HTMLFieldSetElement: checkValidity() method

{{APIRef("HTML DOM")}}

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

[!NOTE] The {{cssxref(":valid")}} and {{cssxref(":invalid")}} CSS pseudo-classes are applied to <fieldset> elements based on the validity of its descendant form controls, not the fieldset itself.

Syntax

checkValidity()

Parameters

None.

Return value

A boolean value, true.

Examples

const element = document.getElementById("myFieldSet");
console.log(element.checkValidity());
