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

[Josh Rosenthal]

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
