usage with CGI::Application?
The client is just Javascript and it's best to pick a framework to handle all
the messy browser details for you. I use Prototype, but I like JQuery as well.
The details of how to use them depend on the framework, so I won't put those
examples in here. And then for the backend, using CGI::Application::Plugin::JSON
makes it really easy.
Also, there are several ways to JSON in your application. You can just return
full JSON structures as the body of their reply.
return $self->json_body({ foo => 1, bar => 2});
Sometimes it's nice to return HTML in the body but with some extra information
in your HTTP headers as JSON:
$self->json_header({ valid => 1 });
return $html_tmpl->output;
And then there is JSONP (http://en.wikipedia.org/wiki/JSON#JSONP) which is
basically returning Javascript that executes over some JSON. Really nice and
simple for mashups, etc.
