如何更改模型以便从ajax将模型中的varibale发送到我的表单？ 我希望这可以发生在连接到我的表单的（公共函数comp_group）模型中。 我希望我的模型返回 $ maxId 到 _form.php
这是我的_form.php
<?php
/* @var $this TextController */
/* @var $model Text */
/* @var $form CActiveForm */
?>
<div class="form">
<?php $form=$this->beginWidget('CActiveForm', array(
'id'=>'text-form',
// Please note: When you enable ajax validation, make sure the corresponding
// controller action is handling ajax validation correctly.
// There is a call to performAjaxValidation() commented in generated controller code.
// See class documentation of CActiveForm for details on this.
'enableAjaxValidation'=>TRUE,
'focus'=>array($model,'group'),
// 'clientOptions'=>array(
// 'validateOnChange'=>true, // the default. validate when input changes
// 'validateOnType'=>'true', // validate with EVERY keystroke, hooray!
// 'validationDelay'=>10, // not related to this post--but cool!
// // default delay is 200 ms
// ),
)); ?>
<p class="note">Fields with <span class="required">*</span> are required.</p>
<?php echo $form->errorSummary($model); ?>
<div class="row">
