Hi All,
The following code works in IE but not Firefox. IE produces the
expected "this is more text!" output, but Firefox produces "no more
text". Any ideas why?
<BODY>
<FORM>
<INPUT TYPE=HIDDEN NAME="moreText" VALUE="<PRE>Thi s is more
text!</PRE>">
<SCRIPT LANGUAGE="javas cript">
var m = (document.getEl ementById &&
document.getEle mentById('moreT ext'))
? document.getEle mentById('moreT ext').value
: '<PRE>no more text</PRE>';
document.writel n(m);
</SCRIPT>
</FORM>
</BODY>
FYI, I've tried it with the script both within and outside the form,
and the code behaves identically.
Thanks!

You cannot do a document.write( ) when the page is already loaded and on
screen without destroying the whole page, including the javascript.
Try DOM-inserting (innerHTML or child) to a <div>

The getElementById (as its name implies) finds an element with a matching
ID attribute. IE on windows will also find elements with a matching NAME
attribute, but this is non-standard.

In MSIE only, name and id attributes share one namespace.
Simply add an id="moreText" attribute to the input element.
ciao, dhgm
I changed the NAME= to ID= and everything works as expected.
Thanks for the quick response!

But
for (j=0 ; j<10 ; j++) document.write( j)
shows on the new page 0123456789 so the script is not immediately
destroyed by the first document.write( ). Or, if it is immediately
destroyed on other browsers, I need to do some site re-design.
The original page is immediately destroyed, so all input controls needed
must be read before the first such document.write( )

This is a true statement, but it doesn't apply to the original poster
becuase the page hasn't been loaded since the </body> hasn't been
encountered.
I added the id tag to make it work in more browsers.
<BODY>
<FORM>
<INPUT TYPE=HIDDEN NAME="moreText" id="moreText" VALUE="<PRE>Thi s is
more
text!</PRE>">
<SCRIPT LANGUAGE="javas cript">
var m = (document.getEl ementById &&
document.getEle mentById('moreT ext'))
? document.getEle mentById('moreT ext').value
: '<PRE>no more text</PRE>';
document.writel n(m);

You could make it work in even more browsers if you used the forms
collection and referenced the form element by its name attribute. If for
no other reason that there are more browsers that support the forms
collection than browsers that support document.getEle mentById
var m = (document.forms &&
document.forms['moreText'] &&
document.forms['moreText'].value)
? document.forms['moreText'].value
: '<pre>No More Text</pre>';
document.write( m)

My fingers get ahead of my brain sometimes:

document.forms['formName'].elements['moreText'] &&
document.forms['formName'].elements['moreText'].value)
? document.forms['formName'].elements['moreText'].value

Possibly a tad *too* concise Dietmar ;-)
I'm certain the following is what was intended:
[That method works in]... MSIE only, [the W3C HTML specification
states that] name and id attributes share one namespace.
Which the IE developers seem to have interpreted as "let's treat
ID and NAME as if they are the same thing - but not always".

My AJAX application paints data into about 500 cells with unique ID
every 10 seconds. I am using document.getElementById() to find the

Can anyone suggest any speed improvements for painting data into a
