This task-based, visual-reference guide has been fully revised and uses step-by-step instructions and plenty of screenshots to give beginning and intermediate scripters what they need to know to keep their skills up-to-date. Readers can start from the beginning to get a tour of the programming language, or look up specific tasks to learn just what they need to know. In this updated eighth edition, readers will find new information on using frameworks and libraries--such as jQuery--and modern coding techniques.
Want to create websites that deliver the fast response times, dynamic user interfaces, and special effects that today's users expect?
Then this is the book for you! Whether you're just starting out in JavaScript or whether you're ready to move into DOM scripting, it gives you the skills you need. Here's how:
#1: It's 2 books in 1: A JavaScript book and a DOM scripting book Most books cover JavaScript or DOM scripting. But to create user-responsive sites, you need to know both.
So the first half of this book is a course in JavaScript essentials. Then, the second half is a course in DOM scripting that gives you a clear understanding of how DOM scripting works, how JavaScript underlies it, and how to use it to build applications that run slide shows, use drop-down menus, rotate headlines, sort tables, provide animation, and more!
That means you can gain basic to expert skills in a single book.
#2: It provides a fast start Section 1 is a crash course in JavaScript. In fact, by the end of chapter 3, you'll know how to code, test, and debug applications that include elementary DOM scripting. Then, the rest of the book builds on those skills to cover all the JavaScript and DOM scripting essentials.
#3: It shows you how to create and use event-handling libraries for browser compatibility One of the headaches of web programming is ensuring that the code will work with all the popular browsers.
So this book shows you how to create your own event-handling libraries of browser-compatible code, so you can draw on it as needed. It shows you how to take advantage of free, third-party libraries like jQuery and Dojo. And it helps you to appreciate, and profit from, the extensive libraries of tested code that are included in the downloadable applications for the book.
#4: It shows 20 complete applications that can be used as models for new apps The key to mastering client-side web development is to have plenty of applications that show how the features interact and what problems might occur in building a website.
So this book gives you complete code for 20 professional applications. These run the gamut from business applications, like object-oriented forms validation, to entertainment apps, like a rotating, 3-dimensional carousel of images that the user can control with the mouse or keystrokes.
You can download these for free from the Murach website. Experiment with them on your own, then use them as time-saving models for new applications.
#5: The paired-pages format lets developers set their own pace Murach books have a distinctive format. Each two-page spread presents a single topic: the lefthand page explains the topic, while the righthand page shows the critical details, using syntax, code, screen shots, and how-to notes.
Both beginning and experienced developers tell us that this format makes it easy to focus on the information they need, whether they're using the book for training or reference. Again, you can try this out for yourself by downloading chapters 2 and 3 for free from the Murach website.
So don't wait to become an expert web developer. Get your copy of Murach's JavaScript and DOM Scripting today!

Editorial Review :
Of all the Ajax-specific frameworks that have popped up in recent years, one clearly stands out as the industrial strength solution. Dojo is not just another JavaScript toolkit -- it's the JavaScript toolkit -- and Dojo: The Definitive Guide demonstrates how to tame Dojo's extensive library of utilities so that you can build rich and responsive web applications like never before. Dojo founder Alex Russell gives a foreword that explains the "why" of Dojo and of this book.
Dojo provides an end-to-end solution for development in the browser, including everything from the core JavaScript library and turnkey widgets to build tools and a testing framework. Its vibrant open source community keeps adding to Dojo's arsenal, and this book provides an ideal companion to Dojo's official documentation.
Dojo: the Definitive Guide gives you the most thorough overview of this toolkit available, showing you everything from how to create complex layouts and form controls closely resembling those found in the most advanced desktop applications with stock widgets, to advanced JavaScript idioms to AJAX and advanced communication transports. With this definitive reference you get:
Get a concise introduction to Dojo that's good for all 1.x versions
Well-explained examples, with scores of tested code samples, that let you see Dojo in action
A comprehensive reference to Dojo's standard JavaScript library (including fundamental utilities in Base, Dojo's tiny but powerful kernel) that you'll wonder how you ever lived without
An extensive look at additional Core features, such as animations, drag-and-drop, back-button handling, animations like wipe and slide, and more
Exhaustive coverage of out-of-the-box Dijits (Dojo widgets) as well as definitive coverage on how to create your own, either from scratch or building on existing ones
An itemized inventory of DojoX subprojects, the build tools, and the DOH, Dojo's unit-testing framework that you can use with Dojo -- or anywhere else
If you're a DHTML-toting web developer, you need to read this book -- whether you're a one-person operation or part of an organization employing scores of developers. Dojo packs the standard JavaScript library you've always wanted, and Dojo: The Definitive Guide helps you transform your ideas into working applications quickly by leveraging design concepts you already know.
Question : How to fix javascript errors in my windows vista computer?
My pc has javascript error message pops up. My OS is vista. Can u kindly tell me how to fix in in plain English?
Answer:
There are mainly two reasons:1. If you are getting JavaScript error when using a certain program then you can try to update the program and check if the problem is solved, or u can reinstall the program.2. If you are experiencing errors from webpage you can check if Active script, Java applets, or ActiveX is blocked on your browser settings. Check other computer if they are getting Javascript error when opening that website. If yes then the problem lays on the website itself, not your computer.If none of these solutions work, then you have a problem in your system files or registry. Registry cleaner program will scan all errors in your computer and repair them. They will eliminate all possible causes of bugs and errors. Registry easy is the best cleaner among those cleaner. U can easily fix all errors in ur pc like a pc guru:)

Question : How can I call a Javascript event on a HTML div border corners?
It sounds confusing, but is quite simple. I have a square div, and using css I have four circles replacing the corners of the of the divs border. I want the user to be able to click on one of the corner circles changing the curser image and calling the Javascript onclick event. How do I did that?
Answer:
The corners of the div are not in themselves elements that you can give attributes to (other than the border color and width). But do simulate this you can easily making a div superimposed on a larger div, thus making it seem as if the back div is it's border.

Question : How can JavaScript be used to display things differently in two different browsers?
Hey everyone, I started programming and was wondering how JavaScript can be used to display things differently in two different browsers? Thanks for all help!Sorry, I mean like explain to me? I understand the code but what are the different ways in which Javascript can be used to display things differently in two different browsers? Thanks!
Answer:
Use this to have all details of the browser in use:(Put "document.write ( " sign for BR " );" between each for clarity.)Use any of these variables to decide what to do...UA (User agent) is the name of the browser (a long string)Get the screen width (resolution)function GetW ( ){var myWidth = 0;if( typeof( window.innerWidth ) == 'number' ) //Non-IEmyWidth = window.innerWidth;else if ( document . documentElement && ( document . documentElement . clientWidth || document . documentElement . clientHeight ) ) {//IE 6+ in 'standards compliant mode'myWidth = document . documentElement . clientWidth;}else if ( document.body &&( document . body . clientWidth || document . body . clientHeight ) ) {//IE 4 compatiblemyWidth = document.body.clientWidth;}return (myWidth);}(spaces and CR added for clarity and YA line cutter!)
Question : How do I fix a javascript error on page?
I cannot open any emails due to a javascript error. If it helps, We recently switched internet providers from rogers to bell. Does anyone know how to fix this?
Answer:
Now please provide more information on the browsers you use.You can disable javascript error pop ups both in IE and mozilla. But if the javascript is totally crap that the page cannot run, you have to wait till the web site administrator corrects it.
Question : How do you fix JavaScript errors using debugger/developer tools, in interent explorer?
As of two days ago I can no longer attach things or send emails using my university email account with internet explorer because of JavaScript errors. I think it is a runtime error?! Anyway, I kow how to open the debugger from selecting it from the tools menu in IE and it does detect problems with this website, but I have no idea what I need to do with the debugger to fix them. Can you please help. Thanks.It is meant for anyone to use. Look at developer tools in the dropdown menu of tools. It isn't an ie problem, its my pc which I can fix.
Answer:
I don't know what debugger you are talking about, but I'm pretty shure the tool is meant for developers, not users.Aks the administrator to fix it, and until then, you can't do much but use another browser.
Question : How do I code a text that shows up only if Javascript isn't enabled in the browser?
What is the code to display text only when the user doesn't have javascript enabled (so it would say "you need javascript enabled to view this) but doesn't show up when javascript IS enabled, just running the script? I hope that makes sense. Thanks!
