已实现周末排除天数统计，如何用jQuery获取对应所有日期？

Got it, so you already have a function that counts business days, but you need to pull the actual list of those dates instead of just the count. Let's build a straightforward, easy-to-maintain solution using JavaScript (works seamlessly in jQuery environments):

Implementation Code #

function getBusinessDates(startDate, endDate) {
  const businessDates = [];
  // Create a copy of the start date to avoid modifying the original input
  const currentDate = new Date(startDate);

  // Loop through each day from start to end date
  while (currentDate <= endDate) {
    const dayOfWeek = currentDate.getDay();
    // Exclude Sunday (0) and Saturday (6)
    if (dayOfWeek !== 0 && dayOfWeek !== 6) {
      // Push a copy of the current date to prevent reference issues
      businessDates.push(new Date(currentDate));
    }
    // Move to the next day
    currentDate.setDate(currentDate.getDate() + 1);
  }

  return businessDates;
}

Key Details to Note #

• Date Object Copies: Since Date is a reference type, we create fresh copies when adding to the array. This prevents later modifications to currentDate from altering dates already stored in the list.
• Weekday Check: getDay() returns 0 for Sunday and 6 for Saturday—we skip these and keep days 1-5 (Monday to Friday).
• Inclusive Range: The loop runs as long as currentDate is less than or equal to endDate, so the end date is included if it's a weekday.

Example Usage #

Let's test your sample scenario: Friday to Monday

// Define start (Fri, May 17 2024) and end (Mon, May 20 2024) dates
// Note: Months are 0-indexed in JavaScript Date
const start = new Date(2024, 4, 17);
const end = new Date(2024, 4, 20);

// Get the list of business dates
const dates = getBusinessDates(start, end);

// Print formatted dates (e.g., YYYY-MM-DD)
function formatDate(date) {
  const year = date.getFullYear();
  const month = String(date.getMonth() + 1).padStart(2, '0');
  const day = String(date.getDate()).padStart(2, '0');
  return `${year}-${month}-${day}`;
}

dates.forEach(date => console.log(formatDate(date)));
// Output:
// 2024-05-17
// 2024-05-20

This approach is more intuitive than reverse-engineering dates from a count, and it's easy to extend later—for example, if you need to exclude holidays, you can just add an extra check in the loop.
