react-currency-input

An ES2015 react component for currency. Supports custom decimal and thousand separators as well as precision.

Changes

v1.3.0:

Deprecated "onChange" option in favor of "onChangeEvent". This fixes the argument order to better match React's default input handling
Updated dependencies to React 15
Added parseFloat polyfill
Persist events to deal with an issue of event pooling
Other bug fixes.

Installation

npm install react-currency-input --save

Integration

You can store the value passed in to the change handler in your state.

import React from 'react'
import CurrencyInput from 'react-currency-input';

const MyApp = React.createClass({
    getInitialState(){
        return ({amount: "0.00"});
    },

    handleChange(event, maskedvalue, floatvalue){
        this.setState({amount: maskedvalue});
    },
    render() {
        return (
            <div>
                <CurrencyInput value={this.state.amount} onChangeEvent={this.handleChange}/>
            </div>
        );
    }
});
export default MyApp

You can also assign a reference then access the value using a call to getMaskedValue().

import React from 'react'
import CurrencyInput from 'react-currency-input';

const MyApp = React.createClass({
    handleSubmit(event){
        event.preventDefault();
        console.log(this.refs.myinput.getMaskedValue())
    },
    render() {
        return (
            <form onSubmit={this.handleSubmit}>
                <CurrencyInput ref="myinput" />
            </form>
        );
    }
});
export default MyApp

Separators and Precision

Specify custom decimal and thousand separators:

    // 1.234.567,89
    <CurrencyInput decimalSeparator="," thousandSeparator="." />

Specify a specific precision:

    // 123,456.789
    <CurrencyInput precision="3" />

    // 123,456,789
    <CurrencyInput precision="0" />

Currency

Optionally set a currency symbol as a prefix or suffix

    // $1,234,567.89
    <CurrencyInput prefix="$" />

    // 1,234,567.89 kr
    <CurrencyInput suffix=" kr" />

Negative signs come before the prefix

    // -$20.00
    <CurrencyInput prefix="$" value="-20.00" />

All other attributes are applied to the input element. For example, you can integrate bootstrap styling:

    <CurrencyInput className="form-control" />

Options

Option	Default Value	Description
value	0	The initial currency value
onChange	n/a	Callback function to handle value changes. Deprecated, use onChangeEvent.
onChangeEvent	n/a	Callback function to handle value changes
precision	2	Number of digits after the decimal separator
decimalSeparator	'.'	The decimal separator
thousandSeparator	','	The thousand separator
inputType	"text"	Input field tag type. You may want to use `number` or `tel`*
allowNegative	false	Allows negative numbers in the input
allowEmpty	false	If no `value` is given, defines if it starts as null (`true`) or '' (`false`)
selectAllOnFocus	false	Selects all text on focus or does not
prefix	''	Currency prefix
suffix	''	Currency suffix
autoFocus	false	Autofocus

*Note: Enabling any mask-related features such as prefix, suffix or separators with an inputType="number" or "tel" could trigger errors. Most of those characters would be invalid in such input types.
