AngularJS Directives Cookbook

Overview of this book

AngularJS directives are at the center of what makes it such an exciting – and important - web development framework. With directives, you can take greater control over HTML elements on your web pages – they ‘direct’ Angular’s HTML compiler to behave in the way you want it to. It makes building modern web applications a much more expressive experience, and allows you to focus more closely on improving the way that user interaction impacts the DOM and the way your app manages data. If you’re already using Angular, you probably recognize the power of directives to transform the way you understand and build your projects – but customizing and creating your own directives to harness AngularJS to its full potential can be more challenging. This cookbook shows you how to do just that – it’s a valuable resource that demonstrates how to use directives at every stage in the workflow. Packed with an extensive range of solutions and tips that AngularJS developers shouldn’t do without, you’ll find out how to make the most of directives. You’ll find recipes demonstrating how to build a number of different user interface components with directives, so you can take complete control over how users interact with your application. You’ll also learn how directives can simplify the way you work by creating reusable directives – by customizing them with Yeoman you can be confident that you’re application has the robust architecture that forms the bedrock of the best user experiences. You’ll also find recipes that will help you learn how to unit test directives, so you can be confident in the reliability and performance of your application. Whether you’re looking for guidance to dive deeper into AngularJS directives, or you want a reliable resource, relevant to today’s web development challenges, AngularJS Directives Cookbook delivers everything you need in an easily accessible way.

A simple directive example


AngularJS has its own version of jQuery, known as jQuery Lite. This version has just over 30 methods, some of them a little limited, as is the case with find(), parent(), and on(), among others. AngularJS added some extra methods to the jQuery Lite version such as $destroy(), injector(), and inheritedData(), which is the same as $data(). Along with many others.

Another important thing to note is that the $ dollar sign has no effect here. The AngularJS equivalent is angular.element, so something like this:

angular.element() === jQuery() === $()

In most cases, it is sufficient to use the built-in version of jQuery on AngularJS; however, if you require any method that is not listed in the official documentation, you can include the full version of jQuery in your HTML file, always put before the AngularJS script.

Getting ready

In this chapter, we will also use the generator-angm, as we did in the previous chapter.

This time we will call our application jquerydirectives....
