In some of the info about the new version, they talk about the
new feature:
<http://jquery14.com/day-01>
Nested param serialization (jQuery.param() Documentation,
Commit 1, Commit 2)
jQuery 1.4 adds support for nested param serialization in
jQuery.param, using the approach popularized by PHP, and
supported by Ruby on Rails. For instance, {foo: ["bar", "baz"]}
will be serialized as “foo[]=bar&foo[]=baz”.
In jQuery 1.3, {foo: ["bar", "baz"]} was serialized as
“foo=bar&foo=baz”. However, there was no way to encode a
single-element Array using this approach. If you need the old
behavior, you can turn it back on by setting the traditional
Ajax setting (globally via jQuery.ajaxSettings.traditional or on
a case-by-case basis via the traditional flag).
So rather than changing the name of params you use, change the
behaviour of jQuery instead:
<http://api.jquery.com/jQuery.param/>
jQuery.ajaxSettings.traditional = true;
Note, I haven't tried the above yet. But I think that's because
MyApp uses Params::Nested which effectively normalizes the param
names for $c->req, so the extra brackets haven't been an issue.
In either case, I had forgotten about that factoid in the
release docco; thanks for the notice.
