Javascript

Next time we will talk more about javascript as a language, but here is a crash course for you.

jQuery

We discussed the jQuery library, which provides a general interface for listening to events, inspecting, and modifying the DOM of a page, as well as performing AJAX calls. A good site where to learn about jQuery is learn.jquery.com. In particular, I strongly advise you to read the following, which presents the basis of jQuery:

• Selecting elements
• Manipulating elements
• Events (read in particular jQuery Event Basics, introduction to events, and handling events).

Here is some detailed information on methods we used:

• jQuery mouse events
  • DOM insertion, inside and outside (as examples of the operations you can do on the DOM)
  • AJAX shorthand methods (which we used), and the full AJAX method we will use later in the class
