Element: toggleAttribute() method

The toggleAttribute() method of the Element interface toggles a Boolean attribute (removing it if it is present and adding it if it is not present) on the given element.

Syntax

toggleAttribute(name)
toggleAttribute(name, force)

Parameters

name

A string specifying the name of the attribute to be toggled. The attribute name is automatically converted to all lower-case when toggleAttribute() is called on an HTML element in an HTML document.

force Optional

A boolean value which has the following effects:

• if not specified at all, the toggleAttribute method "toggles" the attribute named name — removing it if it is present, or else adding it if it is not present
• if true, the toggleAttribute method adds an attribute named name
• if false, the toggleAttribute method removes the attribute named name

Return value

true if attribute name is eventually present, and false otherwise.

Exceptions

InvalidCharacterError DOMException

The specified attribute name contains one or more characters which are not valid in attribute names.

Examples

In the following example, toggleAttribute() is used to toggle the disabled attribute of an <input>.

HTML

<input value="text" /> <button>toggleAttribute("disabled")</button>

JavaScript

const button = document.querySelector("button");
const input = document.querySelector("input");
button.addEventListener("click", () => {
 input.toggleAttribute("disabled");
});
