    The DOM input event is fired synchronously when the value of an <input> or <textarea> element is changed. Additionally, it fires on contenteditable editors 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 root element of designMode editors.

    Opera does not fire an input event after dropping text in an input field.
    IE 9 does not fire an input event when the user removes characters from input filled by keyboard, cut, or drag operations.

    Gecko notes

    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 the Mac.

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