A couple years ago I was developing a web interface and using some brand-new JS libs for AJAX functionality. The lib only eval'd JS that was in the html doc header, but there was too much data being returned to fit in the header. What to do?
Some poking around revealed that the JS in the header had access to the body of the html doc, so I wrote a generic 'eval the body' function that was returned in the header. Very useful at the time, especially b/c a different JS lib we were evaluating only eval'd JS from the body, so this was compatible for both JS libs and avoided any size constraints from the header!
Yes, simple, but I felt quite awesome for a whole month after figuring this out :)
