AS3中的一些技巧代码

1、

mc.gotoAndPlay(Math.random()*10>>0);

2、
if(i&1){}

3、
for (var i:int=0; i<10; a.push(i++));

4、
var temp:Number=mouseX;
stage.addEventListener(MouseEvent.MOUSE_MOVE,moveHandler);
function moveHandler(e:MouseEvent):void {
var d:Number=(-temp+(temp=mouseX));
}

5、

function fn1 () {
trace("1");
}
function fn2 () {
trace("2");
}
([fn1,fn2][Math.random()*2>>0])();

6、

var a:int=3;
if (a>0&&(trace("a is positive number"),a1))
trace("a is positive odd  number");

7、
var a:int=13;
var b:int=-12;
if((a^b)>0||(b*=-1,a>10))
trace(b);
//按钮关闭当前网页
import flash.external.ExternalInterface;
a_btn.addEventListener(MouseEvent.CLICK,onHr);
function onHr(e:MouseEvent):void
{
ExternalInterface.call("window.close");
}
