2.0
Version 2.0 has been recently released. It is mostly backwards compatible, if you have any issue first check this link. If your problem is not solved then go ahead and report the issue.
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
andtop
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 isfalse
- limit: If
true
the plugin will not scroll beyond the container's size. Default istrue
- margin: If
true
, subtracts the margin and border of thetarget
element. Default isfalse
- offset: Added to the final position, can be a number or an object with
left
andtop
- over: Adds a % of the
target
dimensions:{left:0.5, top:0.5}
- queue: If
true
will scroll oneaxis
and then the other. Default isfalse
- 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.
$.extend($.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.
$.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.
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.
