Smooth Scroll Plugin

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



Using npm:

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:


You can try a bare-bones demo at



  • 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 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.


The following options, shown with their default values, are available for both $.fn.smoothScroll and $.smoothScroll:

  offset: 0,

  // one of 'top' or 'left'
  direction: 'top',

  // only use if you want to override default behavior
  scrollTarget: null,

  // string to use as selector for event delegation (Requires jQuery >=1.4.2)
  delegateSelector: null,

  // fn(opts) function to be called before scrolling occurs.
  // `this` is the element(s) being scrolled
  beforeScroll: function() {},

  // fn(opts) function to be called after scrolling occurs.
  // `this` is the triggering element
  afterScroll: function() {},
  easing: 'swing',

  // speed can be a number or 'auto'
  // if 'auto', the speed will be calculated based on the formula:
  // (current scroll position - target scroll position) / autoCoeffic
  speed: 400,

  // autoCoefficent: Only used when speed set to "auto".
  // 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.


  • Utility method works without a selector: $.smoothScroll()
  • 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() {
          scrollElement: $('div.scrollme'),
          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 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.

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.
  scrollElement: null


  • Selects the matched element(s) that are scrollable. Acts just like a DOM traversal method such as .find() or .next().
  • The resulting jQuery set may consist of zero, one, or multiple elements.


  • Selects the first matched element that is scrollable. Acts just like a DOM traversal method such as .find() or .next().
  • The resulting jQuery set may consist of zero or one element.
  • This method is used internally by the plugin to determine which element to use for "document" scrolling: $('html, body').firstScrollable().animate({scrollTop: someNumber}, someSpeed)


  • To determine where to scroll the page, the $.fn.smoothScroll method looks for an element with an id attribute that matches the <a> element's hash. It does not look at the element's name attribute. If you want a clicked link to scroll to a "named anchor" (e.g. <a name="foo">), you'll need to use the $.smoothScroll method instead.
  • The plugin's $.fn.smoothScroll and $.smoothScroll methods use the $.fn.firstScrollable DOM traversal method (also defined by this plugin) to determine which element is scrollable. If no elements are scrollable, these methods return a jQuery object containing an empty array, just like all of jQuery's other DOM traversal methods. Any further chained methods, therefore, will be called against no elements (which, in most cases, means that nothing will happen).

  • For code changes, please work on the "source" file: src/jquery.smooth-scroll.js.
  • Style conventions are noted in the jshint grunt file options and the .jscsrc file. To be sure your additions comply, run grunt lint from the command line.
  • If possible, please use Tim Pope's git commit message style. Multiple commits in a pull request will be squashed into a single commit. I may adjust the message for clarity, style, or grammar.
