JSON is a popular way to format AJAX responses, as it’s more compact than XML and essentially a JavaScript object, but it can be a real pain to work with due to uncooperative browsers. It’s easy enough to view XML in a web browser, which is good for testing, but JSON responses cause a download prompt to open. This makes it harder to verify that an AJAX request is working properly.
Fortunately, a clever developer has built a Firefox extension to solve this problem. JSONView renders a plain-text representation of the JSON object, complete with indentation and color-coding whenever you access a URL that outputs JSON data. For example, the Twitter API. If you click this link in Firefox, you will be prompted to download the file. With JSONView installed, you would see output from the following image.
If you do much JavaScript work, be sure to install JSONView. It will save you some headaches when you have AJAX requests that aren’t working quite right.

Have you ever wanted to link to an iTunes page? It’s easy enough to copy a long, nasty-looking URL like http://itunes.apple.com/us/album/yours-truly/id310905907 right from the application by right-clicking on the album art or title. This works well enough if you’re manually linking to an album…

Many modern web browsers have early support for the <video> and <audio> elements in the HTML5 spec. Unfortunately, their implementation varies depending on the ideals of the various browser developers. Safari expects video to be encoded in the high-quality H.264 codec, other browsers prefer…

If you go to a social networking site like Twitter, you’ll note that status updates don’t have conventional timestamps on them. Instead of something overly informative (in most cases) like “Posted 2010/07/06 7:50 PM” they tend to show the much more human-friendly “Posted 2…

Here’s a fun (and slightly puzzling) fact: CSS selectors are parsed from right-to-left instead of from left-to-right when the browser renders a page. This means that when you have a selector like .navigation a { color: red; }, the browser first searches for a…

It’s always fun to obtain data from REST APIs and parse the XML or JSON response. Twitter, for sure, wouldn’t be what it is today if not for the thriving community of developers building applications that tie-in with the API. But what do you…
