<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>歌词同步</title> <style> body { background:url("Img/起风了.jpg") center no-repeat ; background-size:60% 100%; } * { margin:0 auto; padding:0; } .play { color: #01e5ff; font-size: 24px; } .overPlay { font-size: inherit; color: #fff; } #p_lrc { position: absolute; padding-top: 0px; left: 28%; top: 300px; width:50%; transition: top .5s; margin: 0 auto; } .p_DisLrc { overflow: hidden; color:#b1abab; width: 70%; height: 600px; position: relative; margin: 0 auto; } #audio { width: 100%; } .p_audio { width: 50%; margin: 0 auto; } .p_but { position: absolute; font-size: 26px; font-weight: 900; top: 40%; right: 0%; } .p_but p { cursor: pointer; } </style> <link href="CSS/iconfont.css" rel="stylesheet" /> </head> <body> <p id="p_1" style="display: none;"> </p> <!-- 歌词显示界面 --> <p class="p_DisLrc"> <p id="p_lrc"> <p id="lrc_row1"></p> </p> <!-- 用于调整歌词位置 --> <p class="p_but"> <p onmousedown="time = setInterval(btn_down,0)" onmouseup="clearInterval (time)"><i class="iconfont icon-top"></i></p> <p onmousedown="time = setInterval(btn_top,0)" onmouseup="clearInterval (time)"><i class="iconfont icon-down"></i></p> </p> </p> <!-- 播放器控件 --> <p class="p_audio"> <audio id="audio" controls="controls" autoplay="autoplay"> <source src="audio/起风了.mp3" type="audio/mpeg"> </audio> </p> <script src="JavaScript/jquery-3.3.1.js"></script> <script> var audio = document.getElementById("audio"); var play = $("#lrc_row1"); //将歌词添加到p中 $(document).ready(function () { //加载歌词 $('#p_1').load("LRC/qifengle.lrc"); //获取所有歌词 setTimeout(function () { var lrcArr = $("#p_1").text().split('\n'); for (var i = 4; i < lrcArr.length; i++) { var p = document.createElement("p"); //空白歌词不进行加载 if (lrcArr[i].substring(10) != "") { p.innerText = lrcArr[i].substring(10); $("#p_lrc").append(p); } } }, 200) }) function lrcDisplay() { //获取播放进度(转换的格式为: 00:00) var minute = parseInt(audio.currentTime / 60);//分钟 minute = minute == 0 ?
