"partial" multiple selectors

"partial" multiple selectors

In order to refer to the two inner divs here,

<div id="parent">
  <div class="class1"></div>
  <div class="class2"></div>
</div>

I need to use the following multiple selector syntax:

$("#parent .class1, #parent .class2")

I was wondering if there is a shorter idiom for operations like
the above that doesn't require specifying the entire selector,
something along the lines of:

$("#parent .class1, .class2")

which, if I understand correctly, doesn't mean the same as
the former selector.
