## 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.
## 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.
