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

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 that are not valid in attribute names. The name must have at least one character, and may not contain ASCII whitespace, NULL, /, = or > (U+0000, U+002F, U+003D, or U+003E, respectively).
