HTML oninput Attribute - HTML Attribute

Definition and Usage

The oninput attribute fires when an element gets user input.

The oninput attribute fires when the value of an <input> or <textarea> element is changed.

Tip: This event is similar to the onchange event. The difference is that the oninput event occurs immediately after the value of an element has changed, while onchange occurs when the element loses focus. The other difference is that the onchange event also works on <select> elements.

Applies to

The oninput attribute is part of the Event Attributes, and can be used on any HTML elements.
