public methods

NumberInput re-exposes public method getInputNode(): HTMLInputElement from TextField.

TextField methods: blur, focus, select and getValue are not exposed as they and getInputNode will be removed in material-ui 0.16 and replaced with public member input which is public and now but getInputNode is prefered until 0.16 is released. If you want to use any of those methods call them on input retunrned from getInputNode with the excpetion of getValue instead use value property.

Example

import * as React from 'react';
import NumberInput from 'material-ui-number-input';

class Demo extends React.Component {
  constructor(props) {
  super(props);
  
  this.onKeyDown = (event) => {
    console.log(`onKeyDown ${event.key}`);
  };
  
  this.onChange = (event, value) => {
    const e = event;
    console.log(`onChange ${e.target.value}, ${value}`);
  };
  
  this.onError = (error) => {
    let errorText;
    console.log(error);
    switch (error) {
      case 'required':
        errorText = 'This field is required';
        break;
      case 'invalidSymbol':
        errorText = 'You are tring to enter none number symbol';
        break;
      case 'incompleteNumber':
        errorText = 'Number is incomplete';
        break;
      case 'singleMinus':
        errorText = 'Minus can be use only for negativity';
        break;
      case 'singleFloatingPoint':
        errorText = 'There is already a floating point';
        break;
      case 'singleZero':
        errorText = 'Floating point is expected';
        break;
      case 'min':
        errorText = 'You are tring to enter number less than -10';
        break;
      case 'max':
          errorText = 'You are tring to enter number greater than 12';
          break;
      }
      this.setState({ errorText: errorText });
    };

    this.onValid = (value) => {
      console.debug(`${value} is a valid number`);
    };

    this.onRequestValue = (value) => {
      console.log(`request ${JSON.stringify(value)}`);
      this.setState({ value: value })
    }
  }
    
  render() {
    const { state, onChange, onError, onKeyDown, onValid, onRequestValue } = this; 
    return (
      <NumberInput
        id="num"
        value={state.value}
        required
        defaultValue={9}
        min={-10}
        max={12}
        strategy="warn"
        errorText={state.errorText}
        onValid={onValid}
        onChange={onChange}
        onError={onError}
        onRequestValue={onRequestValue}
        onKeyDown={onKeyDown} />
    );
