Question

I’m generating a http 403 on session timeout for ajax calls. When using jquery Datatables I can use fnServeData to intercept the returning call like this

"fnServerData": function ( sSource, aoData, fnCallback ) {
    $.getJSON( sSource, aoData, function (json) { 
            fnCallback(json);
        });
    }

Which normally just forwards the result onto the datatable – but when I return a 403 i just get the http error in my Firebug console – how / where can i check for the 403 so i can display a dialog?

After a bit more digging – one solution is to add an error handler like this:

"fnServerData": function ( sSource, aoData, fnCallback ) {
    $.getJSON( sSource, aoData, function (json) { 
            fnCallback(json);
        });
    }.error(function(jqXHR, statusText, errorThrown) { 
    console.log(jqXHR.status);//403 etc.
});
