Javascript Handling Multiple Inputs with a single onchange Handler

In this tutorial, you will learn how to handle multiple input fields with one `onChange` function in JavaScript. This is useful when you want to perform some actions or validations whenever the user changes the value of any input field in a form. We will use the class name of each input field to identify which one has been changed, and use an if-else statement to show a message that the input field is updated. By the end of this tutorial, you will be able to create a simple form that handles multiple input fields with one `onChange` function.

  const inputElement = event.target;
  const inputValue = inputElement.value;
  const resultParagraph = document.getElementById('result');
  if (inputElement.classList.contains('name')) {
   resultParagraph.textContent = 'Name changed: ' + inputValue;
  } else if (inputElement.classList.contains('email')) {
   resultParagraph.textContent = 'Email changed: ' + inputValue;
