Search for the position:

    button: function(elem){
        return "button" === elem.type || elem.nodeName.toLowerCase() === "button";
    },
    input: function(elem){
        return /input|select|textarea|button/i.test(elem.nodeName);
    },
    //init custom
    ev: function(elem,i,match){
        var what    = $(elem).hasEvent(match[3]);
        var type    = (typeof what);
        return  what !== null && type !== undefined;
    }
    //End custom
},
setFilters: {
    first: function(elem, i){
        return i === 0;
    },
    last: function(elem, i, match, array){
        return i === array.length - 1;
    },
    even: function(elem, i){
        return i % 2 === 0;
    },

.....

same use as has()

ex:

$('form:ev(submit)');
$('input:ev(click)');
$('a:ev(click)');

It is not supported natively by jQuery, but you can write your own custom selector using hasEvent plugin :

jQuery.expr[":"].click = "jQuery(a).hasEvent('click');";

$("a:click").doStuff();

EDIT :

There is also the Event Bound Selector plugin which is more complete and works out of the box, but is also bigger.

No. You can iterate over all elements and check if they have an event binding. But that wouldn't be very efficient unless you have a clue what kind of elements would have that event binding so you can narrow the search.
