js计算两个时间之间的天数差
//判断是否为闰年
function isLeapYear(year){
if(year % 4 == 0 && ((year % 100 != 0) || (year % 400 == 0)))
{
return true;
}
return false;
}
//判断前后两个日期
function validatePeriod(fyear,fmonth,fday,byear,bmonth,bday){
if(fyear < byear){
return true;
}else if(fyear == byear){
if(fmonth < bmonth){
return true;
} else if (fmonth == bmonth){
if(fday <= bday){
return true;
}else {
return false;
}
} else {
return false;
}
}else {
return false;
}
}
//计算两个日期的差值
function dateDiff(d1,d2){
var disNum=compareDate(d1,d2);
return disNum;
}
function compareDate(date1,date2)
{
var regexp=/^(\d{1,4})[-|\.]{1}(\d{1,2})[-|\.]{1}(\d{1,2})$/;
var monthDays=[0,3,0,1,0,1,0,0,1,0,0,1];
regexp.test(date1);
var date1Year=RegExp.$1;
var date1Month=RegExp.$2;
var date1Day=RegExp.$3;
regexp.test(date2);
var date2Year=RegExp.$1;
var date2Month=RegExp.$2;
var date2Day=RegExp.$3;
