如何从cookie中获取月份的日期？

// 获取cookie的值
function getCookieValue(cookieName) {
  var name = cookieName + "=";
  var decodedCookie = decodeURIComponent(document.cookie);
  var cookieArray = decodedCookie.split(';');
  for (var i = 0; i < cookieArray.length; i++) {
    var cookie = cookieArray[i];
    while (cookie.charAt(0) == ' ') {
      cookie = cookie.substring(1);
    }
    if (cookie.indexOf(name) == 0) {
      return cookie.substring(name.length, cookie.length);
    }
  }
  return "";
}

// 从cookie中获取月份的日期
function getMonthFromCookie() {
  var dateCookie = getCookieValue("date");
  var date = new Date(dateCookie);
  var month = date.getMonth() + 1; // 月份从0开始，需要加1
  return month;
}

// 示例使用
var month = getMonthFromCookie();
console.log("月份：" + month);
