Web Development - JavaScript

Why is this important?

XHTML does a great job of displaying information. But, when you really want to get some work done, you'll need JavaScript. JavaScript is the programming language for browsers and it allows you to respond to button clicks, validate form fields, and a wide variety of other things.

No more static web pages.

Note: You don't say water when you mean watermelon. So.... don't say Java when you mean JavaScript. They are two very different languages.

JavaScript Reference Pages - Save these as bookmarks for quick reference

From NetScape

This is a great site that references all the keywords and functions available with JavaScript. Right now Part 5, Language Elements will be of most interest to you. For later there's lists of all the events and a list of all the objects available to you as you explore JavaScript deeper in the future.

Even though Netscape is no longer around, it is this group that wrote JavaScript. Netscape has morphed into what we know as FireFox.

 

From W3Schools

W3Schools always is a great place for a fast lookup. Here's their JavaScript Reference page.
