Webjx核心提示：网页FLASH动画禁止右键菜单的方法.

在做一个实验时遇到一个禁止flash的右键功能的问题。在网上找了很多方法，要不就完全不行，要不就浏览器不兼容。Google了一下国外的情况，终于找到了一个不错的方法。该方法用了javascript和as的结合，完美解决了问题。

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();
}
}

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 <stage.stageHeight && mx> 0 && mx <stage.stageWidth) {
// YOUR CODE HERE
}
}
}

1. }

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
