How to prevent form element from sending some fields we don't want?

Question

I have a form element that contains about 5 fields which final query is going to create by processing values those fields. So I want to send only final query, not all of tho

Answer 1

Remove the element on submit.

On the onsubmit handler:

$(formElement).submit(function() {
    $(this.field1).remove(); //removing field 1 from query
    return true; //send
});

Disabling the form element also stops it from being entered into the query.(tested on Chrome)

$(formElement).submit(function() {
    this.field1.disabled = true;
    return true; //send
});
