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.

Using the data attribute to HTML5 compile

The data attribute is an important and powerful feature of HTML5. It helps us to have more control over the HTML of our application, and this is not different on AngularJS applications.

Imagine that you are working on an AngularJS application and need to validate your HTML with a validating tool. Many companies require that you ensure your HTML code is valid, by quality questions or web standards, and others simply use it as a selling point for future customers.

If you try to validate an AngularJS application, it will have some or many errors related to the ng- tags. To avoid this, we must use the following solution.

Getting ready

Let's use the same navbar HTML code from the previous example to show the use of the data attribute.

How to do it…

  1. Just apply the data- attribute before all the ng- tags:

    <div class="navbar navbar-default">
      <div class="container">	
        <ul class="nav navbar-nav">
          <li data-ng-class="{active:isActive...
