Envoking functions besides in a form or in Custom Actions

Envoking functions besides in a form or in Custom Actions

I haven't yet experimented with getting this to work. 

However, before I "commit" to building a full html view of a view I want to know if there ways of envoking funtions through an html form button or a html link...  VS the normal way of having custom actions in your view. 

Any thoughts? 

Thank you for your help.
