自动播放下一个类实例

我正在使用UbaPlayer,它是一个带有Flash后备的jQuery HTML5音频播放器。 目前,只有在提示的特定歌曲完成后它才会停止播放。

我希望它自动播放按时间顺序排列的下一个“audiobutton”课程。

@Winner_joiner已设法线编辑190移动到下一首歌曲<ul>但的最后一首歌后<ul>结束,它进入的第一个实例<ul class=controls> ,我想为而它继续到下一个<ul>时间顺序实例。

我有一些歌曲之间的内容,所以我必须打破<ul>并开始另一首歌曲。

这是我的HTML:

<head>
<script src="http://code.jquery.com/jquery-1.9.1.min.js"></script>
<script src="src/jquery.ubaplayer.js"></script>
<script>
jQuery(document).ready(function() { 
   jQuery.noConflict();
   jQuery(function(){
            jQuery("#ubaPlayer").ubaPlayer({
            codecs: [{name:"MP3", codec: 'audio/mpeg;'}]
            });

    });
    jQuery('a[rel=vidbox]').click(function () {

        if (jQuery("#ubaPlayer").ubaPlayer("playing") === true) {
            jQuery("#ubaPlayer").ubaPlayer("pause");
            }
        return false;
    });
})
</script>
</head>

<body>
<div id="ubaPlayer"></div>
    <ul class="controls">
        <li><a class="audioButton" href="mp3/dontthinktwice.mp3">
        Don't Think Twice (Bob Dylan)</a></li>
        <li><a class="audioButton" href="mp3/livingforthecity.mp3">
        Living for the City (Stevie Wonder)</a></li>
    </ul>

    <!-- More content and stuff here-->

    <ul class="controls">
        <li><a class="audioButton" href="mp3/anothersong.mp3">
        Another Song</a></li>
        <li><a class="audioButton" href="mp3/anothersong2.mp3">
        Another Song 2</a></li>
    </ul>
</body>

$.fn.ubaPlayer = function(method) {
    if (methods[method]) {
        return methods[method].apply(this, Array.prototype.slice.call(arguments, 1));
    } else if (typeof method === "object" || !method) {
        return _methods.init.apply(this, arguments);
    } else {
        $.error("Method " + method + " does not exist on jQuery.ubaPlayer");
    }
};})(jQuery);

它似乎是lib中的一个错误(或者没有记录的特性)。

它的工作原理只有在audiobuttons是直接的兄弟姐妹(证明在jquery.ubaplayer.js线190)

var $next = $tgt.next().length ? $tgt.next() : $(defaults.audioButtonClass).eq(0);
// a other unrelated bug in the same line is ... $(defaults.audioButtonClass) should be $("." + defaults.audioButtonClass) or so

换句话说,如果你的HTML看起来像这样(with continuous:true):

 <div class="controls"> <!-- THIS IS NOW AN DIV NOT UL-->
     <!-- NO LI'S since the links have to be direkt siblings-->
        <a class="audioButton" href="mp3/dontthinktwice.mp3">
        Don't Think Twice (Bob Dylan)</a>
        <a class="audioButton" href="mp3/livingforthecity.mp3">
        Living for the City (Stevie Wonder)</a>
 </div>

它工作(与铬25 +)

我希望这有帮助。

更新1:

如果您想使用HTML,则必须将文件jquery.ubaplayer.js中的第190行更新为

var $next = $tgt.parent().next().length>0 && $tgt.parent().next().children().length>0?$tgt.parent().next().children().eq(0):$("."+defaults.audioButtonClass).eq(0);
// Code could/should be cleaned up a bit

此代码获取a-Tag = li-Tag的父级,检查它是否具有兄弟,如果是,则获取正确的音频href。

警告我只是检查代码是否运行,对于您的问题,我不知道是否会在其他使用场景中导致问题。 (顺便说一下,我只是改变HTML并离开LIB AS-IS,以便如果更新来临或没有中断更改)

更新2:

通过自动播放功能调用Ubaplayer的代码

 jQuery("#ubaPlayer").ubaPlayer({
        codecs: [{name:"MP3", codec: 'audio/mpeg;'}],
        autoPlay:$(".audioButton").eq(0)
 });
