how to disable <ENTER> key for form submit in react-bootstrap

Question

In the following snippet, I have a number of input forms that are type text. If the user hits , it seems I am getting the same synthetic event as if they press the submit button. I want to ignore the as a form submit, and only allow one to press the SUBMIT button. (I deleted some of the Form Groups to cut down on the example).

In all cases (button or ENTER key)

e.key is undefined
e.which is undefined
e.type is submit
e.target is the submit button 

(this is a synthetic event)

const React = require('react')
import { Form, FormControl, FormGroup, ControlLabel, Col, Button, Tooltip, OverlayTrigger } from 'react-bootstrap'

const Configuration = ({ ServerPort, UserID, PortNumber, WWWUrl, SourcePath, FMEPath }) => {
    const buttonAction = (e) => {
        e.preventDefault();
        alert(e.target.innerHTML)
    }
    return (
        <Form horizontal>
            <FormGroup controlId="serverPortBox">
                <Col componentClass={ControlLabel} sm={2}>Watson Port:</Col>
                <Col sm={10}>
                    <OverlayTrigger placement="left" overlay={(<Tooltip id="tt1">TCP port for Watson to use</Tooltip>)}>
                        <FormControl type="number" min="1024" max="65535" placeholder={ServerPort} />
                    </OverlayTrigger>
                </Col>
            </FormGroup>
            <FormGroup controlId="dbPortBox">
                <Col componentClass={ControlLabel} sm={2}>Database Port:</Col>
                <Col sm={10}>
                    <OverlayTrigger placement="left" overlay={(<Tooltip id="tt3">TCP port for PostGreSql DB</Tooltip>)}>
                        <FormControl type="number" min="1024" max="65535" placeholder={PortNumber} />
                    </OverlayTrigger>
                </Col>
            </FormGroup>
            <Button type="submit" bsStyle="primary" block onClick={(e) => buttonAction(e)}>Update Configuration</Button>
        </Form>
    )
}

export default Configuration

Answer 1

Maybe should insert button with type "button" instead "submit"? and then just handle onClick for this button?
