[javascript] Unable to preventDefault inside passive event listener

I'm using Framework7 sortable list and it works well, just that it doesn't trigger an event when the list is changed.

So I'm trying a few built-in events:

$('.sortable-handler').on('touchstart', function (e) {
    e.preventDefault();
    alert('touchstart');
});

$('.sortable-handler').on('touchmove', function (e) {
    e.preventDefault();
    console.log('touchmove');
});

$('.sortable-handler').on('touchcancel', function (e) {
    e.preventDefault();
    console.log('touchcancel');
});

$('.sortable-handler').mouseleave(function (e) {
    e.preventDefault();
    console.log('mouseleave');
});

.. but all I get is:

Unable to preventDefault inside passive event listener due to target being treated as passive. See https://www.chromestatus.com/features/5093566007214080

Which event should I look for to get the updated list on every sort?

I am getting this issue when using owl carousal and scrolling the images.

So get solved just adding below CSS in your page.

.owl-carousel {
-ms-touch-action: pan-y;
touch-action: pan-y;
}

or

.owl-carousel {
-ms-touch-action: none;
touch-action: none;
}

See this blog post. If you call preventDefault on every touchstart then you should also have a CSS rule to disable touch scrolling like

.sortable-handler {
  touch-action: none;
}

For me

document.addEventListener("mousewheel", this.mousewheel.bind(this), { passive: false });

did the trick (the { passive: false } part).

In plain JS add { passive: false } as third argument

document.addEventListener('wheel', function(e) {
    e.preventDefault();
    doStuff(e);
}, { passive: false });

To still be able to scroll this worked for me

if (e.changedTouches.length > 1) e.preventDefault();
