网页FLASH动画禁止右键菜单的方法

在做一个实验时想到要用一个禁止flash的右键功能。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 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 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 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 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 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 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 <stage.stagewidth) {=”” your=”” code=”” here=”” }=”” package=”” import=”” flash.display.*;=”” flash.external.externalinterface;=”” public=”” classclass=”” rightclick=”” extends=”” sprite=”” function=”” rightclick()=”” stage.scalemode=”StageScaleMode.NO_SCALE;” stage.align=”StageAlign.TOP_LEFT;” var=”” methodname:string=”rightClick” ;=”” method:function=”onRightClick;” externalinterface.addcallback(methodname,=”” method);=”” private=”” onrightclick():void=”” mx:int=”stage.mouseX;” my:int=”stage.mouseY;” if(my=””> 0 && my  0 && mx</stage.stagewidth)>
