SoundManager是 一个JavaScript库,通过它开发者可以控制Web上音频和视频的播放,它包装了Flash sound API,通过JavaScript和ActionScript和通信,来实现了多媒体的互动,所以浏览器需要启用相关版本以上的Flash Player插件(当然这不是问题)。这里介绍一下它的用法:
<script type="text/javascript" src="soundmanager2.js"></script>
soundManager.url='swf'; soundManager.onload=function(){ soundManager.play('sound_id', 'assets/sample.mp3'); }
soundManager.onready(function(status){ if(status.success){ soundManager.play('sound_id', 'assets/sample.mp3'); }else{ alert("soundManager出现异常"); } });
soundManager.onload=function(){ var sound=soundManager.createSound({ id: 'sound_id', url: 'assets/sample.mp3', autoPlay:false //same as default }); sound.play(); }
soundManager.onload=function(){ var sound=soundManager.createSound({ id: 'sound_id', url: 'assets/sample.mp3' }); soundManager.play('sound_id'); }
soundManager.onload=function(){ var sound=soundManager.createSound({ id: 'sound_id', url: 'assets/sample.mp3', autoLoad:true }); sound.play({ duration:1000, volume:80, span:50, onfinish:function(){ this.play(); } }); }
soundManager.onload=function(){ var sound=soundManager.createSound({ id: 'sound_id', url: 'assets/sample.mp3' }); sound.setPosition(1000); sound.setVolume(80); sound.play({pan:-50}); }
sound.play();//播放 sound.pause();//暂停 sound.togglePause();//切换 sound.mute();//静音 sound.unmute();//取消静音 sound.toggleMute();//切换
soundManager.onload=function(){ var sound=soundManager.createSound({ id: 'sound_id', url: 'assets/bad_path.mp3', onload:function(success){ soundManager._writeDebug('sound '+ (success?'loaded':'did not load.'); } }); }
soundManager.onload=function(){ var sound=soundManager.createSound({ id: 'sound_id', url: 'assets/sample.mp3', onfinish:function(){ this.destruct(); } }); }
soundManager.onload=function(){ var sound=soundManager.createSound({ id: 'sound_id', url: 'assets/sample.mp3', onbeforefinishtime:1000, stream:true, whileloading:function(){}, onload:function(){}, onfinish:function(){}, onplay:function(){}, onstop:function(){}, onpause:function(){}, onresume:function(){}, whileplaying:function(){}, onbeforefinish:function(){}, onbeforefinishcomplete:function(){}, onjustbeforefinish:function(){}, onjustbeforefinishcomplete:function(){} }); }

oundManager.allowPolling = true; // 启用状态更新,如果需要监听whileloading/whileplaying则必须启用它 soundManager.consoleOnly = false; // 如果启用了, 则调试到id为soundmanager-debug的DIV soundManager.debugMode = true; //是否启用调试信息, (输出到div#soundmanager-debug,或者console) soundManager.flashLoadTimeout =1000; // 等待影片加载的毫秒数 (0 = infinity) soundManager.flashVersion = 8; // 所需Flash Player的版本 soundManager.nullURL = 'null.mp3'; // (只使用Flash 8): 一个空的辅助MP3文件路径 soundManager.url = '/path/to/swf/'; // 存放SM2 .SWF文件的文件夹路径 soundManager.useConsole = true; // 如果firebug/safari console.log()可用,则使用它 soundManager.useMovieStar = false; // 使用支持 Flash 9.0r115+ MPEG4音频和视频 soundManager.useFastPolling = false; // 默认是200ms跟新一个播放信息,如果启用快速跟新,时间间隔将是1ms soundManager.useHighPerformance = false; // 使用CSS position:fixed来增强JS/AS的调度 soundManager.waitForWindowLoad = false; // window.onload()之后才调用oundManager.onload() soundManager.wmode = 'transparent'; // null, window, transparent, opaque (后两个可以让HTML处于flash上层) soundManager.allowFullScreen = true; // 是否允许全屏
soundManager.canPlayURL(mediaURL:string):Boolean; soundManager.createSound(id:string,url:string):SMSound; soundManager.createSound(options:object):SMSound; soundManager.createVideo(options:object):SMSound; soundManager.destroySound(id:string); soundManager.destroyVideo(id:string); soundManager.onready(callback:function(status),[scope]); soundManager.loadFromXML(xmlURL:string); soundManager.supported():Boolean;
这些方法简单明了,通过方法名称都应该可以猜的到作用是什么了。其中,loadFromXML(xmlURL:string)用来播放一个XML文件定义的媒体列表;supported()用来判断soundManager初始化完成。
