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：

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

            app.handleWheel(o);
        }
    }
// --></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：

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：

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