Question

我搜索所有网络，即谷歌，数据表文档，数据表..但没有找到解决方案。我使用Symfony 4并按照此文https://datatables.net/examples/server_side/simple.html和https://datatables.net/manual/server-side进行操作。然后我的代码就是：

  <html>
<table id="datatable" class="table table-striped table-bordered dataTable no-footer" role="grid" aria-describedby="datatable_info">
                              <thead>
                              <tr class="headings">
                                  <th></th>
                                  <th class="column-title">N&uacute;mero/Ano</th>
                                  <th class="column-title">Cadastrado em</th>
                              </tr>
                              </thead>
                              <tbody>
                              </tbody>
                          </table>
  <script>
  var table = $('#datatable').DataTable( {
                "serverSide": true,
                "info": true,
                "stateSave": true,
                "ajax":{
                    "url":"/decreto/filter",
                    "type": "GET"
                },
                "language": {
                    "url": "//cdn.datatables.net/plug-ins/1.10.16/i18n/Portuguese-Brasil.json"
                },
                "lengthMenu": [ 5, 10, 15, 25 ],
                "columns": [
                    {
                        "className":      'details-control',
                        "orderable":      false,
                        "data":           null,
                        "defaultContent": ''
                    },
                    {
                        "data": "number",
                        "render": function ( data, type, row ) {
                            var z = "";
                            data = data.toString();
                            for (;(4-data.length)>z.length;z = z.concat("0"));

                            return  z+data+"/"+row.year;
                        },
                    },
                    {
                        "data":"registry.date",
                        "render": function ( data ) {
                            var dMy = data.split(" ")[0].split("-");
                            var time = data.split(" ")[1].split(".")[0];

                            return dMy[2]+"/"+dMy[1]+"/"+dMy[0]+" "+time;
                        },
                    },
],
              //*/
              "order": [[1, 'asc']]
            } );
</script>

我的控制器返回：

    $source = $request->query->get("search")["value"];
    $rows = $request->query->get("length");
....
return new JsonResponse(
        array(
            'draw'=>intval(1),
            'recordsTotal'=>intval($em->total()["total"]),
            'recordsFiltered'=>intval(count($list)),
            'data'=>$list,
        )
    );

第一次加载页面时，这个工作正常，只返回我定义的5行。但如果我尝试过滤，就不要工作。对于调试发送的内容，我在Symfony中更改方法，切换GET for Post，并使用URL返回错误：

    jquery.min.js:4 GET http://localhost:8000/decreto/filter?draw=1&columns%5B0%5D%5Bdata%5D=&columns%5B0%5D%5Bname%5D=&columns%5B0%5D%5Bsearchable%5D=true&columns%5B0%5D%5Borderable%5D=false&columns%5B0%5D%5Bsearch%5D%5Bvalue%5D=&columns%5B0%5D%5Bsearch%5D%5Bregex%5D=false&columns%5B1%5D%5Bdata%5D=number&columns%5B1%5D%5Bname%5D=&columns%5B1%5D%5Bsearchable%5D=true&columns%5B1%5D%5Borderable%5D=true&columns%5B1%5D%5Bsearch%5D%5Bvalue%5D=&columns%5B1%5D%5Bsearch%5D%5Bregex%5D=false&columns%5B2%5D%5Bdata%5D=registry.date&columns%5B2%5D%5Bname%5D=&columns%5B2%5D%5Bsearchable%5D=true&columns%5B2%5D%5Borderable%5D=true&columns%5B2%5D%5Bsearch%5D%5Bvalue%5D=&columns%5B2%5D%5Bsearch%5D%5Bregex%5D=false&columns%5B3%5D%5Bdata%5D=files&columns%5B3%5D%5Bname%5D=&columns%5B3%5D%5Bsearchable%5D=true&columns%5B3%5D%5Borderable%5D=true&columns%5B3%5D%5Bsearch%5D%5Bvalue%5D=&columns%5B3%5D%5Bsearch%5D%5Bregex%5D=false&columns%5B4%5D%5Bdata%5D=4&columns%5B4%5D%5Bname%5D=&columns%5B4%5D%5Bsearchable%5D=true&columns%5B4%5D%5Borderable%5D=true&columns%5B4%5D%5Bsearch%5D%5Bvalue%5D=&columns%5B4%5D%5Bsearch%5D%5Bregex%5D=false&order%5B0%5D%5Bcolumn%5D=1&order%5B0%5D%5Bdir%5D=asc&start=0&length=5&search%5Bvalue%5D=el&search%5Bregex%5D=false&_=1520304436769 405 (Method Not Allowed)

然后我修复了过滤发送请求的方法，发送时间：

DecretoController.php on line 194:
array:7 [▼
  "draw" => "1"
  "columns" => array:5 [▶]
  "order" => array:1 [▼
    0 => array:2 [▶]
  ]
  "start" => "0"
  "length" => "5"
  "search" => array:2 [▼
      "value" => "el"
      "regex" => "false"
   ]
  "_" => "1520302968156"
  ]

内容与https://datatables.net/manual/server-side相似。哦，就在那时，继续说上面的网站，我的控制器回来了：

DecretoController.php on line 224:
array:4 [▼
  "draw" => 1
  "recordsTotal" => 6
  "recordsFiltered" => 1
  "data" => array:1 [▼
    0 => array:13 [▶]
  ]
]

数据有1个元素，与i查找匹配。在那之前，好！罚款，完成在这里。将jsonResponse更改为：

{"draw":1,"recordsTotal":6,"recordsFiltered":1,"data":
[{"id":"XYgrQvzrYrYY","number":2,"year":2018,"publish":{"date":"2018-01-11 00:00:00.000000","timezone_type":3,"timezone":"UTC"},"created":{"date":"2018-01-02 00:00:00.000000","timezone_type":3,"timezone":"UTC"},"description":"asfasfasdfasdfsadfsadfsd (admitido pelo sdfasdf), o sr. sfasdfasfas.","registry":{"date":"2018-03-02 02:04:22.000000","timezone_type":3,"timezone":"UTC"},"active":1,"user_id":1,"user_first_name":"Eu,"unidade_id":7,"unidade_name":"Co do Munic\u00edpio","files":[]}]}

出了什么问题？ - 在第一页加载OK - 搜索工作正常 - 按照文档上的顺序返回

我使用https://code.jquery.com/jquery-1.12.4.js

谢谢.. ：（

Answer 1

因为你有固定的绘制值，它应该是每个请求的序列。

的解释：

首先加载。 datatables请求draw = 1。 php return draw = 1。这很好。

如果你做任何动作（排序，搜索，过滤等）。 datatables将请求draw = 2。 php return draw = 1。错误发生了。因为请求绘制与响应绘制不匹配

尝试将'draw'=>intval(1),更改为'draw'=>intval($_GET['draw']),

Datatable jquery服务器端仅适用于加载页面
