jQuery Basics

  • Fabio Nelli


In the previous chapter, you learned about the DOM tree and saw how HTML documents are composed of many elements that can be created, modified, and deleted from the initial context. These operations are performed by the browser via JavaScript commands that, as discussed previously, can be executed either at the time of page loading or as a result of events that follow. A JavaScript library that manages all these operations in a simple and well-established manner has been developed for this purpose. This library is jQuery, and it is completely open source. It was created in 2006 by Jon Resig and continues to be improved on by a team of developers. Because of its usefulness, compared with classic JavaScript, and its ability to manipulate DOM elements, jQuery is currently the most widely used JavaScript library and constitutes a point of reference for all web developers.
