我有一些朋友的生日,想按如下方式把它们分开:如何检查日期是在本周内或本月内或下个月在JavaScript?
- 生日落于本周内(在本周剩余天从当天开始)。
- 本月内的生日(从本日起的本月的剩余日期内)。
- 下个月内的生日。
所以我想知道如何在javascript中测试每个日期以查看它是否在本周/当前月份/下个月的剩余日期内。
N.B:说我有m/d/Y(06/29/1990)格式的日期。
感谢

将您的日期和当前时间Date
对象,并用它进行比较。一些干编码:
var now = new Date()
if (
(check.getFullYear() == now.getFullYear()) &&
(check.getMonth() == now.getMonth()) &&
(check.getDate() >= now.getDate())
) {
// remanining days in current month and today. Use > if you don't need today.
}
var nextMonth = now.getMonth() + 1
var nextYear = now.getFullYear()
if (nextMonth == 12) {
nextMonth = 0
nextYear++
}
if (
(check.getFullYear() == nextYear) &&
(check.getMonth() == nextMonth)
) {
// any day in next month. Doesn't include current month remaining days.
}
var now = new Date()
now.setHours(12)
now.setMinutes(0)
now.setSeconds(0)
now.setMilliseconds(0)
var end_of_week = new Date(now.getTime() + (6 - now.getDay()) * 24*60*60*1000)
end_of_week.setHours(23)
end_of_week.setMinutes(59)
end_of_week.setSeconds(59) // gee, bye-bye leap second
if (check >=now && check <= end_of_week) {
// between now and end of week
}
代码使用解析日期是
var selecteddate = '07/29/1990';
var datestr = selecteddate.split('/');
var month = datestr[0];
var day = datestr[1];
var year = datestr[2];
var currentdate = new Date();
var cur_month = currentdate.getMonth() + 1;
var cur_day =currentdate.getDate();
var cur_year =currentdate.getFullYear();
if(cur_month==month && day >= cur_day)
{
alert("in this month");
}
else
{
alert("not in this month");
}
任何方式来获得本周? – flyleaf 2012-07-09 10:04:12
