jquery音乐播放器（歌词滚动版）

好久没出来水了！！！忙忙碌碌的找工作~然后中秋节也算过了，祝各位coding们，直接觉醒第七感小宇宙，直接用心就能找到bug-_-//

最后如题这是一篇很正规的coding的文章

大概么比以前的加了个歌词，之前的炸了，然后最近又修好了，一直东西在搬家，这次估计不搬家了，大不了美橙在买几个空间hoho

 

效果么大概一下，花了1个钟头快速写出来的~都说每个程序猿都有一颗设计狮的心，但是我记得我以前开始码代码之前做设计的时候，有一句话你设计不出来不会抄啊，然后我就无耻的盗图了。23333

 

头部很多人说丑，火车和天空，然后么还是有点含义的吧！可以听下《爱情转移》有一句歌词

 

$.ajax({
    url: "/music/music.txt",
    type: "get",
    success: function(data) {
        data = jQuery.parseJSON(data);
        var length = data.length;
        var now=0;
        for (i = 0; i < length; i++) {
            $("#musicText li").eq(i).after("<li>" + data[i].text + "</li>")

            }
        }
 }
})

 

然后这里的代码是alpha0.0.1版的，一直在升级ing

 

继续改bug了，直接网站源代码就可以查看~

 

最后大神看到别打脸，别攻击我T_T，别留hacker~email了。。这个月我还原了N次了...实在不高兴这么个玩意还装安全狗之类的
