Como posso obter vários valores através de uma função de retorno de chamada?

772

Estou enviando dados do filho 1 para o pai e depois para o filho 2. No momento, há três coisas que preciso enviar; valores para dia, mês e ano. Obter apenas um valor funciona bem, mas quando tento obter todos os três, recebo um TypeError.

Pai:

import Results from "./Results";
import TopForm from "./TopForm";

    const [dayValue, setDayValue] = useState("--");
    const [monthValue, setMonthValue] = useState("--");
    const [yearValue, setYearValue] = useState("--");

    return (
        <div className="font-poppins bg-light-grey p-2 h-screen w-screen">

                    // This does work but only gets the dayValue
                    callback={setDayValue}

                <Results

Podemos ver a questão do problema rastreando onde você usa o callbacksuporte em TopForm:

onClick={() => callback(dayText, monthText, yearText)}

Passar callbackcomo callback={[setDayValue, setMonthValue, setYearValue]}significa que callbacké um array e, portanto, você está tentando chamar um array como uma função incorreta.

Em vez disso, você poderia chamar as funções internas do array separadamente, como:

onClick={() => {
  callback[0](dayText)
  callback[1](monthText)
  callback[2](yearText)
}}

const { useState } = React;

function TopForm({ callback }) {
  const [error, setError] = useState(false);

  const [dayText, setDayText] = useState("");
  const [monthText, setMonthText] = useState("");
  const [yearText, setYearText] = useState("");

  const handleSubmit = (event) => {
    event.preventDefault();

    setDayText("");
    setMonthText("");
    setYearText("");
  };

  return (
    // Inputs Container

function Hero () {

  const setValues = (day, month, year) => {
    setDayValue(day);
    setMonthValue(month);
    setYearValue(year);

  const [dayText, setDayText] = useState("");
  const [monthText, setMonthText] = useState("");
  const [yearText, setYearText] = useState("");

  const handleSubmit = (event) => {
    event.preventDefault();

    setDayText("");
    setMonthText("");
    setYearText("");
  };

  return (
    // Inputs Container
    <form onSubmit={handleSubmit}>
      {/* Upper Form */}
      <div className="container flex justify-center gap-4 md:max-w-lg">
