Consider this quickhack:

  var form = document.forms[0];
  var elements = form.elements;
  var data = Object.create(null);

  Array.from(elements).forEach((control) => {
    if (!control.name) return;

    var record = {
      type: control.type,
      value: control.value,
      disabled: control.disabled
    };
    
    if (!(control.name in data))
    {
      data[control.name] = record;
    }
    else
    {
      data[control.name] = [].concat(data[control.name], record);
    }
  });

  console.log(data);

I discovered on this occasion

  [].concat(any, record)

to be a nice way to put values in an Array regardless whether there already 
was one :)
