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.

Directive's controller function

In this chapter, we have seen a different way to declare a directive to manipulate the DOM. In the previous chapter, we explored different ways of working with the directive's properties. In this example, we will declare an external controller to the directive without writing any code within the directive.

Getting ready

Using external controllers is very common in applications that have many customized directives. They help us separate the content in a more practical way, in the same behavior of the directives template. With separated controllers, we can use many AngularJS resources, such as services and other features.

This example serves to illustrate the flexibility that directives have.

We will use the same code as the previous example, but this time, we will place the controller's code in a separate file.

How to do it…

  1. Replace the controller's code with the following highlighted code:
    'use strict';
    
    /**
     * @ngdoc function...
