Zend Framework中文手册

和 Zend_Form 一起使用 Dojo的最容易的办法是利用 Zend_Dojo_Form， 直接使用或继承都可以。这个范例继承 Zend_Dojo_Form，并示范了所有 dijit 元素的用法。 它生成了四个子表单，并装饰了表单来使用 TabContainer，把每个子表单显示在它自己的 tab 上。

class My_Form_Test extends Zend_Dojo_Form
{
    /**
     * Options to use with select elements
     */
    protected $_selectOptions = array(
        'red'    => 'Rouge',
        'blue'   => 'Bleu',
        'white'  => 'Blanc',
        'orange' => 'Orange',
        'black'  => 'Noir',
        'green'  => 'Vert',
    );

    /**
     * Form initialization
     * 
     * @return void
     */
    public function init()
    {

             ->addSubForm($sliderForm, 'slidertab');
    }
}

通过使用 Zend_Dojo::enableForm() 静态方法，已存在的表单也可以使用 Dojo。

第一个范例示范装饰已存在的表单实例：

$form = new My_Custom_Form();
Zend_Dojo::enableForm($form);
$form->addElement(
'ComboBox',
'query',
array(
    'label'        => 'Color:',
    'value'        => 'blue',
    'autocomplete' => false,
    'multiOptions' => array(
        'red'    => 'Rouge',
        'blue'   => 'Bleu',
        'white'  => 'Blanc',
        'orange' => 'Orange',
        'black'  => 'Noir',
        'green'  => 'Vert',
    ),
)
);

另外，你可以在表单初始化上做点小文章：

class My_Custom_Form extends Zend_Form
{
    public function init()
    {
        Zend_Dojo::enableForm($this);

        // ...
    }
}

当然，如果你可以那样做 ... 你可以并应该简单地修改类来继承 Zend_Dojo_Form， 它可以随时替换已经 Dojo-enabled 的 Zend_Form ...
