用 javascript + actionScript 解决透明的flash在firefox上滚轮失效的有关问题

用 javascript + actionScript 解决透明的flash在firefox下滚轮失效的问题！

1、在flash的宿主文件（HTML）下增加如下代码：

1. <mce:script?language="JavaScript"?type="text/javascript"><!--??????if(!(document.attachEvent))?{??
2. ????????window.addEventListener("DOMMouseScroll",?handleWheel,?false);??????}??
3. ????function?handleWheel(event)?{??????????var?app?=?window.document["${application}"];??
4. ????????if?(app)?{??????????????var?o?=?{x:?event.screenX,?y:?event.screenY,??
5. ????????????????delta:?event.detail,??????????????????ctrlKey:?event.ctrlKey,?altKey:?event.altKey,??
6. ????????????????shiftKey:?event.shiftKey}???????????????
7. ????????????app.handleWheel(o);??????????}??
8. ????}??//?--></mce:script>??

注，${application}为FLEX站点工程下XXX.template的参数，如为其他文件，请改为flash对象的ID值。

2、在flash程序初始化完后，执行此代码：

1. ExternalInterface.addCallback("handleWheel",?handleWheel);??

注：可以把这行代码加入初始化完成的事件回调函数中执行，此函数注册来自javascript函数"handleWheel"的事件，回调函数是handleWheel，此函数代码如下：

?

3、在上面这句代码的函数外，加入此函数：

1. public?function?handleWheel(event:Object):?void?{??????var?obj:InteractiveObject?=?null;??
2. ????var?tmpGlbPoint:Point?=?new?Point(this.mouseX,?this.mouseY);??????var?objects:Array?=?this.getObjectsUnderPoint(tmpGlbPoint);??
3. ????for?(var?i:int?=?objects.length?-?1;?i?>=?0;?i--)?{??????????if?(objects[i]?is?InteractiveObject)?{??
4. ????????????obj?=?objects[i]?as?InteractiveObject;??????????????break;??
5. ????????}?else?{??????????????if?(objects[i]?is?Shape?&&?(objects[i]?as?Shape).parent)?{??
6. ????????????????obj?=?(objects[i]?as?Shape).parent;??????????????????break;??
7. ????????????}??????????}??
8. ????}??????if?(obj)?{??
9. ????????var?tmpP:Point?=?obj.globalToLocal(tmpGlbPoint);??????????var?mEvent:MouseEvent?=?new?MouseEvent(MouseEvent.MOUSE_WHEEL,?true,?false,??
10. ????????????tmpP.x,?tmpP.y,?obj,??????????????event.ctrlKey,?event.altKey,?event.shiftKey,??
11. ????????????false,?-Number(event.delta));??????????obj.dispatchEvent(mEvent);??
12. ????}??}?
