JQuery 获取/设置当前时间“广播电台”答案

【问题标题】：JQuery Get/Set currentTime "Radio Stations"JQuery 获取/设置当前时间“广播电台”
【发布时间】：2018-01-14 01:06:02
【问题描述】：

我想要达到的效果是悬停在某些图标上会播放某些音频文件。当您切换图标时，新音频会从最后一个音频停止的确切时间开始播放 - 这应该就像您正在更改收音机上的频道一样。

下面的代码有效，但仅在两个音频文件之间有效，并且它们绑定到同一个按钮。

我怎样才能复制这种效果，但有 10 个“站”，每个站都有自己的图标？

无需添加多图标。您可以通过创建变量current和next来控制播放哪个

    $(function(){
        var current = -1;
        var next = 0;
        var aAudio = $('audio');
        var audioLen = aAudio.length;
        $(".icon").click(function(){
                if(audioLen <= 0){
                return false;
            }else if(audioLen == 1){
                aAudio.eq(next).trigger('play');

            current = next;

这似乎没有从上次停止的地方获取/设置选定的音频播放？还有多个图标，用户可以选择他们的频道。
