【中文标题】jquery-3.5.1.js:4055 错误数据表无法读取未定义的属性“aDataSort”【英文标题】:jquery-3.5.1.js:4055 error DataTables Cannot read property 'aDataSort' of undefined 【发布时间】:2020-11-11 02:00:12 【问题描述】:早上好,我在引导模式中使用 Datatables 时遇到了这个小问题,该模式应该显示 SQLServer 查询(只是一个选择),它需要能够打印为 Excel 文件或其他格式,但我收到了控制台中的错误“DataTables Cannot read property 'aDataSort' of undefined” 在该错误前面显示“jquery-3.5.1.js:4055”,所以我认为这应该是问题所在。
由于需要将结果导出为格式,所以找到了这个https://datatables.net/extensions/buttons/examples/initialisation/export.html
我正在阅读不同的网站和这里,看起来问题是如何定义依赖项,但我尝试了不同的方法但它不起作用,所以我不确定可能是什么问题......
这些是我的依赖项:

这是模态框内的表格
<table id="table_to_show"></table>
这是应显示表格的同一文件中的函数。
<script type="text/javascript">
$(document).ready(function()
$('#table_to_show').DataTable(
dom: 'Bfrtip',
buttons: [
'copy', 'csv', 'excel', 'pdf', 'print'
]
);
);
</script>
这是为 SELECT 生成的表本身:
$table="";
if ($result)
$data = sqlsrv_has_rows($result);
if ($data === true)
while ($data = sqlsrv_fetch_array($result, SQLSRV_FETCH_ASSOC))
$table=$table.'<tr>
<td>'.$data['ID'].'</td>
<td>'.$data['NAME'].'</td>
<td>'.$data['LNAME'].'</td>
<td>'.$data['number1'].'</td>
<td>'.$data['number2'].'</td>
<td>'.$data['MOBILE'].'</td>
<td>'.$data['MRETIR'].'</td>
</tr>';
sqlsrv_close($conn);
echo '<table class="table table-stripped">
<thead>
<th>Id</th>
<th>Name</th>
<th>Last Name</th>
<th>Number 1</th>
<th>Number 2</th>
<th>Mobile #</th>
<th>Retired?</th>
</thead>
<tbody>'.$table.'
</tbody>';
这就是我所拥有的...任何人都可以帮助我解决这个问题吗?我已经尝试解决了 2 天,也许 3...
提前致谢
【问题讨论】:
【参考方案1】:尝试将 json_encode 用于您的 php 输出 这是我的一些 mysqlI 示例
$sqlSelect = "SELECT * FROM table";
$result = mysqli_query($conn, $sqlSelect);
$someArray = [];
if (mysqli_num_rows($result) > 0)
while ($row = mysqli_fetch_array($result))
array_push($someArray, [
'ID' => $row['ID'],
'NAME' => $row['NAME'],
'LNAME' => $row['LNAME'],
'ETC' => $row['ETC']
]);
$json = json_encode($someArray);
echo ($json);
然后是 JQuery
$.ajax(
url: 'php_file.php',
type: "GET",
success: function(res)
var obj = JSON.parse(res);
console.log(obj);
$('#table_to_show').DataTable(
dom: 'Bfrtip',
destroy: true,
processing: true,
"data" : obj,
"columnDefs": [
"defaultContent": "-",
"targets": "_all"
],
buttons : [ 'copy', 'csv', 'excel', 'pdf', 'print' ],
"columns": [
"data": "ID" ,
"data": "NAME" ,
"data": "LNAME" ,
"data": "ETC"
]
)
;
,
error: function(xhr)
alert("Error Occured!", "error")
);
HTML
<table id="table_to_show" class="display" style="width:100%">
<thead>
<tr>
<th>ID</th>
<th>NAME</th>
<th>LNAME</th>
<th>ETC</th>
</tr>
</thead>
</table>
