Question

使用此代码我只能启用星期日。但是，如果它是一年中的一周，如何禁用星期日。

function settings(date) {
    if (date.getDay() == 0) {
        return [true, "", "Works"];
    } else {
        return [false, "", ""];
    }
}

$i("#searchsectionbarids").datepicker({
    altField: "#alternate",
    altFormat: "DD",
    dateFormat: 'dd/mm/yy',
    beforeShowDay: settings
});

Answer 1

用它来获取一年中的周数：

Date.prototype.getWeek = function () {
    var firstDay = new Date(this.getFullYear(), 0, 1);
    var today = new Date(this.getFullYear(), this.getMonth(), this.getDate());
    var dayOfYear = ((today - firstDay + 1) / 86400000);
    return Math.ceil(dayOfYear / 7)
};

然后

function settings(date) {
    if (date.getDay() == 0 && date.getWeek() % 2 == 1) {
        return [true, "", "Works"];
    } else {
        return [false, "", ""];
    }
}

首先，你必须检查一周是否均匀你可以参考 Get week of year in JavaScript like in PHP

然后您使用逻辑设置日历
