Disables scrolling from scrollbars, mousewheels, touchmoves and keypresses on a given scrollable element, typically $(window).

Use it while jQuery is animating the scroll position for a super-smooth ride!

http://jsfiddle.net/3n34qw6r/

var $window = $(window);

// Disable user scrolling just before animating scrollTop.
// Note that the `handleScrollbar` option must be false if you want to
// modify the scroll position whilst it is disabled.
$window.disablescroll({
    handleScrollbar: false
});

$("html, body").animate({ scrollTop: 500 }, "slow", function() {

    // Enable user scrolling again when animated scrolling completes
    $window.disablescroll("undo");

});

Can be passed on first use:

$element.disablescroll({
    option : value
});

The following scroll-related keys are all included by default:

If you want to toy around with the object and its prototype, you can access it at window.UserScrollDisabler.

Tested in:

• Mac: Chrome 38
• Mac: Firefox 33.1
• Mac: Safari 7.1
• Windows: IE 7-11
• Windows: Chrome 38
• Windows: Firefox 33.1
• Android: Chrome 38
• iOS 7.1 and 8.1: Safari

• Mac Safari 7.1 is a bit flickery when dragging a disabled scrollbar.
• One report of IE flickering when dragging a disabled scrollbar, although I was unable to reproduce this.
• Not sure if there is a workaround for these flickering issues, as scrolling by dragging the scrollbar does not trigger any cancellable events. This only leaves us with the option of setting the scroll position back to what it was before on every scroll event. I'm surprised this doesn't flicker in more browsers.
