react-currency-masked-input

Currency Input

<CurrencyInput /> Creates an input that gets masked as currency, in React.

Note: Dollar sign and styling not included

i.e.,

Entering a 1 shows: $0.01.

Entering 11 shows: $0.11.

Entering 110 shows: $1.10.

And so on.

Usage

Install via npm: npm install react-currency-masked-input.

It accepts all properties you'd normally set on an input, so:

// your standard input
 
render() {
  return <input name="myInput" placeholder="0" required />
}

Becomes a matter of simply replacing the tag to CurrencyInput:

// with a currency mask
import CurrencyInput from 'react-currency-masked-input'
 
//...
 
render() {
  return <CurrencyInput name="myInput" required />
}

Props

Prop	Description	Values	Default
separator	The character use as a decimal point	., ,	.

Usage notes:

• renders an input with type="number" and pattern="\d*", but will override those props if you pass them in.
• Will use the defaultValue prop passed in as an initial value, but will take over from there.
• Will become a controlled input if/when props.value is passed to it.
• Calls onChange prop after updating its internal value. First argument is the original event, the second is the masked value.
• Sets the input value on the component instance, so you can reference it on a ref, e.g., myComponent.refs.input.value, as you would with a normal ref.
