Javascript数组排序并制定与天数范围相同的时间表

Question

我收到了 CSV 格式的办公日程表，其中包含具有相同日程安排的日期的破折号范围。

例如，今天是星期四:

Mon 3:00am - 9:00pm, Tue - Thu 5:30am - 9:30pm, Fri 7:15am - 10:00pm, Sat 8:00am - 3:00pm, Sun Closed

我需要删除周日关闭时间表并首先显示周四，例如，如果今天是周四

我的预期输出是这样的:

Tue - Thu 5:30am - 9:30pm, Fri 7:15am - 10:00pm, Sat 8:00am - 3:00pm, Mon 3:00am - 9:00pm

如果今天是星期四(当天)，一些示例和预期结果:

“周一 4:00am - 9:00pm，周二 6:00am - 9:30pm，周三 - 周五 5:30am - 9:30pm，周六 8:00am - 3:00pm，周日休息” 预期结果:“周二 6:00am - 9:30pm，周三 - 周五 5:30am - 9:30pm，周六 8:00am - 3:00pm，周一 4:00am - 9:00pm”

“周三 5:30am - 9:30pm，周四 6:30am - 4:00pm，周五至周二 8:00am - 3:00pm，周日休息” 预期结果:'周四上午 6:30 - 下午 4:00，周五至周二上午 8:00 - 下午 3:00，“周三上午 5:30 - 下午 9:30”

“周一至周二上午 5:30 - 下午 9:30，周三上午 6:30 - 下午 4:00，周四至周六上午 8:00 - 下午 3:00，周日休息” 预期结果:“周四至周六上午 8:00 - 下午 3:00，周一至周二上午 5:30 - 晚上 9:30，周三上午 6:30 - 下午 4:00”

我当前的代码部分工作:

function sortDays(days) {
    var dayOfWeek = new Date().getDay();
    var list = ['Sun', 'Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat'];
    var sortedList = list.slice(dayOfWeek).concat(list.slice(0, dayOfWeek));
    return days.sort(function(a,b) { return sortedList.indexOf(a) > sortedList.indexOf(b); });
}

function removeA(arr) {
    var what, a = arguments, L = a.length, ax;
    while (L > 1 && arr.length) {
        what = a[--L];
        while ((ax= arr.indexOf(what)) !== -1) {
            arr.splice(ax, 1);
        }
    }
    return arr;
}

function getDaysRange(first, last) {
    // var week = new Array('Sunday', 'Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday');
    var week = ['Sun', 'Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat'];

    // Find first day
    var firstIndex = week.indexOf(first);
    // Shift array so that first day is index 0
    week = week.concat(week.splice(0, firstIndex));
    // Find last day
    var lastIndex = week.indexOf(last);

    // Cut from first day to last day and convert to CSV string
    // return week.slice(0, lastIndex + 1).toString();
    return week.slice(0, lastIndex + 1);
}

以下内容可能会起作用，它不会删除“Sun”，不确定您是否只是想删除那一天还是因为它恰好关闭。

const week = [
  'Sun',
  'Mon',
  'Tue',
  'Wed',
  'Thu',
  'Fri',
  'Sat',
];
const withDayPair = (item) => {
  //add [dayOneIndex, dayTwoIndex] to value
  const parts = item
    .split('-')
    .map((s) => s.trim())
    .map((s) => s.substr(0, 3));
  if (parts.length > 2) {
    //this value has day range (for example Mon - Wed)
    return [
      parts.slice(0, 2).map((p) => week.indexOf(p)),
      item,
    ];
  }
  return [[week.indexOf(parts[0]), -1], item]; //only one day, set second day to -1
};
const assignValue = (current) => ([[a, b], item]) => {
  //assign a value for sorting. If both values are smaller than current (earlier in the week)
  //  then add 10 to the index of the value in the array
  const val = a < current && b < current ? a + 10 : a;
  return [val, item];
};
const sortWith = (str, day) =>
  str
    .split(',')
    .map((s) => s.trim())
    .filter((s) => !s.startsWith('Sun'))//remove sunday
    //having a string representing days of week is not the best way to represent
    //  the data types used in your application
    .map(withDayPair)
    //now the values will be [[1,3],'Mon - Wed ....']
    .map(assignValue(week.indexOf(day))) //the [1,3] part is replaced with one number
    .sort(([a], [b]) => a - b) //sorting on that number
    .map(([_, item]) => item); //remove the number
const testVal =
  'Mon - Tue 5:30am - 9:30pm, Wed 6:30am - 4:00pm, Thu - Sat 8:00am - 3:00pm, Sun Closed';
console.log(
  //test for every day in the week
  ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat']
    .map(
      (day) =>
        `Day:${day} == ${sortWith(testVal, day).join(',')}`,
    )
    .join('\n'),
);
