Dynamic HTML: The Definitive Guide, 2nd Edition by Danny Goodman The unconfirmed error reports are from readers. They have not yet been approved or disproved by the author or editor and represent solely the opinion of the reader. Here's a key to the markup: [page-number]: serious technical mistake {page-number}: minor technical mistake : important language/formatting problem (page-number): language change or minor formatting problem ?page-number?: reader question or request for clarification This page was updated May 17, 2005. UNCONFIRMED errors and comments from readers: (46) 2nd paragraph; missing right parenthesis in "(see the border, margin, and padding style attributes in Chapter 11" (72) 2nd paragraph; Paranthetic phrase "(even it is..." should be "(even if it is..." [92-93] last function on 92, first function on 93; getObjectWidth and getObjectHeight refer to elem.clip. The variable elem is set by getRawObject, so it is not a style. Only styles contain the clip property. (111) at the bottom of the page there is a reference to Example 5-1, global flags. The global flag script is in Example 4-1. [389] select lists." The next sentence: "It [the label attribute] overrides the normal text associated with the option element." is correct, which is puzzling, since it conflicts with the previous language ("alternate") and the entire next sentence: "Note that IE 5/Mac incorrectly displays the label attribute value in lieu of the element's text.", which is untrue (IE 5/Mac is the only completely compliant implementation of ). The last sentence is true, but could be altered to highlight the behavior as noncompliant (as with the incorrect IE 5/Mac sentence): "Version 6 browsers provide no practical functionality for this attribute." could be changed to something like: "Note that most browsers (with the exception of IE 5+/Mac) incorrectly ignore the label attribute." Finally, an (old) example would be useful to illustrate: In an optgroup-compliant browser, this list would be rendered with the labels: Netscape Navigator 4.x or higher 3.x 2.x 1.x Microsoft Internet Explorer 4.x or higher 3.x 2.x 1.x Opera 3.x or higher 2.x other In older browsers, the list would be rendered with the option text: Netscape Navigator 4.x or higher Netscape Navigator 3.x Netscape Navigator 2.x Netscape Navigator 1.x Microsoft Internet Explorer 4.x or higher Microsoft Internet Explorer 3.x Microsoft Internet Explorer 2.x Microsoft Internet Explorer 1.x Opera 3.x or higher Opera 2.x other Sadly, due to the current partial implementations that ignore the option labels, this elegant backwards-compatible solution will instead be rendered as the much more verbose: Netscape Navigator Netscape Navigator 4.x or higher Netscape Navigator 3.x Netscape Navigator 2.x Netscape Navigator 1.x Microsoft Internet Explorer Microsoft Internet Explorer 4.x or higher Microsoft Internet Explorer 3.x Microsoft Internet Explorer 2.x Microsoft Internet Explorer 1.x Opera Opera 3.x or higher Opera 2.x other which basically destroys the purpose of the optgroup heirarchy. (As does, IMHO, the currently common single-dimensional rendering, since it offers only visual partitioning, and no navigational partitioning to break up long lists.) It is also worth pointing out that the iCab browser builds this mistake to an even more disappointing level, by displaying *both* the option text *and* the option label. {528} 1st section, 2nd line; First let me say this is the book I have been waiting for for years! It's rapidly becoming my Bible in my work. I'm very happy with it! A small addition: The book says that the setAttribute() method in IE4 through 5.5 uses propertynames instead of attributenames. I experienced that the same behaviour holds for IE6.0 for PC. [605] first paragraph of div section; The claim is made that the client and scroll properties are active in IE for the Macintosh. To the best of my knowledge (after trying countless different pages), the scroll properties (specifically scrollLeft and scrollTop) on IE for Mac 5.x do not correlate to what's actually shown on the screen at all. [1035] specifications for onscroll; onscroll works in Netscape 7 and Mozilla 0.9.6+ {1063} pointer; The entry for cursors states that pointer is available as of IE 4 for windows. In fact it was introduced in IE6 and throws an exception if set through JavaScript in previous versions. (1264) for onresize: 'body' should also possibly be included in the objects list
