I'm dynamically loading latitude/longitude variables and passing them to the Google Maps Initialize(); function.
function initialize() {
var lat = $('.map_img', '.inview').attr('data-lat');
var lng = $('.map_img', '.inview').attr('data-lng');
var myLatlng = new google.maps.LatLng(lat, lng);
var mapOptions = {
zoom: 15,
center: myLatlng,
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
});
google.maps.event.trigger(map, 'resize');
}
So I'm pulling these coordinates via the data attribute, which is set via a wordpress widget and giving them to Google Maps.
I want to run the function, getting new coordinates every time the user clicks these left/right buttons.
previous
next
$('.btn-prev').click(function () {
//initialize maps script again
initialize();
});
$('.btn-next').click(function () {
//initialize maps script again
initialize();
});
Then the user clicks on a Map image which opens the large map with the new coordinates.
var mapImg = $('.map_img');
var $overlay = $('.overlay'),
resize = true,
map;
mapImg.click(function () {
$overlay.show();
if (resize) {
initialize();
resize = false;
}
});
The problem I'm having is that after the first click the Map is not centered. I had assumed google.maps.event.trigger(map, 'resize'); would solve this problem.
I'm not sure why this is happening so I've created a fiddle to replicate the issue.
http://jsfiddle.net/SEOplay/3CXSs/13/
Help much appreciated.
Try using:
google.maps.event.addDomListener(window, "click", function () {
var center = map.getCenter();
google.maps.event.trigger(map, "resize");
map.setCenter(center);
});
Not efficient code because I'm not excatly sure how it fits into your code, but it will recenter the map every time someone clicks somewhere. It should give you some idea of the code you need, if you have any trouble let me know.
JSFiddle (you also seem to have a bug where it doesn't change the map on the first next/prev click.

I am trying to set a marker to my current location using Javascript. When I load the map, however, while the map will center on my current location, no marker will appear?
Everything looks good, just add marker.setPosition(initialLocation); in the following section:
if (navigator.geolocation) {
navigator.geolocation.getCurrentPosition(function(position) {
initialLocation = new google.maps.LatLng(position.coords.latitude, position.coords.longitude);
marker.setPosition(initialLocation);// ****** missing line ******
map.setCenter(initialLocation);
}, function() {
handleNoGeolocation(browserSupportFlag);
});
};
Here is a working JSFiddle with the necessary changes.
The key is from a Google MAP API sample and will need to be updated with your own, which you can obtain here: Google MAP API.
You may need to reload the JSFiddle example, as there appears to be an issue with the async defer coming from googleapis file. Wait a few seconds and press RUN.
Just make sure the content of variable initialLocation.
If it has the correct lon/lat, marker will appear.
You have to make sure it has correct value before the following:
var marker = new google.maps.Marker({
position: initialLocation,
map: map
});
I am trying to center map to fit all markers. There are lots of example of this, and seems reasonably easy, but I just can't get it to work. Can anyone see what I am doing wrong?
The map can be tested here: http://www.lymphoedema.org.au/the-register/find-a-practitioner-test/ [[Search within 40kms of 3000; then click Map to view the map]].
The map is zoomed right out, and the markers are up in the very top left corner of the map.
Can anyone see what I am doing wrong?
Thank you!

Your code works fine when tested out of a bootstrap tab. So I guess the resize trigger has some implication in the issue.
Try this way:
Declare your bounds variable outside of the initialize function scope (that is where you define your marker and markers variables). By the way, you are missing the map variable declaration too.
var markers = [];
var marker;
var bounds = new google.maps.LatLngBounds();
var map; // missing in your original code
Then fit the bounds too in the bootstrap shown event:
// trigger map resize event when map tab is displayed
$("#mapTab").on('shown.bs.tab', function() {
google.maps.event.trigger(map, 'resize');
map.fitBounds(bounds); // add this line to your code
});
Don't forget to also remove the var declaration here:
//set map bounds
var bounds = new google.maps.LatLngBounds();
Should now be:
//set map bounds
bounds = new google.maps.LatLngBounds();
This is untested but that's all I can think of right now. Let me know if it works or not.
So I display a map on my website and I want after the user has used his mouse to drag around the map and hits a submit button on the site to save the current map status, in order to display it later on, so what I need is to get the current lat and long of the map after the user has used the map.
So afterwards if the user comes back I can display the same map by setiing LatLng
<script

var mapCanvas = document.getElementById('map_canvas');
var mapOptions = {
center: new google.maps.LatLng(44.5403, -78.5463),
zoom: 8,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(mapCanvas, mapOptions);
}
//LE
<script type="text/javascript" src="https://maps.googleapis.com/maps/api/js?v=3.exp&sensor=false&callback=initialize"></script>
<script type="text/javascript">
var map;
function initialize() {
var mapCanvas = document.getElementById('map_canvas');
var mapOptions = {
center: new google.maps.LatLng(44.5403, -78.5463),
zoom: 8,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(mapCanvas, mapOptions);
}
$(window).load(function(){
google.maps.event.addDomListener(window, 'load', initialize);
});
$(document).ready(function(){
var currentLL = map.getCenter(); // you can even store it in localStorage
var currentZoom = map.getZoom();
console.log(currentLL);
});
</script>
Once the user hits the submit button, get the center position(lat/lng) of the Google Maps. This is the wise option to retain the map.
var currentLL = map.getCenter(); // you can even store it in localStorage
var currentZoom = map.getZoom(); // better to save zoom level too
once you return back to maps, set it has center
map.setCenter(currentLL);
map.setZoom(currentZoom);
You can use #Praveen's solution, but don't place that code in document ready function. Place it in a separate function and call that function when the user hits the save button.
Or you can use the Maps API event listeners for that.
You mentioned that you want to save the location when hitting a button and after the user has used his mouse to drag around the map. I suggest that you get the center and zoom when the map becomes idle. That is, when the map becomes idle after panning or zooming. See the documentation.
You could use the dragend event but that would not work if the user only changed the zoom level.
google.maps.event.addListener(map, 'idle', function() {
currentLL = map.getCenter();
currentZoom = map.getZoom();
console.log(currentLL, currentZoom);
});
This way, you always have the latest center and zoom level available.
JSFiddle demo
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>

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.
I have a somewhat strange problem. I have two maps on my site, a big one and a small one. I want to use the big one to show a route to a certain address. I'm now trying to implement the two maps but get a weird problem. The small map is working fine, but on the big map only a small area of the div is filled with the map, the rest is empty. (See the image.)
I use the following code to display the two maps:
function initialize() {
var latlng = new google.maps.LatLng(51.92475, 4.38206);
var myOptions = {zoom: 10, center: latlng,mapTypeId: google.maps.MapTypeId.ROADMAP};
var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
var marker = new google.maps.Marker({position: latlng, map:map, title:"Home"});
var image = '/Core/Images/Icons/citysquare.png';
var myLatLng = new google.maps.LatLng(51.92308, 4.47058);
var cityCentre = new google.maps.Marker({position:myLatLng, map:map, icon:image, title:"Centre"});
marker.setMap(map);
var largeLatlng = new google.maps.LatLng(51.92475, 4.38206);
var largeOptions = {zoom: 10, center: largeLatlng,mapTypeId: google.maps.MapTypeId.ROADMAP};
var largeMap = new google.maps.Map(document.getElementById("largeMap"), largeOptions);
var largeMarker = new google.maps.Marker({position: largeLatlng, map:largeMap, title:"Cherrytrees"});
largeMarker.setMap(largeMap);
}
[..]
jQuery(document).ready(function () {
[..]
initialize();
});
What's going wrong here?
EDIT:
Unfortunately the suggestions below doesn't seem to work. The closes i came is to remove the display:none from the elements and set the elements to hide with jquery
[..]
jQuery(document).ready(function () {
[..]
$("#shadow").add($("#shadowContent"),$("#closebar"),$("#content")).hide();
});
With the following result
Yes, #Argiropoulos-Stavros but, Add it as a listener
google.maps.event.addListenerOnce(map, 'idle', function(){
google.maps.event.trigger(map, 'resize');
map.setCenter(location);
});
It will begin re-sizing after, map rendered.
I think you are using v3.
So google.maps.event.trigger(map, "resize");
Also take a look at here
I fixed it!
I made an own function for the largemap and placed it in the callback when the elements are opened
function largeMap(){
var largeLatlng = new google.maps.LatLng(51.92475, 4.38206);
var largeOptions = {zoom: 10, center: largeLatlng,mapTypeId: google.maps.MapTypeId.ROADMAP};
var largeMap = new google.maps.Map(document.getElementById("largeMap"), largeOptions);
var largeMarker = new google.maps.Marker({position: largeLatlng, map:largeMap, title:"Cherrytrees"});
largeMarker.setMap(largeMap);
}
[..]
$("#showRoute").click(function(e){
e.preventDefault();
$("#shadow").add($("#shadowContent"),$("#closebar"),$("#content")).fadeIn(500);
$("#shadowContent").show().css({'width':'750px','top':'25px','left':'50%','margin-left':'-400px'});
$("#closeBarLink").click(function(l){
l.preventDefault();
$("#shadow").add($("#shadowContent"),$("#closebar"),$("#content")).fadeOut(500);
});
largeMap();
});
Thanks anyway!!
call initialize(); function after you box active.
$(document).ready(function () {
$("#shadow").show(function () {
initialize();
})
});
When you're loading in the large map, try adding this at the end of your map code.
map.checkResize();
When Google Maps first renders on your page, it has the dimensions recorded so that it displays the map images in that size. If you're resizing the map dynamically, you need to tell the API to check the new size.

You are using pop up window with jQuery, and I guest you call initialize() function when document is ready ( $(document).ready(function() {initialize(); }) ).
Try call initialize() function after pop up windown showed.
