Datatable jquery + ajax + php 取不到表中的数据（服务器端处理）

Question

我正在按照这个例子使用数据表https://datatables.net/examples/data_sources/server_side.html

所以我的桌子是：

<table cellpadding="0" cellspacing="0" border="0" class="display" id="tabellaGlossario">
    <thead>
        <th>
             <td>Voce</td>
             <td>Sinonimi</td>
             <td>Sigla</td>
             <td>Macrosettore</td>
             <td>Microsettore</td>      
             <td>Sinonimi</td>
             <td>Sigla</td>
             <td>Macrosettore</td>
             <td>Microsettore</td>           
        </th>
    </thead>
    <tfoot>
        <th>
             <td>Voce</td>
             <td>Sinonimi</td>
             <td>Sigla</td>
             <td>Macrosettore</td>
             <td>Microsettore</td>      
             <td>Sinonimi</td>
             <td>Sigla</td>
             <td>Macrosettore</td>
             <td>Microsettore</td>           
        </th>
    </tfoot>
</table>

我的js：

oTable = $('#tabellaGlossario').dataTable({
        "bJQueryUI": true,
        "sPaginationType": "full_numbers",
        "sDom": '<""f>t<"F"lp>',
        "processing": true,
        "serverSide": true,
        "ajax": "Modules/Glossario/View/Glossario.Table.View.php?lingua_select=2",
    });

我的 ajax 返回了：

{
  "draw": 1,
  "recordsTotal": 1,
  "recordsFiltered": 1,
  "data": [
    [
      "1",
      "2",
      "1",
      "1",
      "1",
      "Parola italiana",
      "Sinonimo italiano",
      "Sigla ita",
      "Note ita"
    ]
  ]
}

我的问题是我总是得到“表中没有可用数据”作为表结果。但正如您所见，ajax 有一些结果（本例中为 1）。 看来我的代码和官方例子中的一样。

无法理解为什么数据没有显示在表格中（并且我在浏览器控制台中没有错误）。

您使用的是动态加载还是任何类型的路由？ 例如 angularjs ngroute 或一些框架的。

在这种情况下它不能工作（不是你正在做的）。您可以按照this 之类的指南或http://jsfiddle.net/qu4a7j24/3/ 之类的示例进行操作

<div ng-app='testTableApp'>

    <div class="container">
        <div ng-controller="mainTable">
            <form action="" method="POST" class="form-horizontal" role="form">
                <div class="form-group">
                    <legend>Filters</legend>
                </div>
                <div class="form-group">
                    <div class="col-sm-10 col-sm-offset-2">
                        <input type="text" value="0" ng-change='reloadData()' ng-model="start">
                        <input type="text" value="50" ng-change='reloadData()' ng-model="end">

                    </div>
                </div>
            </form>

            <table datatable="" dt-options="dtOptions" dt-columns="dtColumns" class="table table-striped table-bordered"></table>
        </div>
    </div>
</div>

var testTableApp = angular.module( 'testTableApp', ['ngRoute', 'ngResource', 'datatables', 'datatables.tabletools', 'datatables.bootstrap', 'datatables.fixedheader'] );
console.log( testTableApp );
testTableApp.controller("mainTable", 
[ '$scope', 'DTOptionsBuilder', 'DTColumnBuilder',
    function ( $scope, DTOptionsBuilder, DTColumnBuilder){

        $scope.end = 5000;


        $scope.getDataSource = function(obj,prefix){
            var src = $scope.dataSource;

            var str = [];
            for(var p in obj) {
                if (obj.hasOwnProperty(p)) {
                    var k = prefix ? prefix + "[" + p + "]" : p, v = obj[p];
                    str.push(typeof v == "object" ?
                    serialize(v, k) :
                    encodeURIComponent(k) + "=" + encodeURIComponent(v));
                }
            }
            return src + "?" + str.join("&");
        }

        var dsParams = {
            start : $scope.start,
            end : $scope.end
        }

        $scope.dsString = $scope.getDataSource( dsParams );


        $scope.buildTable = function(){
            return DTOptionsBuilder

                    },

                        }
                    },

                        }

                ])
                .withFixedHeader({
                    bottom: true
                })
                .withDOM('<"clear"><"#top.hidden-print"<".row"<".col-md-6"i><".col-md-6"f>><".row"<".col-md-6"l><".col-md-6"p>><"clear">T>rt')
                ;            
        }


        $scope.dtOptions = $scope.buildTable();

        $scope.buildColumns = function(){
            return [
                DTColumnBuilder.newColumn('id').withTitle('ID'),
                DTColumnBuilder.newColumn('firstName').withTitle('First name'),
                DTColumnBuilder.newColumn('lastName').withTitle('Last name'),
                DTColumnBuilder.newColumn('city').withTitle('city'),
                DTColumnBuilder.newColumn('state').withTitle('state'),
                DTColumnBuilder.newColumn('zip').withTitle('zip'),
                DTColumnBuilder.newColumn('country').withTitle('country'),
                DTColumnBuilder.newColumn('phone').withTitle('phone'),
                DTColumnBuilder.newColumn('email').withTitle('email')
            ];
        }

        $scope.dtColumns = $scope.buildColumns();


        $scope.reloadData = reloadData;
        $scope.dtInstance = {};

        function reloadData() {
            var resetPaging = false;
            $scope.dtInstance.reloadData(callback, resetPaging);
        }

        function callback(json) {
            console.log(json);
        }

    }
]);

或者只是动态创建表（.load jquery 很有用）
