The first paragraph originally stated:

Notice that the first <ul> has an ID of selecting plays

It should now read:

Notice that the first <ul> has an ID of selected plays

Listing 2.2

Line 3 of Listing 2.2 was incorrectly:

$('#selected-plays li:not(.horizontal)').addClass('sub-level');li:not(.horizontal)').addClass('sub-level');

It should now be:

$('#selected-plays li:not(.horizontal)').addClass('sub-level');

Listing 2.5

Lines 5–7 of Listing 2.5 were:

.addClass('henrylink');  });}),

They should now omit the superfluous line:

.addClass('henrylink');}

page 46

The variable declaration incorrectly omitted a space. The corrected code should be:

var myTag

The previous implementation incorrectly used the pseudo-selectors’ functionality. The corrected approach utilizing Sizzle’s functionality should be:

(function($) {  $.expr.setFilters.group = function(elements, argument, not) {    var resultElements = [];    for (var i = 0; i < elements.length; i++) {      var test = i % (argument * 2) < argument;      resultElements.push(elements[i]);    }    return resultElements;  };})(jQuery);
