IE not loading script?

[Tony]

I have a select with an onchange - it works find in Firefox, but in IE
6 I get an error: Object Expected.

I have simplified things drastically, and still get the error.

The HTML:

<select name="viewtrain " id="viewtrain" onchange="viewD etails(this);">
<option value="1">Train 1</option>
<option value="2">Train 2</option>
<option value="3">Train 3</option>
</select>

and the javascript:

function viewDetails(sel )
{
alert('hi');
}

For some reason, this fails. But if I replace viewDetails with an
alert:
<select name="viewtrain " id="viewtrain" onchange="alert (this);">
everything works correctly.

For some reason, it seems that IE isn't 'seeing' viewDetails.

-
OK I did a bit more checking before posting, and it seems that the js
file isn't loading at all - but only in IE. I can't imagine why.
here's the source:

<script type="text/javascript" src="js/CalendarPopup.j s"></script>
<script type="text/javascript" src="js/details.js"></script>
<script type="text/javascript">
ACTIVE_SECTION = 'Late Trains Details';
</script>

The stuff before and after works fine. Only details.js is not loading
- and only in IE.

I'm stumped on this one...

Is it because you're calling details.js but the actual file is called
Details.js with a capital?

That wasn't the problem - I had rechecked the path & capitalization.

Finally figured it out. There was a variable named 'class' in the
file. Apparently, IE doesn't like that. Changing it to 'classname'
fixed the problem.

No ECMAScript-compliant engine likes it if you use reserved words for
identifiers.

Then you are lucky this time. But 'classname' is also reserved; best
to rename it again.

'className' is, not 'classname'.

Not my oracle!

Mine neither :-) I doubt if 'className' would have been supported
anyhow in those browsers.

No, it is not, and neither is `className'.

best to rename it again.

That depends on where that identifier is used. As a *variable name* like
here, it is completely harmless.

I was not referring to the official "Reserved Words"; I used the word
'reserved' outside of that context.

Correct, but as you undoubtedly know better than me, a variable name
is only a property of the window-object. You will want to avoid
confusion and not use things like window.classNam e. A good deal of
programmers will interpret such code as an attempt to influence the
class of the window (if such a thing would exist). Of course your
statement is theoretically true; but it leads to bad habits and
dangerous consequences in practice. Software is not an exact science.

As a *variable name* like here, it is completely harmless.

Is it "completely harmless" to create confusion like that ? No, it
isn't. Better keep things clear when writing code; rule number one as
far as I'm concerned.

Indeed it isn't.
Test these before and afther the mouseovers,
It will confuse anyone but Thomas:

<style type='text/css'>
..x {background-color:blue;}
</style>

<span
id='d1'
classname='z'
onmouseover='th is.className="x "'>
Hi
</span>

<button onclick='alert( document.getEle mentById("d1"). classname)'>
click</button>
<p>
<span
id='d2'
className='z'
onmouseover='th is.className="x "'>
Hi
</span>

<button onclick='alert( document.getEle mentById("d2"). className)'>
click</button>

I just wanted to make things clear to the dedicated reader.

Yes, I do, for your statement is imprecise at best. Variables become
properties of the *Variable Object of the execution context* they have been
declared in, with the DontDelete attribute. That object is the Global
Object only for the global execution context. The Global Object only MAY
have a host-defined property named `window' that refers to the Global Object
again, and even that reference target cannot be taken for granted.

You will want to avoid confusion and not use things like window.classNam e.
A good deal of programmers will interpret such code as an attempt
to influence the class of the window (if such a thing would exist).

^^^^^^^^^^^^^^^ ^^^^^^^^^^^^
There, don't you see? I don't have time to care about clueless programmers
(JFTR, that does not mean "newbies" which is quite different). A Window
object is not an HTML DOM object and therefore is unlikely to have a
*host-defined property* named `className'. I would avoid adding a property
to a host object, but I don't see a problem of using `classname' or
`className' as a variable name, provided the semantics of the identifier fit
the context in which it is used.

Of course your statement is theoretically true; but it leads to bad habits and
dangerous consequences in practice. Software is not an exact science.

To acquire the result of misconceptions about code as a bad habit is the
choice of its reader of that code to make, and not my task to prevent or
avoid. For I would consider it a requirement for survival in this
informational age to be a able to weigh perceived information carefully
before it is being accepted as the truth and become applied knowledge later.

Any piece of source code can cause all kinds of confusion among the
uninitiated. If I were to consider that every time I write a line of code,
I would never ever finish any program because people are so very different,
and so numerous are the different ways in which they can err.

What's that, a clueless programmer ? Someone who doesn't know that
'className' is not a host-defined property of the window-object ? Such
a thing could happen to me too. You can't expect from a programmer to
know all host objects and their properties by head.

Nothing wrong with not knowing something, as long as you know the
places where to look it up.

It *IS* the duty of the programmer to write clear code as to avoid
(possible) ambiguity wherever he can. Do your code readers, your
successor and yourself-in-the-future a favour :)

I'm almost sure you will change your view sooner or later.

Interesting that IE had a problem with 'class', but FireFox didn't.
Does it follow that FireFox is not ECMAScript-compliant?

No, Firefox (i.e. JavaScript 1.5+) issues only a warning:

| (!) class is a reserved identifier

| var class = "foo";
