1、该插件是一个jquery的编写的跟jplayer实现歌词同步的插件,最终效果如图:
2、首先引入jplayer的相关的js库和样式文件。
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <link href="skin/pink.flag/jplayer.pink.flag.css" rel="stylesheet" type="text/css" /> <script type="text/javascript" src="js/jquery-1.8.2.min.js"></script> <script type="text/javascript" src="js/jquery.jplayer.min.js"></script> <script type="text/javascript" src="js/jquery.jplayer.lyric.js"></script>
3、把我修改的jquery的js文件贴出来,以备以后不能下载的朋友参考实现:
/***** *原作mp3player.duapp.com *修改 :王坤 *QQ群:151013733 *修改内容说明:在原有基础上,需要使用start方法才能加载歌词,改进之后,在加载jplayer之前调用,显示歌词 */ (function($){ $.lrc = { handle: null, /* 定时执行句柄 */ list: [], /* lrc歌词及时间轴数组 */ regex: /^[^\[]*((?:\s*\[\d+\:\d+(?:\.\d+)?\])+)([\s\S]*)$/, /* 提取歌词内容行 */ regex_time: /\[(\d+)\:((?:\d+)(?:\.\d+)?)\]/g, /* 提取歌词时间轴 */ regex_trim: /^\s+|\s+$/, /* 过滤两边空格 */ callback: null, /* 定时获取歌曲执行时间回调函数 */ interval: 0.3, /* 定时刷新时间,单位:秒 */ format: '<li>{html}</li>', /* 模板 */ prefixid: 'lrc', /* 容器ID */ hoverClass: 'hover', /* 选中节点的className */ hoverTop: 100, /* 当前歌词距离父节点的高度 */ duration: 0, /* 歌曲回调函数设置的进度时间 */ __duration: -1, /* 当前歌曲进度时间 */ hasLrc:0,/**记录是否有歌词标记**/ //初始化歌词 init: function(txt){ if(typeof(txt) != 'string' || txt.length < 1) return; /* 停止前面执行的歌曲 */ this.stop(); var item = null, item_time = null, html = ''; /* 分析歌词的时间轴和内容 */ //先按行拆分歌词 txt = txt.split("\n"); //对拆分的每行进行提取时间和歌词内容 for(var i = 0; i < txt.length; i++) { //获取一行并去掉两端的空格 [00:11.38]如果你眼神能够为我片刻的降临 item = txt[i].replace(this.regex_trim, ''); //然后取出歌词信息 if(item.length < 1 || !(item = this.regex.exec(item))) continue; while(item_time = this.regex_time.exec(item[1])) { this.list.push([parseFloat(item_time[1])*60+parseFloat(item_time[2]), item[2]]); } this.regex_time.lastIndex = 0; } /* 有效歌词 */ if(this.list.length > 0) { this.hasLrc =1; /* 对时间轴排序 */ this.list.sort(function(a,b){ return a[0]-b[0]; }); if(this.list[0][0] >= 0.1) this.list.unshift([this.list[0][0]-0.1, '']); this.list.push([this.list[this.list.length-1][0]+1, '']); for(var i = 0; i < this.list.length; i++) html += this.format.replace(/\{html\}/gi, this.list[i][1]); /* 赋值到指定容器 */ $('#'+this.prefixid+'_list').html(html).animate({ marginTop: 0 }, 100).show(); /* 隐藏没有歌词的层 */ $('#'+this.prefixid+'_nofound').hide(); /* 定时调用回调函数,监听歌曲进度 */ //this.handle = setInterval('$.lrc.jump($.lrc.callback());', this.interval*1000); }else{ /* 没有歌词 */ this.hasLrc =0; $('#'+this.prefixid+'_list').hide(); $('#'+this.prefixid+'_nofound').show(); } }, /* 歌词开始自动匹配 跟时间轴对应 */ /**callback时间 jplayer的当前播放时间**/ start: function(callback) { this.callback = callback; /* 有歌词则跳转到歌词时间轴 */ if(this.hasLrc == 1) { this.handle = setInterval('$.lrc.jump($.lrc.callback());', this.interval*1000); } }, /* 跳到指定时间的歌词 */ jump: function(duration) { if(typeof(this.handle) != 'number' || typeof(duration) != 'number' || !$.isArray(this.list) || this.list.length < 1) return this.stop(); if(duration < 0) duration = 0; if(this.__duration == duration) return; duration += 0.2; this.__duration = duration; duration += this.interval; var left = 0, right = this.list.length-1, last = right pivot = Math.floor(right/2), tmpobj = null, tmp = 0, thisobj = this; /* 二分查找 */ while(left <= pivot && pivot <= right) { if(this.list[pivot][0] <= duration && (pivot == right || duration < this.list[pivot+1][0])) { //if(pivot == right) this.stop(); break; }else if( this.list[pivot][0] > duration ) { /* left */ right = pivot; }else{ /* right */ left = pivot; } tmp = left + Math.floor((right - left)/2); if(tmp == pivot) break; pivot = tmp; } if(pivot == this.pivot) return; this.pivot = pivot; tmpobj = $('#'+this.prefixid+'_list').children().removeClass(this.hoverClass).eq(pivot).addClass(thisobj.hoverClass); tmp = tmpobj.next().offset().top-tmpobj.parent().offset().top - this.hoverTop; tmp = tmp > 0 ? tmp * -1 : 0; this.animata(tmpobj.parent()[0]).animate({marginTop: tmp + 'px'}, this.interval*1000); }, /* 停止执行歌曲 */ stop: function() { if(typeof(this.handle) == 'number') clearInterval(this.handle); this.handle = this.callback = null; this.__duration = -1; this.regex_time.lastIndex = 0; this.list = []; }, animata: function(elem) { var f = j = 0, callback, _this={}, tween = function(t,b,c,d){ return -c*(t/=d)*(t-2) + b; } _this.execution = function(key, val, t) { var s = (new Date()).getTime(), d = t || 500, b = parseInt(elem.style[key]) || 0, c = val-b; (function(){ var t = (new Date()).getTime() - s; if(t>d){ t=d; elem.style[key] = tween(t,b,c,d) + 'px'; ++f == j && callback && callback.apply(elem); return true; } elem.style[key] = tween(t,b,c,d)+'px'; setTimeout(arguments.callee, 10); })(); } _this.animate = function(sty, t, fn){ callback = fn; for(var i in sty){ j++; _this.execution(i,parseInt(sty[i]),t); } } return _this; } }; })(jQuery);
4、在jplayer初始化中使用如下:
$(document).ready(function(){ $("#jquery_jplayer_1").jPlayer({ ready: function () { //初始化歌词信息(传入歌词文件文本) $.lrc.init($('#lrc_content').val()); $(this).jPlayer("setMedia", { title: "Bubble", mp3: "mp3/林俊杰 - 曹操.mp3" }).jPlayer("play"); }, timeupdate: function(event) { if(event.jPlayer.status.currentTime==0){ time = ""; }else { time = event.jPlayer.status.currentTime; } }, play: function(event) { //点击开始方法调用lrc.start歌词方法 返回时间time if($('#lrc_content').val()!==""){ $.lrc.start(function(){ return time; }); }else{ $(".content").html("没有字幕"); } }, swfPath: "js", supplied: "mp3", wmode: "window", smoothPlayBar: true, keyEnabled: true, remainingDuration: true, toggleDuration: true }); });
5、这一步不是必要的 只是提供一个我的源码给你们参考:
