events - How to get a Boolean return value from jQuery trigger method? -

i have custom event want fire using jquery's trigger method:

$(wizard).trigger('validatingstepvalues'); 

then in wizard's current step code, subscribe event follow:

$(wizard).bind('validatingstepvalues', function (){     // validating step's form data here; returning false on invalid state. }); 

then in wizard, again want able stop user going next step, if false value returned validation process? i'd have like:

$(wizard).trigger('validatingstepvalues', validreturncallback, invalidreturncallback) 

have considered using like:

function wizardvalidator(successcallback, failurecallback) {     return function() {          // validating step's form data here;          if (wasvalid && successcallback) {             successcallback();         }          else if (! wasvalid && failurecallback) {             failurecallback();         }          return wasvalid;     }; }  $(wizard).bind('validatingstepvalues', wizardvalidator(validreturncallback, invalidreturncallback)); 

this requires know callbacks want use @ time bind event listener. if want able use different callback functions @ different times, define additional event types, like:

$(wizard).bind('validatingstep2values', wizardvalidator(validstep2returncallback, invalidstep2returncallback)); $(wizard).bind('validatingstep3values', wizardvalidator(validstep3returncallback, invalidstep3returncallback)); 

alternately, events create calling trigger() propagate dom hierarchy. returning false event handler cancels propagation. bind desired success callback function event listener on wizard's parent node. won't allow failure callback executed, however.
