What is the best way to retrieve a value by using the data.get() method?

I am currently facing an issue with retrieving the value of a textarea that I have dynamically added to a fieldset in my form. When I attempt to submit the form, the code below is executed:

function handleSubmit(e) {
  e.preventDefault();
  console.log(document.getElementById('Observation_1').value);
  const data = new FormData(e.target);
  const value = data.get('Observation_1');
  console.log(value);
}
const form = document.querySelector('form');
form.addEventListener('submit', handleSubmit);
<form>
  <textarea id="Observation_1"></textarea><br>
  <button type="submit">Test</button>
</form>

However, after execution, console.log (value); shows null, whereas

console.log(document.getElementById('Observation_1').value);
displays the correct content of the textarea.

I would appreciate if someone could clarify why I am getting a null return and offer a solution to rectify this issue so that I can obtain the actual content of my textarea. Thank you.

Answer №1

It seems like the textarea is missing the attribute name="Observation_1".
