Whether you need to learn JavaScript from scratch or just want a refresher, Learning JavaScript provides an easy path through Java Scripts power and idiosyncrasies.

JavaScript has exploded into prominence again as a key part of Ajax, giving web sites more intelligence and more useful interactions with their visitors. JavaScript has also spread to realms of programming beyond the Web, providing a convenient scripting language for other software.

The web-based examples in this book demonstrate how to build JavaScript logic and connect it to existing object structures, as well as how to build your own libraries and take advantage of libraries other users have written.

Learning JavaScript explores:

Basic JavaScript logic, from functions and operators to control structures.
Techniques for using JavaScript reliably in the multibrowser world of the Web.
Java Scripts extensibility mechanisms and how they differ from traditional object-oriented programming.
Handling traditional JavaScript tasks, such as form validation, DOM manipulation and interactive styling.
JavaScript security, including the web-browser sandbox, cookies and interaction with other objects.
Creating object libraries for handling common tasks.
Building Ajax applications with JavaScript and the XML-Http-Request object.
Applying libraries for special effects and Ajax interactions.

Whether you're a web designer who has used bits of JavaScript for years, a programmer who needs to learn JavaScript or someone new to development who just wants to make something work on the Web, Learning JavaScript will explain how to apply this powerful scripting language to the challenges you face today.
