Emphasis ======== 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: http://open.blogs.nytimes.com/2011/01/11/emphasis-update-and-source/ Configuration ------------- The main configuration element si specifiying what paragraph elements are in scope and are not. To this end we specify the elements on or near Line 54: this.paraSelctors = $$( ".entry p:not(p[class]):not(:empty)", ".post p:not(p[class]):not(:empty)", "article p:not(p[class]):not(:empty)" ); This covers a lot of common markup in many sites and blog. However this could be configured for your specific site. Example: If all you P tags reside in DIV tags with the "entry" classname, then this would be sufficient: this.paraSelctors = $$(".entry p:not(p[class]):not(:empty)"); Over at The New York Times, we use the following: this.paraSelctors = $$('.articleBody p:not(p[class]):not(:empty)', '#articleBody p:not(p[class]):not(:empty)', '#content div.entry-content p:not(p[class]):not(:empty)'); Dependencies ------------ Currently this requires that you use the PrototypeJS library - tested with version 1.6. http://prototypejs.org/download Thanks ------ Levenshtein calculation in the script is based on some nice code by Andrew Hedges http://andrew.hedges.name/experiments/levenshtein/ To-Do ----- - Remove framework dependency (PrototypeJS) - Further work on UI for highlighting with focus on simplicity - Social - Support for touch-based devices
