代碼如下:
var lrc0, lrc1, lrc2;
moveflag = false;
var top, bottom;
var lrcobj;
var lrctop;
predlt = 0;
curdlt = 0;
function lrcClass(tt)
{
this.inr = [];
this.oTime = 0;
this.dts = -1;
this.dte = -1;
this.dlt = -1;
this.ddh;
this.fjh;
if(//[offset/:(/-?/d+)/]/i.test(tt))
this.oTime = RegExp.$1/1000;
tt = tt.replace(//[/:/][^$/n]*(/n|$)/g,"$1");
tt = tt.replace(//[[^/[/]/:]*/]/g,"");
tt = tt.replace(//[[^/[/]]*[^/[/]/d]+[^/[/]]*/:[^/[/]]*/]/g,"");

tt = tt.replace(/<[^<>]*/:[^<>]*[^<>/d/.]+[^<>]*>/g,"");
while(//[[^/[/]]+/:[^/[/]]+/]/.test(tt))
{
tt = tt.replace(/((/[[^/[/]]+/:[^/[/]]+/])+[^/[/r/n]*)[^/[]*/,"/n");
var zzzt = RegExp.$1;
/^(.+/])([^/]]*)$/.exec(zzzt);
var ltxt = RegExp.$2;
var eft = RegExp.$1.slice(1,-1).split("][");
for(var ii=0; ii<eft.length; ii++)
{
var sf = eft[ii].split(":");
var tse = parseInt(sf[0],10) * 60 + parseFloat(sf[1]);
var sso = { t:[] , w:[] , n:ltxt }
sso.t[0] = Math.round((tse-this.oTime)*1000)/1000;
this.inr[this.inr.length] = sso;
}
}
this.inr = this.inr.sort( function(a,b){return a.t[0]-b.t[0];} );
for(var ii=0; ii<this.inr.length; ii++)
{
while(/<[^<>]+/:[^<>]+>/.test(this.inr[ii].n))
{
this.inr[ii].n = this.inr[ii].n.replace(/<(/d+)/:([/d/.]+)>/,"%=%");
