I tried 'iframe.body.in nerText' but that did not work.

<iframe name="iframe01" width="100%" height="25%" src="test1.txt" >
</iframe>

<form name="form1">
<textarea name="txt01" cols=80 rows=18>
This is a test
</textarea><br>
<button name="Copy" value="Copy" OnClick="DoCopy ()">Copy</button>
</form>


<script>


function DoCopy()
{
document.forms['form1'].elements['txt01'].value =
document.frames['iframe01'].document.body. innerHTML;
}
</script>



1) Never ever give the names/id using generic html element names
("iframe", "textarea" etc.)

2) <http://www.javascriptt oolbox.com/bestpractices/> see about
addressing frames/form elements - helps a lot.

This does not deal with getting the text from a text document in an iframe
which is what I was after.

Is that really a text/plain document in the iframe? Or a text/html
document? Obviously the DOM is defined for (structured) HTML and XML
documents but not for (unstructured) text documents.
Though some browser (IE, Mozilla too perhaps) might expose a document
with a body for text, see below.

<input type="button" value="Copy"
onclick="DoCopy (this.form.elem ents.textarea, 'iframe')">

[color=blue]
> function DoCopy()[/color]

function DoCopy (textControl, iframeName) {
if (window.frames && window.frames[iframeName] &&
window.frames[iframeName].document &&
window.frames[iframeName].document.body &&
window.frames[iframeName].document.body. innerHTML)
{
textControl.val ue =
window.frames[iframeName].document.body. innerHTML;
}
}

Great, the text appears as a <pre> block, but using InnerText rather than
innerHTML sorts that out and just copies the raw text :)

Thanks alot,

And only works in IE since innerText is IE proprietary code.

Okay, I will have to do a workaround at some point :(

Don't listen to what V'often wrong'K is telling you. There is nothing
wrong in using such names, there is no known side effect in any language
or UA. What is true is that it is a Good Thing to choose names with
meaning; for example, the `textarea' element could be named according
to its expected content.

Try referenceToIfra me.document.bod y.firstChild.fi rstChild.nodeVa lue in
Mozilla/5.0. WFM in Firefox 1.0.7/Linux as an iframe with a plaintext
resource is made available through an embedded HTML document with a
`pre' element containing the resource's content.

Note that innerText (JS is case-sensitive) is an IE-proprietary property.

Yes they are different namespaces.

referenceToIfra me.document.bod y.firstChild.fi rstChild.nodeVa lue

Works in IE too :)

Thanks.

Nice :) However it is not supposed to work in IE/Windows < 5.0 and I'm
not sure about IE/Mac either. W3C DOM support was introduced in IE pretty
late, so you should definitely feature-test it on run time.

Just joking :)

I did think when I wrote that post that the context was odd.
