/*
|
||||
* This plug-in adds another pagination option called ellipses.
|
||||
* This will render the pagination control similar to the full_numbers option,
|
||||
* except it will add ellipses around the page numbers when applicable.
|
||||
* You can set how many page numbers should be displayed with the iShowPages option.
|
||||
* This plug-in also extends the oClasses object with the following properties:
|
||||
* sPageEllipsis, sPageNumber and sPageNumbers.
|
||||
* Finally, this plug-in extends the oSettings object with the following properties:
|
||||
* _iShowPages, _iCurrentPage, _iTotalPages, _iShowPagesHalf, _iFirstPage and _iLastPage.
|
||||

|
||||
* @name Ellipses
|
||||
* @anchor ellipses

* @author <a href="http://daveden.wordpress.com/">Dave Kennedy</a>

|

* // Optional usage of extended oSettings object
|

* return 'Viewing page ' + oSettings._iCurrentPage + ' of ' + oSettings._iTotalPages;
|

|

* // Optional usage of iShowPages option
