I am not sure I fully understand the question since this is not a
web2py specific questions.
If a page has a button:
<button onclick="{{=URL(r=request,f='sayhi')}}">click me</button>
when you click it will call the action sayhi(), For example
def sayhi(): return dict(message="hello")
Normally you use <input> inside a <form>...</form>. The form is
submitted to the action specified in <form action="....">.
web2py uses postbacks, i.e. It alwys submits the form to the same
action that generated the form.
Not sure I answered your question.
