Get value of current event handler using jQuery

I can set the onclick handler using jQuery by calling

$('#id').click(function(){
   console.log('click!');
});

Also using jQuery, how can I get a reference to the function which is currently handling the click() event?

The reason is that I have another object and want to set its click handler to the same one as #id.

Update

Thank you for all the suggestions. The problem is that I do not know which function is currently handling the clicks. Keeping track of it would add state to an already complicated template-editing system.

jQuery's .click(function) method adds the function to a queue that is executed on the click event~

So actually pulling out a reference to the given function would probably be hairy-er than you expect.

As noted by others, it would be better to pass in a reference to the function; and then you already have the reference you need.

var clicky = function () { /* do stuff */ };
$('#id').click(clicky);
// Do other stuff with clicky

Update

If you really really need to get it out, try this:

jQuery._data(document.getElementById('id')).events.click[0].handler

Depending on your version of jQuery that may or may not work~ Try playing around with

jQuery._data(document.getElementById('id'))

and see what you get.

Got the idea from this section of the source:
