Yii dropDownList 下拉菜单 联动菜单

<?php
echo CHtml::dropDownList('country_id','', array(1=>'USA',7=>'France',3=>'Japan'),
array(
'ajax' => array(
'type'=>'POST', //request type
'url'=>Yii::app()->createUrl('project/dynamiccities'),
'update'=>'#city_id', //selector to update
'data'=>array(Yii::app()->request->csrfTokenName=>Yii::app()->request->getCsrfToken(),'country_id'=>'js $("#country_id").val()')
//leave out the data key to pass all form values through
)));

//empty since it will be filled by the other dropdown
echo CHtml::dropDownList('city_id','', array());

?>

控制器

public function actionDynamiccities()
{
$data=Parts::model()->findAll('prent_id=:prent_id',
array(':prent_id'=>(int) $_POST['country_id']));

$data=CHtml::listData($data,'id','name');
foreach($data as $value=>$name)
{
echo CHtml::tag('option',
array('value'=>$value),CHtml::encode($name),true);
}
}

二、用CActiveForm来实现

在VIEW中实现：

<?php echo $form->dropDownList($model,'province_id',$provinceList(这个值可以通过render传递到页面),array(
'empty'=>'-请选择-',
'ajax'=>array(
//指定请求地址
'url'=>Yii::app()->createUrl('site/dynamicCity'),
//请求数据
'data'=>array('pid'=>'js:this.value'),
//操作元素
'update'=>'#SosInfo_city_id',（注意这个update的值很容易弄错，它由两部分组成：模型+ID，模型->是指本CActiveForm所承载的model名称）
),
)); ?>
<?php echo $form->dropDownList($model,'city_id',City::model()->getCityList($model->province_id),array('empty'=>'-请选择-')); ?>

-->getCityList这个函数返回array（）
