Expand textarea to fit a window

[Steve]

Hi,

I'm opening a small window with window.open. I have a textarea there,
and I want it to expand to fit the window as it's resized. How is this
possible? Thanks,

Steve

If there is nothing but that textarea in the popup:
<textarea style="width:10 0%;height:100%" ></textarea>
(perhaps combined with body{margin:0}. ..)

On a page with a 100% wide textarea and a small div along the top I use
this:

onresize=resize d;
function resized(){
scrollTo(0,0);
var y = window.innerHei ght ? window.innerHei ght :
document.body.c lientHeight;
// for better window height, see
// <URL: http://jibbering.com/faq/#FAQ4_9 >
var t = document.forms['f'].txt; // the textarea
t.style.height= Math.max(1,y-txt.offsetTop-1);
}

With proper use of CSS, that script would be not necessary either.

BTW: Your "From" header is invalid.

I was kind of hoping someone would say that. How can I stretch the textarea
to the bottom without knowing the height of the div at the top?

This computer and email client are used by several individuals, and sender's
details keep being changed. Is it better now?

How would one do the opposite? I have a function which creates a button
which pops up a window containing a single textarea of specified size in
rows and columns, and it would be nice to have the window of correct
size to fit it. Under the circumstances, it can be assumed that the
necessary window size will fit within the screen size.

What's the best way of determining the number of lines in a function, in
any browser, given only a reference to the function?

MJDtoYMD.toStri ng().replace(/[^\r]/g, "").length + 1 // \r\n ??
MJDtoYMD.toStri ng().split("\r" ).length

If the FAQ or the Notes have anything on RegExps, a RegExp for newline
could be worth showing; I fear it may need alternatives.
