Javascript: handling keyboard shortcuts with jQuery

posted in JavaScript on 2011-01-19 ctrl shift f9 document log key jquery

Last few years the JavaScript frameworks are big part of our web sites. I strongly recommend the usage of tools like jQuery or MooTools, because they will save you a lot of time and problems. These days I needed to create a keyboard shortcut for one of the projects that I'm working on. I wanted to catch the Ctrl+Shift+F9 combination. It was just a few lines of code and I decided to share it with you.

Javascript: handling with crossdomain requests

Ajax is a powerful tool for loading new content or data asynchronously. The well known problem is that we can't make requests to other hosts. In other words if your code is located at aaa.com you can't load bbb.com/getData.php. There are several solutions available.

As a huge fen of the flash platform, I always like to work with events. The events system in ActionScript3 is really helpful when we are building a big application with many modules and we want to keep them independent. JavaScript hasn't native support of events, but we can still use them.

Currently I'm working on a big JavaScript project. It has a lot of files that have to be compressed. I wrote a simple php class that merges all the files into one. It has also a useful simple obfuscator method.

AS3: Using custom Metadata in Flex (part 1)

posted in ActionScript on 2010-12-28 metadata public flex mycustomclass information metadata tags tag as3 flash utils describetype public function mycustomclass

I'm sure that you've already used metadata tags in your flex applications. There are several reserved keywords like [Bindable], [Embed], [Event] and so on (the full list is available here). The function of the metadata tags is to provide additional information to the flex compiler. For example information about embeding assets, dispatching events. This article doesn't explain how to use the default flex tags (you can learn that from here). It shows you how to create your own metadata tags and how to use them.
