InputNumber

Enter a number within certain range with the mouse or keyboard.

When To Use#

When a numeric value needs to be provided.

Examples

Numeric-only input box.

import { InputNumber } from 'antd';

function onChange(value) {
  console.log('changed', value);
}

ReactDOM.render(<InputNumber min={1} max={10} defaultValue={3} onChange={onChange} />, mountNode);

Disabled

Click the button to toggle between available and disabled states.

import { InputNumber, Button } from 'antd';

class App extends React.Component {
  state = {
    disabled: true,
  };

  toggle = () => {
    this.setState({
      disabled: !this.state.disabled,
    });
  };

  render() {
    return (
      <div>
        <InputNumber min={1} max={10} disabled={this.state.disabled} defaultValue={3} />
        <div style={{ marginTop: 20 }}>
          <Button onClick={this.toggle} type="primary">
            Toggle disabled
          </Button>
        </div>
      </div>
    );
  }
}

ReactDOM.render(<App />, mountNode);

Formatter

Display value within it's situation with formatter, and we usually use parser at the same time.

import { InputNumber } from 'antd';

function onChange(value) {
  console.log('changed', value);
}

ReactDOM.render(
  <div>
    <InputNumber
      defaultValue={1000}
      formatter={value => `$ ${value}`.replace(/\B(?=(\d{3})+(?!\d))/g, ',')}
      parser={value => value.replace(/\$\s?|(,*)/g, '')}
      onChange={onChange}
    />
    <InputNumber
      defaultValue={100}
      min={0}
      max={100}
      formatter={value => `${value}%`}
      parser={value => value.replace('%', '')}
      onChange={onChange}
    />
  </div>,
  mountNode,
);

Sizes

There are three sizes available to a numeric input box. By default, the size is 32px. The two additional sizes are large and small which means 40px and 24px, respectively.

import { InputNumber } from 'antd';

function onChange(value) {
  console.log('changed', value);
}

ReactDOM.render(
  <div>
    <InputNumber size="large" min={1} max={100000} defaultValue={3} onChange={onChange} />
    <InputNumber min={1} max={100000} defaultValue={3} onChange={onChange} />
    <InputNumber size="small" min={1} max={100000} defaultValue={3} onChange={onChange} />
  </div>,
  mountNode,
);
.ant-input-number {
  margin-right: 10px;
}

Decimals

A numeric-only input box whose values can be increased or decreased using a decimal step. The number of decimals (also known as precision) is determined by the step prop.

import { InputNumber } from 'antd';

function onChange(value) {
  console.log('changed', value);
}

ReactDOM.render(<InputNumber min={0} max={10} step={0.1} onChange={onChange} />, mountNode);
