A jQuery plugin that adds cross-browser mouse wheel support.

In order to use the plugin, simply bind the mousewheel event to an element. It also provides two helper methods called mousewheel and unmousewheel that act just like other event helper methods in jQuery. The event callback receives three extra arguments which are the normalized "deltas" of the mouse wheel.

Here is an example of using both the bind and helper method syntax.

// using bind
$('#my_elem').bind('mousewheel', function(event, delta, deltaX, deltaY) {
    console.log(delta, deltaX, deltaY);
});

// using the event helper
$('#my_elem').mousewheel(function(event, delta, deltaX, deltaY) {
    console.log(delta, deltaX, deltaY);
});

See the tests on Github.

Support for browserify is baked in.

npm install jquery-mousewheel
npm install jquery-browserify

In your server-side node.js code:

var express = require('express');
var app = express.createServer();

app.use(require('browserify')({
    require : [ 'jquery-browserify', 'jquery-mousewheel' ]
}));

In your browser-side javascript:

var $ = require('jquery-browserify');
require('jquery-mousewheel')($);
