在 yii 中更新 cgridview 后，Jquery UI Sortable 无法正常工作

Question

我正在开发基于 AJAX 的请求（无重新加载）运行的项目。 在我们更新 cgridview 之前，Jquery sortable 工作正常，之后它就不能工作了。

另外，如果我多次排序，它就会停止工作。这个页面有很多图片列表。

我有如下代码：|

index.php

//Get image details
foreach($arrContent as $key => $value) {
    ob_start();
        $this->widget('ImageWidget',array('imageModel'=>new Images(),'entityType'=>$key,'entityTypeId'=>$specModel->spec_id,'type'=>'View'));
        $arrContent[$key] = ob_get_contents();
    ob_end_clean();
    ob_start();
        $this->widget('ImageWidget',array('imageModel'=>new Images(),'entityType'=>$key,'entityTypeId'=>$specModel->spec_id,'type'=>'Form'));
        $arrContent[$key] .= ob_get_contents();
    ob_end_clean();
}

ob_start();
    $this->widget('BrochureWidget',array('brochureModel'=>new Brochure(),'entityType'=>"SPEC", 'entityTypeId'=>$specModel->spec_id,'type'=>'Form'));
    $brochureContent .= ob_get_contents();
ob_end_clean();

$this->widget('zii.widgets.jui.CJuiTabs',array(
    'tabs'=>array(
        "Brochure({$countBrochure})"=>array(
            'content'=>$brochureContent,
        ),
        "Elevation Images({$countElevationImages})"=>array(
            'content'=>$arrContent['SPEC_ELEVATION']
        ),
    ),
)

通过以下更改解决上述问题：

ImageViewWidget:
注意：我已经删除了afterAjaxUpdate。

 <?php   
 ..........................  
........................   
$this->widget('zii.widgets.grid.CGridView', array(
        'id'=>"image-grid-$this->entityType-$value",
        'ajaxUrl'=>Yii::app()->createAbsoluteUrl('bdxFeed/images',array('entityType'=>$this->entityType,'entityTypeId'=>$this->entityTypeId)),
        //'rowCssClassExpression'=>'"items[]_{$data->image_id }"',
        'rowHtmlOptionsExpression'=>'array("rel"=>"items[]_{$data->image_id}")',
        'dataProvider'=>$dataProvider,
         //'afterAjaxUpdate' => 'sortGrid',
        'htmlOptions'=> array(
            'style'=>'padding:0px',
        ),
        'columns'=>array(

        ........................
        ........................

在js中：

我在下面进行了更改：

 $.fn.yiiGridView.update(id);
 setTimeout(function() {sortGrid(id, URL)}, 2000);

与

$.fn.yiiGridView.update(gridId,{
                            complete: function(jqXHR, status) {
                                if (status=='success'){
                                    sortGrid(gridId, '{$sortUrl}');
                                }
                            }
                        });

就是这样，通过上述更改即可解决。
