I am new to Bootstrap and stuck with this problem. I have an input field and as soon as I enter just one digit, the function from onChange is called, but I want

Answer 1

According to React Doc, you could listen to keyboard events, like onKeyPress or onKeyUp, not onChange.

var Input = React.createClass({
  render: function () {
    return ;
  },
  _handleKeyDown: function(e) {
    if (e.key === 'Enter') {
      console.log('do validate');
    }
  }
});

Update: Use React.Component

Here is the code using React.Component which does the same thing

class Input extends React.Component {
  _handleKeyDown = (e) => {
    if (e.key === 'Enter') {
      console.log('do validate');
    }
  }

  render() {
    return 
  }
}

Here is the jsfiddle.

Update 2: Use a functional component

const Input = () => {
  const handleKeyDown = (event) => {
    if (event.key === 'Enter') {
      console.log('do validate')
    }
  }

  return 
}
