jquery detach with find

Why does this not work

$rows = $("tbody").detach().find("tr");

but this does?

$rows = $("tbody").find("tr").detach();

I think the second way gets the set of "tr"'s and uses some sort of .each to detach them. I would think it would be more efficient, if there is a way to make it work, to detach the whole body once, and then get the tr's from it...?

$rows in fact does have the same value, however in the first example the tbody tag is missing from the DOM so you need to add it back in.

Note also that

$rows = $("tbody").detach().find("tr"); (around 100ms to detach and store 500 tr elements in an array)

is significantly more efficient than:

$rows = $("tbody").find("tr").detach(); (around 170ms to detach and store 500 tr elements in an array)

First one detatching on $("tbody") and second statement detatching on rows of the table.
