protocalendar.js を組み込んでみる。 http://labs.spookies.jp/product/protocalendar

CREATE TABLE IF NOT EXISTS `tasks` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `title` varchar(255) NOT NULL,
  `modified` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
  `created` datetime NOT NULL,
  PRIMARY KEY (`id`)
);

• protocalendar を使うために prototype.js を、非同期処理に jQuery を使っているが、共存には注意。

読み込む順番は prototype ⇒ jQuery、その直後に jQuery.noConflict() の記述が必要。

<?php
echo $html->css('stylesheets/simple');
echo $html->script('prototype');
echo $html->script('protocalendar');
echo $html->script('jquery-1.3.2.min');
echo $html->script('jquery-ui-1.7.3.custom.min');
?>
<script language="JavaScript">
jQuery.noConflict();
jQuery(document).ready(function($){
    $(function() {
        $("#TaskIndexForm").submit(function() {
          $.post('/tasks/ajax_add', {
            title: $("#dateformat_calendar").val()
          }, function(rs) {
            $("#tasks").prepend(rs);
            $("#dateformat_calendar").val('');
          });
        });
    });
});
</script>


<h2>Tasks</h2>
<?php echo $form->create('Task', array('default'=>false)); ?>
  <div class="input text">
