How to catch ajax connection error and stop Datatables from throwing an alert?

edwardc

I use connection to multiple sites that are source for my data. One's may be offline at some point and I just want to catch the error (ajax could not load) and inform the user and move on.
This should be pretty simpler but I can't figure it out.

• I managed to catch the error using documentation from here: event: error
• I [... do something with the error...]
• but then I get: "DataTables warning: table id= myID - Ajax error. For more information about this error, please see http://datatables.net/tn/7"

How can I ask Datatable to do nothing after processing my error function?

Have your error handler return true. That should be all that is needed (although I've got a feeling you are going to tell me not... If so, can you give me a link to the page?).

Woow... you must have some paranormal skills. :-)

I pm you with the link to the page and the JS.
Here is the code to initialize dt:

jQuery(document).ready(function () {
    AppCalendar.init();
    $("#tournament_schedule_table").DataTable({
        "ajax": "include/table_ajax.php",
        columns: [
            {title: "Week"},
            // {... something, something, something }
        ],

        // read the custom filters from saved state and populate the filter inputs
        "lengthMenu": [
            [10, 20, 50, 100, 150, -1],
            [10, 20, 50, 100, 150, "All"] // change per page values here
        ],
        "pageLength": 10, // default record count per page

        "order": [
            [1, "asc"]
        ]// set first column as a default sort by asc,
    })
        .on( 'error.dt', function ( e, settings, techNote, message ) {
        console.log( 'Error: Calendar DataTables: ' + message ); // for test purpose
        return true;
    } );
});

any news?

Sorry - I hadn't fully understood that the issue was still present with the above code.

Could you give me a link to an error showing the issue so I can trace it through please?
