If you are a user of jQuery, it is likely that you are aware of Visual jQuery, which is an alternative reference for the jQuery API. Be aware that on the site is documentation for other versions as well. If you are still usnig an older 1.0.x version, you can still see it on their site. Here are the links to the documentation of the various versions. Also included is the blog post announcing the release of each version, with details of bugs fixed, feature changes etc.

There are also several other places that have their own version of the API documentation:

  • jQuery API (the original API page, hopefully it will still be kept up to date when new versions come out)
  • jQuery Documentation Wiki
  • jQuery API Browser by Jörn Zaefferer (one of the key developers of jQuery) There is also an application you can download (no install required) that allows you to look up a function in this API browser by simply highlighting it and pressing Ctrl-Shift-J – Sean Os jQueryHelp
  • gotapi.com also has it (version 1.0.3), but unfortunately the jQuery API page on the site cannot be bookmarked, so it has to be clicked on in the center frame

It is also available in a PDF format for your convenience:

What I have not seen yet, is a CHM (HTML Help) version of the documentation. It would be valuable for browsing offline (although I doubt many web developers now are offline very often) and searching can be easier and faster. Thankfully there is an XML version of the documentation (available on the jQuery API page and in the post announcing 1.1) that could be used to generate a CHM file. I am not sure if the XML files for the older versions (i.e. 1.0.x) are still available though.
