使用 jquery 和 HTML5 音频标签切换音频源 [英] switch audio source with jquery and HTML5 audio tag

问题描述

我只找到了另一种解决方案，但它不完整，所以我在这里需要帮助.

我设置了音频:

我有一个动态生成的链接表来更改轨道:

<a href="#" class="track" data-location="http://www.newoggtrack.ogg">sample</a>

我有这个 jquery，我不知道如何改变轨道

$('.track').click(function(){load_track = $(this).attr('data-location');//获取新曲目的urlchange_track(load_track);//函数改变加载的音频播放器的轨迹，无需页面刷新首选...});

我找到了这个功能，但我没有正确使用它

 function change_track(sourceUrl) {音频.空()；$("#ogg_src").attr("src", sourceUrl).appendTo(audio);/****************/音频[0].暂停()；audio[0].load();//暂停和恢复所有音频元素/****************/}音频 = $("<audio>").attr("id", "player").attr("预加载", "自动");

解决方案

你的 change 函数应该是这样的:

函数更改(sourceUrl) {var audio = $("#player");$("#ogg_src").attr("src", sourceUrl);/****************/音频[0].暂停()；audio[0].load();//暂停和恢复所有音频元素//音频[0].play();根据以下 Sprachprofi 的评论进行了更改音频[0].oncanplaythrough = 音频[0].play();/****************/}

问题是 audio.empty() 和音频变量.您试图附加一个清空的音频标签，但没有将音频标签写回浏览器.

I have only found one other solution but it was incomplete so I need help here.

i have the audio set up:

<audio id="player" controls="controls">
          <source id="ogg_src" src="lib/audio/barger01.ogg" type="audio/ogg" />
          <source id="mp3_src" src="lib/audio/barger01.mp3" type="audio/mp3" />
          Your browser does not support the audio element.
    </audio>

I have a dynamically generated table of links to change the track:

<div id="audio_list">
   <a href="#" class="track" data-location="http://www.newoggtrack.ogg">sample</a>
</div>

i have this jquery that i have no clue what to do with to change the track

$('.track').click(function(){

    load_track = $(this).attr('data-location');//gets me the url of the new track

    change_track(load_track);// function to change the track of the loaded audio player without page refresh preferred...

});

i found this function but i am not using it the right way

 function change_track(sourceUrl) {

        audio.empty();
        $("#ogg_src").attr("src", sourceUrl).appendTo(audio);
        /****************/
        audio[0].pause();
        audio[0].load();//suspends and restores all audio element
        /****************/
    }

audio = $("<audio>").attr("id", "player")
                        .attr("preload", "auto");

解决方案

Your change function should be like this:

function change(sourceUrl) {
    var audio = $("#player");      
    $("#ogg_src").attr("src", sourceUrl);
    /****************/
    audio[0].pause();
    audio[0].load();//suspends and restores all audio element

    //audio[0].play(); changed based on Sprachprofi's comment below
    audio[0].oncanplaythrough = audio[0].play();
    /****************/
}

The problems were audio.empty() and the audio var. You were attempting to append an emptied audio tag, and didn't write out the audio tag back to the browser.
