Prevent iOS 11.3 overflow bouncing

ios, ios11.3, javascript, jquery, mobile-safari

Solution

It was caused by a bug of WebKit. Bug 182521

Try

window.addEventListener("touchstart", function(event) {
  event.preventDefault();
}, {passive: false});

as a workaround.

Problem

I've been making use of the `preventDefault` technique on the `touchmove` event since now, when I noticed it doesn't seem to work anymore on iOS 11.3, for neither Safari, nor Chrome or Firefox: ``` document.ontouchmove = function(event){ event.preventDefault(); } ``` Has anything changed now in iOS? What's the way of preventing the bouncing at the top or end of the page? Reproduction online Reproduction online with jQuery Video here:
