How to submit complex form using jQuery AJAX?

Question

I am trying to submit a form using jQuery ajax. It has several text fields, several flags and a drop-down list of several parameters (you can select several parameters).

Someone here told me that I can get the values ​​of all selected checkboxes using

$("input:checkbox[name=type]:checked")

Then I can look at all the values ​​returned by the above code, assign them to the array as follows:

var types=new Array();

    $.each(cboxes, function()
      {
         types[types.length]=$(this).val();
      }
    );

And try submitting the form using the following command:

var someField=$("#someField").val();
var someField2=$("#someField2").val();
var data={field1 : someField, field2=someField2, s_types:types};
$.post("signup.php?type=p",types);

But this does not work, in particular, flags are not transmitted correctly. How can I make it work?
