It chokes on the =

From the jQuery selectors docs:

If you wish to use any of the meta-characters ( such as !"#$%&'()*+,./:;<=>?@[\]^{`{|}~ ) as a literal part of a name, you must escape the character with two backslashes:
. For example, if you have an element with id="foo.bar", you can use the selector $("#foo
.bar"). The W3C CSS specification contains the complete set of rules regarding valid CSS selectors. Also useful is the blog entry by Mathias Bynens on CSS character escape sequences for identifiers.}

If you escape the = with \\ it works.
