Hi there,

my previous implementation of the function doing the ajax call is not working in datatables 1.10 to abort the previous ajax call:

[code]// Aborting the previous XHR;

if (settings.jqXHR)
settings.jqXHR.abort();

settings.jqXHR = $.ajax({ ... }[/code]

how can I get the expected behavior back?

best regards - Jens

    I replaced

    [code]settings.jqXHR[/code]

    now with

    [code]settings.nTable.jqXHR[/code]

    That seems to work.

    Good to hear you got it working (although slightly surprised, since the jqXHR isn't attached to the table node, it is still on the settings object).

    mmmh... perhaps you would have a look at my method. With settings.jqXHR the call could not become aborted.

    [code]function (data, callback, settings) {
    //data manipulation here ...
    // ...

    // Aborting the previous XHR;

    if (settings.nTable.jqXHR)
    settings.nTable.jqXHR.abort();

    settings.nTable.jqXHR = $.ajax({
    "url": "/",
    "data": data,
    "success": function (json) {
    $(settings.oInstance).trigger('xhr', settings);
    callback( json );
    },
    "dataType": "json",
    "cache": false,
    "type": "post",
    "error": function (xhr, error, thrown) {
    xCore.systemError("", xhr, error);
    return false;
    }
    });
    }
    [/code]

    That is your fnServerData (optionally it could be called `ajax` in 1.10) function is it?

    Why are you assigning the `jqXHR` object to `nTable` ?

    This is where DataTables does its assignment of `jqXHR` : https://github.com/DataTables/DataTablesSrc/blob/master/js/core/core.ajax.js#L95 . So for fnServerData you would need to assign it yourself. If you are using the new `ajax` option, return the XHR object from your function.

    ahh... I see .. that is exactly what I want to do. This was my ajax function. I thought fnServerdata == ajax but actually it's not.

    okay..thanks. now it works.
