I've been working on a Twitter Bootstrap site recently. It contains modal which require a little interaction within the modal box itself. So here is an example of how to achieve this, this time using forms. First, I load the form into the modal, then I handle the form still within the modal. Most of the code is taken directly from the Twitter Bootstrap website. The only real difference is that I've loaded jQuery and the bootstrap.min.js before the body. I've highlighted the important parts in red.
