[Flex] Coding Note

Using Sprite in flex:
class needs to be inherited from "SpriteVisualElement", not "Sprite"

for each and for key:
for each : get value
var obj:Object = {x:10, y:20};
for each (var num in obj)
{
   trace(num); //get 10, 20
}

for (var key:String in obj)
{
     trace(obj[key]);//get 10, 20. but key is x, y
}

[Flex] use SWF in web page

ExternalInterface

The ExternalInterface class is an application programming interface that enables straightforward communication between ActionScript and the SWF container– for example, an HTML page with JavaScript or a desktop application that uses Flash Player to display a SWF file.

Using the ExternalInterface class, you can call an ActionScript function in the Flash runtime, using JavaScript in the HTML page. The ActionScript function can return a value, and JavaScript receives it immediately as the return value of the call.

This functionality replaces the fscommand() method.
