jQuery tablesorter 2.0 - Pager Widget - Ajax

# tablesorter

## Pager Widget - Ajax

### Flexible client-side table sorting

Back to documentation

NOTE!

- In v2.26.0, a page size of "all" will be passed to the server when set; Note this change may break current server methods on number of pages to return.
- This pager WIDGET can not be applied to the original tablesorter.
- Do not use this widget along with the pager plugin.
- The pager.css file also works with this pager widget.
- This widget is still in development as it has not been throughly tested.
- Extensive documentation has not been included, as all functioning is essentially identical to the pager addon, but here are some important differences:
  - All of the options are now set within the `widgetOptions`.
  - Most option names have only been modified by adding `pager_` as a prefix.
  - Exceptions include moving all applied css class names into a `pager_css` option and all selectors into `pager_selectors`, including the original `container` option.
  - See the Javascript code below for a full example of how to use this widget with ajax.
- The "ID" column has a default filter setting of ">30" and a descending sort, but neither is applied as this demo is not connected a server (just a basic JSON file).
