magento 1.9:如何在多个下拉列表中使用依赖项？

我的代码：

protected function _prepareForm()
{
    $form = new Varien_Data_Form();
    $this->setForm($form);
    $fieldset = $form->addFieldset("tuition_form", array("legend"=>Mage::helper("tuition")->__("Student information")));
    $fieldset->addField("secondary", "multiselect", array(              
        "class" => "required-entry",
        "required" => true,
        "name"=>  "subject[secondary]",
        'values'   => Example_Tuition_Block_Adminhtml_Student_Grid::getValueArray34(),
    ));
     $fieldset->addField("others", "text", array(                   
        "class" => "required-entry",
        "required" => true,
        "name"=>  "subject[others]",
    ));
    $this->setForm($form);
     $this->setChild('form_after',
        // The content of the "form_after" block is a Mage_Adminhtml_Block_Widget_Form_Element_Dependence block typ
        $this->getLayout()->createBlock('adminhtml/widget_form_element_dependence')
            ->addFieldMap('junior', 'junior')
            ->addFieldMap('others', 'others')
       ->addFieldDependence('others', 'junior', 'chinese')
       );
   return parent::_prepareForm();
}

我的多次下拉

这里使用的是 javascript 我可以显示或隐藏不使用依赖项的文本框：

$field = $fieldset->addField("junior", "multiselect", array(
    "class" => "required-entry",
    "required" => true,
    "name" => "subject[junior]",
    'onchange' => 'change(this.value)',
    'values' => Example_Tuition_Block_Adminhtml_Student_Grid::getValueArray35(),
));
$field->setAfterElementHtml("<script>
        function change(selectItem){
            var e = document.getElementById('junior');
            var arr = new Array();
                for (var i = 0; i < e.options.length; i++) {
                    if(e.options[i].selected){
                        var val = e.options[i].value;
                        arr.push(val);
                    }
                }
            console.log(arr);
            var values = arr.indexOf('chinese');
            if (values != -1) { 
                document.getElementById('others').style.display = '';
            } else {
                document.getElementById('others').style.display = 'none';   
            } 
        }
        </script>");
$other = $fieldset->addField("others", "text", array(
    "class" => "required-entry",
    "required" => true,
    "name" => "subject[others]",
));
$other->setAfterElementHtml("<script>
                document.getElementById('others').style.display = 'none';               
            </script>");

使用此功能，我可以在更改多个下拉列表时显示和隐藏文本框。
