React numpad


A numpad for number, date and time, built with and for React.
It's written with the extensibility in mind. The idea of this project is to cover the majority of input types in a form.

Demo / Examples

Live demo: gpietro.github.io/docs

Installation

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

``shell
npm install --save react-numpad
`

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

`shell
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.

$3

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

`shell
onChange={(value) => { console.log('value', value)}}
label={'Total'}
placeholder={'my placeholder'}
value={100}
/>
`

Input field with time format.

`shell
onChange={(value) => { console.log('value', value)}}
label={'Departure time'}
placeholder={'my placeholder'}
/>
`

`shell
onChange={(value) => { console.log('value', value)}}

panel: {
backgroundColor: '#CFD8DC'
}
};
