The DOM input event is fired synchronously when the value of an <input>, <select>, or <textarea> element is changed. For input elements with type=checkbox or type=radio, the input event should fire when a user toggles the control (via touch, mouse, or keyboard) per the HTML5 specification, but historically, this has not always been the case. Check compatibility, or attach to the change event instead for elements of these types.

Additionally, the input event fires on a contenteditable editor when its contents are changed. In this case, the event target is the editing host element. If there are two or more elements which have contenteditable as true, “editing host” is the nearest ancestor element whose parent isn’t editable. Similarly, it’s also fired on the root element of designMode editors.

[1] Prior to Gecko 12.0 (Firefox 12.0 / Thunderbird 12.0 / SeaMonkey 2.9), Gecko didn't fire input events while composition was ongoing using IMEs or when dead keys were used on Mac OS X.

[2] IE 9 does not fire an input event when the user deletes characters from an input (e.g. by pressing Backspace or Delete, or using the "Cut" operation).

[3] IE 10 and IE 11 have a bug where the input event fires on placeholder attribute changes.

[4] Prior to Opera 15, Opera did not fire an input event after dropping text in an input field.

Also, the change event is related. change fires less often than input – it only fires when the changes are committed by the user.
