js计算日期差

var date1 = new Date('2013/04/02 18:00')var date2 = new Date('2013/04/02 19:22:21')var s1 = date1.getTime(),s2 = date2.getTime();var total = (s2 - s1)/1000;var day = parseInt(total / (24*60*60));//计算整数天数var afterDay = tot...

function getTime2Time($time1, $time2) { var time1 = arguments[0], time2 = arguments[1]; time1 = Date.parse(time1)/1000; time2 = Date.parse(time2)/1000; var time_ = time1 - time2; return (time_/(3600*24)); } document.write(getTi...

function getTime2Time($time1, $time2){var time1 = arguments[0], time2 = arguments[1];time1 = Date.parse(time1)/1000;time2 = Date.parse(time2)/1000;var time_ = time1 - time2;return (time_/(3600*24));}document.write(getTime2Time(...

function compare(start,end){ start =start.getTime(); end =end.getTime(); var time =0 if(start>end){ time =start-end; }else{ time =end-start; } return Math.floor(time/86400000) } 参数是时间格式;只取天数,不满一天不算

1.把开始时间和结束时间保存 var dateFrom = new Date(strFrom); var dateTo = new Date(strTo); 2.计算时间差 var diff = dateTo.valueOf() - dateFrom.valueOf(); 3.时间差转换为天数 var diff_day = parseInt(diff/(1000*60*60*24));

//两个日期 var date1 = '2013-03-26'; var date2 = '2011-01-10'; // 拆分年月日 date1 = date1.split('-'); // 得到月数 date1 = parseInt(date1[0]) * 12 + parseInt(date1[1]); // 拆分年月日 date2 = date2.split('-'); // 得到月数 date2 ...

function monthDiff(d1, d2) { var months; months = (d2.getFullYear() - d1.getFullYear()) * 12; months -= d1.getMonth() + 1; months += d2.getMonth(); return months

获取时间差可以通过把2个时间转换为毫秒,然后互减 判断某个时间段是否包含, 如果判断为true,就把时间差再减去这个时间段时间 你最后那个a在12点内13点什么什么的,不懂 规则固定的话大不了写多几个if

var r="2014-01"; var cut=now-r; 你仔细看看,这到底是什么意思??

var time = date2.getTime() - date1.getTime() ; //日期的long型值之差 两个日期相差 Math.floor(time/(24*60*60*1000)) 天
