        'id',

        'bank_name',

        'state',

        'district',

        'city',

        'branch',

        'time',

        ['class' => 'yii\grid\ActionColumn'],

    ],

]); ?>

_search.php

<div class="bank-index">


   

   


	div class="bank-search">


<?php Pjax::begin(['id' => 'Pjax_bank_id']); ?>


<?php $form = ActiveForm::begin([

    'action' => ['index'],

    'method' => 'get',

]); ?>


<?= $form->field($model, 'id') ?>


<?= $form->field($model, 'bank_name') ?>


<?= $form->field($model, 'state') ?>


<?= $form->field($model, 'district') ?>


<?= $form->field($model, 'city') ?>


<?= 

 $form->field($model, 'time')->widget(Slider::classname(), [

'pluginOptions'=>[

'min'=>0,

'max'=>20,

'step'=>1

]

]);

?>


<?php // echo $form->field($model, 'branch') ?>


<div class="form-group">

    <?= Html::submitButton(Yii::t('app', 'Search'), ['class' => 'btn btn-primary']) ?>

    <?= Html::resetButton(Yii::t('app', 'Reset'), ['class' => 'btn btn-default']) ?>

</div>


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

<?php registerJs($this->render('searchJs.php')); ?>


	<?php \yii\widgets\Pjax::end(); ?>

</div>

searchJs.php

$('#banksearch-time').on('slideStop', function(){

alert('hello');

       var form = $(this);

        if(form.find('.has-error').length) {

            return false;

        }


        $.ajax({

            url: form.attr('action'),

            type: 'post',

            data: form.serialize(),

            success: function(response) { 

                var csrf = yii.getCsrfToken();

                var bank_name = $('#banksearch-bank_name').val();

                var state = $('#banksearch-state').val();

                var district = $('#banksearch-district').val();

                var city = $('#banksearch-city').val();

                var time = $('#banksearch-time').val();

                var url = 'index'+ '&_csrf='+csrf+'&BankSearch[bank_name]='+bank_name+'&BankSearch[state]='+state+'&BankSearch[district]='+district

                           +'&BankSearch[city]='+city +'&BankSearch[time]='+time;

                $.pjax.reload({url: url, container:'#Pjax_bank_id'});


            }

        });    

    }).on('submit', function(e){

    e.preventDefault();

});

Solved The problem was I have not assigned the id to Pjax in gridview.

<?php yii\widgets\Pjax::begin(['id' => 'gridresult']) ?>

I have assigned Pjax id of _search .php.

I changed From:

 $.pjax.reload({url: url, container:'#gridresult'}); 

TO:

$.pjax.reload({url: url, container:'#gridresult'});
