After initiating a table with server processing, there is no Ajax request

This usually means there is a mismatch between the Datatables config, the data returned and/or the number of th you have defined. At minimum we will need to see your Datatables init code, an example of the JSON response (using the browser's dev tools) and your HTMl table config. However it would be better if you can link to your page or a test case replicating the issue.

Ajax request is not sent accordingly and no response

Here is the code to create a table in Html Page

This is the initiation code

$(document).ready(function()

    {
    $('#clients').DataTable( {
         "order": [[ 0, "desc" ]],
         select: true,
         scrollY: true,
         scrollX:true,
         "sRowSelect": "single",
        "processing": true,
        "bPaginate": true,
        "bSort": true,
        "serverSide": true,
        "autoWidth":true,
        // "ajax": "proc.php"
        "ajax": "server_processingclients011.php"
        //"ajax": "proba9.php"
    } );

    } );
    $('#clients tbody').on('dblclick', 'tr', function () {
        var table =$('#clients').DataTable();
        var data = table.row( this ).data();
        document.location.href="http://localhost/client15.html?id="+data[0];

    } );

EDIT: Updated formatting to place triple ticks (```) on their own lines.

kthorngren

Thanks for trying to format the code. The triple ticks need to be on their own lines.

Looks like the problem is that you have defined your header columns with td instead of th. Try changing to th.

I made the changes you recommended and made the upload.Upload code uyaqiq
See if anything's changed ?Or is the problem something else

izumov

By changing the Declaration of the table in the Html code, I achieved that the request was sent but the answer comes with an error net::ERR_CONNECTION_RESET
What could be the reason .How do I resolve the error?

kthorngren

but the answer comes with an error net::ERR_CONNECTION_RESET

This would be a networking issue where a device (server, firewall, etc) in the network path is reseting the network connection. You will need to find what device is responding with the reset and troubleshoot it to find out why. This is not due to Datatables.

Kevin

izumov

both client and server are on the same computer

kthorngren

Then look at the web server logs to determine why it is reseting the connection. Do you have an HTTP server running?

Kevin

izumov

I have working table with 9 columns but need to to withdraw 24. Gradually increasing the number of columns I noticed. That error starts to appear when the number exceeds 15 columns. BEFORE this error does not occur. What can you tell me to do to still increase the number of columns to 24. Is that possible?

izumov

And I note that the working table is connected to the processor issuing data on all 24 columns and they successfully come and the table displays the first 9-15 columns. BUT as soon as the column becomes 16 occurs indicated by me earlier, the error net :: ERR_CONNECTION_RESET. What could be the problem? Prompt me

tangerine

Kevin already told you:

Then look at the web server logs to determine why it is reseting the connection.

izumov

I am interested in such server selectivity,which depends on the number of initiated columns. Although the answer is always based on 24 columns.And that is triggered when меньше16 columns. the code works without errors. And ASM initiated by only the number of columns is 16 acenet to receive an error and do not receive any response

izumov

Suppose that the cause of the error in the web server for this there are good reasons all aJax requests fail. However, there is a strong objection.When I take and copy an Ajax request from the built-in debugger to the browser, the request is executed correctly, which contradicts the assumption about the cause of the error in the web server

izumov

miracles, and only server-side code is reduced to echo 1. and for a table with 14 columns, the Ajax request receives a response of 1. And for a table with 16 columns gets an error net::ERR_CONNECTION_RESET
how can this be I do not understand

kthorngren

Have you looked at your web server logs? That is an error coming from the server. Its not a Datatables error. If you want help debugging please post a link to your page or a test case replicating the issue.
