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

General info

Default Action


Property Type Description
target Read only EventTarget The event target (the topmost target in the DOM tree).
type Read only DOMString The type of event.
bubbles Read only Boolean Whether the event normally bubbles or not
cancelable Read only Boolean Whether the event is cancellable or not?


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

  • When the element is activated (by clicking or using the keyboard) for <input type="radio"> and <input type="checkbox">;
  • When the user commits the change explicitly (e.g. by selecting a value from a <select>'s dropdown with a mouse click, by selecting a date from a date picker for <input type="date">, by selecting a file in the file picker for <input type="file">, etc.);
  • When the element loses focus after its value was changed, but not commited (e.g. after editing the value of <textarea> or <input type="text">).

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 fires a change event in Gecko until the user hits Enter or switches the focus away from the <select> (see bug 126379).

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


An incomplete example, which probably doesn't work on all browsers, on jsfiddle:

Example: Change event on a select

The following code handles the change event on a <select> by calling the changeEventHandler() function in the onchange attribute. It reads the value of the event target and shows it in an alert.

<label>Choose an ice cream flavor: </label>
<select size="1" onchange="changeEventHandler(event);">

The JavaScript code is simple:

function changeEventHandler(event) {
  alert('You like ' + + ' ice cream.');

The result looks like this:
