Description

$("body").is("div span") is returning true

it should always return false, since a body element is /not/ a span element which is a descendant of a div element.

is() seems to return true if there are any two things separated by space, for instance $(whatever).is(".bigclass .otherclass")

is() doesn't support complex selectors (those including spaces, >, etc).

We might add this for 1.3.

can you at least mention that in the documentation? it only says it supports "expressions", which anyone would logically assume means anything on the "selectors" page of the docs.

From http://docs.jquery.com/Traversing/is.

'''Note:''' Only simple expressions are supported. Complex expressions, such as those containing hierarchy selectors (such as +, ~, and >) will always return 'true'.
