Yii2实现ActiveForm ajax提交

<?php $form = ActiveForm::begin([   'action' => ['save'], //提交地址(*可省略*)   'method'=>'post',  //提交方法(*可省略默认POST*)   'id' => 'form-save', //设置ID属性   'options' => [     'class' => 'form-horizontal', //设置class属性   ],   'enableAjaxValidation' => true,   'validationUrl' => 'validate-view', ]); ?>  <?php echo $form->field($model,'company_name', ['inputOptions' => ['placeholder'=>'请输入商家名称','class' => 'form-control'], 'template'=>'<label for="inputCompanyName" class="col-sm-1 control-label"><span class="text-red">*</span> 商家名称</label><div class="col-md-8">{input}</div><label class="col-sm-3" for="inputError">{error}</label>'])->textInput()?>  <?=Html::submitButton('保存',['class'=>'btn btn-primary']); ?>  <?php ActiveForm::end(); ?> 

public function actionValidateView() {   $model = new model();   $request = /Yii::$app->getRequest();   if ($request->isPost && $model->load($request->post())) {     /Yii::$app->response->format = Response::FORMAT_JSON;     return ActiveForm::validate($model);   } } 

public function actionSave() {   /Yii::$app->response->format = Response::FORMAT_JSON;   $params = Yii::$app->request->post();   $model = $this->findModel($params[id]);    if (Yii::$app->request->isPost && $model->load($params)) {     return ['success' => $model->save()];   }   else{     return ['code'=>'error'];   } } 

$(function(){ $(document).on('beforeSubmit', 'form#form-save', function () {     var form = $(this);     //返回错误的表单信息     if (form.find('.has-error').length)     {       return false;     }     //表单提交     $.ajax({       url  : form.attr('action'),       type  : 'post',       data  : form.serialize(),       success: function (response){         if(response.success){           alert('保存成功');           window.location.reload();         }       },       error : function (){         alert('系统错误');         return false;       }     });     return false;   }); });
