在AS3中加载外包SWF资料并设定其尺寸

AS3代码：

var paramList:Object = this.root.loaderInfo.parameters;

var bkg = new Loader();var urlReq = new URLRequest(paramList['loadtarget']);

bkg.load(urlReq);var banner = this.addChildAt(bkg, 0);

bkg.contentLoaderInfo.addEventListener(Event.COMPLETE, this.onLoadComplete);

Mouse.cursor = "button";

this.root.addEventListener(MouseEvent.MOUSE_UP, function(event:MouseEvent){

  navigateToURL(newURLRequest(paramList['clickUrl']));																		  });function onLoadComplete(event:Event){	var cWidth = int(paramList['width']);	var cHeight = int(paramList['height']);	var sy = 1000 / cHeight;	var sx = 1000 / cWidth;	var sWith = sx >= sy ? sx : sy;	var ty, tx;		if(cHeight > cWidth){		tx = 0;		ty = ((cHeight - cWidth) / 2) * sWith;	}else if(cWidth > cHeight){		ty = 0;		tx = ((cWidth - cHeight) / 2) * sWith;	}else{		ty = 0;		tx = 0;	} 	with(event.target.loader){		scaleX = sWith; 		scaleY = sWith; 		x  = -tx; 		y  = -ty;	}}
