您可以使用会话/cookies 来存储检查的值.我不太确定如何让 cookie 工作，所以我会告诉你如何通过会话来做到这一点.特别是 yii 创建的用户会话.

You could use sessions/cookies to store the checked values. I'm not very sure how to make cookies work, so i'll tell you how to do it with sessions. Specifically the user session that yii creates.

现在要使用会话，我们需要将已检查(和未检查)的 id 传递给控制器​​，因此我们将在每次 ajax 更新时(即在分页之间)修改发送到控制器的数据，为此我们利用beforeAjaxUpdate 选项 CGridView.

Now to use sessions we need to pass the checked (and unchecked) ids to the controller, therefore we'll modify the data being sent to the controller on every ajax update(i.e between paginations), to do this we exploit the beforeAjaxUpdate option of CGridView.

我也在使用 CCheckBoxColumn 代替代码中的以下内容(当然您可以修改解决方案以满足您自己的需要):

I'm also using CCheckBoxColumn instead of the following in your code(of course you can modify the solution to suit your own needs):

array(
     'name' => 'demo',
     'type'=>'raw',
     'header' => "Select",
     'value' => 'CHtml::checkBox("email[]","",array("class"=>"check","value"=>$data->email_id))',
),

GridView 更改:

<?php $this->widget('zii.widgets.grid.CGridView', array(
    // added id of grid-view for use with $.fn.yiiGridView.getChecked(containerID,columnID)
    'id'=>'first-grid',

    'dataProvider'=>$model->search(),
    'cssFile' => Yii::app()->baseUrl . '/media/js/admin/css/admingridview.css',

    // added this piece of code
    'beforeAjaxUpdate'=>'function(id,options){options.data={checkedIds:$.fn.yiiGridView.getChecked("first-grid","someChecks").toString(),
        uncheckedIds:getUncheckeds()};
        return true;}',

    'ajaxUpdate'=>true,
    'enablePagination' => true,
    'columns' => array(
            array(
                 'name' => 'id',
                 'header' => '#',
                 'value' => '$this->grid->dataProvider->pagination->currentPage * $this->grid->dataProvider->pagination->pageSize + ($row+1)',
            ),
            array(
                 'name' => 'fb_user_id',
                 'header' => 'FaceBook Id',
                 'value' => 'CHtml::encode($data->fb_user_id)',
            ),
            array(
                 'name' => 'first_name',
                 'header' => 'Name',
                 'value' => 'CHtml::encode($data->first_name)',
            ),
            array(
                 'name' => 'email_id',
                 'header' => 'Email',
                 'value' => 'CHtml::encode($data->email_id)',
            ),

            /* replaced the following with CCheckBoxColumn
              array(
                 'name' => 'demo',
                 'type'=>'raw',
                 'header' => "Select",
                 'value' =>'CHtml::checkBox("email[]","",array("class"=>"check","value"=>$data->email_id))',
              ),
            */

            array(
                 'class' => 'CCheckBoxColumn',
                 'selectableRows' => '2',
                 'header'=>'Selected',
                 'id'=>'someChecks', // need this id for use with $.fn.yiiGridView.getChecked(containerID,columnID)
                 'checked'=>'Yii::app()->user->getState($data->email_id)', // we are using the user session variable to store the checked row values, also considering here that email_ids are unique for your app, it would be best to use any field that is unique in the table
            ),
    ),
));
?>

特别注意 beforeAjaxUpdate 和 CCheckBoxColumn 的代码，在 beforeAjaxUpdate 中，我们将 checkedIds 作为所有 ids(在本例中为 email_ids)的 csv 字符串传递被选中并且 uncheckedIds 作为所有未选中 ID 的 csv 字符串，我们通过调用函数 getUncheckeds() 来获取未选中的框，该函数紧随其后.请注意，在我进行测试时，我使用了(我的表的)整数 id 字段作为唯一字段，而不是电子邮件字段.

Pay special attention to the code for beforeAjaxUpdate and CCheckBoxColumn, in beforeAjaxUpdate we are passing checkedIds as a csv string of all the ids(in this case email_ids) that have been checked and uncheckedIds as a csv string of all the unchecked ids, we get the unchecked boxes by calling a function getUncheckeds(), which follows shortly. Please take note here, that when i was testing i had used an integer id field (of my table) as the unique field, and not an email field.

getUncheckeds() 函数可以像这样在 gridview 的视图文件中的任何地方注册:

The getUncheckeds() function can be registered like this anywhere in the view file for gridview:

Yii::app()->clientScript->registerScript('getUnchecked', "
       function getUncheckeds(){
            var unch = [];
            /*corrected typo: $('[name^=someChec]') => $('[name^=someChecks]') */
            $('[name^=someChecks]').not(':checked,[name$=all]').each(function(){unch.push($(this).val());});
            return unch.toString();
       }
       "
);

在上面的函数中注意选择器和each和push函数.

In the above function pay attention to the selectors and each and push function.

完成后，我们需要修改此视图的控制器/操作.

With that done, we need to modify the controller/action for this view.

public function actionShowGrid(){
     // some code already existing
     // additional code follows
     if(isset($_GET['checkedIds'])){
          $chkArray=explode(",", $_GET['checkedIds']);
          foreach ($chkArray as $arow){
               Yii::app()->user->setState($arow,1);
          }
     }
     if(isset($_GET['uncheckedIds'])){
          $unchkArray=explode(",", $_GET['uncheckedIds']);
          foreach ($unchkArray as $arownon){
               Yii::app()->user->setState($arownon,0);
          }
     }
     // rest of the code namely render()
}

就是这样，它现在应该可以工作了.

That's it, it should work now.
