javascript - Jquery bug dblclick/click -

i've been experimenting jquery , have come upon problem. http://javascript.nicklewers.co.uk/nav/
on 'android' tab i've set if click once, sub menu appear, when doubleclicking, main content appear.

now problem is: double click involves 2 single clicks involves sub menu opening , closing , looks bad. how prevent this?

try (using timer know if single click or double):

alreadyclicked=false; $('#android').bind('click',function(){     var el=$(this);     if (alreadyclicked)     {         alreadyclicked=false; // reset         cleartimeout(alreadyclickedtimeout); // prevent happening         // needs happen on double click.      }     else     {         alreadyclicked=true;         alreadyclickedtimeout=settimeout(function(){             alreadyclicked=false; // reset when happens             // needs happen on single click.              // use el instead of $(this) because $(this)              // no longer element         },300); // <-- dblclick tolerance here     }     return false; });
