How to delay the .keyup() handler until the user stops typing?

Question

I’ve got a search field. Right now it searches for every keyup. So if someone types “Windows”, it will make a search with AJAX for every keyup: “W”, “Wi”, “Win”, “Wind”, “Wi

Saw this today a little late but just want to put this here in case someone else needed. just separate the function to make it reusable. the code below will wait 1/2 second after typing stop.

    var timeOutVar
$(selector).on('keyup', function() {

                    clearTimeout(timeOutVar);
                    timeOutVar= setTimeout(function(){ console.log("Hello"); }, 500);
                });
