I am writing a Python CGI and am needing to pass a data value from Python to
a javascript function. My understanding is that I should use JSON as the
middleman. However, I have not found a good example of doing this. The
piece of data is a simple integer, but I converting that to a string first.
Here is what I am trying, but unsuccessfully. I know this code is broken
in at least two places. I may be going about this completely the wrong
way. Any help would be appreciated.
Thanks,
Bill Allen
