rmarkdown: toggling code blocks in the browser

Question

I'm producing an RMarkdown document with knitr, and I'd like to give my readers the option to show/hide code blocks.

I assume that this will involve adding some JavaScript (e.g. toggle_visibility), but I'm not sure how to add it to a knitr document. Would I add it to the CSS somehow? Or return something with asis = TRUE and put the JavaScript there, as in this example?

Thanks in advance for your help.

You can include additional content in the HTML header, before body, or after body for HTML output from R Markdown documents. I have a simple JavaScript function here, and you may include it in <script></script>. The knitrBootstrap package is much fancier than my naive JS function.

In addition to @Yihui's answer and the one @Shaun Jackman referenced in a comment, someone also pointed me to this example:

Edited to add a minimal example. Note that this example requires jquery.
