Zombies Ahead

Zombies AheadSomebody hacked some digital road signs to say “Zombies ahead.”

No, I’m not making this up. More footage.

Despite what some articles are saying, criminal charges will not be filed. The signs are owned by a private company, not by the city, so that company would have to press charges; and the owner said, “It’s Austin. We have a sense of humor. Let it go.

Too funny.

And before you ask, I was nowhere near Austin this weekend.

jQuery lesson learned: Close your tags

I’ve been playing around with JavaScript, so of course I’ve been looking for a JavaScript unit-testing framework — or better yet, a BDD framework, since they tend to make the assertions much more readable. I found Screw.Unit, and fell in love with it for its nested describes, which definitely merit their own blog post.

But I kept using JSSpec for a while, because Screw.Unit is still pretty buggy. JSSpec isn’t a resounding win by any means; its assertion syntax is merely okay, and it leaves you stuck with the traditional test-suite mentality. But it’s got a fantastic test-runner GUI that scales well as you add lots of tests.

Well, this weekend, after writing tests for one of my classes in both JSSpec and Screw.Unit, I finally decided the nested describes were so worth it. So I checked the Screw.Unit distro into my svn repository and started making the Screw.Unit runner better. I made it so you can tell when the tests are done, and whether any failed. I made it automatically scroll to the first failure on the page. I converted all my tests over to Screw.Unit. And I checked it all into my repository.

Then I tried running it in IE. Whoops. Blank page with nothing but some Roman numerals. Guess I should’ve done some cross-browser checking a little sooner…

I did some digging and some troubleshooting, and found that this jQuery syntax:


doesn’t work in IE. Dynamically-created nodes (the $('<h2>')) weren’t being added to the page — the append was doing nothing.

So I posted a question yesterday night on the jQuery list (“append() not working on dynamically-created nodes in IE”), and by this morning, I already had an answer: close the tag.


Explains why some of my own code that created images was working in IE — I was using XHTML <img/> syntax, so my tags were closed.

I tried closing all the tags Screw.Unit was dynamically creating, and it worked like a champ. So there’s my jQuery lesson learned for today: always close your tags. If you don’t, things May Not Just Work.
