oninput event

DOM 事件 InputEvent

Definition and Usage

The oninput event occurs when the element receives user input.

This event occurs when the value of the <input> or <textarea> element changes.

Tip：This event is similar to onchange ɗanar。Difference is that the oninput event occurs immediately after the element value changes, while onchange occurs when the element loses focus and the content changes. Another difference is that the onchange event also applies to <select> elements.
