This guide is an introduction to the jQuery library. Knowledge of javascript and the document object model (DOM) is required. It starts from ground up and tries to explain details where necessary. It covers a simple hello world example, selector and event basics, AJAX, FX and usage and authoring of plugins. This guide contains no "click me" examples. The intention of providing only "copy me" code is to invite you to try it for yourself. Copy an example, see what it does, and modify it.
