This document is a visual cheat sheet for jQuery selectors and core functions in jQuery 1.5. It provides descriptions and examples for various jQuery selectors including basic, hierarchy, content filter, child filter selectors. It also summarizes some core jQuery functions like get, index, length, selector and more.
