jQuery check if item is currently selected

jQuery code snippets to check if element is selected (could be used to check if input is focused as well).

//this is one way to do it

//this is another way
function itemHasFocus(id)
    var output = false;
    //loop for all fields in the form
    $.each($('#'+id+' :input'), function(i,v)
       console.log($(this).is(":focus")); //check item has focus
       if ($(this).is(":focus"))
         output = true;
         return false; //return false skips out of the loop
    return output;
//returns true or false
