Is myfunction supposed to be a click event handler itself, or is it a
function that returns another function which is the click handler? You're
calling myfunction immediately, so it can't be a click handler.

That code won't work at all.
I would suggest reading the doc page on .each():
http://docs.jquery.com/Core/each#callback
But be advised that this page has several errors in it. (I'll clean it up
when I get some time if no one else gets to it first.)
If you just want the loop index, it's passed to the .each() callback as the
first parameter:
$('a').each( function( i ){
// 'i' is the loop index
$(this).click(function(){
// You can use 'i' directly in this code
});
});
But is the loop index that useful here? I'm trying to picture what you might
do with it. There may be a better way to do this - if you could say more
about your application, someone may have a suggestion.
