【问题描述】：
我想从数据库中刷新表的内容，所以当用户按下刷新按钮时，我将通过 php 从数据库中检索数据，并将此数据发送到 jquery，jquery 将检索到的数据插入表中，我可以成功检索数据但是无法将其插入数据表 这是从数据库中检索数据的 php 代码；
elseif ($id=='refresh_logs'){
$shortname=$_GET['shortname'];
$data_array = array();
$bul="select radacct.UserName,radacct.AcctStartTime,radacct.AcctStopTime,radacct.AcctOutputOctets,radacct.AcctInputOctets,AcctSessionTime,FramedIPAddress,os.mac,nas.shortname,os_platform,acctupdatetime ,RadAcctId from radacct Left join os on os.username=radacct.UserName and os.AcctSessionid=radacct.AcctSessionId left join nas on radacct.NASIPAddress = nas.nasname where nas.shortname='$shortname' limit 1";
//echo($bul);
$result2 = $con2->query($bul);
while($row = $result2->fetch_assoc()) {
$upload=round($row['AcctOutputOctets']/1024/1024,2);
$download=round($row['AcctInputOctets']/1024/1024,2);
if ($row['AcctSessionTime']<60) {
$sure=$row['AcctSessionTime']." Sec";
}
else {
$gun=floor($row['AcctSessionTime']/86400);
$saat=floor(($row['AcctSessionTime'] - $gun*86400)/3600);
$dakika=floor(($row['AcctSessionTime'] - $gun*86400 - $saat*3600)/60);
$sure="";
if ($dakika>0){
$sure=$dakika." Min";
}
if ($saat>0){
$sure=$saat." Hour ".$sure;
}
if ($gun>0){
$sure=$gun." Day ".$sure;
}
}
$row['upload']=$upload;
$row['download']=$download;
$row['sure']=$sure;
array_push($data_array,$row);
}
$data_array=json_encode($data_array);
echo $format = '{
"data":['.$data_array.']}';
}这是将检索到的数据插入到表中的 jquery 代码
$('.refresh').click(function(e) {
e.preventDefault();
var string ='';
var nas_shortname=$('#nas_shortname').val();
var jsonData = $.ajax({ async: false,
url: "Save.php?id=refresh_logs&shortname="+nas_shortname,
dataType: "json"
}).responseText;
//}
var obj = $.parseJSON(jsonData);
$('#resultt').html('<img src="dist/img/ajax_loader_red_128.gif"/>');
$('#my_logs tbody ').remove();
$.fn.dataTable.ext.errMode = 'throw';
var table = $('#my_logs').DataTable({
"processing": true,
"serverSide": true,
"ajax": obj,
"sScrollY": "300px",
"scrollX":true,
"paging": false,
"bFilter": false,
"bInfo": false,
"searching": false,
"bSort" : false,
"fixedColumns": true
});
$('#resultt').html('OK');
});
});
我在控制台中有这个错误
DataTables 警告：表 id=my_logs - JSON 响应无效。有关此错误的更多信息，请参阅http://datatables.net/tn/1 在 J (VM2914 jquery.dataTables.min.js:74)
这是我从服务器端发送到 jquery 的 json 数据
