Overview of this book

If you are a web developer and want to create web applications that look good, are efficient, have rich user interfaces, and integrate seamlessly with any backend using AJAX, then this book is the ideal match for you. We’ll show you how you can integrate jQuery 3.0 into your web pages, avoid complex JavaScript code, create brilliant animation effects for your web applications, and create a flawless app. We start by configuring and customising the jQuery environment, and getting hands-on with DOM manipulation. Next, we’ll explore event handling advanced animations, creating optimised user interfaces, and building useful third-party plugins. Also, we'll learn how to integrate jQuery with your favourite back-end framework. Moving on, we’ll learn how the ECMAScript 6 features affect your web development process with jQuery. we’ll discover how to use the newly introduced JavaScript promises and the new animation API in jQuery 3.0 in great detail, along with sample code and examples. By the end of the book, you will be able to successfully create a fully featured and efficient single page web application and leverage all the new features of jQuery 3.0 effectively.

Copying elements


So far in this chapter, we have inserted newly created elements, moved elements from one location in the document to another, and wrapped new elements around existing ones. Sometimes, though, we may want to copy elements. For example, a navigation menu that appears in the page's header could be copied and placed in the footer as well. Whenever elements can be copied to enhance a page visually, we can let jQuery do the heavy lifting.

For copying elements, jQuery's .clone() method is just what we need; it takes any set of matched elements and creates a copy of them for later use. As in the case of the $() function's element creation process we explored earlier in this chapter, the copied elements will not appear in the document until we apply one of the insertion methods.

For example, the following line creates a copy of the first paragraph inside <div class="chapter">:

$('div.chapter p:eq(0)').clone(); 

This alone is not enough to change the content of the page. We can...
