js如何获取一个月的天数 function days(year,month){ var dayCount; now = new Date(year,month, 0); dayCount = now.getDate(); return dayCount; } alert(days(2014,7)) javascript获取一个月的天数
发现网上用js获取某月最后一个的方式大多比较复杂,上个简单的: new Date(2013,4).toJSON().substring(0,10) new Date(2013,4,0).toLocaleFormat('%Y-%m-%d') 显示"2013-04-30". year+'-'+month+'-'+new Date(year,month,0).getDate();//获取当月最后一天日期 OK. 另外,前两种方法貌似IE上兼容性有问题,自己看着用吧
1.获取某月第一天和最后一天日期 function getDateByMonth (timeStamp) { let inDate = new Date(timeStamp) let year = inDate.getFullYear() let month = inDate.getMonth() let startTime = new Date(year, month, 1).getTime() let endTime = new Date(year, month + 1, 0).getTim
import java.text.SimpleDateFormat; import java.util.Calendar; public class Test { public static void main(String[] args) { //获取当前时间 Calendar cal = Calendar.getInstance(); //下面可以设置月份,注:月份设置要减1,所以设置1月就是1-1,设置2月就是2-1,如此类推 cal.set(Calendar.MONTH, 1-1); /
