WordPress自定义域与HTML5简洁的音乐播放器

Wordpress自定义域与HTML5简洁的音乐播放器Sixianqiu主题,一个简洁、多形式(标准、图像、相册、音乐、视频、引用与链接),专门为四弦秋发表诗集的Wordpress博客主题。对于音乐和视频本来是打算用网易云音乐和优酷视频,而萨龙龙的所有站点都使用https来访问,网易云音乐与优酷视频并不支持https访问,所以就使用本地HTML5音乐与视频播放器。

本文就来介绍下如何打造一款Wordpress简洁HTML5音乐播放器,并通过自定义域来获取音乐的地址。

HTML5代码

添加到需要显示HTML5音乐播放器的地方

  1. <?php if(get_post_meta($post->ID, "audio", true)) { ?>
  2. <section class="player">
  3. <audio preload="auto" controls>
  4.     <source src="<?php $values = get_post_custom_values("audio"); echo $values[0]; ?>">
  5. </audio>
  6. </section>
  7. <?php } ?>

代码中判断了是否有自定义域audio这个值,如果没有就不输出整段代码。

JS代码

添加到主题的JS文件中

  1. // HTML5播放器
  2. $(function() {
  3.     $('audio').audioPlayer();
  4. });
  5. (function(e, t, n, r) {
  6.     var i = "ontouchstart" in t,
  7.         s = i ? "touchstart" : "mousedown",
