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 soundAPI,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FlashPlayer插件(当然这不是问题)。这里介绍一下它的用法:
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(){}
});
}
sound.bytesLoaded
sound.bytesTotal
sound.position
sound.duration
sound.id3
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
