I am trying to add a class to a specific div, if a specific input field has a specific value. Below is my code, but it does not seem to be working. This is a dropdown select if this helps. This is built in WordPress, but the code does nothing. Please help!

Thanks in advance!

This is my input.

<input type="hidden" name="field-name-1676017181767" value="online_event">

This is my code.

$('input').change(function() {
    if($(this).val() === 'online_event') {
         $('.vue-treeselect__control').addClass("hidden");
    }
   else {
       
   }
});
