Question

How can I force any change to a checkbox (inside a form) or to a drop-down menu selection to cause a HTTP POST to be issued by the browser?

Bandwidth is not an issue, page reloading is not an issue and I don’t want to go the full AJAX route.

What I really want is an HTTP POST to be done when the user clicks on a checkbox (or selects something from a drop-down menu), etc. without the user having to click ‘Submit’ after its change.

Maybe it should be done with some JavaScript on the client-side? (I couldn’t succesfully Google anything)

Use Javascript. Add onchange="document.getElementById('myFormId').submit()" to the elements, or do this programatically. myFormId must be replaced by the HTML id of the form element.
