[jQuery] Find a exact location in the dom, then move down from that location to another element


Is there a way in jquery to find your exact location in the dom and
then move down from that location to another element? For example can
I get the value of a input[text].someClass after changing it and write
that change only to the next td.someOtherClass in the dom without
using an id?
