JQGridPlugin

jQuery grid widget for Foswiki

jqGrid is an Ajax-enabled JavaScript control that provides solutions for representing and manipulating tabular data on the web. Since the grid is a client-side solution loading data dynamically through Ajax callbacks, it can be integrated with any server-side technology, including PHP, ASP, Java Servlets, JSP, ColdFusion, and Perl. See also the jqgrid wiki for up-to-date documentation.

Special columns

Normally, the data and the way it is displayed in a GRID is specified by the DataForm definition the GRID expression points to. However, there's a set of additional properties of a topic that can be displayed in a GRID. These are specified in the columns parameter to %GRID and are mapped to the actual property as follows:

Colname Data Displayed
Topic topic name link to topic
Modified, Changed time when the topic has been changed recently standard date format
By, Author author of the last modification link to author's homepage
Image, Photo formfields of that name displayed as html <img> tag where the data is used as src link
When FlexFormPlugin is installed, each cell is rendered using %RENDERFORDISPLAY expression.

When ImagePlugin is installed, each Image/Photo cell is rendered using an %IMAGE expression to render thumbnails.

Examples

Users, demonstrating customised columns:
%STARTSECTION{"UsersExample"}%

%GRID{
  form="UserForm"
  web="%USERSWEB%"
  columns="Topic,FirstName,LastName,Organization,Country,Telephone"
  filterbar="on"
  toolbar="on"
  pager="on"
  rownumbers="on"
  width="auto"
  height="auto"
  FirstName_hidden="on"
  LastName_hidden="on"
  Telephone_format="%JQICON{"telephone"}% {{:value}}"
  Topic_title="Name"
  Topic_formatoptions="web:'%USERSWEB%'"
  Topic_format="<a href='%SCRIPTURLPATH{"view"}%/{{:web}}/{{:value}}'>{{:FirstName}} {{:LastName}}</a>"
}%

%ENDSECTION{"UsersExample"}%

%GRID{ form="UserForm" web="Main" columns="Topic,FirstName,LastName,Organization,Country,Telephone" filterbar="on" toolbar="on" pager="on" rownumbers="on" width="auto" height="auto" FirstName_hidden="on" LastName_hidden="on" Telephone_format="telephone {{:value}}" Topic_title="Name" Topic_formatoptions="web:'Main'" Topic_format="{{:FirstName}} {{:LastName}}" }%

FAQ topics, demonstrating custom query with search connector:
%STARTSECTION{"FAQTopicsExample"}%

%GRID{
 query="form.name='FAQForm' OR form.name='%SYSTEMWEB%.FAQForm'"
 connector="search"
 form="%SYSTEMWEB%.FAQForm"
 web="%SYSTEMWEB%"
 filterbar="on"
 pager="on"
 width="auto"
}%

%ENDSECTION{"FAQTopicsExample"}%

%GRID{ query="form.name='FAQForm' OR form.name='System.FAQForm'" connector="search" form="System.FAQForm" web="System" filterbar="on" pager="on" width="auto" }%

Grid Connectors

JQGridPlugin is shipped with three connectors:
  • search - The default connector that uses native Foswiki search.
  • dbcache - Works with DBCachePlugin.
  • solr - Works with SolrPlugin.

You can also create your own custom grid connectors by adding the class name to the ExternalConnectors configure option. All parameters to %GRID% that end in _connectorparam will be passed along to your grid connector. Custom grid connectors must process the following parameters:
  my $sortColumn = $request->param('sidx') || $columns[0];
  my $sortOrder = $request->param('sord') || 'asc';
  my $rowsPerPage = $request->param('rows') || 10;
  my $curPage = $request->param('page') || 1;

Installation Instructions

You do not need to install anything in the browser to use this extension. The following instructions are for the administrator who installs the extension on the server.

Open configure, and open the "Extensions" section. Use "Find More Extensions" to get a list of available extensions. Select "Install".

If you have any problems, or if the extension isn't available in configure, then you can still install manually from the command-line. See http://foswiki.org/Support/ManuallyInstallingExtensions for more help.
