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（）
