我想在我的数据表中为我的ajax源数据执行行分组。 这是我的html代码： -
<html>
<head>
<link rel="stylesheet" type="text/css" href="//cdn.datatables.net/1.10.0-beta.2/css/jquery.dataTables.css">
<link rel="stylesheet" type="text/css" href="NewFile.css">
</head>
<body>
<table id="example" class="display" cellspacing="0" width="100%">
<thead>
<tr>
<th>Name</th>
<th>Position</th>
<th>Office</th>
<th>Age</th>
<th>Start date</th>
<th>Salary</th>
</tr>
</thead>
<tfoot>
<tr>
<th>Name</th>
<th>Position</th>
<th>Office</th>
<th>Age</th>
<th>Start date</th>
<th>Salary</th>
</tr>
</tfoot>
</table>

<script type="text/javascript" charset="utf8" src="//cdn.datatables.net/1.10.0-beta.2/js/jquery.dataTables.js"></script>
<script>
$(document).ready(function() {
$('#example').dataTable( {
"ajax": 'arrays.txt'
} );
} );
</script>
<script>
</script>
<script>
$(document).ready(function() {
var table = $('#example').DataTable({
"columnDefs": [
{ "visible": false, "targets": 2 }
],
"order": [[ 2, 'asc' ]],
"displayLength": 25,
"drawCallback": function ( settings ) {
var api = this.api();
var rows = api.rows( {page:'current'} ).nodes();
var last=null;
api.column(2, {page:'current'} ).data().each( function ( group, i ) {
if ( last !== group ) {
$(rows).eq( i ).before(
'<tr class="group"><td colspan="5">'+group+'</td></tr>'
);
last = group;
}
} );
}
} );
// Order by the grouping
$('#example tbody').on( 'click', 'tr.group', function () {
var currentOrder = table.order()[0];
if ( currentOrder[0] === 2 && currentOrder[1] === 'asc' ) {
table.order( [ 2, 'desc' ] ).draw();
}
else {
table.order( [ 2, 'asc' ] ).draw();
}
} );
} );
</script>
</body>
</html>
这是我的ajax arrays.txt文件： -

当我尝试运行时，我收到错误消息 DataTables警告：table id = example-无法重新初始化数据表。有关此错误的详细信息，请参阅http://datatables.net/tn/3 那么错误在哪里？
************* UPDATE *********
现在，如果我使用2个javascript代码，我没有收到错误，数据表会被填充，但行分组不会发生。那我的错误现在在哪里？请帮忙 ！！！！我的代码： -

答案 0 :(得分：0)
＆n; tn/3消息是因为您尝试两次初始化同一个表。尝试使用与其余功能相同的功能执行dataload。像这样：
$(document).ready(function() {
table = $('#example').DataTable({
"ajax": "arrays.txt",
"columnDefs": [
{ "visible": false, "targets": 2 }
],
"order": [[ 2, 'asc' ]],
"displayLength": 25,
"drawCallback": function ( settings ) {
var api = this.api();
var rows = api.rows( {page:'current'} ).nodes();
var last=null;
api.column(2, {page:'current'} ).data().each( function ( group, i ) {
if ( last !== group ) {
$(rows).eq( i ).before(
'<tr class="group"><td colspan="5">'+group+'</td></tr>'
);
last = group;
}
} );
}
} );
// Order by the grouping
$('#example tbody').on( 'click', 'tr.group', function () {
var currentOrder = table.order()[0];
if ( currentOrder[0] === 2 && currentOrder[1] === 'asc' ) {
table.order( [ 2, 'desc' ] ).draw();
}
else {
table.order( [ 2, 'asc' ] ).draw();
}
} );
} );
