Drawcallback receive parameter external

fael_christofano

Hi,
I have one table and this table need to be redraw after one event in external input of DataTable, for exemple one input radio.
When the user checked one radio option, is called the drawcallback function.
My logica is use the ajax in drawcallback, but I readed(and tried), but that is not possible.
My doubt is: How to send by parameter the input radio value in drawcallback function and to make request in server side?

Hi @fael_christofano ,

It might be better to say what you're trying to do, because as you said, the drawCallback is unlikely to be right place.

If the buttons affect the drawing of the table, or the data that you want from the server, the best bet would be to call ajax.reload() in the click event for the radio button. You could send the value of the radio button, or some other logic based on the selection, to the server in ajax.data. This would force a reload based on the selection.

Hope that helps,

Cheers,

Colin

Hi @fael_christofano ,

As I said, you can use ajax.data for that. Set it in the main ajax declaration in the table initialisation.

I Edited my question, did you see?

$(document).ready( function () {
var table = $('#tabelaVagas').DataTable({
       "processing": true,
         "serverSide": true,    
         "ajax": {
                 url: "carregar-vagas.php",
                 data: {$("input[name='rAtivo']:checked").val()},
                 type: "POST",
                 error: function (){
                     $('#post_list_processing').css('display','none');
                 }
})
});

$("input[name='rAtivo']").on('click', function(){
        event.preventDefault();    
        table.reload();
})

If you look at the examples on the page ajax.data, you'll see they're setting a value that goes into the JSON, you're not doing that.

Your line 7 should be something like:

data: {
   checkValue = $("input[name='rAtivo']:checked").val()
}

You would then access checkValue on the server.

Perfect Colin, but I modified this code, stayed like this

data: function ( d ) {
d.rAtivo = $("input[name='rAtivo']:checked").val();
},
