How to call HTML Select the onClick event (activates a drop-down menu with options)

Question

I want to know how to fire the event of onClickany element select(html combobox element).

I tried doing $('#MySelect').click();with jQueryand tried document.getElementById('MySelect').click();using pure javascript.
