If you’d like to add some JavaScript goodness to your web pages, but lie awake at night worrying about how you’re going to make them unobtrusive, worry no more. Performer is here to save the day.
Basically, Performer is a small JavaScript library that creates an interface between your carefully-crafted HTML code and the magic of the jQuery or Prototype frameworks. You don’t have to write a single line of JavaScript code to toggle the visibility of elements or load content from other pages (yes, AJAX to the max).
While it has a limited range of features at the moment, there will eventually be many more functions available, with just a dash of additional – completely valid and standard – code.
If you’re interested you should take a look at the main Performer site.
