Class YAHOO.widget.CalendarGroup

Known Subclasses:
YAHOO.widget.Calendar2up
YAHOO.widget.CalendarGroup is a special container class for YAHOO.widget.Calendar. This class facilitates the ability to have multi-page calendar views that share a single dataset and are dependent on each other. The calendar group instance will refer to each of its elements using a 0-based index. For example, to construct the placeholder for a calendar group widget with id "cal1" and containerId of "cal1Container", the markup would be as follows: <div id="cal1Container_0"></div> <div id="cal1Container_1"></div> The tables for the calendars ("cal1_0" and "cal1_1") will be inserted into those containers.

NOTE: As of 2.4.0, the constructor's ID argument is optional. The CalendarGroup can be constructed by simply providing a container ID string, or a reference to a container DIV HTMLElement (the element needs to exist in the document). E.g.:

var c = new YAHOO.widget.CalendarGroup("calContainer", configOptions); or: var containerDiv = YAHOO.util.Dom.get("calContainer"); var c = new YAHOO.widget.CalendarGroup(containerDiv, configOptions);

If not provided, the ID will be generated from the container DIV ID by adding an "_t" suffix. For example if an ID is not provided, and the container's ID is "calContainer", the CalendarGroup's ID will be set to "calContainer_t".

Constructor

Parameters:
id <String> optional The id of the table element that will represent the CalendarGroup widget. As of 2.4.0, this argument is optional.
