HTMLObjectElement: checkValidity() method
The checkValidity() method of the HTMLObjectElement interface checks if the element is valid, but always returns true because <object> 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("myObjectElement");
console.log(element.checkValidity());
