How do I learn if events are bound to an element using jquery?

Question

I need a hasEvents() method like

var someBool = hasEvents($("#myelement"));

that returns true if there are some bound events to any of the element's event handlers.

have you taken a look at the hasEvent() plugin? the code is pretty small:

(function(A) {
    A.fn.hasEvent = function(C) {
       var B = this.data("events");
       return( B && B[C] )
    }
}) (jQuery)

for your specific purpose you could modify it slightly:

(function($) {
    $.fn.hasEvents = function() {
        return new Boolean(this.data('events') );
    }
}) (jQuery);

$('#someDiv').click(function() {
    alert('new event');
});

$('#someDiv').hasEvents();      // true
$('#someOtherDiv').hasEvents(); // false
