使用soundManager soundId从类中获取jQuery

Question

我正在使用音效管理器的bar-ui js。

我有很多球员，所以我需要什么。

我想使用jQuery从html类中选择声音id ..。

我有这个可能?？

就像我在上面的代码中使用内容类一样，所以我可以应用一些自定义更改。

更新

看这里有很多玩家

http://www.schillmania.com/projects/soundmanager2/demo/bar-ui/

下面是soundmanager2代码的示例

var mySoundObject = soundManager.createSound({
    // optional id, for getSoundById() look-ups etc. If omitted, an id will be generated.
    id: 'mySound',
    url: '/audio/mysoundfile.mp3',
    // optional sound parameters here, see Sound Properties for full list
    volume: 50,
    autoPlay: true,
    whileloading: function() {
        console.log(this.id + ' is loading');
    }
});

Answer 1

如果希望通过DOM提供ID，我建议在whileLoading函数中设置一个数据属性，如下所示：

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(_Element_Selector_You_Want_To_Bind_To_).data('sound-id', this.id)
}
});

然后，您可以使用jQuery(_Element_Selector_You_Want_To_Bind_To_).data('sound-id')从元素中检索ID

(由于我通常不使用jQuery，强制香草溶液是document.querySelector(selector).setAttribute('data-sound-id', this.id) document.querySelector(selector).getAttribute('data-sound-id') )

Answer 2

有一个特殊的属性dom存储播放机的所有DOM对象，例如，您可以根据示例中演示的条形ui库的代码通过表达式window.sm2BarPlayers[0].dom (反过来，它利用声音管理器库)。

据我所知，您正在寻找SMSound (通过window.soundManager.getSoundById('sound0')获得)和我提到的player对象之间的连接。这个连接是存在的，它保存在播放器的一个私有变量中(它是一个JS的闭包)：

exports = {
      on: null,
      actions: actions,
      dom: dom,
      playlistController: playlistController
    };
    soundObject = makeSound(playlistController.getURL());

稍后将返回exports变量，这就是指尖上的内容，而soundObject则关闭在内部。不过，正如代码所揭示的那样，似乎有一个技巧可以完成您的任务:您的声音和它的播放器都有相同的url，这就是如何找到连接的方法。换句话说，这是一种方法：

var url = window.soundManager.getSoundById('sound0').url; //get the url of a sound
var player = window.sm2BarPlayers.find(function(p) { return p.playlistController.getURL() == url });
// Here you can use p.dom property where its DOM elements are kept and pass them to jQuery to build other search queries you need

最后，拥有player DOM对象之后，您可以通过标准的JS选择器或jQuery选择器来确定它是在内容区域还是在其他地方。如果您需要详细说明如何处理最后一项任务，请在评论中告诉我。
