Video: What you should know before watching this course

JavaScript and AJAX is not a beginner course, and I'm starting with the assumption that there's a few things you already know before taking this course. So you should be familiar with building online projects and know how HTML works. A really good course to check out is James Williamson's HTML5: Structure, Syntax, and Semantics. You should also be familiar with basic JavaScript concepts. If you need help with that, check out Simon Allardice's JavaScript Essential Training. Now, one of the important things to understand about AJAX is that it is a conversation that happens between your server and your browser. Because of that, it means that these examples are not just going to work from your hard drive; you're going to need to have a server that your browser can talk to.

JavaScript and AJAX
1h 12m Intermediate Jan 18, 2013

Viewers: in countries Watching now:

The ability to read data and communicate information asynchronously is fundamental to modern web applications. In this course, author Ray Villalobos takes a look at integrating AJAX (Asynchronous JavaScript and XML) with JavaScript and jQuery—a combination that makes it easy to work with dynamic data and reduces the number of requests to the server. The course first explains what AJAX is, and shows how to load and reload pages with pure JavaScript, update the DOM, and read and parse data in the XML and JSON formats. Next, learn how to read and write information between the server and the client with AJAX methods in jQuery, and build a dynamic search application that updates search results as you type.

Topics include:
  • What is AJAX?
  • Making requests asynchronous
  • Updating the DOM with getElementById
  • Reading JSON files
  • Working with jQuery and AJAX
  • Sending and searching JSON data
  • Incorporating CSS transitions
Subjects:

What you should know before watching this course

JavaScript and AJAX is not a beginner course, and I'm starting with the assumption that there's a few things you already know before taking this course. So you should be familiar with building online projects and know how HTML works. A really good course to check out is James Williamson's HTML5: Structure, Syntax, and Semantics. You should also be familiar with basic JavaScript concepts. If you need help with that, check out Simon Allardice's JavaScript Essential Training. Now, one of the important things to understand about AJAX is that it is a conversation that happens between your server and your browser. Because of that, it means that these examples are not just going to work from your hard drive; you're going to need to have a server that your browser can talk to.

So for that you've got a couple of options. The simplest, and what we'll do on this course, is to work on a live server through FTP. If you need help understanding FTP and working with a hosted server, check out my course on Managing a Hosted Web Site. The other option is to run a local server on your machine. You can do that with software like MAMP on the Mac or WAMP on the PC. If you need help with that, check out Installing Apache, MySQL, and PHP, with David Gassner. Now, you should be familiar and comfortable working with text editors like BBEdit, Sublime Text, or others.

In this course I'm going to use an editor called Espresso, but you should use your favorite text editor. If you're on a Mac, you may want to check out TextWrangler from the Mac App Store. It has a cousin called BBEdit that is not free, but is a very capable developer tool. I like another editor that works on Macs, PCs, and Linux workstations called Sublime Text2. Although it's not free, it's quite capable and fun to use. And it really doesn't matter which editor you use, as long as it's something you're comfortable with. Finally, you're also going to need some sort of FTP application.

I'll be using Transmit from Panic on this course, but if you're on a Mac or a PC, you may want to check out Cyberduck, which is a free FTP program for Mac and Windows. So JavaScript and AJAX is not necessarily for beginners, but with just a little bit of background experience, you should have no problem with this course.

There are currently no FAQs about JavaScript and AJAX.
