jquery - Dont execute javascript again for 1 second, even if trigger is re-triggered -

im detecting scrolling on page , executing code when use scrolls or down. problem code firing multiple times quickly. need code once executed not able execute again 1 second.

ideally execution disabled 1 second. if //do has fired, cant fire again 1 second , neither can //do else

note - know isnt reliable cross browser fine moment. doenst need work touchscreen scrolling.

$(document).ready(function(){     $('body').bind('mousewheel', function(e){         if(e.originalevent.wheeldelta /120 > 0) {             //do         }         else{             //do else          }     }); }); 

ive tried using timeout function seems wait , fire multiple times, rather once:

settimeout(function() {     //do      event.stoppropagation(); }, 1000); 

have debounce / throttle. there's popular jquery plug-in written ben alman provides sort of functionality. see underscore.

debounce or throttle? docs:

well, put simply: while throttling limits execution of function no more once every delay milliseconds, debouncing guarantees function ever executed single time (given specified threshhold).
