Skip Link Focus

Make "skip to content" links more accessible.

Usage

Include skip-link-focus.js above the closing </body> tag and initialize it:

<script src="skip-link-focus.js"></script>
<script>skipLinkFocus.init();</script>

Or if you're using Browserify:

require( 'skip-link-focus' ).init();

init() takes an optional options argument:

• options.selector {String} Specifies a DOM selector where skip links are to be found. This is used to handle an edge case where, if a hash is present in the URL on initial load (or refresh), clicking the skip link wouldn't actually fire a hashchange event, making the skip link unusable. Usage example: init( { selector: '.generic-skip-link-class' } ). Defaults to .skip-link.

Background

Makes "skip to content" links work correctly in IE9, Chrome, and Opera to improve accessibility.

Further improvements were made in the _s WordPress theme by Automattic.

This module is based on the _s implementation with the following enhancements:

• Implemented the UMD pattern for use as an AMD, CommonJS, or stand-alone module.
• Added a skip link click handler to fix cases when a hashchange event isn't fired because the address bar already has the corresponding hash.
• Split the functionality into methods to provide a simple API.
