react-select focus() 更改后不显示 cursor

Question

As described in the official documentation for react-select , I'm trying to use ref and focus() to manually set the focus into the control input field. In most instances it works, but not immediately after selecting an Option from the dropdown.

After selecting an option from the dropdown, the control gets the focus but the cursor doesn't appear. It only appears if you start typing (including hitting the Esc key). On subsequent openings of the menu, the cursor appears along with the focus of the entire control field. Any ideas how to get this working?

I've created a sample code in codesandbox.io here

This is the code:

import React, { Component } from "react";
import ReactDOM from "react-dom";
import Select from "react-select";
import styled from "styled-components";

import { stateOptions } from "./data.js";

class PopoutExample extends Component {
  selectRef = React.createRef();

  state = {
    isOpen: false,
    option: undefined,
  };

  toggleOpen = () => {
  const isOpening = !this.state.isOpen;
  this.setState(
    {
      isOpen: isOpening,
    },
() => isOpening && setTimeout(() => this.selectRef.focus(), 400),
);
};

onSelectChange = option => {
  this.toggleOpen();
  this.setState({ option });
};

render() {
  const { isOpen, option } = this.state;
  return (
    <Dropdown
      target={
        <MainButton onClick={this.toggleOpen}>
          {option ? option.label : "Select a State"}
        </MainButton>
      }
    >
      <Select
        menuIsOpen
        ref={ref => {
          this.selectRef = ref;
        }}
        styles={{
          container: provided => ({
          ...provided,
          display: isOpen ? "block" : "none",
        }),
        }}
        onChange={this.onSelectChange}
        options={stateOptions}
        value={option}
        controlShouldRenderValue={false}
      />
    </Dropdown>
  );
}
}

const MainButton = styled.button`
  padding: 10px;
  background-color: aqua;
  width: 100%;
`;

const Dropdown = ({ children, target }) => (
  <div>
    {target}
    {children}
  </div>
);

ReactDOM.render(<PopoutExample />, document.getElementById("root"));

Answer 1

You can notice that the bug also exists in the official react-select examples . Even clicking on the blur button after the selection is not solving the problem.

There's probably a small different in the code when user closes the menu and saves + automatically closes action.

I saw you've opened an issue on github. Let's keep an eye on it.

If I can offer an alternative to the behaviour you're trying to achieve, instead of hiding the Select with css why don't just mount / unmount it?

class PopoutExample extends Component {
  state = {
    isOpen: false,
    option: undefined
  };

  toggleOpen = () => {
    this.setState({
      isOpen: !this.state.isOpen
    });
  };

  onSelectChange = option => {
    this.setState({ option, isOpen: !this.state.isOpen });
  };

  render() {
    const { isOpen, option } = this.state;
    return (
      <Dropdown
        target={
          <MainButton onClick={this.toggleOpen}>
            {option ? option.label : "Select a State"}
          </MainButton>
        }
      >
        {isOpen && (
          <Select
            autoFocus
            menuIsOpen
            onChange={this.onSelectChange}
            options={stateOptions}
            value={option}
            controlShouldRenderValue={false}
          />
        )}
      </Dropdown>
    );
  }
}

Here alive example of my solution.
