Unknown runtime error

[sheldonlg]

I have googled for '"Internet Explorer" "Unknown runtime error"' and not
found anything useful. I have the following (for simplicity of
presentation here):

<div><table><tr ><th id="foo"></th></tr></table></div>

In my javascript I have two lines:

var titleObj = document.getEle mentById('foo') ;
titleObj.innerH TML = "Name is bar";

IE6 is throwing an "Unknown runtime error" at the second line.

What can I do about it?

What can I do about it?

Mmmm, do you wait for onloading the page?

The page is already loaded. This occurs when clicking a button on the
page that brings up the div (making it visible, that is). This line is
part of that javascript that presents the box.

You add the text when the table is hidden? and then you make it visible?
If it is so, IE could get angry...

Restore the error, then see what W3's downloadable TIDY (used as a
checker) and also an on-line tester say about it. I predict that you
will then form the habit of using them.

I wish I could do that. However, if I do a "view source", all I see is
the template. This is on an AJAX foundation using php to write the
html. From what I have researched on the web, the validator can't be
used with php, let alone html that is written at run time via AJAX.

If I am wrong, them please enlighten me. I would love to check for
errors by validations. As it is, I found this by taking my code and
cutting and pasting into a dreamweaver window and then manually
indenting and examining it line by line. (I just indented the print
statements as I would have done for the tage).

Ever tried to use MS VS.NET for debugging JS? Try it, and you'll
never want to use anything else. Even the obsolete 7.0 (.NET FW 1.0)
that can be had for next to nothing does the job (or in case you don't
care about Bill Gates' profit, just eMule it). Firefox script
debugger next to it is like Hyundai next to BMW.

And to see dynamically built object html, try entering into IE address
bar javascript:aler t(document.getE lementById('som e id').innerHTML) ;
Works with FF, too.

Thanks. That was [almost] great. The "almost" is because I can't cut
and paste it. If I could do the cut and paste, I could either (a)
format it nicely to see where I may have made a mistake or (b) put it
into a separate html file that I could then validate and have W3C do
that work for me. Is there a variant that would allow me to do that.

BTW, IE changes things slightly. It removes the quotes around things
like class="thisclas s" whereas FF doesn't. However, the formatting in
IE is somewhat better in starting new lines.

I have tried it, and I prefer the MS Script Debugger for JScript, for its

small memory footprint. Never wanting to use anything else would be
nonsense anyway because MS VS.NET can only debug JScript, not JavaScript or

I prefer Firebug for debugging scripts in Firefox; you definitely should try
that.

It attaches to IE and debugs _any_ script currently running - be that
MS-only JScript, plain vanilla JavaScript, or even (cough!) vbscript.

OK, here's a 'greater' implementation that answers your prayer - but
much more heavyweight. You enter into IE address bar
javascript:getI t([some id], [optional true]);
The optional parameter doesn't work with FF due to outerHTML not being
a part of its object model, but setting it to false or just omitting
works.

Sorry, that was copy-paste from a place that uses stub function Get to
getElementById (just to type less - no other benefits). Replace Get
with getElementById to make the code above work - or just add this:

function Get(someId)
{return getElementById( someId);}

Thanks. I am storing this one away for future use. I solved my
problem. It was due to an unclosed tag. So, while I don't need it now,
I am sure I will use it in the future.

Thanks again. I am primarily a server side programmer (php) and Java,
c, etc. I have learned a lot of javascript over these past couple of
months, but I am still quite new to it. My question is that I have used
document.getEle mentById('src') . When is it allowable to leave off the
"document." prefix?

You obviously don't know what JScript and JavaScript are. It would appear
to be best to refrain from posting here until you do.
