Jplayer歌词同步显示插件(在以前别人基础上修改)

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：

         /* 停止执行歌曲 */
         stop: function() {

             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
     });
 });
