Check checkbox checked property using jQuery

What is the correct way of accessing a checkbox to check if it's checked? Is it necessary to first check if that element exists in the DOM and then see if is checked or not?

@Vega Given an appropriate DOMElement (which *must* exist), but not the most tidy way in jQuery. — , Oct 31 '12 at 19:07
@pst In the FM doesn't say if I first need to check if the element exists, and that was my doubt. — Hommer Smith, Nov 01 '12 at 11:16

You would use the checked selector along with the is method of Jquery

if($('#chkbox').is(':checked')){

}

You can see if the checkbox is checked by using the following condition.

   if( $("input:checked").length == 1 ) {
           //Checkbox is selected and Do stuff here
       }
