我有一个Yii2 gridview。我有一个colum，里面有一个复选框，默认选中。选中/取消选中该复选框值时，我想更改值，例如（减去10）在另一列内，即总列，如下所示。
echo GridView::widget([
'dataProvider' => $model->getInsuredCompanyVehiclesArrayDataProvider(),
'filterModel' => $model->getInsuredCompanyVehiclesArrayDataProvider(),
'columns' => [
[
'label' => "checkbox-1-col",
'format' => 'raw',
'value' => function($data)
{
return Html::checkbox('chk1', true, ["page/update", "id" => $data->id]);
},
],
[
'label'=>'Total',
'format' => 'raw',
'value'=>function ($data) {
return $total;
},
],
],
]);
我在访问当前行单元格/列值时遇到问题。我们将非常感谢您的帮助。

我终于找到了一个解决方案，使用Jquery获取GridView行和列，使用PJax进行ajax更新（适用于Yii2）。以下是工作代码：
echo GridView::widget([
'dataProvider' => $model->getInsuredCompanyVehiclesArrayDataProvider(),
'filterModel' => $model->getInsuredCompanyVehiclesArrayDataProvider(),
'id'=>'gridID', // ID to grid wrapper
//'enableHistory' => true,
//'selectableRows' => 1,
'columns' => [
// generated by schmunk42\giiant\crud\providers\RelationProvider::columnFormat
[
"class" => yii\grid\DataColumn::className(),
"attribute" => "insurance_company_id",
//'name' => "companyName",
'label'=>'Company Name',
"value" => function($data){
if ($rel = $data->getInsuranceCompany()->one()) {
return "<img class=\"media-object\" src=\"" . Yii::$app->view->theme->baseUrl . "/images/efu.jpg\" alt=\"\"> " . $rel->name;
} else {
return '';
}
},
"format" => "raw",
],
[
'label'=>'Rate',
'format' => 'raw',
'value'=>function ($data) {
return $data->rate . '%';
},
],
[
'label'=>'Cover Detail',
'format' => 'raw',
'value'=>function ($data) {
return "<a href='" . $data->cover_detail . "' target='_blank'>Click Here</a>";
},
],
// generated by schmunk42\giiant\crud\providers\RelationProvider::columnFormat
[
"class" => yii\grid\DataColumn::className(),
"attribute" => "models_id",
'label'=>'Model',
"value" => function($model){
if ($rel = $model->getModels()->one()) {
return $rel->name;
} else {
return '';
}
},
"format" => "raw",
],
[
'label' => Vas::findOne(1)->name,
'format' => 'raw',
//'name' => "vas1",
'value' => function($data)
{
return Html::checkbox('vas1', true, [ "id" => "vas1",'value' => Vas::findOne(1)->fee]);
},
],
[
'label' => Vas::findOne(2)->name,
'format' => 'raw',
//'name' => "vas2",
'value' => function($data)
{
return Html::checkbox('vas2', true, [ "id" => "vas2",'value' => Vas::findOne(2)->fee]);
},
],
[
'label'=>'Year',
'format' => 'raw',
'value'=>function ($data) {
return $data->year_manufactured;
},
],
[
'label'=>'Amount',
'format' => 'raw',
'value'=>function ($data) {
return $data->rate * Yii::$app->session->get('motorInsuranceEntry')->sumInsured/100;
},
],
[
'label'=>'Total',
'format' => 'raw',
'value'=>function ($data) {
//'value'=>function ($data, $row,$grid) {
//$amount = $data->rate * Yii::$app->session->get('motorInsuranceEntry')->sumInsured/100;
$amount = Yii::$app->session->get('motorInsuranceEntry')->sumInsured/100;
$total = $amount + Vas::findOne(1)->fee + Vas::findOne(2)->fee;
//print_r( $grid);
//var_dump($model, $key, $index, $column);
return $total;
},
],
[
'label'=>'-',
'format' => 'html',
'value'=>function ($data) {
$amount = Yii::$app->session->get('motorInsuranceEntry')->sumInsured/100;
$total = $amount + Vas::findOne(1)->fee + Vas::findOne(2)->fee;
return "<a href='motor-insurance-confirm?company=" . $data->getInsuranceCompany()->one()->name .

},
