HTMLElement: autocapitalize property
The autocapitalize
property of the HTMLElement
interface represents the element's capitalization behavior for user input. It is available on all HTML elements, though it doesn't affect all of them, including:
<input>
and<textarea>
elements.- Any element with
contenteditable
set on it.
autocapitalize
doesn't affect behavior when typing on a physical keyboard. It affects the behavior of other input mechanisms such as virtual keyboards on mobile devices and voice input. This can assist users by making data entry quicker and easier, for example by automatically capitalizing the first letter of each sentence.
It reflects the value of the autocapitalize
HTML global attribute.

none

<div id="ac-element" contenteditable="true" autocapitalize="default">
input here
</div>
<select id="ac-controller" type="checkbox" checked>
<option value="default">default</option>

<option value="sentences">sentences</option>
<option value="words">words</option>

>Select the capitalization behavior
const label = document.getElementById("ac-label");
const element = document.getElementById("ac-element");

controller.addEventListener("input", (e) => {
const behavior = e.target.value;

element.autocapitalize = behavior;
