最近專案中需要播放音訊.
視訊之前的已經做了, 要加上播放音訊的功能, 還要相容ie8, 還要禁止下載.

禁止下載這個就不管了, 因為不可能禁止.
要相容ie8, 就不能用<audio>了, ie系列ie9+才支援audio, 具體相容性請看: https://caniuse.com/#search=audio.

找了半天, 發現jPlayer相容ie系列, 就用它了.
其實也看了下, MediaElement.js音訊/視訊都支援, 不過它不支援ie8, 無奈放棄了.
如果不考慮ie8, 可以考慮MediaElement.js, 官網的例子還支援移動端樣式, 感覺不錯.

關於jPlayer

下面是具體程式碼:

<?php
  /*
  需要傳入$_p_audioUrl作為播放地址
  **此外掛需要jquery在其之前載入**
  */
?>

<?php

  // jplayer外掛根目錄
  $_p_jplayerRootPath = 'http://yourdomain/path/to/jplayer';
?>

{if $_p_audioUrl}
<link href="{$_p_jplayerRootPath}/skin/blue.monday/css/jplayer.blue.monday.min.css"
 
 rel="stylesheet" type="text/css" />
<script type="text/javascript" src="{$_p_jplayerRootPath}/jplayer/jquery.jplayer.min.js"></script>
<div id="jquery_jplayer_1" class="jp-jplayer"></div>
<div id="jp_container_1" class="jp-audio" role="application" aria-label="media player">

			<div class="jp-time-holder">

			</div>

    <div class="jp-no-solution">
      <span>提示</span>
      您需要升級瀏覽器或者安裝<a href="http://get.adobe.com/flashplayer/" target="_blank">Flash外掛</a>來播放這段音訊
    </div>

<script type="text/javascript">

$(document).ready(function(){

    mp3: "{$_p_audioUrl}"

實際引用(假定上面的模板叫tpl_audio_player.html):

<?php
$_p_audioUrl = 'http://yourdomain/path/to/xxx.mp3'
include '/path/to/tpl_audio_player.html';
?>

實際效果截圖如下(ui調整過):

歡迎補充指正!
