Get and Set HTML5 Video Current Time
Last week I explored how you could get the duration of a HTML5 video. It's an important technique, obviously, but one that may be a bit more important is managing the video's time setting. Both setting and getting the video's time is important when creating a chrome around the video, so let's review how to accomplish this feat.
The first and probably most important part of managing video time state is knowing that video currentTime is the important attribute. You can retrieve the video's current time with the following:
// https://www.youtube.com/watch?v=Cwkej79U3ek
console.log(video.currentTime); // 25.431747
currentTime acts as both a getter and a setter, so you can move about the video by setting a value to currentTime:
video.currentTime = 0; // Restart
The API is easy enough and the property is self-explanatory. You'll still need to do the "second" math to interpret the time, both inward and outward, but the second unit is as fair as you could expect, so this API is one to be appreciated.

Feature detection via JavaScript is a client side best practice and for all the right reasons, but unfortunately that same functionality hasn't been available within CSS. What we end up doing is repeating the same properties multiple times with each browser prefix. Yuck. Another thing we...

Let's be honest, form validation with JavaScript can be a real bitch. On a real basic level, however, it's not that bad. HTML5 has jumped in to some extent, providing a few attributes to allow us to mark fields as required or only valid if matching...
![Do / Undo Functionality with MooTools]()
We all know that do/undo functionality is a God send for word processing apps. I've used those terms so often that I think of JavaScript actions in terms of "do" an "undo." I've put together a proof of concept Do/Undo class with MooTools.

Yeah, it would be nice if it worked as expected.
On mobile browsers i.e., any glitch in network/video makes video stop while currentTime property continues advancing, making it unusable and unreliable unless countless per-browser workarounds are set.
Also changing orientation makes video pause, while currentTime continues running losing any reliability.
Too bad. All those html5 tags are fantastic on paper, in reality they are unusable, unless wasting hours fixing per-browser/device bugs and uniquenesses.
