This will block vertical scrolling while dragging the image horizontally,
or prevent the horizontal pan while trying to v-scroll the page itself.
Important: Attach the event directly to the IMG element.
let blockScroll = false;
let blockPan = false;
$('.owl-carousel img').on('touchstart', '', ots);
$('.owl-carousel img').on('touchmove', '', otm);
let p0 = [0,0];
function ots(ev) { //save the first touch point
p0 = [ev.touches[0].screenX, ev.touches[0].screenY];
blockScroll = false;
blockPan = false;
}
function otm(event){
if(blockScroll)
event.preventDefault(); //don't let the window v-scroll
else if(blockPan)
{ //don't let OWL get the event and pan-x.
event.stopPropagation();
event.stopImmediatePropagation();
}
else
{ //calculate distance from the first touch point on every move
let t = event.touches[0];
let dx = t.screenX - p0[0];
let dy = t.screenY - p0[1];
if( Math.abs(dx) > Math.abs(dy) )
{
blockScroll = true;
event.preventDefault();
}
else
{
blockPan = true;
event.stopPropagation();
event.stopImmediatePropagation();
}
}
}
