HTMLFieldSetElement: checkValidity() method

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since December 2018.

The checkValidity() method of the HTMLFieldSetElement interface checks if the element is valid, but always returns true because <fieldset> elements are never candidates for constraint validation.

Note: The :valid and :invalid CSS pseudo-classes are applied to <fieldset> elements based on the validity of its descendant form controls, not the fieldset itself.

Syntax

js
checkValidity()

Parameters

None.

Return value

A boolean value, true.

Examples

In the following example, calling checkValidity() returns true.

console.log(element.checkValidity());
