The first paragraph reads:
Notice that the first <ul> has an ID of selecting plays
It should read:
Notice that the first <ul> has an ID of selected plays
Listing 2.2
Line 3 of Listing 2.2 reads:
$('#selected-plays li:not(.horizontal)').addClass('sub-
level');li:not(.horizontal)').addClass('sub-level');
It should read:
$('#selected-plays li:not(.horizontal)').addClass('sub-level');
Listing 2.5
Lines 5–7 of Listing 2.5 read:
.addClass('henrylink');
});
});
Line 6 should be omitted, so the lines will just read:
.addClass('henrylink');
});
page 46
The two code blocks incorrectely omit a space for the variable declaration. They begin:
varmyTag
They should begin:
var myTag

The jQuery interface to the Sizzle selector engine changed in the late stages of the writing of this book, and the pseudo-selectors no longer receive the index of an element as one of their arguments. Instead, 0 is always passed as the variable, which causes our custom selector to break:
(function($) {
$.extend($.expr[':'], {
group: function(element, index, matches, set) {
var num = parseInt(matches[3], 10);
if (isNaN(num)) {
return false;
}
return index % (num * 2) < num;
}
});
})(jQuery);
A replacement function can be written that uses Sizzle’s setFilters capability:
(function($) {
$.expr.setFilters.group = function(elements, argument, not) {
var resultElements = [];
for (var i = 0; i < elements.length; i++) {
var test = i % (argument * 2) < argument;
if ((!not && test) || (not && !test)) {
resultElements.push(elements[i]);
}
}
return resultElements;
};
})(jQuery);
