Javascript string replace and regular expression

posted in JavaScript on 2013-06-15   word git replace string innerhtml text replace element innerhtml text changetext function word creator linus torvalds linux creator linus source project started

The replace method in JavaScript is pretty much the same as in the other languages. Replace part/s of a string with something else. However, there are some tricky moments and I wanted to write this article, because I met this problem several times in the past. Actually, very often I use my blog as a documentation for myself and this is one of those cases. Probably I'll be in the same situation after week or so and I'll just check here for the proper solution.

Chrome Extension: run JavaScript in the context of the current page

posted in JavaScript on 2013-06-14   script code document content run current page tab id code executescript tab id tabs executescript tab

I'm currently working on a Google Chrome extension and I need to run a JavaScript in the context of the current page. The obvious choice for such a logic is the content script. However it is not so easy, because the content script has an access only to the DOM of the current page. It can't run global functions or use global objects.

Flash, nodejs sockets and cross-domain policy file

posted in ActionScript on 2013-06-13   socket port xml policy file server anotherhost error flash player make

Ok, that was a long journey. I took an already build project and I had to make some changes. It's a complex system involving flex applications, nodejs and a mobile site. Before to start making changes I had to setup the project and make it work on my local machine. I spend few days doing this. At the end I successfully compile the flex application and made the necessary corrections. I uploaded the new swf file and of course it didn't work.

Convert HTML string to DOM element

posted in JavaScript on 2013-06-11   var markup output el link html frame contentdocument document createelement dom element

Checkout Revealing the magic: How to properly convert HTML string to a DOM element article.

I'm working on a chrome extension which accepts user text, work with it and output the result in a div. I used jQuery in the beginning, for several tasks, but later I decided to remove it and deal with pure javascript/DOM manipulations. The output div was filled by using innerHTML property and everything was ok. But, at some point, I sent few buttons to the user and he has to interact with them. However, once I update the div's content the event listeners are detached and the buttons became non-functional.

I believe that the ideas described in the material are important for our work as web designer and developers. David Walsh was really kind by publishing the article on his blog. You can find it here http://davidwalsh.name/design-responsively.

The Flash Builder debugger failed to connect to the running application.

posted in ActionScript on 2013-06-07   browser debug application flash player run device project time bin debug folder flash builder debugger

I really don't like FlashBuilder. Mainly because I'm losing a lot of time just to setup the project. Usually when I receive the files I need around 10 hours just to compile successfully. The reasons for those problems are different Flex SDK, different directories' tree, wrong paths, missing libraries or fonts. Today I encounter a brand new type of problem.
