Posting same form to different actions depending on button clicked

Question

I have a similar post on this on StackOverflow but perhaps my misunderstanding is more substantial. I have an action Index() and an Index view its rendering. From Index()

Additional to accepted answer when you are in need to change action as well as Controller too:

$('#go_button').click(function() {
    $('form').attr("action", "@("Search","OtherControllerName")");  //change the form action
    $('form').submit();  // submit the form
});
