HTMLSelectElement: validationMessage property
Baseline Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
The validationMessage read-only property of the HTMLSelectElement interface returns a string representing a localized message that describes the validation constraints that the control does not satisfy (if any). This is the empty string if the control is not a candidate for constraint validation (HTMLSelectElement.willValidate is false), or it satisfies its constraints.
If the element is a candidate for constraint validation (willValidate is true) and the constraints are not met (the HTMLSelectElement.validity object's valid property is false), the value is the error message that would be shown to the user during validation.
Value
A string.
Example
const select = document.getElementById("mySelect");
const errorMessage = select.validationMessage;
