Overview of this book

If you want to improve responsiveness or the UX in your ASP.NET applications, JavaScript can be a life saver. In an age where server-side operations have shifted to the client, being able to handle JavaScript with confidence and fluency is vital for ASP.NET developers. There’s no point trying to fight it, so start learning with this book. Make sure your projects exceed user expectations. Begin by getting stuck into the basics of JavaScript, and explore the language in the context of ASP.NET Core. You’ll then find out how to put the principles into practice, as you learn how to develop a basic ASP.NET application using Angular 2 and TypeScript. You’ll also develop essential skills required to develop responsive apps, with a little help from AJAX, ensuring that you’re building projects that can be easily accessed across different devices. With guidance on Node.js and some neat techniques to test and debug a range of JavaScript libraries in Visual Studio, you’ll soon be well on your way to combining JavaScript with ASP.NET in a way that’s capable of meeting the challenges of modern web development head-on.

Getting started with jQuery


The jQuery library can be downloaded from http://jquery.com. The latest version of jQuery is 3.0.0 and you can use this library if you are targeting modern browsers; for example, IE 9 and Microsoft Edge support this version. For older versions—for example, IE 6-8—you can download jQuery 1.x.

Once jQuery is downloaded, you can add it to your project and reference it, as shown here:

<head>
  <script src="~/scripts/jquery.js"></script>
</head>
<body>
</body>

Using a content delivery network

Instead of loading jQuery from your server, we can also load it from some other server, such as the Microsoft server or Google server. These servers are called the content delivery network (CDN) and they can be referenced as shown here:

  • Referencing the Microsoft CDN:

    <script src="http://ajax.microsoft.com/ajax/jquery/jquery-2.0.js">
    </script>
  • Referencing the Google CDN:

    <script src="http://ajax.googleapis.com/ajax/libs/jquery/2.0/jquery...
