home >> about >> errata As with any project of this size, errors are bound to creep into the final product. This page will be updated frequently to reflect all errors discovered in the first printing of JavaScript: The Complete Reference. Please send any comments or errors to jsreferrata@pint.com. We apologize but we cannot respond to each individual inquiry. Chapter 1 p.9 In the code listing, three lines from the bottom, the first </h1> tag should be <h1> Chapter 3 p.80 The last sentence of this page references Appendix E. It should be Appendix C. Chapter 5 p.148 First line under the section Recursive Functions, "While not always the almost efficient..." The word "almost" should be "most." p.148 Second paragraph under the section Recursive Functions, last sentence, "...and which at point the results are returned..." should read "at which point the results are returned." Chapter 6 p.171 The line that reads: for (varclient in customers) should read: for (var client in customers) Chapter 9 p. 269 ! = should be != in example (remove the space between the ! and =) p. 290 Third line from the bottom, the word nodels should be models Ch 14 p.465 In the example at the bottom of the page, type="button | reset | submit" (ie, "reset" instead of "return") p. 470 In the <textarea> tag the single quotes should be " "s p. 471 In the <textarea> tag the single quotes should be " "s p. 473 The bottom example uses “smart” quotes instead of "straight" quotes p. 474 Example The code is correct as-is, but the choice of names for variables and the HTML id/name attributes is rather confusing. The name/id of the radio button group is "radiogroup1." The name of the argument the function "showradiovalue" accepts is "radiogroup." On page 475 a reference to document.testform.radiogroup1 is passed to showradiovalue(). So a reference to the radio group named "radiogroup1" is placed in the variable "radiogroup." The length property of this object is then accessed correctly as "radiogroup.length." p. 475 There are extra blank lines before and after second to last document.write( ) statement in example p. 478 Formatting problems on page 478 in example (note final <option> cook</option>) p. 482 Formatting problems for arrays values on cities["France"] and cities["New Zealand"] p. 482-483 Example If you have less than 3 entries per Country, the Options are not removed properly. To clear the options array just set its length to zero (or do so in addition to nulling the others out). In other words, replace the removeOptions function body with this one statement: optionMenu.options.length = 0; and it works with any length of items. Note that the problem is that nulling elements out is *not* the same as clearing the array though it is used to trigger memory clean-up; it keeps the same array size but inserts null values. p. 483 In <select> statement with id country there is an unnecessary blank line p. 485 Top example has <input> indented but it isn't in the other example Chapter 16 p. 570 In the example, var timeout should be var timeOut. Chapter 19 p. 676 In the last line above the second code listing, "Request object" should be "Response object." Appendix B p. 903 blur ( ) - insert "NS2, IE3" after the word "since" on the second line p. 913 setExpression (property, expression [,language]) - Add asterisk at end p. 921 Notes, just above b (Document Object), add the word "to" in between 'is added' and 'the single array element.' p. 929 Checkbox (Document Object) form Reference to the form in which the button is contained. type String indicating the type of the field, "button." blur( ) Causes the button to lose focus. click( ) Simulates a click on the button. focus( ) Gives the button focus. In all of these property/method listings, 'button' should read 'checkbox' p.983 Under Methods, toExponential facDigits should be fracDigits p.1036 Under Methods, the first two entries (alert(message) and addEventListener) are not alphabetical. Index p.1059 The first item under 'H' handleEvent() is mis-spelled hanldeEvent |
