yii实现级联下拉菜单的方法

<"white-space:pre"> </span>'id' => 'task-order-src-id',
 ));
 echo $form->dropDownList($model, 'src_shop_id', array(''=>'全部'), array(
 <span style="white-space:pre"> </span>'id' => 'task-shop-id',
 ))
"htmlcode">

public static function options($hasShop = true) {
 $model = new self();
 if($hasShop) $model->hasShop();
 $models = $model->findAll();
 $array = array(''=>'全部');
 foreach($models as $model) {
 $array[$model->src_id] = $model->src_name;
 }
 return $array;
}




2.然后在模版页面中增加JS代码，实现当第一个下拉菜单变化时给第二个下拉菜单进行内容赋值。


<script type='text/javascript'>
$().ready(function(e) {
 $('#task-order-src-id').change(function(e) {
 refreshShops();
 });
 refreshShops();
 function refreshShops() {
 $.get('<"htmlcode">

public function actionGetShops() {
 $srcId = $_GET['srcId'];
 $array = ThirdpartInterfaceConfig::options($srcId);
 $htmlContent = "<option value=''>全部</options>";
 foreach($array as $k=>$v) {
 $htmlContent .= "<option value='{$k}'>{$v}</option>";
 }
 echo $htmlContent;
}
