Getting Started
Installing Zenscroll
Download Zenscroll and include it into your page. A good place is at the very bottom, just before the closing </body>
tag. For example:
Zenscroll will also work if you reference it in the <head>
but it is not recommended for performance reasons. Important: You can only call Zenscroll when document.body
is already available, so don’t try to call Zenscroll functions from the <head>
.
You can also get Zenscroll via npm:
Enabling native smooth-scrolling in the browser
If you want to leverage the native smooth-scrolling by the browser (currently available in Firefox 36+ and Chrome 49+) then set the scroll-behavior
CSS property to smooth
on the body and on the elements you want to scroll. E.g., Monkey money slots.
If this is set, Zenscroll will use built-in smooth-scrolling in capable browsers while still animating the scroll in older browsers. However, note that if you use the native smooth-scrolling then you loose the finer control options that Zenscroll offers: the speed settings of the animation, and the edge offset for links within the page. Only set this CSS property on the body
or on the elements if you don’t need this level of control.
Disabling automatic smoothing on local links
If you want to use Zenscroll programmatically but you don’t need the automatic smoothing on local links then set window.noZensmooth
to a non-falsy value. In this case the event handler for automatic smoothing is not installed but you can still use everything, like zenscroll.intoView()
, etc.
It’s important to set this value before Zenscroll is executed, otherwise the handlers will be installed. So make sure the setting comes before the loading of the script. For example:
(I consider the disabling of the automatic smooth-scrolling a rather rare scenario that’s why I install the event handlers by default.)
How to use
1. Automatic smooth-scroll to links within the page
Smooth Scrolling Html
If Zenscroll is included in your page it will automatically animate the vertical scrolling to anchors on the same page. No further setting is required. (Note that it can be disabled, see 1.5.)
Automatic smooth-scrolling works also with content you dynamically load via AJAX, as Zenscroll uses a generic click handler. Since the automatic smooth-scrolling is implemented a progressive enhancement, internal links work in older browsers as well.
1.1. Automatic edge offset adjustment on load
Zenscroll automatically adds the configured edge offset when the page is loaded with a hash suffix. For example, if you navigate to 'http://yoursite.com/#about'
then the scroll position will be not cut sharply at the top edge of the element with id='above'
. Instead, Zenscroll automatically adds the configured edge offset (which is 9 pixels by default, unless you changed it).
No automatic adjustment happens in the following cases:
- If automatic smooth-scroll is disabled via
noZensmooth
or the native smooth-scrolling (see 1.5) - If edge offset was set to zero (e.g.,
zenscroll.setup(null, 0)
).
1.2. Limited support for smooth back & forward navigation
The scroll is also animated when the browser’s back and forward buttons or the relevant key combinations are used (or even if the navigation is invoked from JavaScript). Note that although Zenscroll remembers the vertical scroll position, it cannot calculate changes caused by browser window resizing or collapsing/expanding elements, etc.
This functionality requires browser support for history.scrollRestoration
which is available for example in Chrome 46+, Firefox 46+, and Safari Technology Preview.
1.3. Limited support for the hashchange
event and the CSS pseudo :target
The automatic smooth-scroll on local links can also trigger the standard hashchange
event and the CSS pseudo-class :target
but only if you set the edge offset to 0. I had to introduce this limitation because otherwise the scrolling isn’t smooth. Free primavera p6 software full version with crack.
So if you need hashchange
or :target
then make sure you execute zenscroll.setup(null, 0)
.
1.4. No support for automatic scroll to elements inside scrollable elements
Zenscroll wants to be a lightweight solution for animated vertical scrolling, that works in most browsers. The automatic link-scrolling is even more focused on anchors that are directly inside the page body. Unfortunately it won’t scroll accurately to elements that are inside other scrollable elements (e.g., overflow: auto; max-height: 100px
). Don’t expect Zenscroll to re-implement the full functionality of the browser, with the recursive logic of traversing the nested scrollable elements.
So, how to deal with a situation like this? Try one of the following methods:
- Exclude the problematic links from the automatic smooth-scrolling (see 1.6.).
- Or implement the special logic programatically (see 7. Scroll inside a scrollable DIV).
- Or don’t use Zenscroll at all. Instead, rely on the browser’s built-in scrolling, and enable the native smooth-scrolling (via
body { scroll-behavior: smooth }
) which works in new browsers.
1.5. Disable the automatic smooth-scrolling
The automatic smooth-scrolling is completely disabled in the following cases:
- If you set
window.noZensmooth
to a non-falsy value (see above). - In new browsers if the
scroll-behavior
CSS property is set tosmooth
on thebody
(see above). In this case Zenscroll will only enable automatic smooth-scrolling in browsers which don’t support this feature yet (e.g., Internet Explorer).
1.6. Exclude a link from the automatic smooth-scrolling
If you want only some of the links to be excluded from the automatic smoothing then do one of the following:
- Add the class
noZensmooth
to the anchor element, for example<a href='#about'>
- Alternatively, start with the path of the page. E.g., instead of writing
<a href='#about'>
use<a href='/#about'>
or<a href='index.html#about'>
.
2. Scroll to the top of an element
Note that Zenscroll intentionally leaves a few pixels (by default 9px) from the edges of the screen or scrolling container. If you have a fixed navigation bar or footer bar then you probably need more than that. Or you may want to set it to zero. You can globally override the default value by calling zenscroll.setup()
(see below), or by providing the edgeOffset
parameter when you create a scroller for a DIV, e.g., zenscroll.createScroller(myDiv, null, 20)
3. Scroll to a specific vertical position
4. Scroll an element into view
If the element is already fully visible, with the edge offset at the top and bottom, then no scroll is performed. Otherwise Zenscroll will try to make both top & bottom of element visible, if possible. If the element is higher than the visible viewport then it will simply scroll to the top of the element, including the edge offset.
Tip: If you resize an element with a transition of 500ms, you can postpone calling zenscroll with that amount of time:
5. Scrolls the element to the center of the screen
If you want you can also define an offset. The top of the element will be upwards from the center of the screen by this amount of pixels. (By default offset is the half of the element’s height.)
Note that a zero value for offset is ignored. You can work around this by using zenscroll.toY()
.
6. Set the duration of the scroll
The default duration is 999 which is ~1 second. The duration is automatically reduced for elements that are very close. You can specifically set the duration for each scroll function via an optional second parameter. If you pass a value of zero then the scroll happends immediately, without smoothing.
Examples:
7. Scroll inside a scrollable DIV
Anything you can do within the document you can also do inside a scrollable DIV or other element. You just need to instantiate a new scroller for that element. I will also fall back by default to the native browser smooth-scrolling if available (which can be overridden via setup()
).
Important: the container DIV must have its position
CSS property set to relative
, absolute
or fixed
. If you want to keep it in the normal document flow, just assign position: relative
to it via a class or a style
attribute, like in the example below:
Obviously you can use all other scroll functions and parameters with the scrollable container. Two more examples:
8. Execute something when the scrolling is done
You can provide a callback function to all four scroll functions, which is executed when the scroll operation is finished. For example, you change some UI elements but first you want to make sure that the relevant elements are visible.
Note that the callback is immediately invoked if the native scroll-smoothing is enabled (see above).
If you look at the source code of the examples under Scroll inside a scrollable DIV they are actually implemented like this:
So first the container (with ITEM 1 to ITEM 7) is scrolled into view if necessary, and then the scrolling inside the container is performed. Try scrolling out the above container and then hit one of the ‘Play’ buttons above to see how it works.
This works with all four scrolling functions. The onDone
parameter is always the last parameter:
to(element, duration, onDone)
toY(y, duration, onDone)
intoView(element, duration, onDone)
center(element, duration, offset, onDone)
9. Change settings
It’s easy to change the basic parameters of scrolling:
- You can set the default value for duration. This will be valid for internal scrolls and all your direct scroll calls where you don’t specify a duration.
- Change the edge offset (the spacing between the element and the screen edge). If you have a fixed navigation bar or footer bar then set the offset to their height.
You can change custom scrollers similarly:
If you don’t want to change a value just omit the parameter or pass null
. For example, the line below sets the default duration, while leaving other settings unchanged:
Sets the the spacing between the edge of the screen (or a DIV) and the target element you are scrolling to, while leaving the default duration unchanged:
The function always returns the current values in an object, so even if no parameters are passed you can obtain the current settings:
10. Additional functions
To check whether a scroll is being performed right now:
To stop the current scrolling:
To get the current vertical scrolling position:
To get the top position of an element within the body or a scroller:
Impotant: the returned value is without edge offset, and without recurcursively calculating nested scrollable containers.
