以下是javascript部分代码：

var RightClick = {
    /**
     * Constructor
     */
    init: function () {
        this.FlashObjectID = "customRightClick";
        this.FlashContainerID = "flashcontent";
        this.Cache = this.FlashObjectID;
        if(window.addEventListener){
             window.addEventListener("mousedown", this.onGeckoMouse(), true);
        } else {
            document.getElementById(this.FlashContainerID).onmouseup = function() { document.getElementById(RightClick.FlashContainerID).releaseCapture(); }
            document.oncontextmenu = function(){ if(window.event.srcElement.id == RightClick.FlashObjectID) { return false; } else { RightClick.Cache = "nan"; }}
            document.getElementById(this.FlashContainerID).onmousedown = RightClick.onIEMouse;
        }
    },
    /**
     * GECKO / WEBKIT event overkill
     * @param {Object} eventObject
     */
    killEvents: function(eventObject) {
        if(eventObject) {
            if (eventObject.stopPropagation) eventObject.stopPropagation();
            if (eventObject.preventDefault) eventObject.preventDefault();
            if (eventObject.preventCapture) eventObject.preventCapture();
         if (eventObject.preventBubble) eventObject.preventBubble();
        }
    },
    /**
     * GECKO / WEBKIT call right click
     * @param {Object} ev
     */
    onGeckoMouse: function(ev) {
        return function(ev) {
        if (ev.button != 0) {
            RightClick.killEvents(ev);
            if(ev.target.id == RightClick.FlashObjectID && RightClick.Cache == RightClick.FlashObjectID) {
                RightClick.call();
            }
            RightClick.Cache = ev.target.id;
        }
      }
    },
    /**
     * IE call right click
     * @param {Object} ev
     */
    onIEMouse: function() {
        if (event.button> 1) {
            if(window.event.srcElement.id == RightClick.FlashObjectID && RightClick.Cache == RightClick.FlashObjectID) {
                RightClick.call();
            }
            document.getElementById(RightClick.FlashContainerID).setCapture();
            if(window.event.srcElement.id)
            RightClick.Cache = window.event.srcElement.id;
        }
    },
    /**
     * Main call to Flash External Interface
     */
    call: function() {
        document.getElementById(this.FlashObjectID).rightClick();
    }
}

以下是as部分代码：

package {

    import flash.display.*;
    import flash.external.ExternalInterface;

    public classclass RightClick extends Sprite
    {

        public function RightClick()
        {
            stage.scaleMode = StageScaleMode.NO_SCALE;
            stage.align = StageAlign.TOP_LEFT;

            var methodName:String = "rightClick";
            var method:Function = onRightClick;
            ExternalInterface.addCallback(methodName, method);
        }

        private function onRightClick():void {

            var mx:int = stage.mouseX;
            var my:int = stage.mouseY;

            if(my> 0 && my 0 && mx                 // YOUR CODE HERE
            }
        }
    }
}
