如何仅显示特定日期的反应日期

Question

I have array of days.

const availableDates = ["2019-02-01", "2019-02-04", "2019-02-05", "2019-02-06", "2019-02-07", "2019-02-11", "2019-02-12", "2019-02-13", "2019-02-14", "2019-02-15", "2019-02-19", "2019-02-20", "2019-02-21", "2019-02-22", "2019-02-23", "2019-02-25", "2019-02-26", "2019-02-27", "2019-02-28", "2019-03-01", "2019-03-04", "2019-03-05", "2019-03-06", "2019-03-07", "2019-03-08", "2019-03-09", "2019-03-11", "2019-03-12"]

I only want to show the above selected days in the airbnb datepicker and disable the other ones.

<SingleDatePicker
    date={moment()}
    onDateChange={date => this.setState({ date })} 
    focused={this.state.focused} 
    onFocusChange={({ focused }) => this.setState({ focused })}
    id="your_unique_id"
    numberOfMonths={1}
    renderCalendarDay={() => availableDates.map(d => moment(d).format(d))}
    className="select-btn selectbtn-picker"
/>

How can I do that? Thank you

You will have to use the isDayBlocked prop of the date picker. The following function will find if a day is contained inside your array, and return true if it does not find any :

isBlocked = day => {
    const availableDates = ["2019-02-01", "2019-02-04", "2019-02-05", "2019-02-06", "2019-02-07", "2019-02-11", "2019-02-12", "2019-02-13", "2019-02-14", "2019-02-15", "2019-02-19", "2019-02-20", "2019-02-21", "2019-02-22", "2019-02-23", "2019-02-25", "2019-02-26", "2019-02-27", "2019-02-28", "2019-03-01", "2019-03-04", "2019-03-05", "2019-03-06", "2019-03-07", "2019-03-08", "2019-03-09", "2019-03-11", "2019-03-12"]
    return !availableDates.some(date => day.isSame(date), 'day')
}

It uses the isSame function of moment.js : https://momentjs.com/docs/#/query/is-same/

Then bind your function :

<SingleDatePicker
    date={moment()}
    onDateChange={date => this.setState({ date })} 
    focused={this.state.focused} 
    onFocusChange={({ focused }) => this.setState({ focused })}
    id="your_unique_id"
    numberOfMonths={1}
    renderCalendarDay={() => availableDates.map(d => moment(d).format(d))}
    className="select-btn selectbtn-picker"
    isDayBlocked={this.isBlocked}
/>

The function mentioned above needs correction, but as the edit is less than 6 chars, the site is not allowing me to. So here is the correct version.

day is supposed to be supplied as the second parameter to moment's isSame function

isBlocked = day => {
    const availableDates = ["2019-02-01", "2019-02-04", "2019-02-05", "2019-02-06", "2019-02-07", "2019-02-11", "2019-02-12", "2019-02-13", "2019-02-14", "2019-02-15", "2019-02-19", "2019-02-20", "2019-02-21", "2019-02-22", "2019-02-23", "2019-02-25", "2019-02-26", "2019-02-27", "2019-02-28", "2019-03-01", "2019-03-04", "2019-03-05", "2019-03-06", "2019-03-07", "2019-03-08", "2019-03-09", "2019-03-11", "2019-03-12"];
    return !availableDates.some(date => day.isSame(date, 'day'));
}
