I wasn't suggesting he should use the URL() function, just pointing out
that it *can't* be used to build a URL on the client side, and showing a
simple example of how to build a URL on the client side via Javascript (use
of the URL() function was incidental and not central to the point of the
example). In any given case, it may or may not make sense to use the URL()
function to build the base URL (vs. hard-coding it in a .js file), and I
wouldn't state a blanket rule either way (if you're using the web2py
rewrite system, it's generally a good idea to use URL() whenever feasible).
Also, I hadn't realized you made an update to my code example. The update
wouldn't work because it attempts to put Javascript variables inside Python
code that must be executed on the server.
