jQuery is a fast and concise JavaScript framework. It is another excellent JavaScript code library (or JavaScript framework) after Prototype. The purpose of jQuery's design is "write less, do more", which means writing less code and doing more things. It encapsulates common JavaScript function codes, provides a simple JavaScript design pattern, and optimizes HTML document operations, event processing, animation design and Ajax interaction.
