|
|

|
|
*
|
|
* Thanks to Scott Yang <http://scott.yang.id.au/>
|
|
* for the original idea and some code
|
|
*
|
|
* @author Renato Formato <rformato@gmail.com>
|
|
*
|
|
* @version 0.37 (9/1/2009)
|
|
*
|
|
* Options
|
|
* - exact (string, default:"exact")
|
|
* "exact" : find and highlight the exact words.
|
|
* "whole" : find partial matches but highlight whole words
|
|
* "partial": find and highlight partial matches
|
|
*
|
|
* - tag_name (string, default:'span')
|
|
* The tag that is used to wrap the matched words
|
|
*
|
|
* - style_name (string, default:'hilite')
|
|
* The class given to the tag wrapping the matched words.
|
|
*
|
|
* - style_name_suffix (boolean, default:true)
|
|
* If true a different number is added to style_name for every different matched word.
|
|
*
|
|
* - debug_referrer (string, default:null)
|
|
* Set a referrer for debugging purpose.
|
|
*
|
|
* - engines (array of regex, default:null)
|
|
* Add a new search engine regex to highlight searches coming from new search engines.
|
|
* The first element is the regex to match the domain.
|
|
* The second element is the regex to match the query string.
|
|
* Ex: [/^http:\/\/my\.site\.net/i,/search=([^&]+)/i]
|
|
*
|
|
* - highlight (string, default:null)
|
|
* A jQuery selector or object to set the elements enabled for highlight.
|
|
* If null or no elements are found, all the document is enabled for highlight.
|
|
*
|
|
* - nohighlight (string, default:null)
|
|
* A jQuery selector or object to set the elements not enabled for highlight.
|
|
* This option has priority on highlight.
|
|
*
|
|
* - keys (string, default:null)
|
|
* Disable the analisys of the referrer and search for the words given as argument
|
|
*
|
|
* - min_length (number, default:null)
|
|
* Set the minimun length of a key
|
|
*
