simple hide element wrapper

function hideElement( elem, target ) {

    //wrap as jquery object if it isnt one
    elem = elem instanceof jQuery ? elem : $( elem );

    //if there is a target and that target is a function then run that function 
    //and return the elem to hide otherwise simply hide the element
    target ? typeof( target ) === 'function' ? ( target(elem) ).hide() : elem.find( target ).hide() : elem.hide();
}
