如何获取下周的月、周、日格式列表？

Question

i want to get the list of next week days in given format "March 12 Sunday" and then convert that is final list of week days as given below. Here is a my current code with which i am trying to get desire output but that returns "06/12/22" format..

Current code:

const nextWeek = [...Array(7).keys()].map(days => new Date(Date.now() + 86400000 * days).toLocaleDateString('en-us', { weekday:"long", month:"short", day:"numeric"}))
        console.log("== > ",nextWeek)

current output:

["09/17/22", "09/18/22", "09/19/22", "09/20/22", "09/21/22", "09/22/22", "09/23/22"]

first i want this output

 ["Sunday, March 4", "Monday, March 4", "Tuesday, March 4", "Wednesday, March 4", "Thursday, March 4", "Friday, March 4", "Saturday, March 4"]

and then final desire output is:

const nextWeekdata = [

            { id: 1, name: "Sunday" ,date:21,Month:"March" },
            { id: 2, name: "Monday" ,date:22,Month:"March" },
            { id: 3, name: "Tuesday" ,date:23,Month:"March" },
            { id: 4, name: "Wednesday" ,date:24,Month:"March" },
            { id: 5, name: "Thursday" ,date:25,Month:"March" },
            { id: 6, name: "Friday" ,date:26,Month:"March" },
            { id: 7, name: "Saturday" ,date:27,Month:"March" },
          ];

Answer 1

    const nextWeek = [...Array(7).keys()].map((days) =>
  new Date(Date.now() + 86400000 * days).toLocaleDateString("en-us", {
    weekday: "long",
    month: "short",
    day: "numeric",
  })
);
let newArray = [];
nextWeek.forEach((item, index) => {
  let data = item.split(",");
  let secondLength = data[1].length;
  newArray.push({
    id: index + 1,
    name: data[0],
    date: data[1].substring(secondLength - 2),
    month: data[1].substring(1, secondLength - 3),
  });
});
console.log("days", newArray);

does this work? yes

is this the right way to do it? nope

is this the easy way? for me, it is.

If you want to calculate the range of dates for next week, break your logic into smaller chunks.

You should have three functions:

• Function that gets the date for a given day of the week; next week
• Function that gets the range of all the dates next week
• Function to map the dates to object data

 const getNextDay = (dayIndex) => { const today = new Date(); today.setDate(today.getDate() + (dayIndex - 1 - today.getDay() + 7) % 7 + 1); return today; }; const getNextWeek = () => [...Array(7).keys()].map(getNextDay); const nextWeek = getNextWeek().map((date, index) => ({ id: index + 1, name: date.toLocaleDateString('en-us', { weekday: 'long' }), date: date.getDate(), month: date.toLocaleDateString('en-us', { month: 'long' }), year: date.getFullYear() })); console.log(nextWeek);

 .as-console-wrapper { top: 0; max-height: 100%;important; }

Answer 3

Actually, when I use your current code I get this as a result:

(7) ['Saturday, Sep 17', 'Sunday, Sep 18', 'Monday, Sep 19', 'Tuesday, Sep 20', 'Wednesday, Sep 21', 'Thursday, Sep 22', 'Friday, Sep 23']

Which means it works as you wish; what browser are you using?

Regarding the Second Question of yours, I'd have used something such as this:

class weekDay {
   constructer(id, x) {
      let name = x.split(", ")[0];
      let day = x.split(", ")[1].split(" ")[1];
      let month = x.split(", ")[1].split(" ")[0];
      this.id = id;
      this.name = name;
      this.day = day;
      this.month = month;
   }
}
const nextWeek = [...Array(7).keys()].map(days => new Date(Date.now() + 86400000 * days).toLocaleDateString('en-us', { weekday:"long", month:"long", day:"numeric"}))
var arr = [];
for (let i=0; i<=6; i++) {
   arr.push(new weekDay(i+1, nextWeek[i]));
}

This is my way of doing it, but take heed that I haven't tested it so it might have some syntax errors, if there was any, please notify me.
