If you mean exit the function but not stop the interval (so the function will fire again) you need to simply return from the function.

If you mean stop the interval, ie stop the function ever firing again, you need to assign a reference to the interval in a variable and then clear it when/as required.

var intie = setInterval(function() { alert('hello'); }, 5000);
clearInterval(intie);
