Installation

To use React-Numpad, install it from NPM and include it in your own React build process (using Webpack, etc).

npm install --save react-numpad

At this point you can import react-numpad in your application

import NumPad from 'react-numpad';

Usage

React-NumPad generates an input field containing the selected value, so you can submit it as part of a standard form. You can also listen for changes with the onChange event property.
When the value is changed, onChange(selectedValue) will fire.

React-NumPad is built based on a "main" component (NumPad.js). Following the higher-order component technique, is possible to create new components by simply overriding few common properties.

NumPad.Number

Input field for numeric value. There are also PositiveNumber, IntegerNumber, PositiveIntegerNumber components with the same properties.

<NumPad.Number
    onChange={(value) => { console.log('value', value)}}
    label={'Total'}
    placeholder={'my placeholder'}
    value={100}
/>

NumPad.Time

Input field with time format.

<NumPad.Time
    onChange={(value) => { console.log('value', value)}}
    label={'Departure time'}
    placeholder={'my placeholder'}
/>

NumPad.Date

Input field with date format.

<NumPad.Date
    onChange={(value) => { console.log('value', value)}}
    label={'Data di nascita di partenza'}
/>

NumPad.DateTime

Input field with date and time format.

<NumPad.DateTime
    onChange={(value) => { console.log('value', value)}}
    dateFormat={'DD.MM.YYYY'}
    label={'Data e ora di partenza'}
    value={'10.02.2018 10:00'}
/>
