jQuery is a fast, concise, JavaScript library that simplifies how you traverse HTML documents, handle events, perform animations, and add Ajax interactions to your web pages. jQuery is designed to change the way that you write JavaScript.
jQuery’s syntax is designed to make it easier to navigate a document, select DOM elements, create animations, handle events, and develop Ajax applications.
jQuery also provides capabilities for developers to create plug-ins on top of the JavaScript library.
Features include:
- Feature detection.
- DOM element selections using the cross-browser open source selector engine Sizzle, a spin-off out of the jQuery project.
- DOM traversal and modification (including support for CSS 1-3).
- DOM manipulation based on CSS selectors that uses node elements name and node elements attributes (id and class) as criteria to build selectors.
- XMLHttpRequest data retrieval.
- JSON data retrieval.
- Drag and drop.
- Simple visual effects.
- Animation / advanced visual effects.
