## Date-picker(date-picker)
日付の入力にはdate-pickerを使用します。
### 日付の入力
'日'で計測する基本的なdate-picker。
2020-12-08 22:17:20 +08:00
:::demo 測定は `type` 属性で決定されます。You can enable quick options via `shortcuts` property。無効な日付は関数 `disabledDate` で設定する。
2020-11-04 10:30:14 +08:00
```html
< template >

v-model="value1"
type="date"
placeholder="Pick a day">

### その他の測定
標準のdate-pickerコンポーネントを拡張することで、週、月、年、または複数の日付を選択することができます。
:::demo
```html

### デフォルト値
ユーザが日付を指定していない場合は、デフォルトで今日のカレンダーを表示する。別の日付を設定するには `default-value` を用いることができる。その値は `new Date()` で解析可能でなければならない。
型が `daterange` の場合、`default-value` は左側のカレンダーを設定する。
:::demo
```html
< template >
< div class = "block" >
< span class = "demonstration" > date< / span >

:::
### 日付のフォーマット
2021-07-06 15:36:38 +08:00
入力ボックスに表示されるテキストの書式を制御するには `format` を用いる。Use `value-format` to control binding value's format.
2020-11-04 10:30:14 +08:00
2020-11-19 15:58:25 +08:00
デフォルトでは、コンポーネントは `Date` オブジェクトを受け入れて出力します。
Check the list [here ](https://day.js.org/docs/en/display/format#list-of-all-available-formats ) of all available formats of Day.js.
