帮帮忙，我怎么在下面这段代码中，让页面也可以用鼠标中轴向下滚动，现在只能拉住侧边才能滚动，
是AS3的代码
stop();
scroll_sb2.scrolling("content_2", "area_2", 0.18); // Range from 0.00 to 1.00
stage.addEventListener(Event.RESIZE, resizeHandler);
function resizeHandler(e:Event):void
{
scroll_sb2.x = stage.stageWidth - scroll_sb2.width - 2;
scroll_sb2.y = 0;
scroll_sb2.height = stage.stageHeight;
area_2.x = stage.stageWidth/2 - area_2.width/2;
area_2.y = stage.stageHeight/2 - area_2.height/2;
area_2.y = 0;
area_2.height = stage.stageHeight;
content_2.x = stage.stageWidth/2 - content_2.width/2;
content_2.y = stage.stageHeight - content_2.height; // comment this line if you whant to remove the carrusel affect on resize browser
}
stage.align = StageAlign.TOP_LEFT;
stage.scaleMode = StageScaleMode.NO_SCALE;
stage.dispatchEvent(new Event(Event.RESIZE));
var mem:String = Number ( System.totalMemory / 2048 / 2048 ).toFixed ( 2 ) + 'Mb';
trace(mem);

看你的代码是使用的组件，看到源文件才能添加这样的操作。
