当前行为

<Formik
    isInitialValid
    initialValues={{ first_name: 'Test', email: '[email protected]' }}
    validate={validate}
    ref={node => (this.form = node)}
    onSubmitCallback={this.onSubmitCallback}
    render={formProps => {
        const fieldProps = { formProps, margin: 'normal', fullWidth: true, };
        const {values} = formProps;
        return (
            <Fragment>
                <form noValidate>
                    <TextField
                        {...fieldProps}
                        required
                        autoFocus
                        value={values.first_name}
                        type="text"
                        name="first_name"

                    />

                    <TextField
                        {...fieldProps}
                        name="last_name"
                        type="text"
                    />

                    <TextField
                        {...fieldProps}
                        required
                        name="email"
                        type="email"
                        value={values.email}

                    />
                </form>
                <Button onClick={this.onClick}>Login</Button>
            </Fragment>
        );
    }}
/>

我正在尝试此解决方案https://github.com/jaredpalmer/formik/issues/73#issuecomment-317169770但它总是让我返回Uncaught TypeError: _this.props.onSubmit is not a function

当我尝试console.log(this.form)有submitForm功能。

有解决方案的人吗？
