在 Material UI 中选择日期时出现 'handleChange is not a function' 错误

Question

在 DatePicker 组件中选择特定日期时，如上所述出现 'handleChange is not a function' 错误。 DatePicker 组件包装在 react-hook-form 的 Controller 组件中。预计在 DatePicker 输入上显示日期。怎么解决的？请看下面的代码：

<form noValidate autoComplete="off" onSubmit={handleSubmit(onSubmit)}>
        <Controller
          control={control}
          name="date"
          render={({ handleDateChange, selectedDate, ref }) => (
            <>
              <MuiPickersUtilsProvider utils={DateFnsUtils}>
                <Grid container justify="space-around">
                  <DatePicker
                    ref={ref}
                    value={selectedDate}
                    onChange={handleDateChange}
                    format={`d  |  ` + `MMMM  |  ` + `yyyy`}
                    disablePast
                    animateYearScrolling
                    margin="normal"
                    style={{ cursor: "pointer" }}
                  />
                </Grid>
              </MuiPickersUtilsProvider>

              <br />
            </>
          )}
          rules={{
            required: "Date is required"
          }}
        />
      </form>

首先，没有handleDateChange或selectedDate这样的属性，也许你的意思是这样的：

render={({ onChange: handleDateChange, value: selectedDate, ref }) => (

其次，您使用的是 react-hook-form v7，Controller 的 render 方法签名已更改。请参阅迁移指南 here。您需要从 field 属性获取输入道具，而不是直接从渲染道具获取：

render={({ field }) => {
  const {
    onChange: handleDateChange,
    value: selectedDate,
    ref
  } = field;

完整的工作代码：

<Controller
  control={control}
  name="date"
  render={({ field }) => {
    const {
      onChange: handleDateChange,
      value: selectedDate,
      ref
    } = field;
    return (
      <>
        <MuiPickersUtilsProvider utils={DateFnsUtils}>
          <Grid container justify="space-around">
            <DatePicker
              ref={ref}
              value={selectedDate}
              onChange={handleDateChange}
              format={`d  |  ` + `MMMM  |  ` + `yyyy`}
              disablePast
              animateYearScrolling
              margin="normal"
              style={{ cursor: "pointer" }}
            />
          </Grid>
        </MuiPickersUtilsProvider>

        <br />
      </>
    );
  }}
  rules={{
    required: "Date is required"
  }}
/>
