I have been doing Javascript since Mozaic what the only web browser.  I discovered the joys of jQuery about the time V1.1 came out.  Here are some jQuery packages I have written in the past.  

Haven't been doing a lot with packages recently, but I still pull out the jQuery "magic" frequently.

wordFilter (people.apache.org/~gmonroe/wordFilter)

Word filter is a jQuery plug-in I wrote that allows a page to have an "ajax like" search box that will filter information on the page based on user input.  E.g., if you have a list of many articles on a single page, this lets you easily add ways that the article list can be trimmed based on use input.

See the link to the site above for details and a demo.

feedReader (people.apache.org/~gmonroe/feedReader)

We needed a way to support RSS feeds on a site.  So, I wrote this RSS feedReader plug in.  It allows for a lot of different ways to display RSS feeds to users using jQuery as the underlying basis.

See the link above for details and a demo.

urlUtils (never published)

This is a package I wrote to support the HTML/jQuery only sites for the two packages above.  It supplies a couple of features to determine actions to take based on the page URI.  For example, determining which main navigation tab get the "active" CSS styling.  This lets you define actions based on the base URI.  E.g., if the URL starts with the URI of /demos do some jQuery magic.

jQuery Package Site Template (never published)

In creating the packages above,  I needed a quick way to put together delivery sites.  The web server I was using does not support any dynamic languages, so I decided to create a faux dynamic sites using just HTML, CSS, and jQuery.  The end result was a template site designed to showcase jQuery plug-ins that could just be copied and the  wordsmithing started.
