我正在使用soundmanager的bar-ui js。
http://www.schillmania.com/projects/soundmanager2/demo/bar-ui/
我有很多玩家,因此当页面加载播放器加载时,我不知道我想要什么。
http://support.simplepodcaster.com/auto-timestamps/
看到我想在我的页面上有三个玩家....
我试过了
var mySoundObject = soundManager.createSound({
id: 'mySound',
url: '/audio/mysoundfile.mp3',
// optional sound parameters here, see Sound Properties for full list
volume: 50,
autoPlay: true,
whileloading: function() {
jQuery(".playercontent").data('sound-id', this.id);
}
});
但问题是我可以获得声音,直到我玩,否则我无法获得身份。
页面加载时有没有办法获取id?
答案 0 :(得分:3)
当您使用createSound()
时,它可以生成ID,或者分配一个(就像您现在一样)。
在您粘贴的示例中,您提供了一个id,因此您将从soundmanager覆盖它的创建。那就是你的声音会有id='mySound'
。在docs之后,您可以看到我在这里写的内容。
相反,如果您创建声音(或您的情况下的播放器),您可以为每个声音设置一个id,例如,通过创建一个带有该播放器的mp3轨道的名称或url的哈希值(所以,您可以稍后通过您可以生成的ID找到您的声音)
这样的事情:
var url='/audio/mysoundfile.mp3';
var id=md5(url); // hash it here
var mySoundObject = soundManager.createSound({
id: id,
url: url,
// optional sound parameters here, see Sound Properties for full list
volume: 50,
autoPlay: true
//whileloading: function() {
//jQuery(".playercontent").data('sound-id', this.id);
//}
});
jQuery(".playercontent").data('sound-id', id);
或者只是获得如下ID:
var mySoundObject = soundManager.createSound({
url: '/audio/mysoundfile.mp3',
// optional sound parameters here, see Sound Properties for full list
volume: 50,
autoPlay: true,
// whileloading: function() {
// jQuery(".playercontent").data('sound-id', this.id);
// }
});
console.log(mySoundObject.id);
jQuery(".playercontent").data('sound-id', mySoundObject.id);
对于这两种情况,您都可以使用以下方法来抓取您在网站directly中创建的任何声音/播放器:
var track='/audio/mysoundfile.mp3';
var id= md5(track);
var mySoundObject = soundManager.getSoundById(id);
另一方面,您可以使用setVolume()
之类的回调或强制加载mp3文件( SMSound对象中的任何方法都有 this.id
上下文中可用的字段)。
但是,使用这样的东西并不是真的有必要才能获得声音/播放器的ID。
也许有了这些信息,您可以更好地组织您网站上的玩家。

好吧,在Evhz帮助我之后我得到了它。
但他没有发布md5() function
那我在bar-ui.js
第168行
function makeSound(url) {
var sound = soundManager.createSound({
url: url,
使用此代码更改
function makeSound(url) {
var soundid = md5(url);
var getsound = window.soundManager.getSoundById(soundid);
if (typeof getsound == 'undefined') {
soundid = md5(url);
}else{
soundid = soundid + 'n';
}
var sound = soundManager.createSound({
url: url,
id: soundid,
这里是md5函数

return (lValue<<iShiftBits) | (lValue>>>(32-iShiftBits));

现在我可以使用此代码从播放器html中获取声音
var soundurl = jQuery( ".playercontent").find('.sm2-playlist-wrapper ul li a').attr('href');
var Soundid= md5(soundurl);
