I am using interact.js in my Ionic + Vue project. I have screen where there is on circle on screen when it is dragged it is cloned into parent element. Code is shown below. This works most of the time in real browser (not 100%). But on my mobile I always get this weird error and I do not understand why. I tried to figure out why and where it is comming from. I tracked bug down to this line of code :
interaction.start({ name: "drag" }, event.interactable, element);
.on('move', dragOrClone); // this function that cases error is called on this line of global interact instance
const dragOrClone = (event) => {
const { currentTarget, interaction } = event;
let element = currentTarget;
if(
interaction.pointerIsDown &&
!interaction.interacting() &&
currentTarget.style.transform === ""
) {
element = currentTarget.cloneNode(true);
element.style.position = "absolute";
element.style.left = 0;
element.style.top = 0;
element.style.width = '24px';
element.style.height = '24px';
element.style.transform = 'translate(0px, 0px)';
element.classList.remove('bg-yellow-800');
element.classList.add('bg-yellow-600');
// Adding object inside parent container element
dropzone && dropzone.appendChild(element);
position.x = 0;
position.y = 0;
// If we are moving an already existing item, we need to make sure the position object has
// the correct values before we start dragging it
}else if(
interaction.pointerIsDown &&
!interaction.interacting()
) {
updatePositionFromTransform(currentTarget);
}
// Start the drag event
interaction.start({ name: "drag" }, event.interactable, element);
};
Edit : Also this circle that is used for cloning others does not have transform value so if statement which cloned object can be true. But when I but transform on it I do not see this error but this then breaks my intention of cloning object.
