[jQuery] Getting name of element in $.each, when used on object?

[jQuery] Getting name of element in $.each, when used on object?

<div dir="ltr">Hey Folks,
Probably a rather basic question here, but my attempts at figuring it out have come to no success. 
I'm using $.each to loop through the attributes of an object, and write them out into a string.  The object contains a series of parameters that will be passed through a url (for a geoserver WFS should anyone care).  Is there any way to get the name of the attribute so that it can be used as a string?
Mockup object:
{
   request: "getfeature",
   typename: "massgis:TOWNS",
   propertyname: "TOWN_ID,PARCEL_STATUS",
   cql_filter: "INTERSECT(SHAPE,POINT(-72.22%2041.00)"
}
  
Goal is to generate something like....
&request=getfeature&typename=massGIS:TOWNS&propertyname=....
Unfortunately, I can't seem to get 'request' and 'typename' etc.  Anything obvious I'm missing, or is this truly impossible?
Thanks a lot,
 Josh
