Javascript 2nd edition book free
You are about to begin a journey through JavaScript— a programming language that adds interactivity and spark to web pages all over the Internet. This book, written primarily for nonprogrammers, provides scripts you can cut and paste for use on your website, but it also explains how they work, so you’ll soon be writing your own scripts. Each chapter focuses on a few important JavaScript features, shows you how professional websites incorporate those features, and gives you examples of how you might add those features to your own web pages.


 Chapter 1: Welcome to JavaScript!
This chapter lays out the book’s goals, introduces you to JavaScript and compares it to other tools, describes some of the nifty ways in which JavaScript can enhance your web pages, and walks you through writing your first JavaScript.
Chapter 2: Using Variables and Built-in Functions to Update Your Web Pages
Automatically

Did you know that JavaScript can figure out what day it is and write the date to a web page? This chapter will show you how. Along the way you’ll also learn how JavaScript remembers things using variables and performs actions using functions.
Chapter 3: Giving the Browsers What They Want
In this chapter you’ll learn how to direct someone to a web page specifically designed for his or her browser. You’ll figure out which browser the visitor is using, then you’ll use if-then statements and their kin to point the visitor in the right direction.
Chapter 4: Working with Rollovers
This chapter covers everyone’s favorite JavaScript trick—the image swap. You’ll also learn how to trigger JavaScript based on a viewer’s actions.
Chapter 5: Opening and Manipulating Windows
This chapter explains everything you need to know about opening new browser windows—another favorite JavaScript trick. You’ll also learn how JavaScript writes HTML to the new windows, closes them, and moves them around on the screen.
Chapter 6: Writing Your Own JavaScript Functions
Functions are the major building blocks of any JavaScript program, so learning to write your own is a critical step toward JavaScript mastery. This chapter gives you the tools you’ll need to write your own functions and put them to work.
Chapter 7: Providing and Receiving Information with Forms
This chapter shows you how JavaScript works with HTML forms to collect all kinds of information from your users and give them fancy ways to navigate your site.
Chapter 8: Keeping Track of Information with Arrays and Loops
JavaScript calls lists arrays, and they come in very handy. This chapter describes how JavaScript deals with these lists, whether they include all the images on a web page or all the friends in your address book.
Chapter 9: Timing Events
This chapter discusses setting events to occur at specific times. For example, you can open a window and then close it in five seconds, or you can write a clock that updates every second. Once you know how to do this, you can create games and other interactive applications based on timed events.
Chapter 10: Using Frames and Image Maps
How JavaScript works with HTML frames and image maps is the subject of this chapter. It covers topics including changing two or more frames at once and preventing your web page from getting trapped in someone else’s frame set.
Chapter 11: Validating Forms, Massaging Strings, and Working with Server-Side
Programs

This chapter shows you how to make sure people are filling out your HTML forms completely. Along the way, you’ll learn fancy ways to check user input—for example, you’ll learn how to check the formatting of an email address.
Chapter 12: Saving Visitor Information with Cookies
Cookies are bits of code that let your web pages save information a visitor has provided even after he or she turns off the computer. This allows your site to greet a guest by name whenever he visits (if he tells you his
name, of course!).
Chapter 13: Dynamic HTML
This chapter introduces Dynamic HTML, a feature of newer browsers that lets you animate entire web pages.
Chapter 14: Ajax Basics
This chapter begins a trilogy of chapters on Ajax, a programming technique that helps you build websites that act like desktop applications. Here you’ll be introduced to Ajax and most of the JavaScript you’ll need to know to create Ajax applications.
Chapter 15: XML in JavaScript and Ajax
The X in Ajax stands for XML. This chapter describes how to represent information using the XML data-sharing standard and process XML documents using JavaScript.
Chapter 16: Server-Side Ajax
You’ll wrap up your introduction to Ajax with instructions for writing programs that run on webservers. This chapter touches on the PHP programming language and shows you how PHP programs store files on webservers and contact other webservers for information.
Chapter 17: Putting It All Together in a Shared To Do List
In this chapter you’ll apply everything you learned in the first 16 chapters and create a collaborative To Do list application. Not much new material will be introduced, but you’ll see how everything we’ve covered
so far fits together.
Chapter 18: Debugging JavaScript and Ajax
This chapter wraps things up by giving you tips for what to do when the JavaScript you’ve written isn’t working correctly.
