How do I trigger an onChange event for a hidden field?

Question

I want to fire an onChange event for hidden field, Most of the forums I\'ve read suggests that onChange doesn\'t work for hidden fields, So is there a way around for that,

Answer 1

In jQuery, you could trigger a custom event:

$("#hidden_input_id").trigger("special-change");

And you can listen with:

$("#hidden_input_id").on("special-change", function () {

});
