播放器插件的封装有点匆忙，尚未细细推敲，也许会有冗余和错误：

(function(mkPlayer) {let defaults = {lrcAr: [ [2.6, "花潮LRC在线", 3] ],lrc_css: 'top: 20px; left: 50%; transform: translateX(-50%);',player_css: 'bottom: 20px; left: calc(50% - var(--ww) / 2);', total: 20,playerCode: `<style>#mplayer {--ww: 200px;--bg: linear-gradient(180deg,gold,lightblue,yellow);--bc: #000;position: absolute;width: var(--ww);height: var(--ww);display: grid;place-items: center;transform: rotateZ(15deg);transform-style: preserve-3d;animation: rot 10s infinite linear;cursor: pointer;}.mline {width: var(--ww);height: var(--ww);border-radius: 50%;border: 1px dotted var(--bc);background: var(--bg);position: absolute;opacity: .75;}#btnMsg { position: absolute; color: snow; background: green; opacity: 0; border: 2px solid snow; border-radius: 8px; padding: 4px; transition: all .75s; cursor: pointer; z-index: 901; }#lrc { --motion: cover2; --tt: 1s; --state: running; --bg: linear-gradient(180deg,hsla(100,10%,50%,.75),hsla(100,100%,20%,.65)); position: absolute; font: bold 2.4em sans-serif; color: hsl(100, 100%, 90%); white-space: pre; -webkit-background-clip: text; filter: drop-shadow(1px 1px 2px hsla(0, 100%, 0%, .85)); z-index: 900; }#lrc::before { position: absolute; content: attr(data-lrc); width: 20%; height: 100%; color: transparent; overflow: hidden; white-space: pre; background: var(--bg); filter: inherit; -webkit-background-clip: text; animation: var(--motion) var(--tt) linear forwards; animation-play-state: var(--state); }@keyframes cover1 { from { width: 0; } to { width: 100%; } }@keyframes cover2 { from { width: 0; } to { width: 100%; } }@keyframes rot { to { transform: rotateZ(15deg) rotateY(1turn); } }</style><div id="lrc" data-lrc="HCPlayer">HCPlayer</div><div id="mplayer"></div><span id="btnMsg">全屏观赏</span>`,};let playCode = (user_config) => {let data = Object.assign({}, defaults, user_config);papa.innerHTML += data.playerCode;mplayer.style.cssText += data.player_css;lrc.style.cssText += data.lrc_css;let mKey = 0, mFlag = true, fs = false, msize = mplayer.offsetWidth, tnow = Date.now(), timerId;;[...Array(data.total).keys()].forEach( (item,key) => {item = document.createElement('span');item.className = 'mline';item.style.transform = `rotateY(${360/data.total*key}deg)`;mplayer.appendChild(item);});mplayer.onclick = () => aud.paused ? aud.play() : aud.pause();btnMsg.onclick = () => fs ? document.exitFullscreen() : papa.requestFullscreen();papa.onmousemove = (e) => {clearTimeout(timerId);btnMsg.style.opacity = '.95';timerId = setTimeout('btnMsg.style.opacity = "0"', 3000);};document.addEventListener("fullscreenchange", () => {if (document.fullscreenElement !== null) {fs = true;mplayer.style.setProperty('--ww', msize*1.5 + 'px');btnMsg.innerText = '退出全屏';} else {fs = false;mplayer.style.setProperty('--ww', msize + 'px');btnMsg.innerText = '全屏观赏';}});aud.addEventListener('pause', () => mState());aud.addEventListener('play', () => mState());aud.addEventListener('seeked', () => calcKey());let mState = () => aud.paused ?

A. 接口参数说明：

一、lrcAr 和以往的插件一样（略）；

二、lrc_css 和以往的插件一样（略）；

三、player_css ：

① CSS变量 --ww 是为播放器尺寸（例如：--ww: 160px; ）；
② CSS变量 --bg 是为播放器的“弧片”颜色，支持纯色（例如：#ffcc00 ）和（例如：--bg: linear-gradient(blue,snow,lightblue); ）；
③ CSS变量 --bc 是为播放器额“弧片”边框颜色，仅支持纯色（例如：--bc: blue; ）；
④ total 变量是为播放器“弧片”总数，数字越大立体球的边框线就越多，建议在 10 ~ 100 之间（例如：total: 20, ）

B. 插件调用举例：

<script >
(function() {
//插件代码放在这里
let lrcAr = [[2,"虹桥",20],[24,"",1]];
HCPlayer({
lrcAr: lrcAr,
lrc_css: '--bg: linear-gradient(blue,lightblue); top: 15px; left: 20px;',
player_css: '--ww: 160px; --bg: linear-gradient(blue,snow,lightblue); --bc: blue; top: 20px;',
total: 20,
});
})();
</script>
