Using the Microsoft Ajax Minifier to reduce the size of any JavaScript file
The Microsoft Ajax Minifier enables you to reduce the size of a JavaScript file by removing unnecessary content from the JavaScript file. The tool supports two modes: normal crunching and hypercrunching.
When you use normal crunching, the Microsoft Ajax Minifier strips all comments, unnecessary whitespace, curly-braces, and semicolons from a JavaScript file. Surprisingly, just removing all of this unnecessary code fluff can make a significant difference to the size of a JavaScript file.
When you use hypercrunching, the Microsoft Ajax Minifer gets more aggressive about reducing the size of a JavaScript file. In hpercrunching mode, the Microsoft Ajax Minifier shortens the names of local variables (variables in functions but not global variables) and it removes unreachable code.
The article also shows how to use the Microsoft Ajax Minifier from the Command-Line and how to integrate the Microsoft Ajax Minifier directly into the Visual Studio build process.

How to use the YouTube embedded Video Player
YouTube Chromeless Player API
Chromeless player SWF URL:
http://gdata.youtube.com/apiplayer?key=DEV_KEY
note: it is using gdata.youtube.com and videoId is no longer part of the url as it was used in the javascript player api.
Functions
The following functions are available in addition to the ones listed in the JavaScript API section below:
loadVideoById(videoId:String, startSeconds:Number):Void
cueVideoById(videoId:String, startSeconds:Number):Void
setSize(width:Number, height:Number):Void
Sample Code: http://code.google.com/apis/youtube/chromeless_player_reference.html#ExamplesYouTube JavaScript Player API
Embedding the YouTube player using SWFObject
We recommend using SWFObject to embed any players that will be accessed using the JavaScript API. This will allow you to detect the end user’s Flash Player version (the JavaScript API requires Flash Player 8 or higher), and also will get rid of the ‘Click to activate this control’ box when using Internet Explorer to view the player. To enabled the API in the SWF, you must pass in the parameter
enablejsapi=1.Additional SWF Url Parameters that allows you to set things like color, border, autoplay, ‘Genie’ menu, related videos etc…
Getting the Player Reference
e.g. function onYouTubePlayerReady(playerId) { ytplayer = document.getElementById(“myytplayer”); }
Issuing Calls
e.g. function play() { if (ytplayer) { ytplayer.playVideo(); } } <a href=”javascript:void(0);” onclick=”play();”>Play</a>
Subscribing to Events
e.g.
function onYouTubePlayerReady(playerId) { ytplayer = document.getElementById(“myytplayer”); ytplayer.addEventListener(“onStateChange”, “onytplayerStateChange”); }
function onytplayerStateChange(newState) { alert(“Player’s new state: ” + newState); }

How to embed Flash Player content using SWFObject dynamic publishing
STEP 1: Create alternative content using standards compliant markup
STEP 2: Include the SWFObject JavaScript library in the head of your HTML page
STEP 3: Embed your SWF with JavaScript
STEP 4: Use JavaScript Objects to define your flashvars, params and object’s attributes
TIPS
- Use the SWFObject HTML and JavaScript generator to help you author your code [ http://code.google.com/p/swfobject/wiki/generator ]
- Just repeat steps 1 and 3 to embed multiple SWF files into one HTML page
Why use Dynamic publishing
Description
Create alternative content using standards compliant markup and embed Flash content with unobtrusive JavaScript.
Pros
Avoids ‘click-to-activate’ mechanisms in Internet Explorer 6+ and Opera 9+ and is easy to author (even without using this generator).
Cons
The embedding of Flash content relies on JavaScript, so if you have the Flash plug-in installed, but have JavaScript disabled or use a browser that doesn’t support JavaScript, you will not be able to see your Flash content, however you will see alternative content instead. Flash content will also not be shown on a device like Sony PSP, which has very poor JavaScript support, and automated tools like RSS readers are not able to pick up Flash content.
