Question

如果我有X个月，使用Javascript，我该如何将该数字转换为X years and X months？

Answer 1

你可以使用一个函数来强调单数和复数单词。

function getWords(monthCount) {
    function getPlural(number, word) {
        return number === 1 && word.one || word.other;
    }

    var months = { one: 'month', other: 'months' },
        years = { one: 'year', other: 'years' },
        m = monthCount % 12,
        y = Math.floor(monthCount / 12),
        result = [];

    y && result.push(y + ' ' + getPlural(y, years));
    m && result.push(m + ' ' + getPlural(m, months));
    return result.join(' and ');
}

var i;
for (i = 0; i < 30; i++) {
    console.log(getWords(i));
}

Answer 2

对于某个数字x和某个除数y计算除法(div)和余数(rem)为：

var div = Math.floor(x/y);
var rem = x % y;

所以，在你的例子中：

var years = Math.floor(months/12);
var months = months % 12;

Answer 3

试试这个：

months = 14

console.log(
  (months / 12 | 0) + " years and " + months % 12 +" months"
  )

使用此功能

public class MyController : ParentController
{
    public MyController()
        : this(new UserManager<UserModel>(new UserStore(new MyEntities())))
    {
    }

    public UserManager<UserModel> UserManager { get; private set; }

    [HttpPost]
    public async Task<JsonResult> SaveUser(UserModel userModel)
    {
        IdentityResult result = null;
        if (userModel.Id > 0) //want to update user with new encrypted password
            result = await UserManager.UpdateAsync(user);
        else
            result = await UserManager.CreateAsync(userModel.EmailId, userModel.Password);
    }        
}

要获得年份和月份，您只需要使用此功能：-

<script type="text/javascript">
    function years_months(month) 
    {
        if(month==12) {
            var y1 = 1 + " Year";
            return y1;
        } else {
            var y=(month/12);
            var mm=(month%12);
            var ym = y + "Years"+" " + mm + "Months";
            return ym;
        }
    }
</script>

您可以根据需要对此进行改进。这只是一个想法，如何获得解决方案。

使用此功能，已通过Jest（单元测试）进行了测试。

function durationFormatter(monthsCount) {
  const years = Math.floor(monthsCount / 12);
  let yearsDur = years > 0 ? `${years} year` : '';
  yearsDur = years > 1 ? `${yearsDur}s` : yearsDur;

  const restMonths = monthsCount - years * 12;
  let monthsDur = restMonths > 0 ? `${restMonths} month` : '';
  monthsDur = restMonths > 1 ? `${monthsDur}s` : monthsDur;

  const and = years > 0 && restMonths > 0 ? ', and ' : '';

  return `${yearsDur}${and}${monthsDur}`;
}

测试套件

describe('Duration formatter', () => {
  test('formate 12 months duration to 1 year', () => {
    const formatedDuration = durationFormatter(12);
    const expected = '1 year';
    expect(formatedDuration).toBe(expected);
  });

  test('formate 24 months duration to 2 years', () => {
    const formatedDuration = durationFormatter(24);
    const expected = '2 years';
    expect(formatedDuration).toBe(expected);
  });

  test('formate 6 months duration to 6 months', () => {
    const formatedDuration = durationFormatter(6);
    const expected = '6 months';
    expect(formatedDuration).toBe(expected);
  });

  test('formate 1 month duration to 1 month', () => {
    const formatedDuration = durationFormatter(1);
    const expected = '1 month';
    expect(formatedDuration).toBe(expected);
  });

  test('formate 13 months duration to 1 year and 1 month', () => {
    const formatedDuration = durationFormatter(13);
    const expected = '1 year, and 1 month';
    expect(formatedDuration).toBe(expected);
  });

  test('formate 14 months duration to 1 year and 2 months', () => {
    const formatedDuration = durationFormatter(14);
    const expected = '1 year, and 2 months';
    expect(formatedDuration).toBe(expected);
  });

  test('formate 25 months duration to 2 years and 1 month', () => {
    const formatedDuration = durationFormatter(25);
    const expected = '2 years, and 1 month';
    expect(formatedDuration).toBe(expected);
  });

  test('formate 26 months duration to 2 years and 2 months', () => {
    const formatedDuration = durationFormatter(26);
    const expected = '2 years, and 2 months';
    expect(formatedDuration).toBe(expected);
  });
});

var dur1 = Math.floor(months/12);
var dur3 = months - (dur1*12);
