React - Material-UI - 如何在react-hook-form中使用具有多个值的Select

我正在尝试使用 UI 材质Select里面有多个选项react-hook-form没有成功。

在尝试使用多种选项之前我已经完成了这项工作

            <form onSubmit={handleSubmit(onSubmit)}>
                <Row className="mb-2">
                    <Col sm={6}>
                        <FormControl className="select-language">
                            <InputLabel> {t('Languages')}</InputLabel>
                            <Controller
                                as={
                                    <Select>
                                        {Config.languages.map(m => <MenuItem key={m.code} value={m.text}> {t(m.text)} </MenuItem>)}
                                    </Select>
                                }
                                defaultValue={user.language}
                                name="language"
                                control={control}
                            >
                            </Controller>

                        </FormControl>

                    </Col>
                </Row>
         </form>

我尝试添加multiple到 Select 元素，这导致我遇到另一个错误。

我也尝试只保留Select元素没有Controller包装器，但我无法获取语言值onSubmit

非常简单的 codeSandBox 显示我无法从中获取价值Select提交表格时：https://codesandbox.io/s/react-hook-form-example-s7h5p?file=/src/index.js https://codesandbox.io/s/react-hook-form-example-s7h5p?file=/src/index.js

我将不胜感激任何帮助 谢谢

如果有人正在寻找简单的解决方案，这可能会派上用场。现在，使用“选择组件”，多个选择选项变得非常容易。如果您查看 Select 组件，您只需将默认值设置为数组并传递“multiple”属性即可。

import {
  Button,
  FormControl,
  InputLabel,
  MenuItem,
  Select
} from "@mui/material";
import { Controller, useForm } from "react-hook-form";

const FCWidth = {
  width: "20rem"
};

export default function App() {
  const { control, handleSubmit } = useForm();
  const formSubmitHandler = (formData) => {
    console.log(formData);
  };

  const ages = ["10", "20", "30"];

  return (
    <div className="App">
      <form onSubmit={handleSubmit(formSubmitHandler)}>
        <Controller
          name="age"
          control={control}
          type="text"
          defaultValue={[]}
          render={({ field }) => (
            <FormControl sx={FCWidth}>
              <InputLabel id="age">Age</InputLabel>
              <Select
                {...field}
                labelId="age"
                label="age"
                multiple
                defaultValue={[]}
              >
                {ages.map((age) => (
                  <MenuItem value={age} key={age}>
                    {age}
                  </MenuItem>
                ))}
              </Select>
            </FormControl>
          )}
        />
        <FormControl sx={FCWidth}>
          <Button
            type="submit"
            variant="contained"
            fullWidth
            sx={{ marginTop: ".75rem", fontWeight: "bold" }}
          >
            Submit
          </Button>
        </FormControl>
      </form>
    </div>
  );
}
