I\'m using the scrollTo jQuery plugin and would like to know if it is somehow possible to temporarily disable scrolling on the window element through Javascript? The reason
The scroll
event cannot be canceled. But you can do it by canceling these interaction events:
Mouse & Touch scroll and Buttons associated with scrolling.
// left: 37, up: 38, right: 39, down: 40,
// spacebar: 32, pageup: 33, pagedown: 34, end: 35, home: 36
var keys = {37: 1, 38: 1, 39: 1, 40: 1};
function preventDefault(e) {
e.preventDefault();
}
function preventDefaultForScrollKeys(e) {
if (keys[e.keyCode]) {
preventDefault(e);
return false;
}
}
// modern Chrome requires { passive: false } when adding event
var supportsPassive = false;
try {
window.addEventListener("test", null, Object.defineProperty({}, 'passive', {
get: function () { supportsPassive = true; }
}));
} catch(e) {}
var wheelOpt = supportsPassive ? { passive: false } : false;
var wheelEvent = 'onwheel' in document.createElement('div') ? 'wheel' : 'mousewheel';
// call this to Disable
function disableScroll() {
window.addEventListener('DOMMouseScroll', preventDefault, false); // older FF
window.addEventListener(wheelEvent, preventDefault, wheelOpt); // modern desktop
window.addEventListener('touchmove', preventDefault, wheelOpt); // mobile
window.addEventListener('keydown', preventDefaultForScrollKeys, false);
}
// call this to Enable
function enableScroll() {
window.removeEventListener('DOMMouseScroll', preventDefault, false);
window.removeEventListener(wheelEvent, preventDefault, wheelOpt);
window.removeEventListener('touchmove', preventDefault, wheelOpt);
window.removeEventListener('keydown', preventDefaultForScrollKeys, false);
}
UPDATE: fixed Chrome desktop and modern mobile browsers with passive listeners
