PBS 76 of X — AJAX with jQuery
Filed Under Computers & Tech, Software Development on April 20, 2019 | 2 Comments
Having laid a very strong foundation in the previous instalment, we’re now ready to learn how to make HTTP requests with JavaScript using a technique known as AJAX.
We’ll start our journey into AJAX using more traditional JavaScript techniques, i.e. we’ll use callbacks to handle HTTP responses. As we’ll discover, this works very well for single AJAX requests, but the model really starts to get complicated when you have multiple inter-dependent requests. We won’t complicate things in this instalment though — we’ll start with just simple stand-alone requests this time.

PBS 75 of X — AJAX Intro
Filed Under Computers & Tech, Software Development on April 6, 2019 | 1 Comment
Having wrapped up our introduction to Mustache templates we’re going to spend the next few instalments learning about AJAX, a very powerful JavaScript technique for loading information from a given URL. In future instalments we’ll use this technique to load external templates and data for use with our Mustache templates.
AJAX is a mechanism for making a HTTP requests via JavaScript, so before we’re ready to learn about AJAX we need to take the time to learn about the HTTP protocol itself. Unless you understand the mechanics and the terminology of HTTP, AJAX-related documentation simply won’t make any sense.
