HTMLOutputElement: 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 HTMLOutputElement interface checks if the element is valid, but always returns true because <output> elements are never candidates for constraint validation.
Syntax
js
checkValidity()
Parameters
None.
Return value
A boolean value, true.
Examples
In the following example, calling checkValidity() returns true.
js
const element = document.getElementById("myOutput");
console.log(element.checkValidity());
