使用ajax更新CGridView无法正常工作

标签： javascript jquery ajax yii cgridview

我有一个使用CGridView的网格，当我尝试更新它时，我收到此错误。尝试解决这个问题的方法很长时间仍然无法使其工作。我不确定我错过了什么。

以下是我用来在点击按钮时强制网格刷新的内容。

$('#sessions .refreshdata').live('click', function(e) {
   e.preventDefault();
   $.fn.yiiGridView.update('sessions-grid');
}
);

错误来了，

TypeError: settings is undefined

$grid.addClass(settings.loadingClass);

我不知道这会触发到哪里。

编辑1，

我尝试设置进程输出为true然后它工作但它在同一页面中与我的UI和其他所需脚本混乱。 

$this->getController()->renderPartial('sessionGrid', $params, false, true);

我开始获得yii的默认gridview及其样式。困惑为什么会发生这种情况。

排序在同一网格中也不起作用。当我点击列名的排序链接时，它会刷新页面并将我带到另一页。所以在这种情况下，Ajax完全不起作用。

编辑2，

以下方式也可以按照ANSWER 1

的建议进行工作 
console.log('came in');
e.preventDefault();
$.fn.yiiGridView({ 'ajaxUpdate':['sessions-grid'] }); 
console.log('came out');

如何强制此网格刷新或更新？

编辑3，

当我使用正常方式时，jquery.yiigridview.js会出现错误。设置未定义 - 第203行.. $ grid.addClass（s​​ettings.loadingClass）; 

return this.each(function () {
var $form,
$grid = $(this),
id = $grid.attr('id'),
settings = gridSettings[id];
$grid.addClass(settings.loadingClass);

编辑4，我在下面复制cgridview代码和操作。

<?php TK::registerCssFile('grid');?>
<div id="sessions">

            'update'=>array(

               'url'=>'Yii::app()->controller->createUrl("/activities/default/sessionDelete", array("id"=>$data->id))',
               'options'=>array('class'=>'delete dialog-link-session'),
            ),
         ),
      ),
      array('type'=>'raw',
         'value'=>'$data->registeredCount',
         'htmlOptions'=>array('style'=>'display:none;'),
         'headerHtmlOptions'=>array('style'=>'display:none;'),
      ),
   ),
));
?>
<?php $this->endContent(); ?>
</div>
<style type="text/css">
.grid-view-body
{
    height: 170px;
}
</style>

和行动...... 

public function run()
   {
      Yii::app()->clientScript->scriptMap['*.js'] = false;
      $activities_id = (TK::get('activities_id') ? TK::get('activities_id') : (TK::post('activities_id') ? TK::post('activities_id') : 0));
      $source = (TK::get('source') ? TK::get('source') : (TK::post('source') ? TK::post('source') : 'iJOB'));

      if ($activities_id === null)
        throw new CHttpException(500, Yii::t('activity', 'The requested activity does not exist.'));

      $model = new ActivitySession('search');
      $model->unsetAttributes();
      $model->activities_id = $activities_id;
      $model->closed = null;     

      if (isset($_GET['ActivitySession']))
         $model->attributes = $_GET['ActivitySession'];

      $params = array('model'=>$model, 'source'=>$source);

      if (Yii::app()->request->isAjaxRequest)
         $this->getController()->renderPartial('sessionGrid', $params, false, true);
      else
         $this->getController()->renderPartial('sessionGrid', $params, false, true);
   }

然后我有如下的gridview和刷新按钮......

enter image description here

在使porcessedOutput = true之后，刷新开始工作，但每次增加一个..所以刷新现在多次发生..下面是它现在发生了3次捕获。 enter image description here

我怎么能多次停止这种令人耳目一新的发生是我的问题。

1 个答案:

答案 0 :(得分：1)

只是一个想法，试试

$('#sessions .refreshdata').live('click', function(e) {
   e.preventDefault();
   $.fn.yiiGridView({ 'ajaxUpdate':['sessions-grid']  });
);

希望这会有所帮助

请你在这里展示cgridview。问题可能在于你如何设置
