react-currency-input

An es6 react component for currency. Supports custom decimal and thousand separators as well as precision.

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(newValue){
        this.setState({amount: newValue});
    }
    render() {
        return (
            <div>
                <CurrencyInput value={this.state.amount} onChange={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" />
