Web/API/Element/toggleAttribute

From Get docs


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

Element.toggleAttribute(name [, force]);

Parameters

name
A DOMString 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 to determine whether the attribute should be added or removed, no matter whether the attribute is present or not at the moment.

Return value

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

Exceptions

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

Example

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

HTML

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

JavaScript

var button = document.querySelector("button"); 
var input = document.querySelector("input"); 

button.addEventListener("click", function(){
  input.toggleAttribute("readonly");
});
