A jQuery plugin to make background images draggable.
NOTE: I don't plan to maintain this library anymore since I've moved on from jQuery. There seems to be requests for supporting different options for background-size or different units for background-position. After looking at the css spec for these properties, it seems unmaintainable to support every possible configuration, so I would encourage you to fork this and shape it to your specific needs.
| Option | Type | Known Values | Default Value | Description |
|---|---|---|---|---|
| bound | Boolean | true|false | true | Whether dragging is bounded by the edges of the image. |
| axis | String | x|y | If specified, restrict dragging along x or y axis. | |
| done | Function | Called when dragging is stopped by mouseup, touchup, or mouseleave. |
// default options
$('div').backgroundDraggable();
// only draggable in the x direction, and dragging is not bounded by the image
$('div').backgroundDraggable({ bound: false, axis: 'x' });
// disable draggable background
$('div').backgroundDraggable('disable');
// callback when drag complete
$('div').backgroundDraggable({
done: function() {
backgroundPosition = $('div').css('background-position');
console.log(backgroundPosition);
}

IE9+. Only background-size value of auto (default) and cover are supported. background-position must be absolute pixels. There will be bugs if you use center for percentages.
