计算两个日期时间差年月日时分秒

function calculateDates (startime,endtime) {
 startime = startime.replace(new RegExp("-","gm"),"/");//转换-变为/
 endtime = endtime.replace(new RegExp("-","gm"),"/");
 var minTime = new Date(startime).getTime()>new Date(endtime).getTime()?endtime:startime
 var maxTime = new Date(startime).getTime()>new Date(endtime).getTime()?startime:endtime
 
 var start       = new Date(minTime);
 var startYear   = start.getFullYear(); //开始年份
 var startMonth  = start.getMonth() + 1;//开始月份
 
 
 var end      = new Date(maxTime);
 var endYear  = end.getFullYear(); //结束年份
 var endMonth = end.getMonth() + 1;//结束月份
 
//  年
 var mideleYear=new Date(minTime)
 mideleYear.setFullYear(endYear)
 var years = Math.abs(mideleYear.getFullYear() - start.getFullYear());
 if(mideleYear.getTime()>end.getTime()){
  years--
 }
