[]scaleMode设为full时怎么pc浏览器跟平板上效果不一样？

public function Main()

{

	Laya.init(Browser.clientWidth, Browser.clientHeight, WebGL);

	

	Laya.stage.bgColor = "#232628";			

	Laya.stage.scaleMode = Stage.SCALE_FULL;

	Laya.stage.screenMode = Stage.SCREEN_NONE;

	Laya.stage.alignH = Stage.ALIGN_CENTER;

	Laya.stage.alignV = Stage.ALIGN_MIDDLE;

	

	Laya.loader.load("assets/bg.jpg", Handler.create(this, loadCompleteHandler));

}

		

private function loadCompleteHandler():void

{

	var bg:Image = new Image("assets/bg.jpg");

	Laya.stage.addChild(bg);

}
