Hi,
does anyone know of any javascript method that does the same job as
document.write( ), but not necessarily at the end of the document? For
instance, insert some text inside an element that has a specific ID
tag?
thanks a lot

ok, I think I need to go back to iframes..
the problem is a very odd one.. pls see below:
function pricing() {
var list = document.forms[0].product;
var selItem = list.value;
var ifr = document.create Element("iframe ");
//ifr.src = "iframes/' + selItem + '.html"; // *** get a 404..
look @ 2 following lines.. this is very weird..
ifr.src = "iframes/' + 'aa' + '.html"; // **** get a 404..
ok, above line is wrong (the quotes..)
however when did this still got 404..
ifr.src = '"iframes/' + 'aa' + '.html"';
I don't see why you even need to place in double quotes. The whole
thing is a string value. The above code statement is equivalent to the
following:
ifr.src = '"iframes/aa.html"';
ok, what confused me is that in TAG (<iframe>) you have to put (I think)
attr under src in quotes (<iframe src="file.html" ..>) is this right? at
any rate not sure this is 100% required so left them out.. but of course
you're right, I'm not even generating iframe w/a conventional tag so I
guess that requirement doesn't apply..
finally got this to work thus:
list = document.forms[0].product;
selItem = list.value;
var ifr = document.create Element("iframe ");
ifr.src = 'iframes/' + selItem + '.html';
ifr.scrolling = 'no';
ifr.style.borde rWidth='0'; // this only stuff that's not working..
It is working. But it's probably not the border you were thinking of.
That border is for placing a border around the entire iframe. And if
that's the case, then you still have what you asked for, a zero border.
But if you wanted something visible, you might also want to set the
borderStyle and the borderColor.
document.getEle mentById("divPr icing").appendC hild(ifr);
problem NOW is that when user goes back to sel obj and selects a diff.
product new iframe gets placed BESIDE current one, not in same place
where other one is :( (which is weird b/c iframe is inside a div
positioned absolutely w/css.. I guess have to do the visible/hidden
thingie w/css...)
again, many thanks for your help..... Frances
Hiding the other frames with css is not a good solution. Consider
this, what if the user continuously selects a different product? Then
the page will continue to append a new child.
What you'll have to do is use the replaceChild method.
document.getEle mentById("id"). appendChild(new Child, oldChild);

The value property of an HTMLSelectEleme nt is specified in the W3C HTML
DOM standard, and is a formalisation of pre-existing behaviour from some
browser implementations . It was not universal at the time of its
standardisation and so its use in place of looking up the value of a
selected option with the selectedIndex property will needlessly
sacrifice browser compatibility. This would not be wise in a script such
as a form validation script that does not itself have a dependency on
other more recent DOM features.

The compound assignment and concatenation operator is +=, you have
written =+, which is assignment and unary plus. Unary plus type-converts
its string operand - "</iframe>" - into the number NaN, and then the
assignment replaces the value of - copy - with that NaN value.

To be clueful, recommendation of getElementByID should be accompanied by
noting that it does not work on all browsers (see FAQ) and that it can
be emulated well enough for some of the others.
if (document.all && !document.getEl ementById) {
document.getEle mentById = function(id) { return document.all[id] } }
And that it is only needed for a browser that is almost 10 years old?
You exaggerate : the system age is less than three-quarters of that.
I said nothing about system age, I said the browser is almost 10 years old.
And considering that IE4.0 was released in October of 1997, that makes
the browser a tad under 8 years old. And in the age of the Web, that is
ancient.
Not everyone uses the latest systems (vulnerable to the latest malware).
Not all latest systems are vulnerable to that malware. It only takes a
little common sense and understanding of your computer to keep it free
of malware.

with my date format are people who have nothing better to whine about

Of course, even that format is not as proper as it would be if it

yes, I tried this, it works.. thank you.. I like it, simpler than other
way... (also thanks for pointing out I had wrong var decl (=+ instead
of +=..)

thank you very much for yr help.... so in order for this to work I have
to put a blank iframe there initially so I can replace it afterwards..
this is how I figured, but unfortunately having some problems...
var selItem;
var ifrCurr;
var div = document.getEle mentById("divPr icing");
// this var not being read inside functions..
// (even if I take out 'var' from declaration..)
function currIF() { // to put a blank iframe..
ifrCurr = document.create Element("iframe ");
ifrCurr.src = 'iframes/blank.html';
//div.appendChild (ifrCurr); // ****** var not being read...
document.getEle mentById("divPr icing").appendC hild(ifrCurr);
// errror on this line
// is null or not an obj... (??)
// no problem w/this line in below function..
}
window.onload=c urrIF();
function pricing() {
selItem = document.getEle mentById("produ ct").value;
var ifr = document.create Element("iframe ");
ifr.src = 'iframes/' + selItem + '.html';
ifr.scrolling = 'no';
ifr.style.borde rWidth='0';
ifr.setAttribut e(selItem, name);
document.getEle mentById("divPr icing").appendC hild(ifr);
// div.appendChild (ifr); // ******* var not being read...
// document.getEle mentById("divPr icing").replace Child(ifr,ifrCu rr);
// can't use this line yet b/c problems w/function above....
}
