I've got a javascript object, say oBj, with a number of attributes, `oBj.att1, oBj.att2 ... oBj.attn`.

I can pass this object into jQuery's param function to quickly create URIs.

Is it possible to select `oBj.att1` and `oBj.att2` and pass that to the param function?

Please excuse me, I'm very inexperienced with Javascript.

Update:

Code sample:

```
var oBj = new Object();
            oBj.att1 = 1;
            oBj.att2 = 2;
            oBj.att3 = 3;

```
