复制代码 代码如下:
var getMonthWeek = function (a, b, c) {
var date = new Date(a, parseInt(b) - 1, c), w = date.getDay(), d = date.getDate();
return Math.ceil(
(d + 6 - w) / 7
);
};
var getYearWeek = function (a, b, c) {
var date1 = new Date(a, parseInt(b) - 1, c), date2 = new Date(a, 0, 1),
d = Math.round((date1.valueOf() - date2.valueOf()) / 86400000);
return Math.ceil(
(d + ((date2.getDay() + 1) - 1)) / 7
);
};
document.write(
"今天是本月的第 ", getMonthWeek(2007, 03, 19), " 周<br \/>"
, "今天是本年的第 ", getYearWeek(2007, 03, 19), " 周"
);
