i find this: https://greensock.com/docs/#/HTML5/GSAP/TweenLite/vars/

 

and this is my code:

function tweenCompleteHandler() {
  alert("Complete!")
};

TweenLite.prototype.vars.onComplete = tweenCompleteHandler;

var animation = TweenLite.to("#box", 1, {
  x : 550
});

it didn't work? does TweenLite have something like jQuery.ajaxSetup() ?

I'm not sure why you thought altering the prototype would do that, but Diaco.AW is correct - there is no global default for setting an onComplete. It should be relatively easy for you to do that on your own, though, with a helper function. One idea:

function tween(target, duration, vars) {
    if (!vars.onComplete) {
        vars.onComplete = yourDefaultFunction;
    }
    return TweenLite.to(target, duration, vars);
}
//usage:
tween(element, 1, {x:100, y:200});

Another idea: 

function vars(values) {
    if (!values.onComplete) {
        values.onComplete = yourDefaultFunction;
    }
    return values;
}
//usage:
TweenLite.to(element, 1, vars({x:100, y:200}));

There are lots of ways you could do it.
