Example: Simple Calendar with Selection

This example demonstrates how to instantiate a simple Calendar, with an initial date setting as of today. The Calendar is preconfigured to show the previous and next month's dates.

Try clicking on the toggle buttons to change the initial settings for showing the previous and next months' dates. You can also select dates in the calendar and see selected date on the right, reported via a selectionChange event, and formatted using DataType utility.

Note: be sure to add the yui3-skin-sam classname to the page's <body> element or to a parent element of the widget in order to apply the default CSS skin. See Understanding Skinning. 

<!-- Add an additional blue button style -->
<style>
.yui3-button {
    margin:10px 0px 10px 0px;
    color: #fff;
    background-color: #3476b7;
}
</style>

<div id="demo" class="yui3-skin-sam yui3-g"> <!-- You need this skin class -->

  <div id="leftcolumn" class="yui3-u">
     <!-- Container for the calendar -->
     <div id="mycalendar"></div>
  </div>
  <div id="rightcolumn" class="yui3-u">
   <div id="links" style="padding-left:20px;">
      <!-- The buttons are created simply by assigning the correct CSS class -->
      <button id="togglePrevMonth" class="yui3-button">Toggle Previous Month's Dates</button><br>
      <button id="toggleNextMonth" class="yui3-button">Toggle Next Month's Dates</button><br>
