Google map v3 hidden tabbed panels not centering

Hiya,
I am trying to put a different google map on each tab of a tabbed panel. The map on the default page works fine but the ones on other tabs appear only in the top left of the container div. From what I have read this is due to the hidden container divs having a size(0,0) so the google map centres in the top left and doesn't resize when the tab is activated.

I realise this is a known bug and a lot of people seem to have fixed it in version 2, but not version 3 google maps. Unfortunately none of the fixes seem to have worked for me. I think the code fixes might work but I'm sure sure where to insert them into the javascript?

I'm hoping someone could help me work out what code to put where to get the google maps on the hidden tabbed panels to either resize when the tab is activated, or be made permanetly the correct size?

Code below:

(header)
<script type="text/javascript">

function initDexGoogleMap(canvas, width, w_unit, height, h_unit, latitude, longitude, p_zoom, p_mapType, p_navControl, p_navStyle, p_navPosition, p_mapTypeC, p_mapTypeCStyle, p_mapTypeCPosition, p_scaleC, p_scaleCPosition, p_draggable, p_disableDoubleClickZoom, p_keyboardShortcuts, p_trafficL, p_bikeL, p_panoramio )

{document.write('<div id="'+canvas+'"></div>');

document.getElementById(canvas).style.width = width + w_unit; document.getElementById(canvas).style.height = height + h_unit;

var latlng = new google.maps.LatLng(latitude,longitude);
var myOptions = {zoom: p_zoom, center: latlng, navigationControl: p_navControl, navigationControlOptions: {style: p_navStyle, position: p_navPosition}, mapTypeControl: p_mapTypeC, mapTypeControlOptions: {style: p_mapTypeCStyle, position: p_mapTypeCPosition}, scaleControl: p_scaleC, scaleControlOptions:
{position: p_scaleCPosition}, mapTypeId: p_mapType, draggable: p_draggable, disableDoubleClickZoom: p_disableDoubleClickZoom, keyboardShortcuts: p_keyboardShortcuts};

var map = new google.maps.Map(document.getElementById(canvas), myOptions);

(Body)

<div id="DEX_GContainer0">
<script type="text/javascript">var my_DEX_GContainer0 = initDexGoogleMap
("DEX_GContainer0","450","px","450","px",51.5313695, -0.1031838,16,google.maps.MapTypeId.ROADMAP,true,google.maps.
NavigationControlStyle.DEFAULT,google.maps.ControlPosition.TOP_LEFT,true,google.maps.MapTypeControlStyle.DEFAULT,google.maps.ControlPosition.TOP_RIGHT,true,google.maps.ControlPosition.BOTTOM_LEFT,true,false,true,false,false,false); addMarker(my_DEX_GContainer0,51.5313695,-0.1031838,false,"Fitness%20First","","","click","");
</script>
</div>

Thanks!

please send a link where i can see the problem to investigate.

Hi,
Thank you, link is below. The map works perfectly on the default 'London' tab but doesn't work properly on the 'South West' tab.

Locations.html

Thanks

i am not able to see the page at the link you provide. All i see is:

Hi,
OK, the site must still be propagating as I only transferred it to the new host this morning.

Locations.html is the testing area I'm using and has exactly the same code,

I have got to the point where the map in the 'South West' tab map will resize if the map is dragged slightly by adding the following code:

var map = new google.maps.Map(document.getElementById(canvas), myOptions);

google.maps.event.addListener(map, "idle", function()
{google.maps.event.trigger(map, 'resize'); });

How can I get the map to resize without the user having to drag it? (maybe by zooming in and back out again automatically?)
How can I get the map to recentre around the marker rather than still being centred in the top left?

Thanks

Hi,
I have read that possible solutions would be:

google.maps.event.trigger({map}, 'resize'); {map}.setCenter({marker}.getPosition());

map.setZoom( map.getZoom() );

this.map.setZoom( this.map.getZoom() - 1);
this.map.setZoom( this.map.getZoom() + 1);

map.setZoom(map.getZoom());
map.fitBounds(bounds);

I haven'be been able to get any of these to work, but I'm not sure I'm using them correctly. Where could these go and what would it look like in my code above?

Really appreciate any help anyone can give me!

Thanks

It looks like you have found the solution to this? When i visit your page the maps appear to be loading ok?

Hi, I found a workaround using jQuery tabs rather than sort tabs and the standard google map rather than the webassist google map. I don't mind using jQuery tabs but it would be nice to use the wabassist google map rather than the basic one, but I couldn't get the maps to work.
