react-datetime

A date and time picker in the same React.js component. It can be used as a datepicker, timepicker or both at the same time.

Build Status npm version

It allows to edit even date's milliseconds.

This project started as a fork of https://github.com/quri/react-bootstrap-datetimepicker but the code and the API has changed a lot.

Collaborator needed

I moved to some projects where I don't use this library anymore, and I don't have much time to update it. Since there are a lot of people using it, it would be nice that some dev user could maintain the library. If you think your are good enough to handle this hard task just ping me :)

Usage

Installation :

npm install react-datetime

React.js and Moment.js are peer dependencies for react-datetime. These dependencies are not installed along with react-datetime automatically, but your project needs to have them installed in order to make the datetime picker work.

Then

require('react-datetime');

...

render: function() {
  return <Datetime />;
}

See this example working.

Don't forget to add the CSS stylesheet to make it work out of the box.

API

Name Type Default Description
value Date new Date() Represents the selected date by the component, in order to use it as a controlled component. This prop is parsed by moment.js, so it is possible to use a date string or a moment.js date.
defaultValue Date new Date() Represents the selected date for the component to use it as a uncontrolled component. This prop is parsed by moment.js, so it is possible to use a date string or a moment.js date.
dateFormat bool or string true Defines the format for the date. It accepts any moment.js date format. If true the date will be displayed using the defaults for the current locale. If false the datepicker is disabled and the component can be used as timepicker.
timeFormat bool or string true Defines the format for the time. It accepts any moment.js time format. If true the time will be displayed using the defaults for the current locale. If false the timepicker is disabled and the component can be used as datepicker.
input boolean true Wether to show an input field to edit the date manually.
open boolean null Wether to open or close the picker. If not set react-datetime will open the datepicker on input focus and close it on click outside.
locale string null Manually set the locale for the react-datetime instance. Moment.js locale needs to be loaded to be used, see i18n docs.
onChange function empty function Callback trigger when the date changes. The callback receives the selected moment object as only parameter, if the date in the input is valid. If it isn't, the value of the input (a string) is returned.
onBlur function empty function Callback trigger for when the user clicks outside of the input, simulating a regular onBlur. The callback receives the selected moment object as only parameter, if the date in the input is valid. If it isn't, the value of the input (a string) is returned.
viewMode string or number 'days' The default view to display when the picker is shown. ('years', 'months', 'days', 'time')
className string "" Extra class names for the component markup.
inputProps object undefined Defines additional attributes for the input element of the component.
isValidDate function () => true Define the dates that can be selected. The function receives (currentDate, selectedDate) and should return a true or false whether the currentDate is valid or not. See selectable dates.
renderDay function DOM.td( day ) Customize the way that the days are shown in the day picker. The accepted function has the selectedDate, the current date and the default calculated props for the cell, and must return a React component. See appearance customization
renderMonth function DOM.td( month ) Customize the way that the months are shown in the month picker. The accepted function has the selectedDate, the current date and the default calculated props for the cell, the month and the year to be shown, and must return a React component. See appearance customization
renderYear function DOM.td( year ) Customize the way that the years are shown in the year picker. The accepted function has the selectedDate, the current date and the default calculated props for the cell, the year to be shown, and must return a React component. See appearance customization
strictParsing boolean false Whether to use moment's strict parsing when parsing input.

i18n

Different language and date formats are supported by react-datetime. React uses moment.js to format the dates, and the easiest way of changing the language of the calendar is changing the moment.js locale.

var moment = require('moment');
require('moment/locale/fr');
// Now react-datetime will be in french

If there are multiple locales loaded, you can use the prop locale to define what language should be used by the instance:

<Datetime locale="fr-ca" />
<Datetime locale="de" />

Here you can see the i18n example working.

Appearance customization

It is possible to customize the way that the datetime picker display the days, months and years in the calendar. To adapt the calendar to every need it is possible to use the props renderDay( props, currentDate, selectedDate ), renderMonth( props, month, year, selectedDate ) and renderYear( props, year, selectedDate ) of react-datetime.

var MyDTPicker = React.createClass({
    render: function(){
        return <Datetime
            renderDay={ this.renderDay }
            renderMonth={ this.renderMonth }
            renderYear={ this.renderYear }
        />;
    },
    renderDay: function( props, currentDate, selectedDate ){
        return <td {...props}>{ '0' + currentDate.date() }</td>;
    },
    renderMonth: function( props, month, year, selectedDate){
        return <td {...props}>{ month }</td>;
    },
    renderYear: function( props, year, selectedDate ){
        return <td {...props}>{ year % 100 }</td>;
    }
});

You can see this customized calendar here.

  • props is the object that react-date picker has calculated for this object. It is convenient to use this object as the props for your custom component, since it knows how to handle the click event and its className attribute is used by the default styles.
  • selectedDate and currentDate are Moment.js objects and can be used to change the output depending on the selected date, or the date for the current day.
  • month and year are the numeric representation of the current month and year to be displayed. Notice that the possible month values go from 0 to 11.

Selectable dates

It is possible to disable dates in the calendar if we don't want the user to select them. It is possible thanks to the prop isValidDate, which admits a function in the form function( currentDate, selectedDate ) where both arguments are moment.js objects. The function should return true for selectable dates, and false for disabled ones.

If we want to disable all the dates before today we can do like

// Let's use moment static reference in the Datetime component.
var yesterday = Datetime.moment().subtract(1,'day');
var valid = function( current ){
    return current.isAfter( yesterday );
};
<Datetime isValidDate={ valid } />

See the isValidDate prop working here.

If we want to disable the weekends

var valid = function( current ){
    return current.day() != 0 && current.day() != 6;
};
<Datetime isValidDate={ valid } />

The example working here.
