Close on MouseOut, Except .. Related Target

For a mouseout event, the event target is the thing you're leaving - mousing out of - the event relatedTarget is the thing you're leaving to, or entering.

        jQuery('#something').mouseout(function(e){
            /*
                don't close the subnav if we've moused out -> onto an autocomplete resultset.
            */
            var targ = e.relatedTarget, i = 0;
            //we're only checking the most recent 5 parents (ancestors).
            while(targ && ++i<5){
                //don't close the subnav if we're mousing over an autocomplete list.
                if(targ.className && targ.className.indexOf('ac_results')>-1){
                    return;
                }
                targ = targ.parentNode;
            }
            /**/
           
            //ok, close me..
            $(this).hide();
        });
