How do I wait until the user has finished writing down in a text input to call a function?

I'm designing a web site and I would like to be able to call a function 1 second after the last user input. I tried using onKeyUp, but it waited 1 second after the first keystroke.

Does anyone know how would this be possible?

Another similar approach, without globals:

var typewatch = function(){

    var timer = 0;

    return function(callback, ms){

        clearTimeout (timer);

        timer = setTimeout(callback, ms);

    }  

}();

...

<input type=text onKeyUp=typewatch(function(){alert('Time elapsed!');}, 1000 ); />

You can this snippet here.
