Smooth Scroll Plugin

-

Features

$.fn.smoothScroll

+

Smooth Scroll Plugin

+

Allows for easy implementation of smooth scrolling for same-page links.

+

+

Note: Version 2.0+ of this plugin requires jQuery version 1.7 or greater.

+

Download

+

Using npm:

+

1
npm install jquery-smooth-scroll
+

+

The old-fashioned way:

+

Go to the following URL in your browser and copy/paste the code into your own file: +https://raw.githubusercontent.com/kswedberg/jquery-smooth-scroll/master/jquery.smooth-scroll.js

+

Demo

+

You can try a bare-bones demo at kswedberg.github.io/jquery-smooth-scroll/demo/

Features

$.fn.smoothScroll

-
• Allows for easy implementation of smooth scrolling for same-page links.
• Works like this: $('a').smoothScroll();
• Specify a containing element if you want: $('#container a').smoothScroll();
• Exclude links if they are within a containing element: $('#container a').smoothScroll({excludeWithin: ['.container2']});
• Exclude links if they match certain conditions: $('a').smoothScroll({exclude: ['.rough','#chunky']});
• Adjust where the scrolling stops: $('.backtotop').smoothScroll({offset: -100});
-
• Add a callback function that is triggered before the scroll starts: `$('a').smoothScroll({beforeScroll: function() { alert('ready to go!'); }});
+
• Add a callback function that is triggered before the scroll starts: $('a').smoothScroll({beforeScroll: function() { alert('ready to go!'); }});
• Add a callback function that is triggered after the scroll is complete: $('a').smoothScroll({afterScroll: function() { alert('we made it!'); }});
-
• Add back button support by including a history management plugin such as Ben Alman's BBQ. See demo/bbq.html for an example of how to implement this.
+
• Add back button support by using a hashchange event listener. You can also include a history management plugin such as Ben Alman's BBQ for ancient browser support (IE < 8), but you'll need jQuery 1.8 or earlier. See demo/hashchange.html or demo/bbq.html for an example of how to implement.

  // The higher this number, the faster the scroll speed
  autoCoefficient: 2,
 
  // $.fn.smoothScroll only: whether to prevent the default click action
  preventDefault: true
 
}
+

The options object for $.fn.smoothScroll can take two additional properties: exclude and excludeWithin. The value for both of these is an array of selectors, DOM elements or jQuery objects. Default value for both is an empty array.

Setting options after initial call

+

If you need to change any of the options after you've already called .smoothScroll(), +you can do so by passing the "options" string as the first argument and an +options object as the second.

$.smoothScroll

• Utility method works without a selector: $.smoothScroll()
-
• Can be used to scroll any element (not just document.documentElement / -document.body)
+
• Can be used to scroll any element (not just document.documentElement / document.body)

• Doesn't automatically fire, so you need to bind it to some other user interaction. For example:

  -

    $('button.scrollsomething').on('click', function() {
  -    $.smoothScroll({
  -      scrollElement: $('div.scrollme'),
  -      scrollTarget: '#findme'
  -    });
  -    return false;
  -  });

      scrollTarget: '#findme'
    });
    return false;
  });
  +

• The $.smoothScroll method can take one or two arguments.

  -
  • If the first argument is a number, the document is scrolled to that +
  • If the first argument is a number or a "relative string," the document is scrolled to that position. If it's an options object, those options determine how the document (or other element) will be scrolled.
  -
  • If a number is provided as the second argument, it will override whatever may have been set for the scrollTarget option.
  +
  • If a number or "relative string" is provided as the second argument, it will override whatever may have been set for the scrollTarget option.
  +
  • The relative string syntax, introduced in version 2.1, looks like "+=100px" or "-=50px" (see below for an example).

Additional Option

The following option, in addition to those listed for $.fn.smoothScroll above, is available for $.smoothScroll:

-

{
-  // jQuery set of elements you wish to scroll.
-  //  if null (default), $('html, body').firstScrollable() is used.

Note:

+

If you use $.smoothScroll, do NOT use the body element (document.body or $('body')) alone for the scrollElement option. Probably not a good idea to use document.documentElement ($('html')) by itself either.

+

$.fn.scrollable

• Selects the matched element(s) that are scrollable. Acts just like a DOM traversal method such as .find() or .next().

• Uses document.scrollingElement on compatible browsers when the selector is 'html' or 'body' or 'html, body'.

Notes

+

Examples

+

Scroll down one "page" at a time (v2.1+)

+

With smoothScroll version 2.1 and later, you can use the "relative string" syntax to scroll an element or the document a certain number of pixels relative to its current position. The following code will scroll the document down one page at a time when the user clicks the ".pagedown" button:

+

1
2
3
$('button.pagedown').on('click', function() {
  $.smoothScroll('+=' + $(window).height());
});
+

+

Smooth scrolling on page load

+

If you want to scroll to an element when the page loads, use $.smoothScroll() in a script at the end of the body or use $(document).ready(). To prevent the browser from automatically scrolling to the element on its own, your link on page 1 will need to include a fragment identifier that does not match an element id on page 2. To ensure that users without JavaScript get to the same element, you should modify the link's hash on page 1 with JavaScript. Your script on page 2 will then modify it back to the correct one when you call $.smoothScroll().

+

For example, let's say you want to smooth scroll to <div id="scrolltome"></div> on page-2.html. For page-1.html, your script might do the following:

+

1
2
3
4
5
$('a[href="page-2.html#scrolltome"]').attr('href', function() {
  var hrefParts = this.href.split(/#/);
  hrefParts[1] = 'smoothScroll' + hrefParts[1];
  return hrefParts.join('#');
});
+

+

Then for page-2.html, your script would do this:

+

1
2
3
4
5
6
7
8
// Call $.smoothScroll if location.hash starts with "#smoothScroll"
var reSmooth = /^#smoothScroll/;
var id;
if (reSmooth.test(location.hash)) {
  // Strip the "#smoothScroll" part off (and put "#" back on the beginning)
  id = '#' + location.hash.replace(reSmooth, '');
  $.smoothScroll({scrollTarget: id});
}
+

+

Focus element after scrolling to it.

+

Imagine you have a link to a form somewhere on the same page. When the user clicks the link, you want the user to be able to begin interacting with that form.

+

+

• As of smoothScroll version 2.2, the plugin will automatically focus the element if you set the autoFocus option to true.

  +

  1
  2
  3
  $('div.example').smoothScroll({
    autoFocus: true
  });
  +

  +
+

• In the future, versions 3.x and later will have autoFocus set to true by default.

  +
+
• If you are using the low-level $.smoothScroll method, autoFocus will only work if you've also provided a value for the scrollTarget option.
+
• Prior to version 2.2, you can use the afterScroll callback function. Here is an example that focuses the first input within the form after scrolling to the form:
+

+

1
2
3
4
5
$('a.example').smoothScroll({
  afterScroll: function(options) {
    $(options.scrollTarget).find('input')[0].focus();
  }
});
+

+

For accessibility reasons, it might make sense to focus any element you scroll to, even if it's not a natively focusable element. To do so, you could add a tabIndex attribute to the target element (this, again, is for versions prior to 2.2):

+

$('div.example').smoothScroll({

    if (!$tgt.is(document.activeElement)) {
      $tgt.attr('tabIndex', '-1');
      $tgt[0].focus();
    }
  }
});
