I will try these suggestions but I doubt they will work as the
javascript portions of get_page have both single and double quoted
sections that probably can't be replaced without breaking the
javascript.
What's frustrating about jQuery and javascripted actions in context of
web development in general, and in this case, my web2py app, is that
they break the DRYness of my code. It seems like I always have to
write one set of page-rendering code for the initial page generation,
and then another set of html to generate the sub-sections of the page
that will be created in response to a javascript event. I really want
to render the different sections of the page from the same code at all
times. Does anyone have any insights into how to structure your code
to be DRY while still being able to pull off a page that can be
generated in its entirety by a straight URL call or in pieces by ajax
calls that target specific subsections of the page? It assumes a page
that has all sorts of different kinds of things, including css
widgets, straight html, and javascripts.
