document.selection.createRange()
 

Hello,

i have a form
<form name="ftext" id="ftext">
<textarea id="text" name="text"></textarea>
</form>
now i fill in a few words, lets say 'HelloWorld'. Now i put my focus in this
form between Hello and World because i want JavaScript to fill something in
there by a function called "fillInFormOne()".

and than i have another form:
<form name="another" id="another" onSubmit="fillInFormOne(nr)">
<textarea id="txt" name="txt"></textarea>
</form>
Whats going on in real is more complicated, so please dont ask, why i do it
like this. I made things simple here.

My Problem:
when i go into the textarea of form 2 my form 1 loses focus, so i have to
tell the function in the parameter"nr", where focus was before, so that this
function can edit document.forms['ftext'].elements['text'].value at the
right place between "Hello" and "World".

But how to find this value?
I need something like
document.forms['ftext'].elements['text'].selectionStart.value
Also it should work in Gecko and IE

Thanks for any help on that,
Martin Nadoll

The required `action' attribute is missing.

Remove `.value', and store the reference to the previously focused element
somewhere, e.g.

<script type="text/javascript">
var ref = null;
</script>

<... onfocus="ref = this">

<... onfocus="foo(ref)">

You should avoid naming elements "text", though.

The above (save the `.value') works in Gecko, createRange() (in your Subject
header![1]) works in IE/MSHTML.
