Hi again,
*blush* Those same docs tell us that != is also supported by Sizzle.
Note, though, that:
a[class!=whatever]
...is the same as
a:not([class=whatever])
...which is *not* the same as
a:not(.whatever)
...because of multiple class names. Example: With these links:
<a id='a' href='#'>one</a>
<a id='b' href='#' class='whatever'>two</a>
<a id='c' href='#' class='whatever blarg'>three</a>
<a id='d' href='#' class'blarg'>one</a>
"a:not(.whatever)" gives you a,d, but "a[class!=whatever]" and "a:not
([class=whatever])" give you a,c,d. c is on the list because its
value ("whatever blarg") does not *exactly* match "whatever".
Perhaps that relates to why your 1.2.6 code doesn't quite work in 1.3?
HTH, sorry for missing != support earlier.
