angular-wheelie

angular-wheelie exposes a service that allows you to bind wheel events to an angular element.

Installation

Install with bower:

bower install angular-wheelie

Or with npm:

npm install angular-wheelie

Or simply download the latest release.

Usage

The pre-built files can be found in the dist/ directory. dist/angular-wheelie.min.js is minified and production-ready. Example usage:

<script src="dist/angular-wheelie.min.js"></script>

Add wheelie to your app's module dependencies:

angular.module('myapp', ['wheelie']);

And now you can use the wheelie service in your controllers, directives, services etc. Example usage in a controller:

app.controller('MyController', [ '$scope', 'wheelie', function ($scope, wheelie) {
    var target = angular.element('#someElement');
    // To listen for wheel events:
    wheelie.bind(target, {
        up: function (event) {
            console.log('wheel up on element #someElement!');
            // to prevent scrolling, use event.preventDefault();
        },
        right: function (event) { // i.e. with a trackpad
            console.log('wheel right on element #someElement!');
        },
        down: function (event) {
            console.log('wheel down on element #someElement!');
        },
        left: function (event) { // i.e. with a trackpad
            console.log('wheel left on element #someElement!');
        }
    });
    // To unbind:
    $scope.on('$destroy', function () {
        wheelie.unbind(target);
    });
}]);

Not all callbacks are required, but at least one must be provided.

In the above example, all wheel events from #someElement will trigger one of the callbacks. To ignore wheel events from a nested element, pass the nested element's class-name as the third parameter:

app.controller('MyController', [ '$scope', 'wheelie', function ($scope, wheelie) {
    var target = angular.element('#someElement');
    var callbacks = { /* up, right, down, left callbacks */ };
    var classNameToIgnore = 'some-nested-elements';
    wheelie.bind(target, callbacks, classNameToIgnore);
}]);
