Usage

jQuery.scrollTo's signature is designed to resemble $().animate().

$(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() 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

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() or $().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 to do work on the next tick. It is available in many browsers, but you may want to polyfill for the few it does not support.
js
$.scrollTo(100, {
  onAfter: function() {
    requestAnimationFrame(function() {
        $(".result").addClass("selected");
    });
  }
});

Demo

Check the demo 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

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.

jQuery.serialScroll

This plugin simplifies the creation of scrolling slideshows.
