Foreword

After exiting the printing of the book fourth edition JavaScript . Detailed handle duction "Document Object Model ( the Document Obj ect Model , the DOM ), representation amounts to the basis of an application programming interface ( the Application Pro gramming Interface , the API ) for the scripting language JavaScript , running on the client side has been implemented adequately, if not completely, in web browsers. This means that developers of web applications have at their disposal a universal API for working with the content of web pages on the client side and a mature language ( JavaScript 1.5), which remained stable over the following years.

Now interest in JavaScript is starting to grow again. Now developers Execu form a JavaScript to create scripts, working on the protocol the HTTP , control XML -data and even dynamically create image iso mapping in a web browser . Many programmers using JavaScript create great programs and are used quite sophisticated technology, the solution tion, such as FAULT Ia and namespaces. The fifth edition is completely revised from the perspective of the newly emerging technologies Ajax and We b 2.0.
