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：
/*****

*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($){

while(item_time = this.regex_time.exec(item[1])) {

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, '']);

$('#'+this.prefixid+'_nofound').hide();
/* 定时调用回调函数，监听歌曲进度 */
//this.handle = setInterval('$.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 */

left = pivot;
}
tmp = left + Math.floor((right - left)/2);
if(tmp == pivot) break;

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
});
});
