keyup function with delay

This code will execute a function after the user has stopped typing for a time of 1000ms. Hence the function will not be called on each keyup event. Great!!!

 jQuery(function(){ var delay = (function(){ var timer = 0; return function(callback, ms){ clearTimeout (timer); timer = setTimeout(callback, ms); }; })(); $('input').keyup(function() { delay(function(){ alert('Time elapsed!'); }, 1000 ); }); });
