Javascript – not sure how to clear the input fields of my form after clicking select

When I press submit on my form, the data is successfully ported over to a json file however the inputs typed into each field remains visible (it does not go away like normal forms). How can I make the inputs go away after pressing submit?

this is my code I have tried various ways to amend the code including modifying the handleSubmit function but so far nothing seems to work… could appreciate any form of help. Also not too sure how to make a pop up message appear every time I press the submit button.

import React, { useState } from 'react';
import { Select, Textarea, TextInput, Button } from '@mantine/core';
import classes from './Incident.module.css';
import axios from 'axios';
import moment from 'moment';

function Incident() {
  const [loading, setLoading] = useState(false);
  const [success, setSuccess] = useState(false);


  const initialFormData = {
    student_name: '',
    student_contact_no: '',
    student_email: '',
    datetime: '',
    category: '',
    additional_info: '',
    area: ''
  };

  const [formData, setFormData] = useState({ ...initialFormData });

  const handleInputChange = (e) => {
    const { name, value } = e.target;
    setFormData({
      ...formData,
      [name]: value,
    });
  };

  const resetForm = () => {
    setFormData({ ...initialFormData });
  };
  

  const handleSubmit = async () => {
    try {
      setLoading(true); // Set loading to true while the request is in progress
      const form = new FormData()
      form.append("student_name", formData.student_name)
      form.append("student_contact_no", formData.student_contact_no)
      form.append("student_email", formData.student_email)
      form.append("datetime", moment(formData.datetime).format("YYYY-MM-DD hh:mm:ss"))
      form.append("category", formData.category)
      form.append("additional_info", formData.additional_info)
      form.append("area", formData.area)
      const response = await axios.put('/add_incident', form);
  
      if (response.status === 200) {
        // Handle success
        setSuccess(true); // Set success to true
        console.log('Incident created successfully');
        resetForm();
      } else {
        // Handle error
        console.error('Error creating incident');
      }
    } catch (error) {
      // Handle any network or request-related errors
      console.error('Network error', error);
    } finally {
      setLoading(false); // Reset loading to false regardless of success or error
    }
  };
  
  
  const inputContainerStyle = {
    display: 'flex',
    alignItems: 'center',
    justifyContent: 'space-between', // Adjust the space between input boxes
    marginBottom: '30px', // Add some vertical spacing between input sections

export default Incident;

I am using a matinee core submit button, setting the initial to ” and using

document.getElementById("student_name").value = "";
      document.getElementById("student_contact_no").value = "";
      document.getElementById("student_email").value = "";
      document.getElementById("datetime").value = "";
      document.getElementById("category").value = "";
      document.getElementById("area").value = "";
      document.getElementById("additional_info").value = ""; 

also doesn’t seem to work
