dayjs().set() support Object param?

[sam019]

dayjs().set({
  hour: 12,
  minute: 30,
  second: 30
})

not working...

Update: ObjectSupport plugin https://day.js.org/docs/en/plugin/object-support

---

please use .set(hour).set(minute).set(second) instead

[sam019]

please use .set(hour).set(minute).set(second) instead

thanks.
but it is more convenient if support object param, because momentjs support it, when move from momentjs, it doesn't need to change the code.

[iamkun]

ok we will

plus one on this feature. It's common for Calendar Dates to be represented in Objects via:

{
  year: 2019,
  month: 10, //0-11
  day: 30
}

momentjs accepts this format during initialization. Would be nice if dayjs had similar capabilities

Especially since .toObject() method exist, would be nice to have the way back of it

这么做感觉挺奇怪的。

const toDayjs = (obj: any) => {
  const { years, months, date, hours, minutes, seconds } = obj;
  return dayjs().set('year', years).set('month', months).set('date', date).set('hour', hours).set('minute', minutes).set('second', seconds)
}

toObject 的参数字段和设置的字段也不一样。

moment(moment().toObject())

We just released the ObjectSupport plugin to support this. https://day.js.org/docs/en/plugin/object-support

@iamkun Hello,
Is it correct behaviour that ObjectSupport plugin get month started from 1, but dayjs return month started with 0?

dayjs().get('month') // 8
dayjs({ month: dayjs().get('month') }).get('month') // 7

It's very uncomfortable. I always need to remember that this parts of one lib works in different way.
The expected behaviour something like this:

dayjs().get('month') === dayjs({ month: dayjs().get('month') }).get('month') // true

[iamkun]

@xSorc this is absolutely a bug that I did not review it deeply.

dayjs({month: 1}) 

should return 2020-02-01 instead if 1970-01-01

[iamkun]

@xSorc a fixed pr here #1089

[iamkun]

fix: fix objectSupport plugin to get the correct result (zero-based month) is released in 1.9.1

hi!

i used objectSupport plugin, but for some reason it still doesn'w work :c

dayjs.extend(objectSupport);
dayjs({}); 

it doesn't compile:

TS2769: No overload matches this call.   Overload 1 of 3, '(date?: string | number | Dayjs | Date): Dayjs', gave the following error.     Argument of type '{}' is not assignable to parameter of type 'string | number | Dayjs | Date'.       Type '{}' is missing the following properties from type 'Date': toDateString, toTimeString, toLocaleDateString, toLocaleTimeString, and 37 more.   Overload 2 of 3, '(date?: string | number | Dayjs | Date, format?: OptionType, strict?: boolean): Dayjs', gave the following error.     Argument of type '{}' is not assignable to parameter of type 'string | number | Dayjs | Date'.       Type '{}' is missing the following properties from type 'Date': toDateString, toTimeString, toLocaleDateString, toLocaleTimeString, and 37 more.   Overload 3 of 3, '(date?: string | number | Dayjs | Date, format?: OptionType, locale?: string, strict?: boolean): Dayjs', gave the following error.     Argument of type '{}' is not assignable to parameter of type 'string | number | Dayjs | Date'.       Type '{}' is missing the following properties from type 'Date': toDateString, toTimeString, toLocaleDateString, toLocaleTimeString, and 37 more.

I used other plugins and didn't have any problems with them
what should I do to fix this?

I seem to be getting the same issue as @BigBird15, but when passing the object with year, month, and day.
