控制台不显示我提供的文本输入

Question

所以我正在使用 formik 在 React 中构建一个表单。我制作了一个 TextInput 组件，其中包含一个进行了一些更改的输入字段。当我使用changeHandler时，它应该更新我输入的值，但事实并非如此。我想知道是否应该对 textInput 组件进行一些更改。

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>;
  };

  /*const changeHandler = (country) => {
    setCountry(country);
  };
*/
  return (
    <div className="px-6 w-[700px]">
      <div className="grid grid-cols-1 md:grid-cold-2 gap-8">
        <TextInput
          label="First Name"
          required
          value={formik.values.firstName}
          onChange={formik.handleChange}
        >
          First name
        </TextInput>
        <TextInput
          label="Last Name"
          required
          value={formik.values.lastName}
          onChange={formik.handleChange}
        >
          Last name
        </TextInput>
        <TextInput
          label="Business Email"
          required
          info="Only business emails are allowed! No private emails adresses."

            type="submit"
            onClick={() =>
              addDoc(accountReqRef, accountReqDoc).then(() => toast)
            }
          >
            Submit
          </button>
        </div>
      </div>
    </div>

export default ContactForm;

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。
