<p>Calendar provides several events to which an application can subscribe in order to react easily to changes in the state of the Calendar. The events provided are:</p>
|
|
|
|
<ul class="properties">
|
|
<li><strong>beforeRenderEvent</strong> - Fired prior to the rendering of the Calendar</li>
|
|
<li><strong>renderEvent</strong> - Fired after the Calendar is rendered</li>
|
|
<li><strong>beforeSelectEvent</strong> - Fired before a selection is made</li>
|
|
<li><strong>selectEvent</strong> - Fired after a date selection is made. This event receives one argument -- an array of dates fields in the format: [[yyyy,mm,dd],[yyyy,mm,dd]]</li>
|
|
<li><strong>beforeDeselectEvent</strong> - Fired before a deselection is made</li>
|
|
<li><strong>deselectEvent</strong> - Fired after dates are deselected. This event receives one argument -- an array of dates fields in the format: [[yyyy,mm,dd],[yyyy,mm,dd]]</li>
|
|
<li><strong>changePageEvent</strong> - Fired when the active Calendar page is changed</li>
|
|
<li><strong>clearEvent</strong> - Fired when the Calendar is cleared. Calling <em>clear</em> on a Calendar removes all of its selections and sets the page to the current month and year.</li>
|
|
<li><strong>resetEvent</strong> - Fired when the Calendar is reset. Calling a Calendar's <em>reset</em> method resets the Calendar to its original view and selection state.</li>
|
|
</ul>
|
|
|
|
<p>The events are each defined by YAHOO.util.CustomEvent, and are subscribed to using the <em>subscribe</em> method of CustomEvent. In this example, we will display an alert message each time a date is selected or deselected. The <em>selectEvent</em> and <em>deselectEvent</em> events will fire when selections and deselections are made via user interaction (eg, when a user clicks to select a date) or programatically (eg., if a script on the page executes the <em>select</em> method to select a date).</p>
