如何在日歷中自動生成年份？

Question

所以，我正在做一個項目，其中包括一個日歷。 所以我下載了一個模板並定制了它。 問題是，日歷只實現了“2017”年。 我的問題是，我可以自動生成接下來的幾年嗎？ 如果我可以，怎么做？

在這里，我向您展示我的代碼（html 和 Js）

索引.html：

<script>
  // fill the month table with column headings
function day_title(day_name) {
    document.write("<div class='c-cal__col'>" + day_name + "</div>");
  }
  // fills the month table with numbers
function fill_table(month, month_length, indexMonth) {
    day = 1;
    // begin the new month table
    document.write("<div class='c-main c-main-" + indexMonth + "'>");
    //document.write("<b>"+month+" "+year+"</b>")

    // column headings
    document.write("<div class='c-cal__row'>");
    day_title("Dom");
    day_title("Seg");
    day_title("Ter");
    day_title("Qua");
    day_title("Qui");
    day_title("Sex");
    day_title("Sab");
    document.write("</div>");

    // pad cells before first day of month
    document.write("<div class='c-cal__row'>");
    for (var i = 1; i < start_day; i++) {
      if (start_day > 7) {
      } else {
        document.write("<div class='c-cal__cel'></div>");
      }
    }

    // fill the first week of days
    for (var i = start_day; i < 8; i++) {
      document.write(
        "<div data-day='2019-" +
          indexMonth +
          "-0" +
          day +
          "'class='c-cal__cel'><p>" +
          day +
          "</p></div>"
      );
      day++;
    }
    document.write("</div>");

    // fill the remaining weeks
    while (day <= month_length) {
      document.write("<div class='c-cal__row'>");
      for (var i = 1; i <= 7 && day <= month_length; i++) {
        if (day >= 1 && day <= 9) {
          document.write(
            "<div data-day='2019-" +
              indexMonth +
              "-0" +
              day +
              "'class='c-cal__cel'><p>" +
              day +
              "</p></div>"
          );
          day++;
        } else {
          document.write(
            "<div data-day='2017-" +
              indexMonth +
              "-" +
              day +
              "' class='c-cal__cel'><p>" +
              day +
              "</p></div>"
          );
          day++;
        }
      }
      document.write("</div>");
      // the first day of the next month
      start_day = i;
    }

    document.write("</div>");
  }

Answer 1

如果您正在尋找不需要自己編寫代碼的快速解決方案，則可以使用類似https://fullcalendar.io/ 的內容。

Answer 2

您可以根據當前年份和模板中所需的年數手動創建年份數組。

以下代碼應涵蓋您需要的基礎知識，根據您的要求更改變量。

let currentYear = new Date().getUTCFullYear();
let startYear = 2016;
let endYearIncrement = 3;
let years = [];

for (let i = 0; i <= currentYear - startYear + endYearIncrement; i++) years.push(startYear + i);

該示例應生成一個具有以下值的數組。

[2016, 2017, 2018, 2019, 2020, 2021, 2022, 2023]

您還可以使用 Javascript 的 Array 內置函數 Array.from() 生成相同的數組。

let years = Array.from( {length: currentYear - startYear + endYearIncrement + 1}, (v, i) => i + startYear )

同樣，您可以更新代碼，以便涵蓋您需要的年份。
