        //$("#meeting_hidden_id").val('');
       // $("#meeting_hidden_email").val('');
        var hidden_id = $("#meeting_hidden_id");
        remove_id_from_hidden(hidden_id);  
        hidden_id.val( (hidden_id.val() ? hidden_id.val() + "," : hidden_id.val()) + data[1]);
        var hidden_email = $("#meeting_hidden_email");
        hidden_email.val( (hidden_email.val() ? hidden_email.val() + "," : hidden_email.val()) + data[2]);
        var meeting_email = $("#meeting_to");
        meeting_email.val( (meeting_email.val() ? meeting_email.val() + "," : meeting_email.val()) + data[2]);

    });

});

Как удалить дубликат идентификатора с помощью этого кода?

Answer 1

как насчет этого

$("#cont_name2").result(function(event, data, formatted) {
        //$("#meeting_hidden_id").val('');
       // $("#meeting_hidden_email").val('');
        var hidden_id = $("#meeting_hidden_id");
        remove_id_from_hidden(hidden_id); 

        if (!hidden_id.val() || !data[1] in hidden_id.val().split(",")){

           hidden_id.val( (hidden_id.val() ? hidden_id.val() + "," : hidden_id.val()) + data[1]);
        }
        var hidden_email = $("#meeting_hidden_email");
        hidden_email.val( (hidden_email.val() ? hidden_email.val() + "," : hidden_email.val()) + data[2]);
        var meeting_email = $("#meeting_to");
        meeting_email.val( (meeting_email.val() ? meeting_email.val() + "," : meeting_email.val()) + data[2]);

    });
