YIi 设置 ajax 验证

<?php $form = $this->beginWidget('CActiveForm', array(
'id'=>'user-form',
'enableAjaxValidation'=>true,
'enableClientValidation'=>true,
'focus'=>array($model,'firstName'),
)); ?>

然后在控制器里面

public function actionCreate()
{
$model=new User;
$this->performAjaxValidation($model);
if(isset($_POST['User']))
{
$model->attributes=$_POST['User'];
if($model->save())
$this->redirect('index');
}
$this->render('create',array('model'=>$model));
}

protected function performAjaxValidation($model)
{
if(isset($_POST['ajax']) && $_POST['ajax']==='user-form')
{
echo CActiveForm::validate($model);
Yii::app()->end();
}
}
