p303: Attribute filters: When selecting elements that have an attribute whose value ends with a specified set of characters use this:
[attribute$='value'] (the $ sign was missed in the first print run).
p328-9: In the
on() method there should be a comma between the type of event and the function
on('click', function(e){ (missing in first print run).
p332: The
.slideUp() method hides the selected elements witha sliding motion, and
.slideDown() shows them (in the first print run these were the wrong way around).
p338: The
.add() method creates a new jQuery object with elements added to the set of matched elements.
p364: The text refers to a function called
updateCounter(), it should say
updateCount().
