Actually, according to the HTML 4.01 spec, the "name" attribute on "input"
elements[1] is defined as being of type CDATA[2], which is very permissive
in the kinds of characters it allows. There is a section in the XHTML
1.0spec that talks about restricting the allowed characters in the
"name"
attribute[3], but since it's talking about fragment identifiers, I'm not
sure whether it applies to form field names or not (that would suck if it
did, though).
As for the OP's problem, this has worked beautifully for me:
$("input[name='foo[bar][baz]']") // notice the single quotes around
foo[bar][baz]
