I really like this book!

Designing With JavaScript : Creating Dynamic Web Pages by Nick Heinle
O'Reilly & Associates; ISBN: 1565923006.

JavaScript

Netscape Navigator, starting with version 2.0, includes an interpreter (part of the browser software) that will interpret and execute instructions written in a language called JavaScript. These instructions are part of the Web page and are translated or interpreted by the browser on the client system.

JavaScript is a programming language.

The programs or scripts are part of a Web page and are interpreted when a Web page is retrieved by a browser.

The programs execute on the client.

JavaScript is not Java and not a CGI-Bin program.

The JavaScript language deals with objects, it is object-oriented. Usually work with pre-defined objects relative to a web document or page.

"JavaScript statements embedded in an HTML page can respond to user events such as mouse-clicks, form input, and page navigation. For example, you can write a JavaScript function to verify that users enter valid information into a form requesting a telephone number or zip code. Without any network transmission, the HTML page with embedded JavaScript can check the entered data and alert the user with a dialog box if the input is invalid." - JavaScript Guide. http://developer.netscape.com/docs/manuals/communicator/jsguide4/index.htm

JavaScript includes relatively easy ways, for example, to write instructions that respond to mouse clicks or other mouse movements. A script could collect and verify input from a user before passing it back to a server or an applet.

JavaScript Reference Materials

Netscape provides a good introduction to and all the details for JavaScript in two Web documents:

JavaScript Guide http://developer.netscape.com/docs/manuals/communicator/jsguide4/index.htm

JavaScript Reference http://developer.netscape.com/docs/manuals/communicator/jsref/index.htm

Examples and Exercises:

Buttons and background colors http://www.mwc.edu/ernie/jscript/example1.html

Exercise: modify the source so that there's a button for each color in the rainbow.

Pop-up Windows http://www.mwc.edu/ernie/jscript/example2.html

Exercise: modify the source so your home page pops up upon opening and a page different than the MWC home page pops up when you leave.

Setting the Focus in a form. First take a look at http://www.mwc.edu/ernie/jscript/example3.html

And then http://www.mwc.edu/ernie/jscript/example4.html

Notice how the source is different in the two.

Alert Windows http://www.mwc.edu/ernie/jscript/example5.html

Exercises: Modify the source so the focus is in the form field for favorite food.

Change the alert associated with the pushbutton so it says "Happy Birthday"

Buttons that take you to other Web pages and a pull-down menu http://www.mwc.edu/ernie/jscript/example6.html

http://www.mwc.edu/ernie/jscript/example6a.html

http://www.mwc.edu/ernie/jscript/example6b.html

Exercise: Look at example6.html. We'll deal with the buttons in example6a. Modify the source so the buttons take you to some of the JavaScript tutorials on the next page. Example6b.html deals with the menu. Modify the source so you may select form a collection of JavaScript tutorials.

Substitute page http://www.mwc.edu/ernie/jscript/example7.html
