_canvas').delay('700').fadeIn();
setTimeout(loadScript,1000);
});
});
function initialize() {
var title= "Title";
var lat = 50;
var lng = 50;
var myLatlng = new google.maps.LatLng(parseFloat(lat),parseFloat(lng));
var myOptions = {
zoom: 8,
center: myLatlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
var marker = new google.maps.Marker({
position: myLatlng,
title:artTitle
});
// To add the marker to the map, call setMap();
marker.setMap(map);
}
function loadScript() {
var script = document.createElement("script");
script.type = "text/javascript";
script.src = "http://maps.google.com/maps/api/js?sensor=false&callback=initialize";
document.body.appendChild(script);
}
</script>
For me, what it worked was to call the function that renders the map after the, in my case, the modal had shown.
All I had to do was:
$(document).on("shown", "#eventModal", function(){
bindMap(coordinates);
});
You can do the same with the tabs, because they also have a "shown" event.
