Google Map in Bootstrap Tab

I'm trying to get a Google Map to appear in a vanilla Bootstrap tab. I built a fiddle taken directly from the Bootstrap docs, with the Gmap script pretty much exactly like Google recommends doing it too.

I am dumping the

object to console.dir and it has been initialized properly. In earlier projects I'd been able to display maps in tabs using the
function-- but it doesn't seem to work with Bootstrap.

Has anyone gotten this working?

Here's the generic jsfiddle-- http://jsfiddle.net/B4zLe/4/

EDIT: adding code


var map;

jQuery(function($) {
$(document).ready(function() {
var latlng = new google.maps.LatLng(-34.397, 150.644);
var myOptions = {
zoom: 8,
center: latlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
google.maps.event.trigger(map, 'resize');

$('a[href="#profile"]').on('shown', function(e) {
google.maps.event.trigger(map, 'resize');


<div class="bs-docs-example">
<ul id="myTab" class="nav nav-tabs">
<li class="active"><a href="#home" data-toggle="tab">Home</a></li>
<li><a href="#profile" data-toggle="tab">Map</a></li>
<div id="myTabContent" class="tab-content">
<div class="tab-pane fade in active" id="home">

You're a little overoptimistic in how powerful the "resize" event is. From the documentation:

  • resize: Developers should trigger this event on the map when the div changes size: google.maps.event.trigger(map, 'resize')

In other words, resize won't do anything fancy like size the map to the window, but will only size it to the container it's in - in this case, the "map_canvas" div. However, this div has no dimensions, so the map has zero size.

Since you added some listeners to ensure that the map will change to the size of it's parent, this is a pretty easy fix - just add some code to modify the parent div to the desired size, and the map will resize to it. For example:

$("#map_canvas").css("width", 400).css("height", 400);

will size it to 400x400. Here's an example, you should be able to change it to whatever you'd like.
