Some time ago, we were working on a website that required a contact form with the ability to attach a file. This sounds like, at this point in web design, it should be incredibly simple. Imagine my chagrin as I learned that, in fact, styling the FileUpload Object had a smack of Holy Grail-ness to it. Well, at least as far as HTML form objects are concerned.

A lot of people have had similar ideas on how to handle this. I suppose it all started with Michael McGrady‘s solution, which was followed closely by an improvement on McGrady’s technique from Peter-Paul Koch over at Quirksmode. The closest thing I found to a satisfactory solution, though, came from Shaun Inman. His solution was definitely the right idea, but it wasn’t exactly full-featured, and I wanted it built in my favorite Javascript framework.

Like Shaun, I don’t think that the text-box is an appropriate UI element for a file upload in 2008 (who wants to type c:\Documents and Settings\Paul\My Documents\My Photos\2008-06-02-Me.jpg into a field that only shows 25 characters?!). Further, every implementation I’ve ever seen that makes use of a text-box is wonky. So I wanted to do a Safari-style upload.

I appreciate the cleanliness of Safari’s implementation. It’s the best default browser implementation out there…but it’s still not good enough!

Shaun’s really clever idea involves setting the input’s opacity to zero and then using a little javascript function to keep the button under your mouse while you’re hovering inside the input’s parent container. With the hardest part figured out, I had two additional goals:

1. First, I needed it to display the file name of the uploaded file. One problem with Shaun’s is that I couldn’t even verify if I’d successfully attached a file.
2. Second, I agree with Peter on the importance of being able to clear the file from the form. No implementation I’ve seen allows you to do that, so I added the feature.

To see how it’s done, you can either read the walkthrough or else download a working example.
