想计算每条字幕显示的时间

解决方案

 var t1 = "00:00:13,170";
var t2 = "00:00:16,560";
var间隔毫秒数 = parseInt(t2.split(",")[0].split(",")[0]) * 3600000 +
parseInt(t2.split(",")[0].split(",")[1]) * 60000 +
parseInt(t2.split(",")[0].split(",")[2]) * 1000 +
parseInt(t2.split(",")[1]) -
parseInt(t1.split(",")[0].split(",")[0]) * 3600000 +
parseInt(t1.split(",")[0].split(",")[1]) * 60000 +
parseInt(t1.split(",")[0].split(",")[2]) * 1000 +
parseInt(t1.split(",")[1]);

解决方案二：

转换成秒就除以1000

解决方案三：

转换成时间戳的话更方便处理
