# jQuery Mouse Wheel Plugin

A [jQuery](http://jquery.com/) 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:

```js
// using bind
$('#my_elem').on('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 it in action
[See the tests on Github](http://brandonaaron.github.io/jquery-mousewheel/test).

## Using with [Browserify](http://browserify.org)

Support for browserify is baked in.

```bash
npm install jquery-mousewheel
npm install jquery-browserify
```

In your server-side node.js code:

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

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

In your browser-side javascript:

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