Is there a way of checking a draggable instance of a div exists?


I'm using kill() for something but it is throwing an error if I try and kill something that's not there, so my question is, can i check for the draggable without getting an error?

Did you mean check if your element exists before killing it?

You could do something like this to check if element exists first

var $element = document.getElementById("box");

if($element.length > 0){
    // place kill() code here
    console.log("#box exists in DOM");

You would use the length property


Hope this helps!

Thanks Jonathan,


it's not the element I need to check for, it's whether it has a draggable assigned to it... ideally I'd keep a track on them all but hoping there is a simple way to just check if the draggable exists first as it's not a certainty that some items are draggable.

Im sure Jack and Carl could give a better answer regarding checking if your Draggable instance exists.


But in the meantime .. Have you tried checking if it is an object:


var myDraggable;

// instance does not exist - outputs 'undefined' 

// create GSAP Draggable instance
myDraggable = Draggable.create("#yourID", {

// do some code stuff here

// check if myDraggable instance is an object
if(typeof myDraggable === 'object'){
    // instance exists
    console.log("myDraggable instance exists");


If this doesn't help could you please provide a limited example of what your are seeing in a codepen example. This way we can better help you by seeing your code in context.

I'm such an idiot... I'd done this... and it wasn't working... turned out I was typing 'underfined'


if (typeof Draggable.get($(tempClip))!='undefined'){
