How to resolve the issue of any data type in Material UI's Textfield

I am seeking clarity on how to resolve the TypeScript error indicating that an element has an 'any' type, and how I can determine the appropriate type to address my issue. Below is a snippet of my code:

import { MenuItem, TextField } from '@mui/material';
import { useQuery } from '@tanstack/react-query';
import { Categories } from '../api/agent';
import { ICategory } from '../models/ApiInterface';

const CategorySelect = ({ handleCategoryChange }) => {
  const { data, isLoading, isError } = useQuery<ICategory[]>(
    ['categories'],
    Categories.list
  );

  if (isLoading) return;

  return (
    <TextField
      fullWidth
      label="Catégorie"
      name="cyberCategory"
      onChange={handleCategoryChange}
      select
      size="small"
      value={data}
    >
      {data?.map((category) => {
        return (
          <MenuItem key={category.id} value={category.name}>
            {category.name}
          </MenuItem>
        );
      })}
    </TextField>
  );
};

export { CategorySelect };

The challenge lies with the handleCategoryChange in the props section of my arrow function, which is throwing an 'any' type error. I have attempted various solutions such as React.ChangeEvent, but I am determined to understand the correct approach.

Your assistance is greatly appreciated!

Answer №1

By examining the example titled "Controlled vs Uncontrolled" in the MUI documentation, one can learn how to correctly set up a change event handler:

  const handleChange = (event: React.ChangeEvent<HTMLInputElement>) => {
    const text = event.target.value;
    //additional code to customize the invocation of your "handleCategoryChange" function
  };

The snippet provided does not clearly demonstrate the signature of CategorySelect, therefore, adjustments may be needed to the input argument.
