一个禁止flash右键的方法
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();
- }
- }
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
- }
- }
- }
- }
