问题描述
问:如何通过ajax更新CgridVeiw?
状态:我已经完成了 cookie.但是有一个问题.当页面上传时，日期总是显示在起始日期和截止日期文本框中.并且当重新加载页面时，它不会清除.
这是我的看法

这是控制器
公共函数actionIndex(){$accpaymentrecei=new AccPaymentRecei('search');$accpaymentrecei->unsetAttributes();//清除所有默认值if(isset($_GET['AccPaymentRecei']))$accpaymentrecei->attributes=$_GET['AccPaymentRecei'];$acccategory = AccCategory::model()->findAll();$arr_method = array('Cash'=>'Cash', 'Cheque'=>'Cheque', 'Credit Card'=>'Credit Card', '银行转账'='银行转账');$this->from_to_date($accpaymentrecei);//出口();$this->render('index',array('accpaymentrecei'=>$accpaymentrecei，'acccategory'=>$acccategory,'arr_method'=>$arr_method,));}受保护的函数 from_to_date($model){unset(Yii::app()->request->cookies['from_date']);//第一个未设置日期的 cookieunset(Yii::app()->request->cookies['to_date']);//$model=new XyzModel('search');//你的模型$model->unsetAttributes();//清除所有默认值如果(！空($_POST)){Yii::app()->request->cookies['from_date'] = new CHttpCookie('from_date', $_POST['from_date']);//为 from_date 定义 cookieYii::app()->request->cookies['to_date'] = new CHttpCookie('to_date', $_POST['to_date']);$model->from_date = $_POST['from_date'];$model->to_date = $_POST['to_date'];}别的{Yii::app()->request->cookies['from_date'] = new CHttpCookie('from_date', date("Y/m/d"));Yii::app()->request->cookies['to_date'] = new CHttpCookie('to_date', date("Y/m/d"));}}下面的代码 - 只是示例，解决方案的主要原则.第一原则:我们不需要刷新页面(通过提交)，我们只需要在请求后刷新CGridView.
解决方案有几个部分:
我们需要带有一些参数的表单.在您的情况下 - fromDate 和 toDate.你已经有了这个.但是我们不需要任何提交元素.根本！我们将使用 AJAX.
我们需要一些函数来发起 AJAX 请求.例如，此请求的事件将是参数 *from_date* 或 *to_date* 的更改.此函数也必须在请求后更新 CGridView.
我们需要控制器中的动作来处理 AJAX 请求.
让我们从第 2 部分开始.它可能是这样的:
<块引用>Yii::app()->clientScript->registerScript('scriptId',"var ajaxUpdateTimeout;var ajaxRequest;$('**selector_for_parameters_fields**').change(function(){ajaxRequest = $(this).serialize();clearTimeout(ajaxUpdateTimeout);ajaxUpdateTimeout = setTimeout(function () {$.fn.yiiGridView.update(//这是 CGridView 的 id'acc-payment-recei-grid',{数据:ajaxRequest})},//这是延迟300);});");将此代码置于视图中.备注:
$(this).serialize() - 关键时刻.查找更多信息
selector_for_parameters_fields - 给它们( fromDate 和 toDate )一些独特的选择器
我们使用一些 delay(300 毫秒)来减少来自不必要的 AJAX 请求的负载
现在 - 关于控制器中的操作
<块引用>public function actionIndex($fromDate='', $toDate=''){$criteria = new CDbCriteria();if(!empty($fromDate))$criteria->addSearchCondition('你的关于 fromDate 的搜索条件');if(!empty($toDate))$criteria->addSearchCondition('你的关于 toDate 的搜索条件');$dataProvider=new CActiveDataProvider('YourModel',数组('标准' => $标准，))；$this->render('YourView',array('dataProvider'=>$dataProvider,));}它必须有效，但需要针对具体条件进行一些调整.
Q : How to ajax update the CgridVeiw?
Status : I've done with cookie. but there are a problem. it is when the page upload, the date are always show in from-date and to-date text box. and When reload the page, it doesn't clear out.
This is my view
<?php $form=$this->beginWidget('CActiveForm', array(
'id'=>'page-form',
'enableAjaxValidation'=>true,
)); ?>
<div style="margin-top:30px;">
<b>From :</b>
<?php
$this->widget('zii.widgets.jui.CJuiDatePicker', array(
'name'=>'from_date', // name of post parameter
//'value'=>Yii::app()->request->cookies['from_date']->value, // value comes from cookie after submittion
'options'=>array(
'showAnim'=>'fold',
'dateFormat'=>'yy-mm-dd',
),
'htmlOptions'=>array(
'style'=>'height:20px;'
),
));
?>
<span> </span>
<b>To :</b>
<?php
$this->widget('zii.widgets.jui.CJuiDatePicker', array(
'name'=>'to_date',
//'value'=>Yii::app()->request->cookies['to_date']->value,
'options'=>array(
'showAnim'=>'fold',
'dateFormat'=>'yy-mm-dd',
),
'htmlOptions'=>array(
'style'=>'height:20px;'
),
));
?>
<span> </span>
<?php echo CHtml::submitButton('Go'); ?>
<?php
echo CHtml::ajaxSubmitButton('Search', CHtml::normalizeUrl(array('index')),
array(
'success'=>'js:'
.'function(){'
.'$.fn.yiiGridView.update("acc-payment-recei-grid", {url:"index"});'
.'}',
),
array('id'=>'go', 'name'=>'go'));
?>
<?php $this->endWidget(); ?>
<p style="float:right;">
<a href="<?php echo "create"; ?>" class="btn btn-info">New Payment Receive</a>
</p>
</div>
<style>
.items table tr:last-child td:first-child {
-moz-border-radius-bottomleft:10px;
-webkit-border-bottom-left-radius:10px;
border-bottom-left-radius:10px
}
.items table tr:last-child td:last-child {
-moz-border-radius-bottomright:10px;
-webkit-border-bottom-right-radius:10px;
border-bottom-right-radius:10px
}
</style>
<?php $this->widget('zii.widgets.grid.CGridView', array(
'id'=>'acc-payment-recei-grid',
'dataProvider'=>$accpaymentrecei->search(),
//'filter'=>$accpaymentrecei,
'columns'=>array(
//'id',
array('name' => 'acc_category_id',
'value'=>'(isset($data->acccategories->name)) ? CHtml::encode($data->acccategories->name) :""',
),
array('name' => 'acc_recei_id',
'header'=> 'Account Received',
//'value'=>'(isset($data->method)) ? CHtml::encode($data->method) :""',
),
array(
'name' => 'date',
'value'=>'($data->date= 0) ? "" : date("d M yy",strtotime($data->date))',
),
array('name' => 'method',
'value'=>'(isset($data->method)) ? CHtml::encode($data->method) :""',
),
array('name' => 'description',
//'value'=>'(isset($data->method)) ? CHtml::encode($data->method) :""',
),
/*
'created_date',
'updated_date',
'file_name',
*/
array(
'class'=>'CButtonColumn',
),
),
));
This is controller
public function actionIndex()
{
$accpaymentrecei=new AccPaymentRecei('search');
$accpaymentrecei->unsetAttributes(); // clear any default values
if(isset($_GET['AccPaymentRecei']))
$accpaymentrecei->attributes=$_GET['AccPaymentRecei'];
$acccategory = AccCategory::model()->findAll();
$arr_method = array('Cash'=>'Cash', 'Cheque'=>'Cheque', 'Credit Card'=>'Credit Card', 'Bank Transfer'=>'Bank Transfer');
$this->from_to_date($accpaymentrecei);
//exit();
$this->render('index',array(
'accpaymentrecei'=>$accpaymentrecei,
'acccategory'=>$acccategory,
'arr_method'=>$arr_method,
));
}
protected function from_to_date($model)
{
unset(Yii::app()->request->cookies['from_date']); // first unset cookie for dates
unset(Yii::app()->request->cookies['to_date']);
//$model=new XyzModel('search'); // your model
$model->unsetAttributes(); // clear any default values
if(!empty($_POST))
{
Yii::app()->request->cookies['from_date'] = new CHttpCookie('from_date', $_POST['from_date']); // define cookie for from_date
Yii::app()->request->cookies['to_date'] = new CHttpCookie('to_date', $_POST['to_date']);
$model->from_date = $_POST['from_date'];
$model->to_date = $_POST['to_date'];
}else{
Yii::app()->request->cookies['from_date'] = new CHttpCookie('from_date', date("Y/m/d"));
Yii::app()->request->cookies['to_date'] = new CHttpCookie('to_date', date("Y/m/d"));
}
}
Code below - it's only example, main principles of solution. First principle: we don't need refresh page (by the submit), we need only refresh CGridView after request.
The solution has a few parts:
We need form with some parameters. In your case - fromDate and toDate. You have this one already. But we don't need any submit element. At all! We will use AJAX.
We need some function for initiate AJAX-request. For example, let's event for this request will be change of parameters *from_date* or *to_date*. This function also must update CGridView after request.
We need action in controller for processing AJAX-request.
Let's begin from part 2. It may be some like this:
Yii::app()->clientScript->registerScript('scriptId', "var ajaxUpdateTimeout; var ajaxRequest; $('**selector_for_parameters_fields**').change(function(){ ajaxRequest = $(this).serialize(); clearTimeout(ajaxUpdateTimeout); ajaxUpdateTimeout = setTimeout(function () { $.fn.yiiGridView.update( // this is the id of the CGridView 'acc-payment-recei-grid', {data: ajaxRequest} ) }, // this is the delay 300); });" );
Place this code into view. Notes:
$(this).serialize() - key moment. Look for more info
selector_for_parameters_fields - give them ( fromDate and toDate ) some unique
selector
We use some delay (300 ms) for decreasing loading from unnecessary AJAX-requests
Now - about action in Controller
public function actionIndex($fromDate='', $toDate='') { $criteria = new CDbCriteria(); if(!empty($fromDate)) $criteria->addSearchCondition('your search condition about fromDate'); if(!empty($toDate)) $criteria->addSearchCondition('your search condition about toDate'); $dataProvider=new CActiveDataProvider('YourModel', array('criteria' => $criteria,)); $this->render('YourView',array('dataProvider'=>$dataProvider,)); }
It must works, but requires some tuning for concrete conditions.
