无法对具有服务器端JSON的数据表应用range_date

标签： javascript php jquery json jquery-datatables

我有数据表使用从服务器使用JSON数据的方法，并插入 jquery.dataTables.yadcf.js 来创建过滤器。

我的问题：我无法在此处应用range_date。但其他人工作正常。

有人可以帮我吗？我将非常感激！

提前致谢，Guruh

以下是我的截图：
我在date_created字段中输入日期 date_created

这是来自萤火虫 date_created is null

这是我的代码： 的 HTML 

<div id="dynamic">
<table cellpadding="0" cellspacing="0" border="0"class="display" id="example">
<thead>
<tr>
  <th width="20%">ccode</th>
  <th width="25%">city</th>
  <th width="25%">longitude</th>
  <th width="15%">latitude</th>
  <th width="10%">date_created</th>
  <th width="5%">show</th>
</tr>
</thead>
<tbody>
<tr>
  <td colspan="4">Loading data from server</td>
</tr>
</tbody>
<tfoot>
 <tr>
  <th width="20%">ccode</th>
  <th width="25%">city</th>
  <th width="25%">longitude</th>
  <th width="15%">latitude</th>
  <th width="10%">date_created</th>
  <th width="5%">show</th>
</tr>
</tfoot>
</div>

这是我的 Js 

$(document).ready(function() {
    'use strict';
    var oTable = $('#example').dataTable( {
    "bStateSave": true,
    "bProcessing": true,
    "bServerSide": true,
    "sAjaxSource": "scripts/json.php",
    "aoColumns": [
       { "mData": "ccode" },
       { "mData": "city" , "sClass" : "left"},
       { "mData": "longitude" },
       { "mData": "latitude" },
       { "mData": "date_created" },
       { "mData": "active" }
                ],
     "sServerMethod": "POST",
     "fnServerParams": function ( aoData ) {
        aoData.push( { "name": "ccdode", "value": "my_value" } );
     },

     } ).yadcf([
                {column_number : 0},
                {column_number : 1, text_data_delimiter: ",", filter_type: "auto_complete"},
                {column_number : 2, text_data_delimiter: ",", filter_type: "auto_complete"},
                {column_number : 3, text_data_delimiter: ",", filter_type: "auto_complete"},
                {column_number : 4, filter_type: "range_date"},
                {column_number : 5, data: ["Y", "N"], filter_default_label: "Select Y/N"}
              ]);
 } );

这是JSON：
