In part 1 I showed how to add a swipe effect to a scrolling area using only the new CSS properties in IE10. I also added some JavaScript to create the same effect in other touch-supported browsers like iOS.

The CSS stuff in IE10 is great, but there is only so much you can do with it. If we want a completely custom effect we need to get involved with IE10’s touchscreen event model. Things get a bit more complicated now…

This demo uses JavaScript in IE10 to achieve the same swiping effect as the CSS solution in part 1. However, if you swipe harder you will move three places instead of one. This way you can essentially flick an item from one end to the other. Not the greatest effect in the world, it’s just an example.

I just finished working on the Lovie Awards Winners Gallery. As a result of the Microsoft partnership I learned quite a bit about touchscreen support in IE10. Part of the site has progressively enhanced sideways scrolling areas which are swipeable on touch screens. I’ve put together a few demos here to show what we ended up doing and highlight some of the gotchas.

AMF and RTMP libraries for node.js – Flash remoting with node.

I’ve been having fun playing with node.js over the past year, but have had little, or no excuse to use it in any production work, so I thought I’d set myself a challenge and build a module. That challenge was firstly to create a simple AMF gateway for Flash remoting, and secondarily to see if an RTMP socket server was achievable in node.

If you don’t know about “node” – It’s a JavaScript runtime that allows you to write socket servers. I like it a lot – it brings asynchronous, event-driven programming to the server side and provides a truly global variable scope across all connections. I’ll blog about it in more detail later, perhaps.

At Public we do a lot of Flash work, and regularly implement Flash remoting using a PHP AMF gateway. I wasn’t necessarily looking to replace this stock approach with node, but node offers proper socket connections that PHP can’t, so I was imagining the possibilities of using node as a free, and more flexible alternative to Flash Media Server. Not for streaming media, but for real-time messaging, for example in multi-player games. If I’m honest though, I did this mostly for fun, an academic exercise and as an excuse to work with node.

After nearly two years I’ve finally gotten around to releasing my PHP JavaScript parser, although documentation is still thin on the ground.

The library has been split in two:

  1. jTokenizer – A JavaScript tokenizer designed to mimic the PHP tokenizer.
  2. jParser – The fully blown JavaScript syntactical parser which generates a parse tree.

After a brief exchange of tweets with @jsmag I discover this web development ‘podcast’ : webdevgeekly.com, which appears to be run by the same people as jsmag.com. About 9 minutes into the following podcast there is a 2 minute discussion about JASPA. Conveniently just 24 hours after I rescued my site from a hardware crash.

I’ve received quite a few emails recently asking me where the code is for jParser.

I’ve had to disappoint so far, because it’s not currently available for download. My web analytics also tells me that a lot of people are finding this blog by Googling “php javascript parser“. There’s clearly a need out there, so I’d better do something about it.

I know why I want a JavaScript parser, but what kind of things might you need it for? What API features/functions would you like to see? Please post a comment and let me know. Watch this space for a release, and in the mean time here’s some food for thought …
