JavaScript the Definitive Guide

by David Flanagan

There have been many changes in the world of web programming with JavaScript since the third edition of this book was published, including:

Second and third editions of the ECMA-262 standard have been published, updating the core JavaScript language. Conformant versions of Netscape's JavaScript interpreter and Microsoft's JScript interpreter have been released.
The source code for Netscape's JavaScript interpreters (one written in C and one written in Java) has been released as open source and is available to anyone who wants to embed a scripting language in his application.
The World Wide Web Consortium (W3C) has published two versions (or levels) of a Document Object Model (DOM) standard. Recent browsers support this standard (to varying degrees) and allow client-side JavaScript to interact with document content to produce sophisticated Dynamic HTML (DHTML) effects. Support for other W3C standards, such as HTML 4, CSS1, and CSS2, has also become widespread.
The Mozilla organization, using source code originally contributed by Netscape, has produced a good fifth-generation browser. At the time of this writing, the Mozilla browser is not yet at the 1.0 release level, but the browser is mature enough that Netscape has based its 6.0 and 6.1 browsers upon the Mozilla code base.
Microsoft's Internet Explorer has become the overwhelmingly dominant browser on desktop systems. However, the Netscape/Mozilla browser remains relevant to web developers, especially because of its superior support for web standards. In addition, minor browsers such as Opera and Konquerer should be seen as equally relevant.
Web browsers (and JavaScript interpreters) are no longer confined to the desktop but have migrated to PDAs and even cell phones.

In summary, the core JavaScript language has matured. It has been standardized and is used in a wider variety of environments than it was previously. The collapse of Netscape's market share has allowed the universe of desktop web browsers to expand, and JavaScript-enabled web browsers have also become available onnon-desktop platforms. There has been a distinct, if not complete, move toward web standards. The (partial) implementation of the DOM standard in recent browsers gives web developers a long-awaited vendor-independent API to which they can code.

JavaScript Essentials

By Neil Smyth

Before JavaScript was created, a typical web browsing experience consisted largely of displaying static pages of information. Any type of user interaction with a web page usually involved the browser sending information back to the web server where some type of server based script or other program would validate the user's data input. The server would then send back either a static error page if the user had entered invalid data or, assuming successful validation, return a static page to the web browser containing the results of the transaction. In addition, the lack of a mechanism to implement dynamic web page content and behavior dictated that an entirely new web page be loaded in order to display new information.

It quickly became clear that a way of performing "client-side" or "web browser-side" processing was needed. The original intent for JavaScript, therefore, was to address this need by facilitating such tasks as validating user input before it is transmitted to the web server, and creating dynamic web page content and layouts independently of the web server (for example, displaying different text depending on a user's actions within the page).

JavaScript met and, indeed, exceeded these requirements by providing an extremely flexible and intuitive scripting language. The problem today is that, as with any useful technology, JavaScript has been used in ways never anticipated by its original authors. As a result, the potential uses of JavaScript have grown far beyond the needs of the average person looking to add dynamic behavior to web pages. The result of this is that JavaScript book authors also feel the need to cover every possible capability of JavaScript, often to the extent that the average JavaScript reference book now runs to over 1,000 pages.

The purpose of this book, therefore, is to provide the essentials of JavaScript so that anyone with a web site can use this powerful scripting language quickly and effectively without having to learn things that, whilst within the capabilities of JavaScript, aren't actually needed by the average web designer. That said this book does not take any shortcuts. It provides detailed and in depth knowledge of all aspects of JavaScript from language basics through to advanced topics.
This book is designed to provide a detailed and comprehensive, yet easy to follow, guide to developing powerful, dynamic web pages using JavaScript. It could be said that the object of JavaScript Essentials is to provide you with everything you need to use JavaScript, and nothing that you don't.

Simply JavaScript

By Kevin Yank and Cameron Adams

What’s Covered in this Book?

Chapter 1: The Three Layers of the Web: A big part of learning JavaScript is learning when it’s the right tool for the job, and when ordinary HTML and CSS can offer a better solution. Before we dive into learning JavaScript, we’ll take a little time to review how to build web sites with HTML and CSS, and see just how JavaScript fits into the picture.
Chapter 2: Programming with JavaScript: JavaScript is a programming language. To work with it, then, you must get your head around the way computer programs work—which to some extent means learning to think like a computer. The simple concepts introduced in this chapter—statements, variables, expressions, loops, functions, and objects—are the building blocks for every JavaScript program you’ll ever write.
Chapter 3: Document Access: While certain people enjoy writing JavaScript code for its own sake, you wouldn’t want to run into them in a dark alley at night. As a well-adjusted web developer,you’ll probably want to use JavaScript to make changes to the contents of yourweb pages using the Document Object Model (DOM). Lucky for you, we wrote a whole chapter to show you how!
Chapter 4: Events: By far the most eventful portion of this book (ha ha ha … I slay me), this chapter shows you how to write JavaScript programs that will respond to the actions of your users as they interact with a web page. As you’ll see, this can be done in a number of ways, for which varying degrees of support are provided by current browsers.
Chapter 5: Animation: Okay, okay. We can talk all day about the subtle usability enhancements that JavaScript makes possible, but we know you won’t be satisfied until you can make things swoosh around the page. In this chapter, you’ll get all the swooshing you can handle.
Chapter 6: Form Enhancements: I know what you’re thinking: forms are boring. Nobody leaps out of bed in the morning, cracks their knuckles, and shouts, “Today, I’m going to fill in some forms!” Well, once you trick out your forms with the enhancements in this chapter, they just might. Oh, and just to spice up this chapter a bit more, we’ll show you how to make an element on your page draggable.
Chapter 7: Errors and Debugging: When things go wrong in other programming languages, your computer will usually throw a steady stream of error messages at you until you fix the problem. With JavaScript, however, your computer just folds its arms and gives you alook that seems to say, “You were expecting, maybe, something to happen?” No, English is not your computer’s first language. What did you expect? It was made in Taiwan. In this chapter, we’ll show you how to fix scripts that don’t behave the way they should.

JavaScript cheat sheet

The JavaScript cheat sheet is designed to act as a reminder and reference sheet, listing methods and functions of JavaScript. It includes reference material for regular expressions in JavaScript, as well as a short guide to the XMLHttpRequest object. A description of what is on the cheat sheet follows, or if you are impatient, you can go straight to the full size JavaScript cheat sheet.

JavaScript has a huge number of methods and functions available. The cheat sheet lists these in various sections. On the left is a list of simple methods in JavaScript. On the right are DOM methods. Functions are in their own section at the bottom of the page.

The XMLHttpRequest object is relatively new to JavaScript. It is used to make requests and receive responses in XML format from a server, allowing developers to create interactivity with the server without the need for page refreshes (see the "Live Search" on the right of this page for an example). This section of the cheat sheet is a short reference to the object, containing a list of useful methods and properties, the syntax for creating the object in different browsers, and the various readyState values.

Acrobat JavaScript Scripting Guide

Welcome to the Adobe Acrobat JavaScript Scripting Guide. This scripting guide is designed to provide you with an overview of how you can use Acrobat JavaScript to develop and enhance standard workflows, such as:

Printing and viewing
Spell-checking
Stamping and watermarking
Managing document security and rights
Accessing metadata
Facilitating online collaboration
Creating interactive forms
Customizing interaction with Web Services
Interacting with databases

Here you will find detailed information and examples of what the Acrobat JavaScript capabilities are and how to access them, as well as descriptions of the usage of the SDK tools. Acrobat JavaScript is a powerful means by which you can enhance and extend both Acrobat and PDF document functionality.

Acrobat JavaScript is a language based on the core of JavaScript version 1.5 of ISO-16262, formerly known as ECMAScript, an object-oriented scripting language developed by Netscape Communications. JavaScript was created to offload Web page processing from a server onto a client in Web-based applications. Acrobat JavaScript implements extensions, in the form of new objects and their accompanying methods and properties, to the JavaScript language. These Acrobat-specific objects enable a developer to manage document security, communicate with a database, handle file attachments, manipulate a PDF file so that it behaves as an interactive, web-enabled form, and so on. Because the Acrobat-specific objects are added on top of core JavaScript, you still have access to its standard classes, including Math, String, Date, Array, and RegExp.

JavaScript Authoring Info

By John Russell

JavaScript (aka ECMAScript) is a relatively easy way to make your website visually attractive to clients and other viewers by adding interactivity and dynamics to HTML pages. This page explains why one would use JavaScript in their HTML website design. JavaScript can also be used as a basis for writing utility programs that are platform independent. Programming concepts learned in JavaScript can be rolled over into Java or any modern object oriented language. This page also has links to JavaScript code repositories and references for those who prefer not to reinvent wheels. And finally for those who do prefer to roll their own there are my programming notes, some introductory tutorials, small projects, larger projects and form projects pages.

Why Use JavaScript

Why should a webpage author use JavaScript in addition to HTML?
Javascript adds user interactivity.
Javascript enhances visual displays.
Javascript allows client-side user form validation.
Javascript provides more seamless integration with user plug-ins.
Javascript allows access to some system information that HTML does not.

Language Design Issues

Because JavaScript uses a high-end approach to security (leaving lapses in the domain of the browser) there are some applications that it is not appropriate for:
JavaScript does not have user file access. You must use cut/paste techniques to input or save data.
JavaScript does not have a print method. You must create an HTML page and use the browser menu to print.
JavaScript cannot run programs on the host machine unless it is through browser plug-ins or associations allowed within the browser.
JavaScript has no access to the user environment other than what the browser provides. Hence no access to the Windows registry is possible.
JavaScript is definitely not a system programming language! Use Java or C++ for this type of activity.

Core JavaScript Reference

This book is a reference manual for the core JavaScript language for version 1.5. JavaScript is Netscape's cross-platform, object-based scripting language. Core JavaScript can be extended for a variety of purposes by supplementing it with additional objects.

JavaScript version 1.5 provides the following features and enhancements:

Runtime errors. Runtime errors are now reported as exceptions.
Number formatting enhancements. Number formatting has been enhanced to include Number.prototype.toExponential, Number.protoytpe.toFixed and Number.prototype.toPrecision methods. See page 127, page 128, and page 129.
Regular expression enhancements:
(1) Greedy quantifiers - +, *, ? and {} - can now be followed by a ? to force them to be non-greedy. See the entry for ? on page 148.
(2) Non-capturing parentheses, (?:x) can be used instead of capturing parentheses(x). When non-capturing parentheses are used, matched subexpressions are not available as back-references. See the entry for (?:x) on page 148.
(3) Positive and negative lookahead assertions are supported. Both assert a match depending on what follows the string being matched. See the entries for (?=) and (?!) on page 148.
(4) The m flag has been added to specify that the regular expression should match over multiple lines. See page 146.
Conditional function declarations. Functions can now be declared inside an if clause. See page 221.
Function expressions. Functions can now be declared inside an expression. See page 254.
Multiple catch clauses. Multiple catch clauses in a try...catch statement are supported. See page 231.
Constants. Readonly, named constants are supported. This feature is available only in the C implementation of JavaScript. See page 215.
Getters and Setters. JavaScript writers can now add getters and setters to their objects. This feature is available only in the C implementation of JavaScript. See Defining Getters and Setters in Chapter 7 of the Core JavaScript Guide for information about this feature.

Teach Yourself JavaScript in a Week

By Arman Danesh

In this book we are going to take a look at JavaScript—the internal scripting language Netscape has developed and included in the Navigator browser.

JavaScript is an evolving tool, like so many tools associated with the Internet and the World Wide Web. Still, the future of JavaScript is sufficiently clear that many people have already developed sophisticated Web-based applications using the language.

We start by taking a broad look at Netscape Navigator 2.0, the current version of the popular Web browser, which some estimates say commands more than 80 percent of the Web browser market. Following this, we take an introductory look at JavaScript and its relationship with Java and its place in the Netscape suite of Web development tools.

Once this is done, we will be ready to look at the nuts and bolts of the JavaScript language and learn how to apply them to real-world scenarios on the Web. JavaScript can be used to add a wide range of interactivity and functionality to Web pages including the following:

Dynamic forms that include built-in error checking
Spread sheets and calculators
User interaction in the form of warning messages and confirmation messages
Dynamic changes to text and background colors
The ability to analyze URLs and access URLs in a user's history list
The capability to open, name, clear, and close new windows and direct output to specific frames

These types of functions already appear in numerous Web sites on the World Wide Web, and it is expected that the number will grow rapidly in early 1996 now that Navigator 2.0 has moved from being a beta product to commercial release software.

Throughout the book, you will have the opportunity to develop several small scripts that you can immediately use in your own Web pages.

Finally, we close with a review of the future of JavaScript and where it seems to be heading. We will consider Netscape's plans as well as announcements from other companies to include JavaScript in their products.

JavaScript The Definitive Guide - Fourth Edition

by David Flanagan

This edition of JavaScript: The Definitive Guide has been thoroughly updated in light of the changes I just described. Major new features include complete coverage of JavaScript 1.5 and the third edition of the ECMA-262 standard on which it is based, and complete coverage of the Level 2 DOM standard.

Throughout the book, the focus has shifted from documenting particular JavaScript and browser implementations ( JavaScript 1.2, Netscape 4, Internet Explorer 5, etc.) to documenting the standards upon which those implementations are (or ought to be) based. Because of the proliferation of implementations, it is no longer practical for any one book to attempt to document -- or for any one developer to attempt to understand -- every feature, proprietary extension, quirk, and bug of every implementation. Focusing on the specifications instead of the implementations makes this book easier to use and, if you take the same approach, will make your JavaScript code more portable and maintainable. You'll particularly notice the increased emphasis on standards in the new material on core JavaScript and the DOM.

Another major change in this edition is that the reference section has been split into three distinct parts. First, the core JavaScript material has been separated from the client-side JavaScript material (Part IV) and placed in a section of its own (Part III). This division is for the convenience of JavaScript programmers who are working with the language in an environment other than a web browser and who are not interested in client-side JavaScript.

Second, the new material documenting the W3C DOM has been placed in a section of its own (Part V), separate from the existing client-side JavaScript material. The DOM standard defines an API that is quite distinct from the "legacy" API of traditional client-side JavaScript. Depending on the browser platforms they are targeting, developers typically use one API or the other and usually do not need to switch back and forth. Keeping these two APIs distinct also preserves the organization of the existing client-side reference material, which is convenient for readers of the third edition who upgrade to this edition.

In order to accommodate all the new material without making the book much, much larger, I've gotten rid of reference pages for the trivial properties of objects. These properties are already described once on the reference page for the object, and putting another description in a reference page of its own was redundant and wasteful. Properties that require substantial description, as well as all methods, still have reference pages of their own. Furthermore, the design wizards at O'Reilly have created a new interior design for the book that remains easy and pleasant to read but takes up less space.

ppk on JavaScript

By Peter-Paul Koch

The purpose of this book is to offer easy access to all the basic JavaScript knowledge I've gathered in the eight years I've been a professional Web developer.

Since this book reflects my knowledge, it also reflects the limitations of that knowledge. I am a Web developer, not an application developer—which means I talk about browser incompatibilities, accessibility, low-level syntax, and cooperation with the HTML structural layer, instead of modules, design principles, and abstraction layers.

During the eight years that I've earned a living by making Web sites, I have used some JavaScript features extensively but largely ignored others. I always took the tools I needed to do the job I was paid to do, and it turns out that the JavaScript toolbox contains many features I don't need in my day-to-day use.

Obviously, I cannot teach you to use a tool that I myself don't understand. Therefore this book only treats those language features I work with. Object-oriented JavaScript, for instance, is conspicuously absent because I've never seen the need to use it.

Besides, a book has a fixed length, and therefore I had to make choices—occasionally very difficult ones. In the end I selected those JavaScript features that I feel you must understand in order to use the language at competent intermediate to advanced level. I left out other features that aren't quite so essential—in my opinion. Some of my readers will disagree with my selections, but that can't be helped.

Special Edition Using JAVASCRIPT

By Mark C. Reynolds

Five years ago the Internet was mostly the province of academics and programmers, and the World Wide Web was an obscure idea in the minds of a few researchers. Today both are experiencing explosive growth and unparalleled interest. Web pages are being created at an astonishing rate. The fundamental challenge of Web page development is that while it is easy to create a Web page, it is more difficult to create an attractive and exciting one.

HTML, the markup language that describes the appearance of a page, is easy to learn, and requires no background in programming. HTML has undergone several revisions in order to meet the expanding needs of Web page authors. However, there are limits to what can be achieved inside HTML. The Java programming language was introduced to dramatically extend the Web developer's set of tools, but is still more complex than HTML. Java is very easy to learn; however, like most programming languages, it isn't easy to master. JavaScript bridges this gap.

JavaScript offers the Web page author a new level of sophistication without requiring him to become a programmer. JavaScript brings dynamic and powerful capabilities to Web pages, yet JavaScript is no more difficult to learn than HTML. JavaScript can be used to solve common problems, such as validating forms input, and can also be used to create dramatic and visually appealing content, which would be impossible with HTML. The goal of this book is to completely explore JavaScript, from the mundane to the extraordinary. It is designed as an introduction, a reference, and a continuous source of ideas, so that you may continually improve the Web pages that you create.

JavaScript Manual of Style

By Marc Johnson

This is a book about writing exciting Web pages with JavaScript. Before JavaScript or its ancestor, LiveScript, Web pages were written in HTML. The pages could be very sophisticated in their layout, but they just sat there. JavaScript can make your Web pages come alive. Your Web pages can now be dynamic, changing before the user's eyes. JavaScript can make your Web pages both more interesting and more fun.

JavaScript isn't very difficult to learn. I myself picked up the basics in a matter of hours. You can, too.

You don't need to read this book cover to cover, and you don't have to read the chapters in any particular order. Skip around, read what seems interesting, and write some code. It's the best way to learn. You will need a copy of Netscape Navigator, preferably version 2.01 or later, but that's all. I use WebMania! to write some of my code, because it takes care of a lot of the details that I might forget, but all you really need is a simple ASCII text editor-vi, emacs, Notepad, whatever.

This book is divided into three parts. The first part includes three chapters. Chapter 1is a quick introduction to JavaScript that describes what it is and where it came from. Chapter 2explains what JavaScript is good for, outlining what you can do with it. Chapter 3 lets me get up on my soapbox and do a little preaching about what makes a good Web page, what makes a bad Web page, and what you can do to keep your pages on the good list.

The second section consists of six chapters, all of which contain a complete JavaScript Web page. Each chapter introduces a problem, demonstrates how you might solve it without JavaScript, and then shows how you can craft a much better solution with JavaScript. These chapters all conclude with some thoughts on how you can enhance the solution and how you can adapt the techniques to creating your own Web pages with JavaScript. In every chapter, the JavaScript code is discussed in depth, function by function. No mysteries; there's no one behind the curtain. If you don't understand something about the code, write me at marcj@nando.net. I'll be glad to answer your questions!

Finally, the third section contains six appendices, chock full of useful reference material: the character set, reserved words, a review of HTML, the JavaScript operators, JavaScript's built-in objects and functions, and online resources. Again, if there's something I missed, write me. I want to help.

Voodoo’s Introduction to Javascript

By Stefan Koch

This tutorial is an introduction to JavaScript. I have started this tutorial as an online tutorial where you can test all examples immediately. As the tutorial grew larger a printable version was required.

What is JavaScript
JavaScript is a new scripting language which is being developed by Netscape. With JavaScript you can easily create interactive web-pages. This tutorial shows you what can be done with JavaScript - and more importantly how it is done.

JavaScript is not Java!

Many people believe that JavaScript is the same as Java because of the similar names. This is not true though. I think it would go too far at the moment to show you all the differences - so just memorize that JavaScript is not Java. For further information on this topic please read the introduction provided by Netscape or my book :-)

Introduction to JavaScript

The introduction to JavaScript explains you the basic of JavaScript web scripting. Following are the few topics covered in this JavaScript document.

What is JavaScript
Uses of JavaScript
Writing JavaScirpt
Programming Basics
Variables
Functions
JavaScript Objects
Objects
Properties
Methods
Document and Window Objects
Write to a Document
Open a Window
JavaScript Events
Events and Objects

JavaScript Origins

JavaScript was released by Netscape and Sun Microsystems in 1995. However, JavaScript is not the same thing as Java.

What is JavaScript

It is a programming language.
It is an interpreted language.
It is object-based programming.
It is widely used and supported
It is accessible to the beginner.

Uses of JavaScript

Use it to add multimedia elements: With JavaScript you can show, hide, change, resize images, and create image rollovers. You can create scrolling text across the status bar.

Create pages dynamically: Based on the user's choices, the date, or other external data, JavaScript can produce pages that are customized to the user.

Interact with the user: It can do some processing of forms and can validate user input when the user submits the form.

Sams Teach Yourself JavaScript in 24 Hours

By Michael Moncur

JavaScript is one of the easiest, most straightforward ways to enhance a Web site with interactivity.

Sams Teach Yourself JavaScript in 24 Hours serves as an easy-to-understand tutorial on both scripting basics and JavaScript itself ...

Introduction
The World Wide Web began as a simple repository for information, but it has grown into much more—it entertains, teaches, advertises, and communicates. As the Web has evolved, the tools have also evolved. Simple markup tools such as HTML have been joined by true programming languages—including JavaScript.

Now don't let the word "programming" scare you. For many, the term conjures up images of long nights staring at the screen, trying to remember which sequence of punctuation marks will produce the effect you need. (Don't get me wrong. Some of us enjoy that sort of thing.)

Although JavaScript is programming, it's a very simple language. As a matter of fact, if you haven't programmed before, it makes a great introduction to programming. It requires very little knowledge to start programming with JavaScript—you'll write your first program in Hour 2, "Creating a Simple Script."

If you can create a Web page with HTML, you can easily use JavaScript to improve a page. JavaScript programs can range from a single line to a full-scale application. In this book, you'll start with simple scripts, and proceed to complex applications, such as a card game.

If you've spent much time developing pages for the Web, you know that the Web is constantly changing, and it can be hard to keep up with the latest languages and tools. This book will help you add JavaScript to your Web development toolbox, and I think you'll enjoy learning it.

I really had fun writing this book—and believe it or not, writing isn't always fun. I hope you'll have as much fun as you experiment with JavaScript and its capabilities.

JavaScript Primer

So what is JavaScript? Is it Java? What does it do? Is it difficult to learn? These questions will all be answered in this tutorial, and more. Just to get us started, JavaScript is basically a scripting language that helps kick HTML into overdrive. With it, elements in a document can be programmatically accessed and manipulated, bringing a dull web page to life.

If you are content with using simply html to create web pages, you are ready to head out to our special tutorial , how to make fire with sticks; the rest of us, lets rock.

In this tutorial, we'll be looking at the following topics:

JavaScript Authoring Guide

The JavaScript Language
JavaScript is a compact, object-based scripting language for developing client and server Internet applications. Netscape Navigator 2.0 interprets JavaScript statements embedded directly in an HTML page, and LiveWire enables you to create server-based applications similar to common gateway interface (CGI) programs.

In a client application for Navigator, JavaScript statements embedded in an HTML page can recognize and 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, an HTML page with embedded JavaScript can interpret the entered text and alert the user with a message dialog if the input is invalid. Or you can use JavaScript to perform an action (such as play an audio file, execute an applet, or communicate with a plug-in) in response to the user opening or exiting a page.
