ElementInternals: reportValidity() method

Baseline 2023
Newly available

Since March 2023, this feature works across the latest devices and browser versions. This feature might not work in older devices or browsers.

Syntax

js
reportValidity()

Parameters

None.

Return value

A boolean value, true if the element meets all validation constraints.

Exceptions

NotSupportedError DOMException

Thrown if the element does not have its formAssociated property set to true.

Examples

In the following example ElementInternals.setValidity() is used to indicate that the element does not meet validation rules. Calling reportValidity() returns false, and the value "my message" is sent to the user agent for display.

After calling setValidity again, this time indicating that all rules are marked false, reportValidity() returns true.

js
let element = document.getElementById("join-checkbox");
element.internals_.setValidity({ valueMissing: true }, "my message");
console.log(element.internals_.reportValidity()); / false
element.internals_.setValidity({});
console.log(element.internals_.reportValidity()); / true
