Like the “w2p:componentComplete” event I added a while back, this is
another event that I use in my website, and I thought it would be
helpful to share it with others. This way, you can easily catch when a
web2py component starts loading, and write a handler for whatever
reason (in my case, determining when the user is navigating to a new
page through a smooth loading function piggybacking off of the web2py
component system)
