Jquery and trigger a click on a hidden button

Question

I have a hidden button on a form that I need to click in order to fire an asyncpostback trigger that's attached to an update panel.

How is this done?

Answer 1

$('#myHiddenButton').trigger("click");

Or just

$('#myHiddenButton').click();

See Events/Trigger

Answer 2

How about

$("#buttonid").click();
