我是新手使用extjs。我有月份和年份。我需要根据月份和年份获取当月的第一天和最后一天。
我知道如何获取当前月份的第一天和最后一天。
var date = new Date();
var firstDay = new Date(date.getFullYear(), date.getMonth(), 1);
var lastDay = new Date(date.getFullYear(), date.getMonth() + 1, 0);
例如，在下面的例子中，我有月份和年份，需要获取该月的第一天和最后一天。
var Month = '三月';
var Year = 2023;

function getFirstDayOfMonth(year, month) {
return new Date(year, month, 1);
}
const firstDayJanuary = getFirstDayOfMonth(2023, 0);
console.log('Full Date with First Day : ' + firstDayJanuary);
console.log("First Day of January 2023 is - " + firstDayJanuary.getDay());
function getLastDayOfMonth(year, month) {
return new Date(year, month + 1, 0);
}
const lastDayJan = getLastDayOfMonth(2023, 0);
console.log('Full Date with last Day : ' + lastDayJan);
console.log("Last Day of January 2023 is - " + lastDayJan.getDay());
Output :
Full Date with First Day : Sun Jan 01 2023 00:00:00 GMT+0000 (Coordinated Universal Time)
First Day of January 2023 is - 0 /*0 Indicate Sunday*/
Full Date with last Day : Tue Jan 31 2023 00:00:00 GMT+0000 (Coordinated Universal Time)
Last Day of January 2023 is - 2 /*2 Indicate Tuesday*/
