Now with 100% less jQuery.
Emphasis provides dynamic paragraph-specific anchor links and the ability to highlight text in a document, all of which is made available in the URL hash so it can be emailed, bookmarked, or shared.
For more information and examples please go to this blog post:
The main configuration element is specifying what paragraph elements are in scope and are not. To this end we specify the elements on or near Line 54:
this.paraSelctors = document.querySelectorAll('#article p');
This covers a lot of common markup in many sites and blog. However this could be configured for your specific site.
Example: If all your P tags reside in DIV tags with the "entry" classname, then this would be sufficient:
this.paraSelctors = document.querySelectorAll(".entry p");
Over at The New York Times, we'd use the following:
this.paraSelctors = document.querySelectorAll('#story-body > p');
Once up and running, a reader can double tap the SHIFT key to show the Paragraph links. Once in this mode they can toggle links and highlighting on a sentence level
Levenshtein calculation in the script is based on some nice code by Andrew Hedges http://andrew.hedges.name/experiments/levenshtein/
- Further work on UI for highlighting with focus on simplicity
- Support for touch-based devices
