JS将时间戳转化为时间

//将时间戳转化为时间function timestampToTime(timestamp) { ????var date = new Date(timestamp * 1000);//时间戳为10位需*1000，时间戳为13位的话不需乘1000 ????Y = date.getFullYear() + "-"; ????M = (date.getMonth()+1 < 10 ? ‘0‘+(date.getMonth()+1) : date.getMonth()+1) + ‘-‘; ????D = date.getDate() + " "; ????H = date.getHours() + ":"; ????MIN = date.getMinutes() + ":"; ????S = date.getSeconds(); ????return Y+M+D+H+MIN+S;
