HTMLFormElement: 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 HTMLFormElement
interface returns a boolean value which indicates if all associated controls meet any constraint validation rules applied to them. The method also fires an invalid
event on each invalid element, but not on the form element itself. Because there's no default browser behavior for checkValidity()
, canceling this invalid
event has no effect.
Syntax
checkValidity()
Parameters
None.
Return value
Returns true
if the associated controls' values have no validity problems; otherwise, returns false
.
Examples
In the following example, calling checkValidity()
would return true
if or false
.
const element = document.getElementById("myForm");
console.log(element.checkValidity());
