angular-disablescroll

This is a port of jquery-disablescroll by Josh Harrison from jQuery to Angular.

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

Has zero dependencies, pure Angular, no jQuery.

Demo

Example Usage

angular.module('foo', ['ElementScroll'])

.controller('fooCtrl', [
    '$scope', '$element', 'ElementScroll', 
    function($scope, $element, ElementScroll) {
        
        $scope.lockScroll = function(){
            ElementScroll.disableScrolling(angular.element($element));
        };
        
    });

Options

Can be passed on first use:

ElementScroll.disableScrolling(element, {
    option : value
})

or (granted an odd use case)

ElementScroll.enableScrolling(element, {
    option : value
})

Option	Default Value	Description
handleWheel	`true`	Boolean indicating whether to disable mouse wheels.
handleScrollbar	`true`	Boolean indicating whether to disable scroll bar dragging. Set to `false` if you need to modify the scroll position whilst scrolling is disabled.
handleKeys	`true`	Boolean indicating whether to disable scrolling triggered by keypresses, e.g. the down button.
scrollEventKeys	`[32, 33, 34, 35, 36, 37, 38, 39, 40]`	Array of scroll-related keycodes to disable during scroll. See below for reference.

Keycode Reference

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

Keycode	Key
32	Spacebar
33	Page Up
34	Page Down
35	End
36	Home
37	Left Arrow
38	Up Arrow

Known Issues (from jquery-disablescroll)

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.
