Is there a way to make the tests run under Safari? I guess there is given you have proper reports of the results.

Immediately after, I ran into <a href="http://bugzilla.opendarwin.org/show_bug.cgi?id=3374" rel="nofollow">bug 3374</a>. But 3374 is a lot easier to work around. In any case, now that I'm learning the DOM, I'm even more appreciative of your efforts. Thanks! Coincidentally, I hit that preventDefault bug today. Immediately after, I ran into bug 3374.

The ultimate test application is almost working (just kidding and sorry for Czech locale, English localization pack (external XML file) is pending, but if you know XMLSpy you get the idea ;) at http://www.whoa-framework.org/website/vas/1.0/?/editor/xml . Still needs a little bit of tweaking for Safari, but god i'd love to replace Firefox with Safari for such particular applications (please note that the code is actually about three years old and almost intact, no sign of Ajax at that time:) and worked on Mozilla Gecko since its 0.8 version with IE since 6.0). Now Safari is coming very close.. More on http://www.whoa-framework.org/?/product/bender . Great!

I think that folks do get discouraged when they encounter something like the Gmail bug where...just...nothing...happens. And I hate to say it, but I think the test "people" use these days for browser excellence is not some oh-so-subtle rendering in CSS2, but do the fancy AJAX things of the world (and yeah, interactive SVG too) work? In other words, do Gmail and Google Maps work as advertised? And of course, they wonder about that Google Earth, but that's not in your court. Ah, that nasty bug 4788.

I think it is actually a JS parsing problem though, as this workaround works: function f(evt) { evt.preventDefault(); } document.getElementById('foo').addEventListener('click', f, false); I also fixed the problem I found with stopPropagation, just waiting for code review: <a href="http://bugzilla.opendarwin.org/show_bug.cgi?id=5180" rel="nofollow">5180</a> And finally, I'm afraid we can't make any commitments about when specific fixes will make it into releases. The best we can do is let you know after the fact.

That test (a good example) should read: <a href="http://www.google.com" onclick="event.preventDefault()">click here</a> And, of course, the test should be made using a JS-assigned handler: <a href="http://www.google.com" id="foo">click here</a> <script type="text/javascript"> document.getElementById( 'foo' ).addEventListener( 'click', function( evt ){ evt.preventDefault( ) }, false ); </script> Er, didn’t realize HTML markup was allowed.

Also, maciej, I think a more accurate preventDefault test would be: <a href="http://www.google.com/" rel="nofollow">click here</a> since the span tag doesn't have a default click action.
