jquery.arbitrary-anchor.js

This plugin allows the page to scroll to any arbitrary object on the page based on jQuery/CSS selector.

Usage

Usage is simple. Just drop it into your page's head after jQuery. Then it just works.

Add to your page:

<script type="text/javascript" src="jquery.arbitrary-anchor.js"></script>

Then you can add any valid jQuery/CSS selector after the hash (#) in your page's URL, and it will automatically be scrolled to. If the selector returns more than 1 element, the first element found will be scrolled to. You can also place a pipe (|) with a value in milliseconds after the selector to change the time it takes to scroll to the given element, e.g. #.mydiv|200 would scroll to the first element with a class of mydiv and it would scroll to it in 200ms.

Example URLs

URL	Scrolls To
http://example.com#raptor	element with ID of or anchor with name of raptor, if none, scroll to first <raptor> element (is that even a thing?)
http://example.com#p	element with ID of or anchor with name of p, if none, scroll to first <p> element
http://example.com##yo-man	first element with ID of yo-man
http://example.com#.brah	first element with class of brah
http://example.com#.sup.brah	first element with class of sup and brah
http://example.com#.sup.brah｜100	first element with class of sup and brah, scrolled to in 100ms (default is 750ms)
http://example.com#footer	element with ID of or anchor with name of footer, or first <footer> element
http://example.com#footer｜200	same as above, scrolled to in 200ms

Custom Easing Functions

You can easily change arbitrary anchor's easing function, which defaults to linear. Once you've added the jquery easing plugin to your page, change the easing function by setting the global configuration variable:

AA_CONFIG.easingFunction = 'easeOutBounce';

Other options

Here are the options, with their defaults:

AA_CONFIG = {
  animationLength:  750,
  easingFunction:   'linear',
  scrollOffset:     0
};
