Setting up the Calendar

In order to support a popup style Calendar which floats above other content on the page, Calendar provides a few extra configuration properties specifically geared towards popup Calendars. Those properties are:

• close - Indicates whether or not a close icon should be displayed in the Calendar. Defaults to false.
• iframe - Indicates whether or not an IFRAME shim should be placed under the Calendar to avoid the bleed-through of "select" elements in IE6 and below. Defaults to true for IE6 and below, when the Calendar is positioned absolutely or relatively.

In addition, the Calendar provides show and hide methods for displaying the Calendar or hiding it from view. This is achieved by setting the Calendar's outer container to display:none.

In this tutorial, we will create a Calendar and a CalendarGroup which can be displayed by clicking a corresponding button. First, the Calendar and CalendarGroup are instantiated using some of the new properties that were introduced in this tutorial.

YAHOO.example.calendar.cal1 = new YAHOO.widget.CalendarGroup("cal1","cal1Container", { pages:2, title:"Please make a selection:", close:true } ); YAHOO.example.calendar.cal1.render(); // Listener to show the two page Calendar when the button is clicked YAHOO.util.Event.addListener("show2up", "click", YAHOO.example.calendar.cal1.show, YAHOO.example.calendar.cal1, true); YAHOO.example.calendar.cal2 = new YAHOO.widget.Calendar("cal2","cal2Container", { title:"Choose a date:", close:true } ); YAHOO.example.calendar.cal2.render(); // Listener to show the single page Calendar when the button is clicked YAHOO.util.Event.addListener("show1up", "click", YAHOO.example.calendar.cal2.show, YAHOO.example.calendar.cal2, true);

Next, we place the markup for the buttons that will invoke the Calendar and CalendarGroup, along with the container div elements that are required for each.

<button id="show2up" type="button">Show CalendarGroup</button> <div id="cal1Container"></div> <button id="show1up" type="button">Show Calendar</button> <div id="cal2Container"></div>

Using CSS, the calendar containers are positioned absolutely to place them above other content in the document and given a z-index so that the order in which they are stacked is defined explicitly if they're rendered on top of each other (we'll place the CalendarGroup above the single page Calendar).

#cal1Container { display:none; position:absolute; left:10px; top:10px; z-index:2} #cal2Container { display:none; position:absolute; left:10px; top:300px; z-index:1}
