如何显示月份和当前工作日的总工作日javascript [英] How to display total workdays in month and current workday javascript

问题描述

正在搜索一种解决方案，以显示当前月的总工作日中的当前工作日.在这种情况下，工作日定义为星期一，星期二，星期三，星期四和星期五.

Was searching for a solution to display the current workday over the total workdays in the current month. Workdays in this case are defined as Mon, Tues, Wed, Thurs, & Fri.

我发现的最接近的解决方案是:

Closest solution I found was this: How to find business days in current month with Javascript?

使用帖子的建议答案并稍加修改，我如何对其进行编辑以显示当月的当前工作日和总工作日?

Using this post's suggested answer with a slight edit, how can I edit this to display the current workday and total workdays in the month?

这是我 CodePen 的尝试.

HTML:

<h3>Get workdays in current month with JavaScript</h3>
<p>Current Day: <span id="currentDay"></span></p>
<p>Total Days: <span id="totalDays"></span></p>

JS:

function isWeekday(year, month, day) {
    var day = new Date(year, month, day).getDay();
    return day !=0 && day !=6;
}
function getWeekdaysInMonth(month, year) {
    var days = daysInMonth(month, year);
    var weekdays = 0;
    for(var i=0; i< days; i++) {
        if (isWeekday(year, month, i+1)) weekdays++;
    }
    $('#totalDays').html(weekdays);
}

推荐答案

这是我的解决方案；应该非常不言自明:

Here's my solution; should be pretty self-explanatory:

const holidays = [
  [7, 4], // 4th of July
  [10, 31] // Halloween
];

var d = new Date();
var currentDay = d.getDate();
var year = d.getYear() + 1900;
var month = d.getMonth();
var total = 0;
var done = 0;
for (var day = 1; day <= 31; day++) {
  var t = new Date(year, month, day);
  if (t.getMonth() > month) break; // month has less than 31 days
  if (t.getDay() == 0 || t.getDay() == 6) continue; // no weekday
  if (holidays.some(h => h[0] - 1 === month && h[1] === day)) continue; // holiday
  total++; // increase total
  if (t.getDate() <= currentDay) done++; // increase past days
}
document.body.innerHTML = `Today is weekday ${done} of ${total}.`

该循环遍历当月的所有天，并计算所有工作日和过去的工作日.

The loop goes through all days of the current month and counts all weekdays and past weekdays.

添加了(不完整的)假日数组并进行检查

added (incomplete) holiday array and check
