    copied!<p>I'm playing with the IndexedDB API from html5 spec in both Firefox and Chrome.</p> <p>There something that's not working as expected I and want to share it here because I don't know if it's my fault or a browser bug.</p> <p>According to the <a href="http://www.w3.org/TR/IndexedDB/#widl-IDBDatabase-onversionchange" rel="nofollow">API</a>, there's an event called <strong>onversionchange</strong> that's fired when you open a connection to a local database and the version number used is greater than the databases one. My problem is that this event is being fired in Firefox but not in Chrome.</p> <p>Some sample code trying several modes:</p> <pre><code>var db; var DB_VERSION = 5; var openRequest = iDb.open("test_db", DB_VERSION, function() { console.log("This is the place where I can change db structure"); }); openRequest.onSuccess = function(event) { db = openRequest.result; }; openRequest.onversionchange = function(event) { console.log("This is the place where I can change db structure"); }; openRequest.onupgradeneeded = function(event) { console.log("This is the place where I can change db structure"); }; </code></pre> <p>onversionchage event is not being fired even when I change the version number.</p> <p><strong>UPDATE</strong> As <em>ebidel</em> has answered, Chrome implementatio does not follow the currently specification so, in order to have a cross broswser client code, we need to handle two situations: <em>onversionchange</em> event and <em>database.version</em> manual comparision.</p> <p>Here are a couple on links with code example: <a href="http://groups.google.com/a/chromium.org/group/chromium-discuss/browse_thread/thread/5d96ca12c2d092b6?pli=1" rel="nofollow">Chromium google group</a> and <a href="http://www.html5rocks.com/en/tutorials/indexeddb/todo/" rel="nofollow">HTML5 Rocks!</a></p>
