Paging Plugin

This is a special interaction plugin that allows you to integrate paging into templated content items (i.e. a Content Root Object that uses the template and items properties). In order to use this plugin, a corresponding content service must be implemented that processes the requested items (i.e. by evaluating the offset and limit parameters). The plugin can be used with version 0.1.82 or higher.

Usage

The plugin must be loaded with a content service URL that is able to evaluate the offset and limit parameters. Optionally, the requested limit can be indicated (by default, it is set to 20). Please see following action syntax examples.

• content:request:interaction:{URL}@http://msx.benzac.de/interaction/paging.html
• content:request:interaction:{URL}|{LIMIT}@http://msx.benzac.de/interaction/paging.html

The content service URL should contain the keywords {OFFSET} and {LIMIT}, which are replaced with the corresponding values. Please see following action syntax examples.

• content:request:interaction:http://link.to.content?offset={OFFSET}&limit={LIMIT}@http://msx.benzac.de/interaction/paging.html
• content:request:interaction:http://link.to.content?offset={OFFSET}&limit={LIMIT}|40@http://msx.benzac.de/interaction/paging.html

If you would like to use the plugin as reference to implement your own plugin, please have a look at this implementation script: http://msx.benzac.de/interaction/js/paging.js.

Syntax

Parameter syntax of content service URL for paging plugin

Parameter	Type	Default Value	Mandatory	Description
offset	number	0	Yes	The offset that specifies from which offset the items should start. Note: The initial request from the pagaing plugin will always have the offset 0. If an offset greater than 0 is requested, the content service only needs to return the items property, because the other properties are inherited from the initial request.
limit	number	20	Yes	The limit that specifies how many items should be returned. Note: If the content service returns less or more items then indicated, no additional items will be requested.
