Tweening empty jQuery elements

[G. Scott]

Hi!

 

In the example below, I'm wondering if its ok if you try to tween myElement if the selector found no elements to match?

 var myElement = $(div).find('.foundit');

Typically I check to be sure the element exists with something like...

if(myElement.length > 0){...

before I would tween it. But in a project I am currently working on, I realized that I forgot to do this, yet no errors are being thrown when the element is empty. So maybe I have been adding the conditional statement unnecessarily?

 

Thanks for your thoughts!

It's generally not a good idea to tween a null object, and you will get errors if you literally try to just pass null in as the target (or a variable that resolves to null), but in the case of selector text, since it still returns a wrapper of some kind (like a NodeList or jQuery object), it's technically not null so it doesn't throw errors.

Thanks for the reply! Yes, thats what I suspected. I'll continue checking since I think thats really the correct way to go... even though it doesn't break anything if I don't. As always, GSAP rocks! THANKS!
