### Downloading Manually

If you want the latest stable version, get the latest release from the [releases page](https://github.com/flesler/jquery.scrollTo/releases).

## 2.0

Version 2.0 has been recently released. It is mostly backwards compatible, if you have any issue first check [this link](https://github.com/flesler/jquery.scrollTo/wiki/Migrating-to-2.0).

If your problem is not solved then go ahead and [report the issue](https://github.com/flesler/jquery.scrollTo/issues/new).

## Usage

jQuery.scrollTo's signature is designed to resemble [$().animate()](http://api.jquery.com/animate/).

```js

$(element).scrollTo(target[,duration][,settings]);

```

### _element_

This must be a scrollable element, to scroll the whole window use `$(window)`.

### _target_

This defines the position to where `element` must be scrolled. The plugin supports all these formats:

 * A number with a fixed position: `250`

 * A string with a fixed position with px: `"250px"`

 * A string with a percentage (of container's size): `"50%"`

 * A string with a relative step: `"+=50px"`

 * An object with `left` and `top` containining any of the aforementioned: `{left:250, top:"50px"}`

 * The string `"max"` to scroll to the end.

 * A string selector that will be relative to the element to scroll: `".section:eq(2)"`

 * A DOM element, probably a child of the element to scroll: `document.getElementById("top")`

 * A jQuery object with a DOM element: `$("#top")`

### _settings_

The `duration` parameter is a shortcut to the setting with the same name.

These are the supported settings:

 * __axis__: The axes to animate: `xy` (default), `x`, `y`, `yx`

 * __interrupt__: If `true` will cancel the animation if the user scrolls. Default is `false`

 * __limit__: If `true` the plugin will not scroll beyond the container's size. Default is `true`

 * __margin__: If `true`, subtracts the margin and border of the `target` element. Default is `false`

 * __offset__: Added to the final position, can be a number or an object with `left` and `top`

 * __over__: Adds a % of the `target` dimensions: `{left:0.5, top:0.5}`

 * __queue__: If `true` will scroll one `axis` and then the other. Default is `false`

 * __onAfter(target, settings)__: A callback triggered when the animation ends (jQuery's `complete()`)

 * __onAfterFirst(target, settings)__: A callback triggered after the first axis scrolls when queueing

You can add any setting supported by [$().animate()](http://api.jquery.com/animate/#animate-properties-options) as well:

 * __duration__: Duration of the animation, default is `0` which makes it instantaneous

 * __easing__: Name of an easing equation, you must register the easing function: `swing`

 * __fail()__: A callback triggered when the animation is stopped (f.e via `interrupt`)

 * __step()__: A callback triggered for every animated property on every frame

 * __progress()__: A callback triggered on every frame

 * And more, check jQuery's [documentation](http://api.jquery.com/animate/#animate-properties-options)

### window shorthand

You can use `$.scrollTo(...)` as a shorthand for `$(window).scrollTo(...)`.

### Changing the default settings

As with most plugins, the default settings are exposed so they can be changed.

```js

$.extend($.scrollTo.defaults, {

  axis: 'y',

  duration: 800

});

```

### Stopping the animation

jQuery.scrollTo ends up creating ordinary animations which can be stopped by calling [$().stop()](http://api.jquery.com/stop/) or [$().finish()](http://api.jquery.com/finish/) on the same element you called `$().scrollTo()`, including the `window`.

Remember you can pass a `fail()` callback to be called when the animation is stopped.

### onAfter and requestAnimationFrame

jQuery.scrollTo has a `onAfter` callback for work that runs after the animation finishes. It will be called before the `scroll` event fires. To combat this you can use  [requestAnimationFrame](http://caniuse.com/#feat=requestanimationframe) to do work on the next tick. It is available in many browsers, but you may want to [polyfill](https://github.com/chrisdickinson/raf) for the few it does not support.

```js

$.scrollTo(100, {

  onAfter: function() {

    requestAnimationFrame(function() {

        $(".result").addClass("selected");

    });

  }

});

```

## Demo

Check the [demo](http://demos.flesler.com/jquery/scrollTo/) to see every option in action.

## Complementary plugins

There are two plugins, also created by me that depend on jQuery.scrollTo and aim to simplify certain use cases.

### [jQuery.localScroll](https://github.com/flesler/jquery.localScroll)

This plugin makes it very easy to implement anchor navigation.

If you don't want to include another plugin, you can try using something like [this minimalistic gist](https://gist.github.com/flesler/3f3e1166690108abf747).

### [jQuery.serialScroll](https://github.com/flesler/jquery.serialScroll)

This plugin simplifies the creation of scrolling slideshows.

## Troubleshooting

- `Cannot read property 'propHooks' of undefined`: You are most likely using the slim version jQuery, which doesn't include the effects module. The plugin cannot function without it and you'll need the full version.

- **The element doesn't scroll**: A good approach to debug is to set `overflow: auto` temporarily to the scrollable element, to make sure it would be manually scrollable. If you don't see any scrollbar, the problem is likely in the HTML/CSS.
