How to Toggle the :invalid State to True on a Dropdown Element Using JQuery

$("#select_id").is(':invalid')

false

Is there a way to change it to true?

$("#select_id").addClass(':invalid');
$("#select_id").prop('invalid',true)

Unfortunately, this method does not seem to work :(

Answer №1

Here is a simple solution:

You can achieve this by checking if the select element with id "select_id" is invalid using the following code:

var isValid = !$("#select_id").is(':invalid');

Initially, $("#select_id").is(':invalid') will return false, but adding the "!" operator in front of it will invert the result to true.
