J'ai le code ci-dessous

                   <Autocomplete
                        id='combo-box-demo'
                        options={companies}
                        getOptionLabel={getOptionLabel}
                        renderInput={params => (
                            <TextField {...params} variant='outlined' />
                        )}
                        onChange={(event, newValue) => onCompanyChange(event, newValue)}
                    />

Je souhaite personnaliser la fonction lorsque j'ai cliqué sur le bouton Effacer dans l'entrée de saisie semi-automatique. Je dois demander à l'utilisateur s'il veut vraiment effacer le champ en premier. Est-il possible de cibler le .MuiAutocomplete-clearIndicator afin que je puisse y ajouter plus de fonctions ? Merci d'avance !

Vous pouvez suivre ce code, bien que j'affiche une alerte vous pouvez faire un modal et le montrer si vous le souhaitez

CODE:

import React from "react";
import TextField from "@material-ui/core/TextField";
import Autocomplete from "@material-ui/lab/Autocomplete";

export default function ComboBox() {
  setTimeout(async () => {
    const close = await document.getElementsByClassName(
      "MuiAutocomplete-clearIndicator"
    )[0];
    close.addEventListener("click", () => {
      alert("Really, clear the input");
    });
  }, 100);

  return (
    <Autocomplete
      id="combo-box-demo"
      options={top100Films}
      getOptionLabel={(option) => option.title}
      style={{ width: 300 }}
      renderInput={(params) => (
        <TextField {...params} label="Combo box" variant="outlined" />
      )}
    />
  );
}

Si vous voulez un modal propre, au lieu d'alerte, vous pouvez définir le modal pour qu'il soit visible dans le deuxième argument de close.addEventListener (c'est la fonction elle-même)
