skyfire

June 8th, 2009 . by Sajeev

This is really happy news of flash/flex developers. Skyfire says it can play both Flash 10 and Silverlight 2.0. Not sure how happy Adobe will be though, they’ve always resisted full Flash on mobile for “performance” reasons.

check for more details..

Project Natal, fully hands-free control system

June 3rd, 2009 . by Sajeev

This is some pretty impressive interactive technology:

Project Natal

Mr Spielberg said he had always stated that "the main barrier stopping people getting into video games was the complexity of a games controller," and that Natal was "a whole new world".

This is really true, I am not at all interested in playing game because of the same reason. And this technology seems to be really impressive. Hope to experience this in near future.

window.setTimeout to JavaScript.doLater

April 6th, 2009 . by Sajeev

Check the syntax for window.setTimeout for mozilla and IE, u can see that it is different in both the browzor. Below is the one method, which will help in unifying this for both browzors.

Syntax
timeoutID = JavaScript.doLater(thisArg, func, delay, [, arg1[, arg2[, ...]]]);

PLAIN TEXT
JavaScript:
  1. JavaScript = {
  2.      /*
  3.      * queue for later call
  4.      * target - target type object where method exist
  5.      * method - method to execute after delay milliseconds
  6.      * delay - is the number of milliseconds that the function call should be delayed by (default 0)
  7.      * use - JavaScript.doLater(this, method);
  8.      */
  9.     doLater : function(target, method, delay)
  10.     {
  11.         delay = delay || 0;
  12.         var parameters = (Browzor.IE) ? [target, method] : [JavaScript.createProxy(target, method), delay];
  13.         for(var i = 3; i <arguments.length; i++) {
  14.             parameters.push(arguments[i]);
  15.         } 
  16.         if(Browzor.IE) return window.setTimeout(JavaScript.createProxy.apply(JavaScript, parameters), delay);
  17.         else return window.setTimeout.apply(window, parameters);

Igonre Whitespace in the DOM

December 16th, 2008 . by Sajeev

The presence of whitespace in DOM will become a problem in Mozilla. This will occurs in cases like, when u create html in server side like jsp and injecting the output as string into DOM node. IE will automatically ignore all the whitespace but not Mozilla!. This method can do this for you.

PLAIN TEXT
JavaScript:
  1. function ignoreWhiteSpace(stringXml) {
  2.     if(typeof stringXml != 'string')return;   
  3.     stringXml = stringXml.trim("\\t\\n\\r\\s");
  4.     stringXml = stringXml.replace(/<!--[\S\s]*?-->/g,"");       
  5.     /*
  6.      * \s includes non-breaking spaces (and also some other characters).
  7.      */
  8.      //stringXml = stringXml.replace(/>[\t\n\r\x20]+</g,"><"); 
  9.     stringXml = stringXml.replace(/>[\t\n\r\x20]*(.*?)[\t\n\r\x20]*</g,">$1<"); 
  10.     return stringXml;   
  11. }
