In this 12-video course, discover how using jQuery, a wrapper for Javascript functionality, can reduce the amount of code required and abstract away complexity of vanilla JS code development. Begin by exploring jQuery syntax and pattern and writing a jQuery method to perform simple tasks. Examine powerful features of jQuery events, and learn to apply methods to register behaviors for full stack development. Next, see how jQuery handles the document object model (DOM), identifying and manipulating content of HTML elements with chaining and using AJAX (Asynchronous JS and XML) to reload content in an HTML page; and adding handlers to work with deferred objects. Move on to callbacks, and how to write asynchronous code with callbacks, and requirements for jQuery plugin development. Learn to implement a jQuery validator to help validate fields in a form; then examine the relationship between CSS (Cascading Style Sheet) selectors and jQuery selectors, by selecting DOM elements using CSS-related properties. Associating arbitrary data with DOM elements is also covered. The exercise involves using AJAX to call an API on the public domain.
