Yii2：使用 Pjax POST 方法在 Gridview 中进行分页搜索

Question

我是 yii2 的初学者，正在尝试在搜索按钮上使用 Pjax 在 Gridview 中搜索字段。我已经使用 GET 方法完成了此操作，但我想通过使用 POST 方法来完成此操作。那我怎么用 Yii2 Pjax(post 方法) 分页呢？

这是我的代码：

_details.php:

<?php          

    use yii\helpers\Html;                             
    use yii\widgets\ActiveForm;         
    use yii\widgets\Pjax;  
    use kartik\depdrop\DepDrop; 


    $js = <<<JS                       
           // get the form id and set the event                         
           $('#bank-details-form').on('beforeSubmit', function(e) {           
           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 txtValue = $("#bankdetails-bank_name").val();   
                    if(txtValue == "")  
                    {  
                        alert("Please select bank name");  
                        return false;  
                    }   

                    var bank_name = $('#bankdetails-bank_name option:selected').text();     
                    var state     = $('#bankdetails-state option:selected').text();     
                    var district  = $('#bankdetails-district option:selected').text();      
                    var city      = $('#bankdetails-city option:selected').text();           
                    var url       = form.attr('action')+ '&BankDetails[bank_name]='+bank_name+'&BankDetails[state]='+state+'&BankDetails[district]='+district+'&BankDetails[city]='+city;         

                    $.pjax.reload({url: url, container:'#bank-grid'});        
                }       
            });                                          
        }).on('submit', function(e){                              
                e.preventDefault();                         
        });

        JS;
        this->registerJs($js); ?>

        <div class="col-lg-5">

Answer 1

尝试使用 Pjax 的 post 方法：

$.pjax.reload({url: url, method: 'POST', container:'#bank-grid'});

Answer 2

这可能对您有所帮助

Pjax::begin(['id' => 'container-id', 'timeout' => false, 'enablePushState' => false, 'clientOptions' => ['method' => 'POST']])
