Datatables(jquery 插件)未使用 AJAX 填充 table,返回有效 JSON

Datatables(jquery plugin) not populating table with AJAX, valid JSON being returned

我正在尝试使用 DataTable jquery 插件填充此 HTML table,使用 AJAX 调用从 php 脚本,

服务器响应:

{
    "newsletters": [{
        "anio": "2016",
        "mes": "1",
        "quincena": "1"
    }, {
        "anio": "2016",
        "mes": "1",
        "quincena": "2"
    }]
}

HTML 文件:

<div id="tabla_newsletters" >
     <table id="newsletter_datatable">
         <thead>
            <tr>
                <th>anio</th>
                <th>mes</th>
                <th>quincena</th>
            </tr>
        </thead>
        <tbody>

        </tbody>

     </table>
</div>


<script>
$(document).ready(function(){   


            var table = $('#newsletter_datatable').DataTable( {
                ajax: {
                    url: '/newsletter/getNewsletters',
                    dataSrc: 'newsletters'
                },
                columns:[
                          { 'newsletters': 'anio' },
                          { 'newsletters': 'mes' },
                          { 'newsletters': 'quincena' }
                    ],    
            } );

    });
</script>

然后是我的 php 服务(在 symfony 1.4 中制作),正如我之前所说,根据 JSON 在线验证器返回正确的 JSON:

 public function executeGetNewsletters(sfWebRequest $request){

    $conn = Doctrine_Manager::getInstance()->getCurrentConnection();

    $qry=$conn->execute("Select anio,mes,quincena from newsletters");

            $newsletters = $qry;

            $dataNews = array();
            $i=0;
                foreach ($newsletters as $news)
                    {

                           $dataNews[$i] = array(
                                "anio" => $news['anio'],
                                "mes" => $news['mes'],
                                "quincena" => $news['quincena'],
                            );
                      ++$i;
                    }

            $output = array(
                "newsletters" => $dataNews,
            );

            $json=$this->renderText(json_encode($output));
            return $json;




  }

Datatable 抛出以下错误:

"DataTables warning: table id=newsletter_datatable - Requested unknown parameter '0' for row 0. For more information about this error, please see http://datatables.net/tn/4"

我看了其他案例,但乍一看它们是不同的案例.....

编辑:我已经解决了....问题出在服务器上的脚本上,索引需要是数字....现在它正在正确填充table

最终代码:

-现在服务器的响应是(显然插件只接受这种格式,从我在其他人的错误中看到的):

{"newsletters":[["2016","1","1"],["2016","1","2"]]}

-HTML文件代码为:

<div id="tabla_newsletters" >
     <table id="newsletter_datatable">
         <thead>
            <tr>
                <th>anio</th>
                <th>mes</th>
                <th>quincena</th>
            </tr>
        </thead>
        <tbody>

        </tbody>

     </table>
</div>


<script>
$(document).ready(function(){   


            var table = $('#newsletter_datatable').DataTable( {
                ajax: {
                    url: '/newsletter/getNewsletters',
                    dataSrc: 'newsletters'
                }
            } );

    });
</script>

和php服务代码是(我只是将关联数组的索引从字段名称更改为数字):

public function executeGetNewsletters(sfWebRequest $request){

    $conn = Doctrine_Manager::getInstance()->getCurrentConnection();

    $qry=$conn->execute("Select anio,mes,quincena from newsletters");

            $newsletters = $qry;

            $dataNews = array();
            $i=0;
                foreach ($newsletters as $news)
                    {

                           $dataNews[$i] = array(
                                "0" => $news['anio'],
                                "1" => $news['mes'],
                                "2" => $news['quincena'],
                            );
                      ++$i;
                    }

            $output = array(
                "newsletters" => $dataNews,
            );

            $json=$this->renderText(json_encode($output));
            return $json;




  }

仅供参考:您只需正确操作即可解决您原来的问题:

columns:[
  { data: 'anio' }, //NOT  { 'newsletters': 'anio' }
  { data: 'mes' },
  { data: 'quincena' }
],  

使用 data 定义每个新闻通讯项目的哪个属性应该进入该列。
