¿Cómo enviar un formulario usando la tecla Intro en react.js?

Question

Aquí está mi formulario y el método onClick. Me gustaría ejecutar este método cuando se presiona el botón Enter del teclado. Cómo ?

NB: No se aprecia jquery.

 comment: function (e) {
e.preventDefault();
this.props.comment({comment: this.refs.text.getDOMNode().value, userPostId:this.refs.userPostId.getDOMNode().value})
},
<form className="commentForm">
<textarea rows="2" cols="110" placeholder="****Comment Here****" ref="text" /><br />
<input type="text" placeholder="userPostId" ref="userPostId" /> <br />
<button type="button" className="btn btn-success" onClick={this.comment}>Comment</button>
</form>

Answer 1

Cambie <button type="button" a <button type="submit" . Elimina el onClick . En su lugar, haga <form className="commentForm" onSubmit={this.onCommentSubmit}> . Esto debería coger haciendo clic en el botón y presionando la tecla de retorno.

onFormSubmit = e => {
e.preventDefault();
const { name, email } = this.state;
// send to server with e.g. `window.fetch`
}
...
<form onSubmit={this.onFormSubmit}>
...
<button type="submit">Submit</button>
</form>

Answer 2

Use el evento keydown para hacerlo:

 input: HTMLDivElement | null = null;
onKeyDown = (event: React.KeyboardEvent<HTMLDivElement>): void => {
// ''keypress'' event misbehaves on mobile so we track ''Enter'' key via ''keydown'' event
if (event.key === ''Enter'') {
event.preventDefault();
event.stopPropagation();
this.onSubmit();
}
}
onSubmit = (): void => {
if (input.textContent) {
this.props.onSubmit(input.textContent);
input.focus();
input.textContent = '''';
}
}
render() {
return (
<form className="commentForm">
<input
className="comment-input"
aria-multiline="true"
role="textbox"
contentEditable={true}
onKeyDown={this.onKeyDown}
ref={node => this.input = node}
/>
<button type="button" className="btn btn-success" onClick={this.onSubmit}>Comment</button>
</form>
);
}
