HTML oninput Event Attribute

Last Updated : 04 Aug, 2023

This attribute works when it gets user input value. This attribute mainly fires when the user change the value of <input> and <textarea> element. This attribute is quite similar to onchange attribute but the basic difference is that the oninput event attribute occurs immediately when the value of the element changes while the onchange attribute occurs when the element loses Focus. The other difference is that onchange attribute also works with the <select> element.

Supported Tags:

<input type="password">
<input type="search">
<input type="text">
<textarea>

Syntax:

<element oninput = "script">

Attribute Value: This attribute contains value script and it works when oninput event triggered. This attribute is supported by many HTML tags: <input type="password">, <input type="search">, <input type="text"> and <textarea>.
