Today’s topic is JavaScript and jQuery.
Remember that Java is not JavaScript (see Web Teacher link below), and that
EVENT+OBJECT=ACTION defines what JavaScript does (here is a demo of event handlers).JavaScript is used in HTML & CSS Chapter 9. There are lots of sites and resources that deal with JavaScript, often under the heading of DHTML.. Some other standards include:
- Dynamic Drive with free scripts including Lightbox 2.0 and my Lightbox demo
- Website Abstractions with good Q&A and scripts
- A basic tutorial from Web Teacher
- A PDF from TutorialsPoint
- Good up-to-date overview at Eloquent JavaScript
Most important, understand the code behind this demo that I put together using mainly pre-defined functions, plus the Last updated script on this page.jQuery is a set of prebuilt JavaScript functions that are called by jQuery() or $() (shorthand). The best place to start is the official site. Here is the Getting Started tutorial at jQuery.com,
We'll write a five-line JavaScript that outputs the sum of two integers. Maybe use the tutorial from HTML Dog. For JavaScript dropdowns, now feasible in CSS, you could try Dynamic Drive's Anylink dropdown menu. Also JavaScript.com is a good place to start.
