Checkboxes in HTML forms are created using <input type = "checkbox". To disable a checkbox, use the disabled attribute in the <input> tag.

The checked attribute is a boolean attribute. When present, it specifies that an <input> element should be pre-selected (checked) when the page loads. The checked attribute can be used with <input type="checkbox"> and <input type="radio"> . The checked attribute can also be set after the page load, with a JavaScript.

The addEventListener() method can be used to apply the change event to the checkbox to validate whenever the user interacts with the checkbox.

Checking if a checkbox is checked First, select the checkbox using a DOM method such as getElementById() or querySelector() . Then, access the checked property of the checkbox element. If its checked property is true , then the checkbox is checked; otherwise, it is not.

The validation rule specifies an error condition and a corresponding error message. The error condition is written as a boolean formula expression that returns true or false. The save will be aborted and the error message will be displayed. The user can correct the error and try again.
