HTMLElement: change event

The change event is fired for <input>, <select>, and <textarea> elements when an alteration to the element's value is committed by the user. Unlike the input event, the change event is not necessarily fired for each alteration to an element's value.

Depending on the kind of element being changed and the way the user interacts with the element, the change event fires at a different moment:

The HTML specification lists the <input> types that should fire the change event.

Examples

<select> element

HTML

<label>Choose an ice cream flavor:
  <select class="ice-cream" name="ice-cream">
    <option value="">Select One …</option>
    <option value="chocolate">Chocolate</option>
    <option value="sardine">Sardine</option>
    <option value="vanilla">Vanilla</option>
  </select>
</label>

<div class="result"></div>

JavaScript

const selectElement = document.querySelector('.ice-cream');

selectElement.addEventListener('change', (event) => {
  const result = document.querySelector('.result');
  result.textContent = `You like ${event.target.value}`;
});

Result

Text input element

For some elements, including <input type="text">, the change event doesn't fire until the control loses focus. Try entering something into the field below, and then click somewhere else to trigger the event.

HTML

<input placeholder="Enter some text" name="name"/>
<p id="log"></p>

JavaScript

const input = document.querySelector('input');
const log = document.getElementById('log');

input.addEventListener('change', updateValue);

function updateValue(e) {
  log.textContent = e.target.value;
}

Result

Browser compatibility

No compatibility data found. Please contribute data for "api.HTMLElement.change_event" (depth: 1) to the MDN compatibility data repository.

Different browsers do not always agree whether a change event should be fired for certain types of interaction. For example, keyboard navigation in <select> elements never fired a change event in Gecko until the user hit Enter or switched the focus away from the <select> (see bug 126379). Since Firefox 63 (Quantum), this behavior is consistent between all major browsers, however.
