Yii2 pjax.reload不适用于gridview记录更新

问题描述：

我已经为网格视图开发了每页功能的行。有一个下拉式选项，如5,10,25,50,100。更改任何我需要为网格视图显示选定行数的下拉选项。对于我创建具有象我的网格视图Pjax容器：Yii2 pjax.reload不适用于gridview记录更新

<?php 

use yii\helpers\Html; 
use yii\grid\GridView; 
use yii\widgets\Pjax; 

$this->title = 'Test Cards'; 
$this->params['breadcrumbs'][] = $this->title; 
?> 

<div class="row"> 
    <div class="test-card-index"> 
     <?= $this->render('_search', [ 'model' => $searchModel ]) ?> 
    </div> 
</div> 

<?php Pjax::begin(['id' => 'test_grid_pjax', 'enablePushState' => false, 'timeout' => 1000000]); ?> 

<div class="row"> 
<?= GridView::widget([ 
    'dataProvider' => $dataProvider, 
    'class' => 'table table-bordered responsive', 
    'id' => 'test_grid', 
    'summary' => "<div class='summary'><label>Showing {begin} - {end} of {totalCount} items.</label></div> <div class='col-sm-6 pageDropdown'> <label>Records per page</label> ".Html::dropDownList('pageSize', (int) Yii::$app->session->get('pageSize', Yii::$app->params['defaultPageSize']), Yii::$app->params['rowPerPage'], ['id' => 'pageSize', 'class' => 'form-control', 'onchange' => 'return reloadGrid("test_grid_pjax",this.value)']) . "</div>", 
    'layout' => '{summary}{items}<div class="pager">{pager}</div>', 
    'options' => ['class' => 'main-grid grid-view full-table'], 
    'columns' => [ 
     'cc_amount', 
     'cc_number',      
     'cc_type', 
     'cc_status' 
     ], 
    ]); 
?> 
</div> 

<?php Pjax::end(); ?>

_search.php样子：

<?php 
use yii\helpers\Html; 
use yii\widgets\ActiveForm; 
?> 

<div class="test-card-search"> 

    <?php $form = ActiveForm::begin([ 
    'action' => ['index'], 
    'method' => 'get', 
    'options' => ['data-pjax' => true , 'class'=>'search_form form-horizontal' ] 

]); ?> 

<div class="form-group"> 
    <div class="row"> 
     <div class="col-md-6"> 
      <?= Html::activeLabel($model, 'cc_number',['class'=>'control-label col-sm-5']); ?> 
      <div class="col-sm-6"> 
       <?= Html::activeTextInput($model, 'cc_number', ['class'=>'form-control col-sm-5','autofocus'=>true]); ?>         
      </div> 
     </div> 
    </div> 
</div> 

<div class="form-group"> 
    <div class="row"> 
     <div class="col-md-6"> 
      <?= Html::activeLabel($model, 'cc_type',['class'=>'control-label col-sm-5']); ?> 
      <div class="col-sm-6">         
       <?= Html::activeDropDownList($model, 'cc_type',[ "RESTRICTED" => Yii::t('app','RESTRICTED'), "UNRESTRICTED" => Yii::t('app','UNRESTRICTED')],['prompt' => Yii::t('app','All Types'), 'class'=>'form-control col-sm-5']); ?>         
      </div> 
     </div> 
    </div> 
</div> 

<div class="form-group"> 
    <div class="col-md-5"></div> 

    <div class="col-md-3"> 
     <div class="form-group"> 
      <?= Html::submitButton('Search', ['class' => 'btn btn-blue']) ?> 
      &nbsp;&nbsp;&nbsp; 
      <?= Html::resetButton('Reset', ['class' => 'btn btn-primary','id'=>'resetButton','onclick'=>"location.href = '".Yii::$app->urlManager->createUrl('testcard/index')."';"]) ?> 
     </div> 
    </div> 
</div> 

<?php ActiveForm::end(); ?> 

</div>

在控制器的动作看起来像：

public function actionIndex() 
{ 

    if (Yii::$app->request->get('pageSize')) { 
     Yii::$app->session->set('pageSize', (int) Yii::$app->request->get('pageSize')); 
    } 

    // to set the selected page number of the grid 
    if (Yii::$app->request->get('page')) { 
     Yii::$app->session->set('page',(int)Yii::$app->request->get('page')); 
    } else { 
     Yii::$app->session->set('page',1); 
    } 

    $searchModel = new TestCardSearch(); 
    $dataProvider = $searchModel->search(Yii::$app->request->queryParams); 

    return $this->render('index', [ 
     'searchModel' => $searchModel, 
     'dataProvider' => $dataProvider, 
    ]); 
}

功能reloadGrid （）就像：

<script type='text/javascript'> 
function reloadGrid(id, value, url) { 
$.pjax.reload({ 
    container: "#" + id, 
    data: $('#search_form').serialize() + "&pageSize=" + value, 
    url: url, 
    push: false, 
    replace: false, 
    timeout: 1000000 
}); 
} 
</script>

通过任何字段搜索它的重新加载整个页面，并在url中设置搜索参数。另一个问题是，在改变“的pageSize”下拉它工作正常，只是第一次，每隔尝试它显示错误像控制台：

Uncaught TypeError: Cannot read property 'reload' of undefined 
at reloadGrid (index:53) 
at HTMLSelectElement.onchange (index:1)

它是JS冲突的问题？我试过很多解决方法，但是没有得到它的工作。

答

我遇到了类似的问题，pjax没有解析网格过滤器中的所有搜索字段。我的解决方案/解决方法/破解是触发一个网格过滤器字段的更改事件，而不是直接调用pjax重新加载。

 $('.date-range-filter').trigger('change'); // this works 

     /* // this didn't parse all the values from my form 
     $.pjax.reload({ 
      container: "#grid-pjax" 
     }); 
     */

它与gridView收集表单值提交的方式有关。它实际上是建立网格列过滤器一个新的虚拟形式，因为对于gridview的

的头过滤器在你的情况，你也应该查看源代码，并没有实际的形式确定的形式正确id'd

<?php $form = ActiveForm::begin([ 
    'action' => ['index'], 
    'method' => 'get', 
    'id'=> 'myFormId' // <---- try giving the form an id 
    'options' => ['data-pjax' => true , 'class'=>'search_form form-horizontal' ] 

]); ?>

您也可以尝试使用pjax窗体选择器属性- 而不是pjax开始和结束。这将让pjax自动获取该表单中的所有输入字段。

<?php 
Pjax::widget([ 
    'id' => 'search-form', 
    'enablePushState' => false, 
    'enableReplaceState' => false, 
    'formSelector' => '#myFormId', // <-- the form to submit with pjax 
    // 'submitEvent' => 'change', /// whatever you want 
    ]); 
?>
