Don't mix VB and VB.NET, there is a huge difference between them.

First of all, C#'s syntax is based on the C-syntax, which is more modern
and simply makes more sense.

Second, the C# development environment is more advanced than the VB.NET
development environment, for example for the inline documentation, or
the integration of Rational XDE.

In the past, the only advantage of VB was the ease of developing new
applications, especially building UIs. Nowadays, this ease also exists
in C#. There is thus no real reason to keep on learning VB.NET, except
of course for programmers who know only VB and don't want to do the step
to C#.

differ in their Scope chains, and when you create them inside the same
function body during one call to that function, then the scope chains
will also be identical.

Perhaps theoretically possible, but I find no evidence that either IE6
or Moz 1.3 "join" function objects as described in ECMA 262, and in
practice a new function object is created for every execution of an
inner function definition of the form

I think they do join objects in some cases, but it was not that kind
of indistinguishability I was referring to.

The two distinct functions are indistinguishable *as functions*
(extensionally). There is no way the code in the body of the function
alone can act different - it refers to the same variables and contain
the same code, even though the function objects might not compare
equal with == or ===.

When calling the functions with identical arguments, there are only
two things that differ during execution of the function body: The
value of the "this" keyword (if they are methods of different objects)
and the value of arguments.callee (the function object itself).

To make the functions act differently, you must use one of these.
Either treat them like objects (adding properties to the function
object) or using that they are methods of different objects (attaching
information to the "this"-object).

Joining of functions (which I hadn't read in detail before) is
actually interesting.

Compare
---
var x=[];
for (var i=0;i<2;i++){
function foo(){alert(i);};
x[i]=foo;
}
x[0]==x[1]
---
and
---
var x=[];
for (var i=0;i<2;i++){
var foo = function(){alert(i);};
x[i]=foo;
}
x[0]==x[1]
---
The two does act differently in some browsers (meaning that
var foo = function(){}
and
function foo(){}
are not interchangable in all cases).

In Netscape 4, both give false.
In Mozilla, both give true.
In IE6 and Opera 5+, the first gives true and the second false.

All are legal, since it is at the implementation's discretion whether
to create joined objects or not.

Thank you very much. I think the idea of .cssText is all I need. I
can just save and restore this property for the object. Is there any
pitfalls that I should be aware of?

Is .cssText an W3C standard?

I also have a few questions about your replies

<snip>

QUOTE

function SaveCSS(sElement) {

/* store current css properties */
adminSaveState[sElement] = document.getElementById(sElement);

Here, all you save is a reference to the DOM node.

}

In the previous code, all I am saving is a reference(pointer) to the
object? What would I need to do if I have to save a copy of the
object?

<snip>

QUOTE

I tried this:

function getCSSState(id) {
var srcStyle = document.getElementById(id).style;
var dstStyle = {};
for (var i in srcStyle) {
dstStyle[i]=srcStyle[i];
}
return dstStyle;
}

function setCSSStyle(id,srcStyle) {
var dstStyle = document.getElementById(id).style;
for (var i in dstStyle) {
dstStyle[i]=srcStyle[i]; // sets to undefined if not in srcStyle
}
for (i in srcStyle) {
if (dstStyle[i] === undefined) {
dstStyle[i]=srcStyle[i]; // sets those not in dstStyle, if any.
}
}
}

It works - kindof - in IE and Mozilla, but not in Opera. The properties
are not enumerable.

How would you call these functions? I originally declared a global
associative array to store copies of various objects. From what I see
from your functions, you are creating an associative array for a
single object? This probably ties in with my previous question.

thanks again

I have 3 fields in my web form. Field1, Field2, Field3 all containing
strings of dates. At any point of time, not all fields will contain
data.

What I would like to do is to set a variable which would pick up the
data from the fileds. I would only pick from one field. I would like
to do it in the following sequence -

If Field3 is not empty or "NA" then set variable = field3.value
Else
If field2 is not empty or NA then Set varaible = field2.value
Else
Variable=field1.value

I think the If else Statement will work, but I am trying to look for a
simpler code, nested If Else Statements can be difficult to maintain
and debug should there be a problem.

Maybe

Variable=field1.value
If field2 is not empty or NA then Set varaible = field2.value
If Field3 is not empty or "NA" then set variable = field3.value

It might help if you always spell 'variable' the same way, etc.

As a point on clean degradation; if this is for internet use, where
client-side JavaScript cannot be assumed to be available, if the
disabled attribute is set in the HTML for compo2 then the form would be
rendered unusable in the event of client side JavaScript being
disabled/unavailable.

The problem can simply be avoided by having the disabled property of
compo2 set to true by JavaScript in the onload handler for the page.
Thus, in the absence of client-side JavaScript the form remains usable.
The associated server-side process would then be responsible for
validating the form input and returning to the page for correction if
compo1's value was zero, but that level of server-side validation is
required in any case to cover the possibility that a user might
maliciously submit invalid requests.

Your right, it does in IE and Mozilla. Is it proper to assume that

While the calendar itself works, there is a problem with the Show button

You are embedding the InitCalendar.toString() result directly into
the generated HTML. That means that the "<input type=button ..."
is treated as HTML.

You can change
InitCalendar.toString(),
to
InitCalendar.toString().replace(/</g,'&lt;'),

For more safety, you could also change ">" and "&" into entities,

In IE6,0 under Windows this code sample works well when the script is placed
in the BODY section. And when it is in the HEAD, it doesnt work. I think
that is because the browser does not rendering HTML page in HEAD section

I have a very simple problem, nevertheless it seems nobody had it so far !
After working full 5 days on it without a solution I try the Google Forum

I have 2 HTML Pages.
Page2 is a PopUp from Page1.

I have no problem to acces fields from Page1 in Page2 with:

CellValue = this.opener.document.getElementById("IdDate").value;
alert(CellValue);

unless the Id referenced to a Cell in a Table such as <TD
ID=Cell1>Hello</TD
In this case

CellValue = this.opener.document.getElementById("Cell1").value;
alert(CellValue);

Returns the Value Undefined (in the alert box) and not "Hello".

Is this a bug or am I wrong ?

Well, <td> elements don't have a value. I guess it is easiest to use
document.getElementById('Cell1').innerHTML
to access what you regard as the "value" of the cell. In some cases this
might not work as intended, if the cell has child elements then you have
to use
innerText
with IE and Opera and you could create a range and use to string with
Mozilla.

I have a script that creates an IMG tag, myIMG. I have a function f (x).

my handler, I'd use myIMG.onclick=f. I know I could create myHandler h()

You probably never need to use eval.

box = document.forms["checkboxform"].elements["C"+j];

is much more efficient.

QUOTE

var a;
if (box.checked == true) a++;

if (box.checked) a++;

is equivalent and shorter.

You might want to move this line outside the for loop.

Joining of functions (which I hadn't read in detail
before) is actually interesting.

Compare
---
var x=[];
for (var i=0;i<2;i++){
function foo(){alert(i);};
x[i]=foo;
}
x[0]==x[1]
---
and
---
var x=[];
for (var i=0;i<2;i++){
var foo = function(){alert(i);};
x[i]=foo;
}
x[0]==x[1]
---
The two does act differently in some browsers
(meaning that
var foo = function(){}
and
function foo(){}
are not interchangable in all cases).

In Netscape 4, both give false.
In Mozilla, both give true.
In IE6 and Opera 5+, the first gives true and the second false.

I was interested in your results from these tests but I was unable to
reproduce them, particularly your results for Gecko browsers. The
following are my test functions and results:-

function funcTest1(){
var x=[];
for (var i=0;i<2;i++){
function foo(){alert(i);};
x[i] = foo;
}
return (x[0]==x[1]);
}

An inner function declaration within the - for - loop.
Mozilla 1.0, 1.2, 1.3, Netscape 7.02 and K-Meleon 0.7 (Gecko browsers)
== false
Opera 6.05 & 7.11and IE 6 == true
Netscape 4.79 == false

function funcTest3(){
var x=[];
for (var i=0;i<2;i++){
x[i] = function(){alert(i);};
}
return (x[0]==x[1]);
}

An inner function expression within the - for - loop. I would not
expect this to be considered to be the same function on each iteration
of the loop.
Mozilla 1.0, 1.2, 1.3, Netscape 7.02 and K-Meleon 0.7 (Gecko browsers)
== false
Opera 6.05 & 7.11and IE 6 == false
Netscape 4.79 == false

function funcTest5(){
var x=[];
function foo(){alert(i);};
for (var i=0;i<2;i++){
x[i] = foo;
}
return (x[0]==x[1]);
}

An inner function declaration outside of the - for - loop. This I was
expecting to always be considered as the same function (ECMA 262 section
10.1.3).
Mozilla 1.0, 1.2, 1.3, Netscape 7.02 and K-Meleon 0.7 (Gecko browsers)
== true
Opera 6.05 & 7.11and IE 6 == true
Netscape 4.79 == true

There seems to be a discrepancy in the interpretation of the first
function. The inner function declaration looks like it might be being
interpreted as a function expression with optional identifier by Net 4
and Gecko browsers, but even then the results do not conform with my
interpretation of ECMA section 10.1.3 and 13.

I did repeat these test replacing - alert(i); - with - alert("m"); - to
see if the inner function's use of a local variable from it's containing
function was influencing the results. However, that set of tests
produced exactly the same results as above.

QUOTE

All are legal, since it is at the implementation's discretion
whether to create joined objects or not.

I also performed an additional test to gauge the extent to which
function objects would be joined or reused. Following the examples in
the footnote to ECMA 262 section 13.2:-

function getFoo(){
function foo(){alert('m');};
return foo;
}
function funcTest9(){
var x=[];
for (var i=0;i<2;i++){
x[i] = getFoo();
}
return (x[0]==x[1]);
}

- all of the browsers used for the previous test returned false from -
funcTest9 -.

As the - foo - function returned from each call to - getFoo - should be
"indistinguishable" from one and other -

<quote cite="ECMA 262 section 13.2">
.. . . the differences between their [[Scope]] properties are not
observable, . . .
</quote>

- I would have to conclude that none of these browsers have chosen to
implement the optional optimisation mentioned in ECMA 262 section 13.2
(and 13.1.2) and that no joining of function objects is going on.

Having apparently ascertained that any inner function returned by a
function will be a unique function object and that function expressions
produce unique function objects I think that this has implications for
how inner functions should be used. For example:-

function MyObject(x){
this.x = x;
this.getX = function(){
return this.x
};
}

- will create a new function object for each MyObject created, while:-

function MyObject(x){
this.x = x;
}
MyObject.prototype.getX = function(){
return this.x
}

- should share the same function object between all instances of
MyObject.

The same would go for assigning an event handler with an inner function
expression. One function object for each invocation of the outer
function. While defining the handler function externally and assigning
it by reference would allow the same function object to be shared by
many event handlers.

If the browsers cannot or will not recognise when two functions are
indistinguishable and optimise their use the onus falls on the script
author to do so. Saving memory consumption and improving execution speed
(as less new function objects need to be created).

Leaving inner functions to be used only when their special
characteristics confer some advantage, when they actually are accessing
properties of their outer functions and/or resulting closures. (Or maybe
in code that will only be executed once.)

what we are seeing from IE and Opera *is* the joining of the
functions.

My reading of section 10.1.3 would suggest that, recognising the
function declaration as such, IE and Opera are adding a named reference
to one unique function object to the variable object and just
disregarding the fact that the declaration appears in a - for - loop, so
there is only one function object and no joining is taking place. (and
the function is not re-declared in each iteration of the loop).

My belief is encouraged by this test:-

function funcTest10(){
while(false){
function foo(){alert(i);};
}
return foo;
}
alert(funcTest10());

Where Opera and IE alert the toString version of foo and Gecko browsers
produce a JavaScript error - foo is undefined - on the - return foo; -
line.

I think it is the Gecko browsers that are off spec here (Netscape 4 can
be excused for historical reasons).

In any event, if Opera and IE were joining the functions in the previous
example why would they not implement the joining in the case that
followed the example specifically targeted for optimisation in ECMA 262
section 13.2?

<snip>

QUOTE

...

Speed an efficiency are personal obsessions. That probably stems form my
learning 68000 assembly language in the early 1990s. When you are
gauging code by the clock-cycle you get a good feeling for what is fast
and what isn't. I haven't been able to shake the impression that if code
can be faster it probably should be. I doubt that I will, it is part of
the "craft".

But JavaScript is inevitably relatively slow. Take the recent thread on
vector graphics; the library that Jim referenced uses a lot of the fast
algorithms that I implemented in assembly language for 3D vector
graphics on 8Mhz CPUs, but on a 100 times faster computer they are still
nowhere near fast enough to do 3D vector animation in a web browsers
(even the relatively crude stuff from the early 90s (though I might yet
see if I can do better)).

Memory doesn't seem that important on a desktop computer, with a 32 bit
Windows system having a 2Gb (or is it 4, I forget) memory map and using
a swap file to fake any that is not physically present. But what about
PDAs? The browser and the DOM representation take up a lot of the
available memory and don't leave that much for JavaScript to work in.

QUOTE

However, I am weary at designing programs for such a diverse
and evolving platform as browsers' Javascript by aiming at
the artifacts of the current impementations. I would much

I don't think that the approach that I was recommending would
necessarily compromise maintenance. Assigning public methods to a
prototype is virtually self-documenting and assigning externally defined
method to event handlers should be clear enough if they are well named
and commented.

| for example, could i simply feed server supplied text or html to a
| textbox or inline frame without reloading the entire page? the text
| or embeded html or whatever would come from a php script, when a user
| clicked a button or an image or something. i realize i'm being hazy,
| but i'm flexible as to the implementation. i've been playing with php
| and i'd like to work on a chat script, but i don't know how to handle
| the client side. i've skimmed through the javascript reference on the
| netscape site, but if someone could give me a hint or two as to which
| functions/objects/methods i should be looking at it'd be a big help.

| thanks in advance,
