Two new global events have been introduced to make it easier to add new metadata template renderers and client-side action handlers.
Metadata template renderer
Custom client renderers are registered with the Document Library using the new “registerRenderer” Bubbling event.
Ensure the client-side assets are loaded onto the page using the DocLibCustom / dependencies configuration section.
Using the example to add a new EXIF metadata renderer to produce the output as follows.
Giving the renderer an id of “exposure” also extends the metadata templates using a custom line config:
<line index="20" id="exposure">{exposure exif.label.exposure}</line>
The JavaScript to register the custom renderer is then simply as follows. Note the event name, the event property names and where the custom renderer id is specified.
YAHOO.Bubbling.fire("registerRenderer",
{
propertyName: "exposure",
renderer: function exif_renderer(record, label)
{
...
return html;
}
});
See EXIF renderer source code for the complete source for this example.
Custom action handler
In a very similar way to metadata renderers, new client-side actions are registered using the registerAction Bubbling event message.
YAHOO.Bubbling.fire("registerAction",
{
actionName: "onActionPreviewWebAsset",
fn: function WCMQS_onActionPreviewWebAsset(record)
{
...
}
});
A full example of this can be found in the modules/wcmquickstart/wcmquickstartsharemodule project within the main SkyVault SVN repository.
