5th paragraph |
The line:
"a = new Array(10); // a.length == 10 (empty elements 0-9 defined)"
Should be:
"a = new Array(10); // a.length == 1 (element 0 defined)".
This is what happens using NN 6.0.
This implies that the 6th paragraph on pg 154 is also wrong..ie,
"var a = new Array(10);"

2nd paragraph of section 10.1.4 |
The final sentence of this paragraph in the 3/00 print reads:
And /(ab|cd)+|ef)/ matches either the string "ef", or one
or more repititions of either of the strings "ab" or "cd".
The initial error appears to be (to quote emacs): "mismatched set of
parentheses":
/((ab|cd)+|ef)/
It appears that either way, the code will match correctly, but it's generally
a good idea to group properly by matched sets of parentheses.

3rd paragraph |
The statement must include 'LANGUAGE' --
it is shown as:
<SCRIPT SRC="../../javascript/util.js"><SCRIPT>
This statement does not work.
To make it work it should include 'LANGUAGE' --
<SCRIPT LANGUAGE=JavaScript" SRC="../../javascript/util.js"><SCRIPT>

code |
This code is incorrect
<!--&{navigator.platform =3D=3D "win95"};
<SCRIPT LANGUAGE=3D"Javascript">
... // Javascript code
</ SCRIPT>
- --->
"win 95" should be "win32".
More seriously, if {navigator.platform =3D=3D "win95"} is a = Javascript
function that needs to be inside <SCRIPT LANGUAGE=3D"Javascript">=20. So the
code should be thus:
<SCRIPT LANGUAGE=3D"Javascript">
<!--&{navigator.platform =3D=3D "win95"};
... // Javascript code
- --->
</ SCRIPT>

second paragraph of subsection 14.1.2 |
To alleviate a confusing antecedent situation, I recommend changing
"attributes like onClick and onMouseOver of HTML elements" to "HTML-element
attributes such as onClick and onMouseOver".

2nd paragraph |
"Invoking the submit() method of a Form submits the form, exactly as if the
user had clicked on a Submit button...." disagrees with the Form.onsubmit
description on page 512.
As far as I can tell, the Form.onsubmit description is correct when it says
that the Form.onsubmit() method DOES NOT GET CALLED if form.submit() is called
directly.
This is a potentially significant difference between pressing a Submit button
and calling Form.submit().

last section, defining the error msg |
There are too many lines for viewing in the Netscape Alert box. Eliminate all
but the first defining line of msg. I.e., replace
msg = "______________________________________________________
"
msg += "The form was not submitted because of the following error(s).
";
msg += "Please correct these error(s) and re-submit.
";
msg += "______________________________________________________
"
with the single line:
msg = "Please correct these error(s) and re-submit.
";
Also, there are numeric errors. Min and max are not displayed as scripted.
Replace
if (empty_fields) {
msg += "- The following required field(s) are empty:"
+ empty_fields + "
";
if (errors) msg += "
";
}
msg += errors;
alert(msg);
return false;
}
</SCRIPT>
with the following:
if (empty_fields)
msg += "- The following required field(s) are empty:
"
+ empty_fields + "
";
if (errors) {
msg += "
";
msg += errors;
}
alert(msg);
return false;
}
</SCRIPT>
[example 13.5] per the online except from ch13: example 13.5;
the code parses based on comma separated arguments,
but URLs use ampersand as separator characters.

This is part of the DynEl.js cass listing. When I attempt to run it under
Netscape I get a message that "this layer has no properties" at line 83 of the
program (downloaded from your web site).

The figure on p.363 has a box in the JavaScript column containing
'string' and 'netscape.javascript.JSObject'. This is an error since
script code never has netscape.javascript.JSObject objects (this is a
Java class, after all). This Java class exists only in Java and is used
to wrap JavaScript objects. If such an instance is ever passed back to
JavaScript, then it is unwrapped and the original JavaScript object is
passed to JavaScript instead.
(I suppose this has gone unnoticed since not too many people are
implementing LiveConnect in their browsers -- I'm working on
implementing it for OmniWeb 4.1 for Mac OS X --
http://www.omnigroup.com/)

the book mentions about returning false from an onSubmit to |
stop a form submission. Per the Microsoft Website:
"If the event handler is called by the onsubmit attribute of the form
object, the code must explicitly request the return value using the return
function..."
so instead of just calling
<form ... onSubmit="handler" ... >
you need to call
<form ... onSubmit="return(handler)" ... >
The URL for the above info is

middle of page, second code example |
The code fragment:
value = 1234;
binary_value = n.toString(2);
should probably read:
value = 1234;
binary_value = value.toString(2);
or alternatively:
n = 1234;
binary_value = n.toString(2);
for it to make sense and match up with the previous code example.

last paragraph |
IE 5.0 and Communicator 4.72 behave in the opposite manner. I don't have any
older versions of the browsers. The frameset onunload handler is invoked
before the frames' onunload handlers.
All Javascript documentation I can find describes this the same way you
documented it. Everyone agrees it should work that way, but it doesn't!
