Die Konsole zeigt die von mir bereitgestellte Texteingabe nicht an

Question

Also erstelle ich ein Formular in React mit Formik. Ich habe eine TextInput-Komponente erstellt, die ein Eingabefeld mit einigen Änderungen enthält. Wenn ich changeHandler verwende, sollte der von mir eingegebene Wert aktualisiert werden, dies geschieht jedoch nicht. Ich frage mich, ob ich einige Änderungen an der textInput-Komponente vornehmen sollte.

ContactForm.jsx

import React, { useState, useMemo } from "react";
import countryList from "react-select-country-list";
import { doc, setDoc, addDoc } from "firebase/firestore";
import { accountReqRef } from "../../Firebase";
import { useFormik } from "formik";

import Alert from "../../shared/components/UIElements/Alert";
import FormSelect from "../../shared/components/UIElements/FormSelect";
import TextInput from "../../shared/components/UIElements/TextInput";

const ContactForm = () => {
  const formik = useFormik({
    initialValues: {
      firstName: "",
      lastName: "",
      email: "",
      company: "",
      jobTitle: "",
      phone: "",
      country: "",
    },
  });

  const options = useMemo(() => countryList().getData(), []);

  const toast = (
    <div className="toast toast-end">
      <div className="alert alert-info">
        <div>
          <span>New mail arrived.</span>
        </div>
      </div>
      <div className="alert alert-success">
        <div>
          <span>Message sent successfully.</span>
        </div>
      </div>
    </div>
  );

  // document submission date
  const current = new Date();
  const date = `${current.getDate()}/${
    current.getMonth() + 1
  }/${current.getFullYear()}`;

  const accountReqDoc = {
    firstName: formik.values.firstName,
    lastName: formik.values.lastName,
    email: formik.values.email,
    company: formik.values.company,
    jobTitle: formik.values.jobTitle,
    phone: formik.values.phone,
    country: formik.values.country,
    subDate: date,
    status: "pending verification",
  };
  console.log(formik);

  //add account request document to accountReq collection

  const addAccReq = () => {
    return <div>ContactForm</div>;

我的直觉是，您的输入要么缺少 id 或 name 。

这是来自文档 https://formik.org/文档/api/formik#handlechange-e-reactchangeeventany--void

例如

这样想，handleChange怎么知道哪个字段正在更新。
