JavaScript将毫秒转化为年月日时分秒格式

function getSpeTime(timeStr) {// timeStr是毫秒值// 获取年份var year=new Date(timeStr).getFullYear();//获取月份，获取的月份比实际小1，所以需要+1var month=new Date(timeStr).getMonth()+1;//获取日var date=new Date(timeStr).getDate();//获取时var hours=new Date(timeStr).getHours();//获取分var minutes=new Date(timeStr).getMinutes();if (minutes < 10) {minutes = '0' + minutes}//获取秒var seconds=new Date(timdedetail).getSeconds();if (seconds < 10) {seconds = '0' + seconds}//组合格式为年-月-日 时：分：秒（-6-6 12:12:12）return year+"-"+month+"-"+date+" "+hours+":"+minutes+":"+seconds;}
