/**
|
||||
* @summary pfPagination for DataTables
|
||||
* @description A collection of API methods providing functionality to paginate DataTables data. This ensures
|
||||
* DataTables meets the Patternfly design pattern while maintaining accessibility.
|
||||
*
|
||||
* The pagination layout is expected to contain the classes as shown in the example below.
|
||||
*
|
||||
* Example:
|
||||
*
|
||||
* <!-- NOTE: Some configuration may be omitted for clarity -->
|
||||
* <table class="table table-striped table-bordered table-hover" id="table1">
|
||||
* <thead>
|
||||
* <tr>
|
||||
* <th><input type="checkbox" name="selectAll"></th>
|
||||
* <th>Rendering Engine</th>
|
||||
* <th>Browser</th>
|
||||
* </tr>
|
||||
* </thead>
|
||||
* </table>
|
||||
* <form class="content-view-pf-pagination table-view-pf-pagination clearfix" id="pagination1">
|
||||
* <div class="form-group">
|
||||
