jQuery Roundup: Rails, Wordpress, and new plugins

jQuery has had a recent set of interesting news, so we thought we should write it up: jQuery works nicely with Rails. Geoff Buesing assumed that switching his Rails application from Prototype to jQuery would be a pain, but then discovered that you can write jQuery-formatted Javascript with RJS templates, out-of-the-box, no special helpers or modifications necessary.

The trick is to use the RJS element proxy syntax -- page['someid'] -- which outputs the Prototype syntax $('someid'). Just replace someid with a jQuery selector, and method_missing magic will handle the arbitrary jQuery methods chained to it.

Some examples:

PLAIN TEXT

RUBY:

page["#posts"].append render(:partial => 'post', :locals => {:post => @post}) #=> $("#posts").append("Post #29 info…");page[".hide-this"].hide #=> $('.hide-this').hide(); page["#foo"].html("bar").append("baz") #=> $("#foo").html("bar").append("baz"); page["h1"].add_class "make-red" #=> $("h1").addClass("make-red");

Ryan Dunphey wanted an OS X dashboard widget to give him "simple, searchable, offline access to the API", so while on a plane, he developed it.
