如果<form>存在：

function handleEnter(event) {
  if (event.keyCode === 13) {
    const form = event.target.form;
    const index = Array.prototype.indexOf.call(form, event.target);
    form.elements[index + 1].focus();
    event.preventDefault();
  }
}
...
<form>
  <input onKeyDown={handleEnter} />
  <input onKeyDown={handleEnter} />
  <input />
</form>

没有<form>：

function useFocusNext() {
  const controls = useRef([]);

  const handler = (event) => {
    if (event.keyCode === 13) {
      // Required if the controls can be reordered
      controls.current = controls.current
        .filter((control) => document.body.contains(control))
        .sort((a, b) =>
          a.compareDocumentPosition(b) & Node.DOCUMENT_POSITION_FOLLOWING
            ? -1 : 1
        );

      const index = controls.current.indexOf(event.target);
      const next = controls.current[index + 1];
      next && next.focus();

      // IE 9, 10
      event.preventDefault();
    }
  };

  return useCallback((element) => {
    if (element && !controls.current.includes(element)) {
      controls.current.push(element);
      element.addEventListener('keydown', handler);
    }
  }, []);
};

...
const focusNextRef = useFocusNext();

<input ref={focusNextRef} />
<input ref={focusNextRef} />
<button ref={focusNextRef}>Submit</button>

您可以通过 for-in 循环使用 componentDidMount 和自动绑定引用。

http://codepen.io/jzmmm/pen/PzZgRX?editors=0010

  constructor() {
    super();
    this._handleKeyPress = this._handleKeyPress.bind(this);
  }

  // Loop through the ref's object, and bind each of them to onkeypress
  componentDidMount() {
    for (let x in this.refs) {
      this.refs[x].onkeypress = (e) => 
        this._handleKeyPress(e, this.refs[x]);
    }
  }

  // This checks ENTER key (13), then checks if next node is an INPUT
  // Then focuses next input box
  _handleKeyPress(e, field) {
    if (e.keyCode === 13) {
      e.preventDefault(); // Prevent form submission if button present
      let next = this.refs[field.name].nextSibling;

      if (next && next.tagName === "INPUT") {
        this.refs[field.name].nextSibling.focus();
      }
    }
  }

  render() {
    return (
        <form>
          <input type="text" name="name" ref='name' />
          <input type="text" name="email" ref='email' />
          <input type="text" name="zip_code" ref='zip_code' />
        </form>
    );
  }

这就是我设法使它更简单的方法：

  @autobind
  handleKeyPress(value, event){
    if(event.key === 'Enter'){
      this.refs[event].focus();
    }
  }

    <input
      onKeyPress={(event) => this.handleKeyPress('email', event)}
      ref = 'name'
    />

    <input
      onKeyPress={(event) => this.handleKeyPress('zip_code', event)}
      ref = 'email'
    />

    <input
      ref = 'zip_code'
    />

没有<form>和 TypeScript 版本。跳过禁用的输入。

const onKeyPress: React.KeyboardEventHandler<HTMLInputElement> = useCallback(
  (e) => {
    if (e.key === "Enter") {
      const inputs = Array.from(
        // Get table or tbody whatever that contains all inputs. The number of parentElements depends on the structure of your html
        e.currentTarget?.parentElement?.parentElement?.parentElement?.querySelectorAll(
          "input"
        ) ?? []
      ).filter((e) => !e.disabled)
      const index = inputs.indexOf(e.currentTarget)
      inputs[index + 1]?.focus()
      e.preventDefault()
    }
  },
  []
)

return <input type="number" onKeyPress={onKeyPress} />
