经常会在FLASH用到滚轮事件,可是网页中也会响应到, 加下面的代码, 调用就可以了:

package
{
import flash.display.Stage;
import flash.external.ExternalInterface;

/**
  * 滚轮过滤
  * @author cwin5
  */
public class MouseWheelFilter
{
  /**
   * 是否启用
   */
  private static const ENABLE:Boolean = true;

  /**
   * 设置过滤器
   * @param stage
   */
  public static function setFilter():void
  {
   if (!ENABLE)
    return;

   if (ExternalInterface.available)
   {
    ExternalInterface.call("eval", "var _onFlashMousewheel = function(e){"
           + "e = e || event;e.preventDefault && e.preventDefault();"
            + "e.stopPropagation && e.stopPropagation();"
            + "return e.returnValue = false;"
            + "};"
            + "if(window.addEventListener){"
            + "var type = (document.getBoxObjectFor)?'DOMMouseScroll':'mousewheel';"
            + "window.addEventListener(type, _onFlashMousewheel, false);}"
            + "else{document.onmousewheel = _onFlashMousewheel;}");
   }
  }



}

}
