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 December 2018.
The validationMessage
read-only property of the HTMLSelectElement
interface returns a string representing a localized message that describes the validation constraints that the <select>
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 <select>
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;
