dayOfWeekFormat : int

The format in which the days of the week (in the header) are displayed.

Locale.ShortFormat is the default and recommended format, as Locale.NarrowFormat may not be fully supported by each locale (see 区域设置字符串格式类型 ) 和 Locale.LongFormat may not fit within the header cells.

frameVisible : bool

This property determines the visibility of the frame surrounding the calendar.

默认值为 true .

maximumDate : date

The latest date that this calendar will accept.

By default, this property is set to the latest maximum date (25 October, 275759 AD).

minimumDate : date

The earliest date that this calendar will accept.

By default, this property is set to the earliest minimum date (1 January, 1 AD).

selectedDate : date

The date that has been selected by the user.

This property is subject to the following validation:

• selectedDate will not be changed if undefined or some other invalid value is assigned.
• If there are hours, minutes, seconds or milliseconds set, they will be removed.

The default value is the current date, which is equivalent to:

new Date()
