Question

当尝试使用PHP中的json_encode将数据从SQL放入DataTables时，表格会继续显示＆＃34; Processing ...＆＃34;

我的控制台日志显示：

未捕获的TypeError：undefined不是函数 highcharts.js：17（匿名函数）highcharts.js：17（匿名 function）highcharts.js：308 XHR完成加载：POST ＆＃34; http://website.com/data.php＆＃34 ;. jquery.js：4未捕获的TypeError：无法读取属性＆＃39;长度＆＃39;未定义的 jquery.dataTables.js：2673_fnAjaxUpdateDraw jquery.dataTables.js：2673（匿名函数） jquery.dataTables.js：2519baseAjax.success jquery.dataTables.js：2443m.Callbacks.j jquery.js：2m.Callbacks.k.fireWith jquery.js：2x jquery.js：4m.ajaxTransport.send.b jquery.js：4XMLHttpRequest.send （async）m.ajaxTransport.send jquery.js：4m.extend.ajax jquery.js：4_fnBuildAjax jquery.dataTables.js：2495_fnAjaxUpdate jquery.dataTables.js：2515_fnDraw jquery.dataTables.js：1982_fnReDraw jquery.dataTables.js：2101_fnInitialise jquery.dataTables.js：3276（匿名函数） jquery.dataTables.js：6510m.extend.each jquery.js：2m.fn.m.each jquery.js：2DataTable jquery.dataTables.js：6041（匿名函数） datatables：176m.Callbacks.j jquery.js：2m.Callbacks.k.fireWith jquery.js：2m.extend.ready jquery.js：2J jquery.js：2

我的index.php是这样的：

<table id="table_id" class="display">
    <thead>
        <tr>
            <th>_RowNumber</th>
            <th>DNumber</th>
            <th>ItemNumber</th>
        </tr>
    </thead>



</table>



<script>
$(document).ready(function() {
    $('#table_id').dataTable( {
        "processing": true,
        "serverSide": true,
        "ajax": {
            "url": "<?php echo url(); ?>/new/data.php",
            "type": "POST"
        },
        "columns": [
            { "data": "_RowNumber" },
            {"data": "DNumber"},
            { "data": "ItemNumber" }
        ]
    } );
} );
</script>

和data.php是这样的：

<?php
$SQL = "SELECT *
FROM   (SELECT Row_number()
                 OVER (
                   ORDER BY _sys_id ) AS _RowNumber,
               *
        FROM   (SELECT PList.deliverynumber AS DNumber,
                       PLine.picklistnumber,
                       PLine.picklistsuffix,
                       itemnumber,
                       fromlocation,
                       expectedquantity,
                       pickedquantity,
                       currentlocation,
                       ordernumber,
                       orderline,
                       PLine.complete,
                       PLine.insertdate,
                       itemdescription,
                       PList.complete       AS StatusCode,
                       PList.complete       AS Description,
                       PList.id             AS _SYS_ID
                FROM   picklist PList
                       JOIN pickline PLine
                         ON PList.picklistsuffix = PLine.picklistsuffix
                            AND PList.picklistnumber = PLine.picklistnumber) AS
               LIST_TABLE
        WHERE  1 = 1) AS tmp_rows
WHERE  1 = 1
       AND _RowNumber BETWEEN 1 AND 10  
        ";


$Query = $pdo->prepare($SQL);
$Query->execute();
$rows = array();
foreach ($pdo->query($SQL) as $row) {

    $rows[] = $row;


}

print json_encode($rows);
?>

导航到data.php时的结果显示如下：

我需要更改数据才能在DataTables表中显示？ https://datatables.net/

Answer 1

如果您还使用后台页面，也许您可以像这样解决此问题：当您返回到分页信息的数据结构时，您可以将返回的sEcho重置为0，如下所示：例如：

dataSource.setsEcho(0);//I try set 0，It's work for me，you can try
dataSource.setAaData(tempList);
dataSource.setiTotalDisplayRecords(totalNum);
dataSource.setiTotalRecords(totalNum);

Answer 2

我发现问题是我必须使用

$rows['aaData'][]

而不仅仅是

$rows[]

在foreach（）声明中

Answer 3

请参阅此链接以获取答案。http://legacy.datatables.net/usage/server-side 只需使用 sAjaxDataProp 配置项来修复它

DataTables坚持处理数据，json_encode SQL - PHP
