Error "dataTable.order() is not a function"

Error "dataTable.order() is not a function"

Note: I have seen that this question has been asked before, but the solution (one jQuery instead of multiple) doesn't help me sadly. I only include jQuery once, and the datatables.min.js and .min.css files are included after.

Whenever I order my table, it's supposed to log which order the user decided to choose. But, using this code right here:

dataTable = $("#hourTable").dataTable({
    language: {
        url: "frameworks/de_de.json",
        responsive: true
    }
});
$("#hourTable").on("order.dt", function(){
    var order = dataTable.order();
    console.log( 'Ordering on column '+order[0][0]+' ('+order[0][1]+')' );
});

does not work. The event does get triggered whenever I need it, but instead of the order chosen, I get the error dataTable.order() is not a function. I did try to print out the dataTable object, and this returns a big amount of functions, but not the one I'm looking for. Here's an example of what I get:


So, I guess it is working correctly? I'm not able to get the order of the table though. Is there something I'm doing wrong here?

Thanks in advance

    Answer ✓

    $("#hourTable").dataTable

    That returns a jQuery object, rather than a DataTables API instance. You want:

    $("#hourTable").DataTable
    

    See the top FAQ :).

    Thanks @allan for the quick response!

    I tinkered around a bit more and found this solution that works pretty well too:

    $("#hourTable").on("order.dt", function(event, settings, ordArr){
        console.log( 'Ordering on column '+ordArr[0]["col"]+' ('+ordArr[0]["dir"]+')' );
    });

    Yes that will do nicely with the order listener.

    If you were to use the $().DataTable() constructor to get the API instance, then you could also use the on() event listener:

    dataTable.on('order', function (...) {
    
    });
    

    Note that is adds the .dt namespace automatically.
