react-input-range
InputRange
is a React component allowing users to input numeric values within a specific range. It can accept a single value, or a range of values (min/max). By default, basic styles are applied, but can be overridden depending on your design requirements.
Demo
A CodePen demo is available here.
Installation
- Install
react-input-range
using npm (or yarn).npm install react-input-range
- Import
react-input-range
to useInputRange
component. - Optionally, import
react-input-range/lib/css/index.css
if you want to apply the default styling.
Usage
To accept min/max value:
import React from 'react';
import ReactDOM from 'react-dom';
import InputRange from 'react-input-range';
class App extends React.Component {
constructor(props) {
super(props);
this.state = {
value: { min: 2, max: 10 },
};
}
render() {
return (
<InputRange
maxValue={20}
minValue={0}
value={this.state.value}
onChange={value => this.setState({ value })} />
);
}
}
ReactDOM.render(
<App />,
document.getElementById('app')
);
To accept a single value:
class App extends React.Component {
constructor(props) {
super(props);
this.state = { value: 10 };
}
render() {
return (
<InputRange
maxValue={20}
minValue={0}
value={this.state.value}
onChange={value => this.setState({ value })} />
);
}
}
To format labels:
<InputRange
formatLabel={value => `${value}cm`}
value={this.state.value}
onChange={value => this.setState({ value })} />
To specify the amount of increment/decrement
<InputRange
step={2}
value={this.state.value}
onChange={value => this.setState({ value })} />
API
InputRange#props
allowSameValues: boolean
Set to true
to allow minValue
and maxValue
to be the same.
ariaLabelledby: string
Set aria-labelledby
attribute to your component.
ariaControls: string
Set aria-controls
attribute to your component.
classNames: InputRangeClassNames
Override the default CSS classes applied to your component and its sub-components.
disabled: boolean
If this property is set to true, your component is disabled. This means you'll not able to interact with it.
draggableTrack: boolean
If this property is set to true, you can drag the entire track.
formatLabel: (value: number, type: string): string
By default, value labels are displayed as plain numbers. If you want to change the display, you can do so by passing in a function. The function can return something different, i.e.: append a unit, reduce the precision of a number.
maxValue: number
Set a maximum value for your component. You cannot drag your slider beyond this value.
minValue: number
Set a minimum value for your component. You cannot drag your slider under this value.
name: string
Set a name for your form component.
onChange: (value: number | Range): void
Whenever your user interacts with your component (i.e.: dragging a slider), this function gets called. Inside the function, you should assign the new value to your component.
onChangeStart: (value: number | Range): void
Whenever your user starts interacting with your component (i.e.: onMouseDown
, or onTouchStart
), this function gets called.
onChangeComplete: (value: number | Range): void
Every mouse / touch event can trigger multiple updates, therefore causing onChange
callback to fire multiple times. On the other hand, onChangeComplete
callback only gets called when the user stops dragging.
step: number
The default increment/decrement of your component is 1. You can change that by setting a different number to this property.
value: number | Range
Set the current value for your component. If only a single number is provided, only a single slider will get rendered. If a range object (min/max) is provided, two sliders will get rendered
