ActionScript 中的 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
